Since the 1950s, the maximal functions defined by averages have been extensively studied in the field of classical harmonic analysis and a huge literature has been devoted to the subject. In 1976, Stein proved his seminal result: LpL^p bound on the spherical maximal operator on the optimal range for every dimension bigger than 2. Its two-dimensional counterpart, the bound on the circular maximal function, turned out to be more difficult since the traditional L2L^2 based argument did not work. In 1986, however, Bourgain settled the problem by proving his celebrated theorem: the circular maximal operator is bounded on LpL^p for p>2p>2. In this thesis, we prove three results which strengthen Bourgains circular maximal theorem. First, we establish on the sharp range of p,qp,q the LpL^p--LqL^q boundedness of the circular maximal operator on the Heisenberg group for Heisenberg radial functions. Secondly, we obtain the sharp LpL^p--LqL^q boundedness of the two-parametric maximal operator defined by averages over tori. Lastly, we prove LpL^p estimates on the elliptic maximal operators which are multiparametric maximal operators given by averages over ellipses.κ·ΉλŒ€ ν•¨μˆ˜μ— λŒ€ν•œ 계츑은 νŽΈλ―ΈλΆ„λ°©μ •μ‹, κΈ°ν•˜ν•™μ  츑도이둠, 쑰화해석학과 같은 μˆ˜λ¦¬ν•΄μ„ν•™μ˜ μ—¬λŸ¬ λΆ„μ•Όμ˜ λ¬Έμ œμ—μ„œ μ€‘μš”ν•œ 역할을 ν•œλ‹€. 1950λ…„λŒ€ 이후, ν‰κ· μœΌλ‘œ μ •μ˜λœ κ·ΉλŒ€ ν•¨μˆ˜λŠ” 고전적 쑰화해석학 λΆ„μ•Όμ—μ„œ κ΄‘λ²”μœ„ν•˜κ²Œ μ—°κ΅¬λ˜μ–΄μ™”κ³ , ν˜„μž¬ 이 주제의 연ꡬ에 κ΄€λ ¨ν•œ λ°©λŒ€ν•œ λ¬Έν—Œμ΄ μ‘΄μž¬ν•œλ‹€. 1976년에 μŠ€νƒ€μΈμ€ `3 μ΄μƒμ˜ λͺ¨λ“  μ°¨μ›μ—μ„œ ꡬ면 κ΅­λŒ€ ν•¨μˆ˜μ˜ LpL^p 계츑'을 규λͺ…ν•˜λŠ” 개창적 κ²°κ³Όλ₯Ό 증λͺ…ν•˜μ˜€λ‹€. 2차원 λ¬Έμ œμ— ν•΄λ‹Ήν•˜λŠ” 원 κ·ΉλŒ€ ν•¨μˆ˜μ˜ μœ κ³„μ„±μ€, 고전적인 L2L^2 λ°©λ²•μ˜ ν•œκ³„λ‘œ μΈν•˜μ—¬ 맀우 μ–΄λ €μš΄ κ²ƒμœΌλ‘œ μ•Œλ €μ Έ μžˆμ—ˆλ‹€. κ·ΈλŸ¬λ‚˜ 1986년에 λΆ€λ₯΄κ°±μ€ `원 κ·ΉλŒ€ μ—°μ‚°μžλŠ” ppκ°€ 2보닀 클 λ•Œ LpL^pμ—μ„œ μœ κ³„μ΄λ‹€'λΌλŠ” 그의 유λͺ…ν•œ 원 κ·ΉλŒ€ ν•¨μˆ˜ 정리λ₯Ό 증λͺ…ν•¨μœΌλ‘œμ¨ 이 λ¬Έμ œμ— λ§ˆμΉ¨ν‘œλ₯Ό μ°μ—ˆλ‹€. 이 ν•™μœ„ λ…Όλ¬Έμ—μ„œλŠ” λΆ€λ₯΄κ°± 원 κ·ΉλŒ€ ν•¨μˆ˜ 정리λ₯Ό λ”μš± κ°•ν™”ν•˜λŠ” μ„Έ 가지 κ²°κ³Όλ₯Ό 증λͺ…ν•œλ‹€. 첫째, ν•˜μ΄μ  λ² λ₯΄κ·Έ κ΅° μœ„μ—μ„œμ˜ 원 λŒ€μΉ­ ν•¨μˆ˜μ— λŒ€ν•΄μ„œ 원 κ·ΉλŒ€ μ—°μ‚°μžμ˜ LpL^p--LqL^q μœ κ³„λ₯Ό 졜적 p,qp,q μ˜μ—­μ—μ„œ μ–»λŠ”λ‹€. λ‘˜μ§Έ, μ›ν™˜μ²΄ μœ„μ˜ 평균에 μ˜ν•΄ μ •μ˜λœ 2개의 λ§€κ°œλ³€μˆ˜λ₯Ό κ°€μ§€λŠ” κ·ΉλŒ€ μ—°μ‚°μžμ˜ 졜적 LpL^p--LqL^q μœ κ³„μ„±μ„ 규λͺ…ν•œλ‹€. λ§ˆμ§€λ§‰μœΌλ‘œ, 타원에 μ˜ν•΄ μ •μ˜λ˜λŠ” λ‹€μ€‘λ³€μˆ˜ κ·ΉλŒ€ μ—°μ‚°μžμΈ 타원 κ·ΉλŒ€ μ—°μ‚°μžμ˜ LpL^p 계츑을 증λͺ…ν•œλ‹€.Abstract i 1 Introduction 1 1.1 Maximal averages over rectangles 1 1.2 Maximal averages over submanifolds 3 1.3 The circular maximal function and L^p improving property 5 1.4 Maximal averages on the Heisenberg group 6 1.5 Two parameter maximal averages over tori 7 1.6 Multiparameter maximal averages over ellipses 9 1.7 Notations 10 2 Preliminaries 12 2.1 Decoupling inequalities 12 2.2 Local smoothing estimates of the wave operator 16 3 The Heisenberg circular maximal operator 19 3.1 Heisenberg radial functions and main estimates 21 3.2 Local maximal estimates 23 3.3 Global maximal estimates 27 3.4 Proof of main estimates 30 3.5 Proof of Proposition 3.1.131 3.6 Proof of Proposition 3.1.2 34 3.7 Sharpness of the range of p, q 41 4 Two parameter averages over tori 42 4.1 Comparison with one parameter maximal average 43 4.2 Local smoothing estimates of averages over tori 44 4.3 Two parameter propagator 45 4.4 Estimates for the averaging operator A_s^t 50 4.5 Global maximal estimates 58 4.6 Local maximal estimates 64 4.7 Proof of smoothing estimates 66 4.8 Optimality of the estimates 75 5 Multiparameter averages over ellipses 79 5.1 Local smoothing estimates for averaging operators over ellipses. 80 5.2 Proof of maximal bounds 82 5.3 Variable coe cient decoupling inequalities 87 5.4 Proof of local smoothing estimates 92 5.5 Proof of Theorem 5.3.2 99 5.6 Optimality of the estimates 106 Abstract (in Korean) i Acknowledgement (in Korean) iiλ°•

    ν•™μœ„λ…Όλ¬Έ (박사)-- μ„œμšΈλŒ€ν•™κ΅ λŒ€ν•™μ› : 화학생물곡학뢀, 2016. 2. μ•ˆκ²½ν˜„.Coating fluids that include highly size-asymmetric particles are widely used in many applications such as Li-ion batteries, multi-layer ceramic capacitors, and electrical conductors. They include different types of particles to improve the performance of the product. In these liquids, the size of the particles is very differentone is micrometer and the other nanometer scale, for example. Because of distinctively different size of the particles, these bimodal dispersions show more complex flow behavior compared to colloids of a single size. However, most studies for bi-modal dispersions assumed well-stabilized nanoparticles, thus they have not been relevant to the behavior of the materials used in industry. In this study, a model system consisting of two kinds of particles with highly asymmetric size was designed to offer a valuable description of complex behavior of the slurries, using a suspension consisting of polystyrene latex (500 nm) and alumina-coated silica (12 nm) particles. The surface potential of small particles was tuned by varying the solution pH, causing them to be repulsive to each other, attractive to each other, and oppositely charged to the large particles, while the large particles remained electrostatically stabilized. The effect of addition of small particles on the rheological properties of bimodal suspensions was investigated in terms of surface chemistry and concentration of small particles. The rheological properties were dramatically changed from viscous to gel-like depending on the surface potential and concentration of small particles. A colloidal gel was induced by small particles when the small particles had the opposite charge to the large particles and a volume fraction of , and when the small particles were attractive to each other above a critical threshold, . Cryo-SEM distinguished the gel structures to be either short bridging gels produced by oppositely charged small particles, or long bridging gels or dense gels produced by attractive small particles. On the basis of this rheological behavior and microstructure, a phase diagram of highly size-asymmetric bimodal colloids was presented with respect to the surface chemistry and concentration of small particles. When the mutually attractive small particles are added to suspension of highly charged large particles, a new type of colloidal gel was induced which is not described by the typical power - law scaling for fractal clusters. Their elastic moduli have a unique scaling behavior on particle volume fraction with two distinct power - law indices. The unique scaling behavior arises from the non-fractal networks of large particles that are bridged by small particle clusters in the region between the lower and the upper critical boundary of small particle volume fraction. Because the model fluid in this study is similar to the slurries used in industry with respect to the size ratio, the range of concentration, and the surface potential, it is expected that the slurries encountered in practice have analogous mechanical behavior and microstructure to this model fluid. This study consequently provides a guideline for the design of such complex fluids and understanding of their complex flow behavior.Chapter 1. Introduction 1 1.1.

Since 2010, the average growth rate of the cross-border online shopping market was 40~50% per year. In addition to Koreans purchasing foreign goods via online channel, Yeok-jikgu or inverse cross-border online shopping is also prevalent phenomenon. Cross-border online shopping is no longer a trendy act amongst 20s~40s female consumers, but has become a strong distributional channel as well as a global consumer behavior. Among many categories being imported via cross-border online shopping channel, fashion items including clothing & apparel(19%), shoes(13%), and cosmetics(11%) rank number one. Although cross-border online shopping clearly is an issue that reflects changes in fashion industry and distribution channel, and consumer behavior, academic researches related to cross-border online shopping are very limited. The purpose of this study is to find out the factors affecting fashion consumers purchasing intentions on cross-border online shopping. In order to empirically prove research questions, this study adopted the three outshopping motivation dimensionsutilitarian, social, and hedonic. Furthermore, the moderating effect of consumers perceived risk between cross-border online shopping motivation and behavioral intention was tested. Online survey was conducted on Korean female consumers in their 20s to 40s, with the experience of purchasing fashion goods through cross-border online shopping channel within a year. The findings of analysis are the following. First, the three motivations have positive effects on cross-border online shopping purchase intention. Plus, fashion consumers are affected greatly by hedonic motivation compared to utilitarian and social motivations. Second, perceived risk does not have negative effect on cross-border online shopping purchase intention. Cross-border online shopping uses the Internet as transaction channel, and many consumers well adapted, long-time online shoppers. Thus, fashion consumers tend to shop through cross-border online shopping channel even if they perceive risk, as long as there is utilitarian motivation. Finally, moderating effect of perceived risk exists between utilitarian motivation and cross-border online shopping purchase intention. The interaction effect of the independent and moderating factor proved that only utilitarian motivation is moderated with perceived risks when consumers are purchasing fashion goods on cross-border online shopping channel. This study found the motivational and moderating factors that influence fashion consumers to shop through cross-border online shopping channel. It academically contributes by extending the research range of cross-border online shopping into fashion. Moreover, marketers and retailers should take note that fashion consumers are affected most by hedonic motivation when shopping in cross-border online malls.제 1 μž₯ μ„œ λ‘  1 제 1 절 μ—°κ΅¬μ˜ ν•„μš”μ„± 및 의의 1 제 2 절 μ—°κ΅¬μ˜ λͺ©μ  7 제 3 절 μ—°κ΅¬μ˜ ꡬ성 8 제 2 μž₯ 이둠적 λ°°κ²½ 9 제 1 절 아웃쇼핑과 온라인 해외직ꡬ 9 1. 아웃쇼핑과 온라인 ν•΄μ™Έμ§κ΅¬μ˜ κ°œλ… 9 2. 아웃쇼핑과 온라인 ν•΄μ™Έμ§κ΅¬μ˜ 동기 14 제 2 절 μœ„ν—˜ 지각 22 1. μœ„ν—˜ μ§€κ°μ˜ κ°œλ… 및 선행연ꡬ 22 2. μœ„ν—˜ μ§€κ°μ˜ 쑰절효과 24 제 3 절 ν™•μž₯된 ν†΅ν•©κΈ°μˆ μˆ˜μš©μ΄λ‘  26 1. ν™•μž₯된 ν†΅ν•©κΈ°μˆ μˆ˜μš©μ΄λ‘ μ˜ κ°œλ… 26 2. ν™•μž₯된 ν†΅ν•©κΈ°μˆ μˆ˜μš©μ΄λ‘ μ— κ΄€ν•œ 선행연ꡬ 31 제 3 μž₯ 연ꡬ 방법 및 절차 36 제 1 절 연ꡬ κ°€μ„€ 및 연ꡬ λͺ¨ν˜• 36 1. 연ꡬ 문제 및 κ°€μ„€ μ„€μ • 36 2. 연ꡬ λͺ¨ν˜• 38 제 2 절 싀증적 연ꡬ 방법 39 1. 연ꡬ λŒ€μƒ 및 방법 39 2. 섀문지 λ¬Έν•­μ˜ ꡬ성 39 제 3 절 자료 μˆ˜μ§‘ 및 뢄석 방법 44 1. 자료의 μˆ˜μ§‘κ³Ό ν‘œλ³Έμ˜ ꡬ성 44 2. 자료의 뢄석 방법 44 제 4 μž₯ 연ꡬ κ²°κ³Ό 및 λ…Όμ˜ 46 제 1 절 쑰사 λŒ€μƒμž νŠΉμ„± 46 1. 인ꡬ톡계학적 νŠΉμ„± 46 2. νŒ¨μ…˜ μ œν’ˆ 온라인 해외직ꡬ κ²½ν—˜ 47 제 2 절 μΈ‘μ • λ³€μˆ˜μ˜ μ‹ λ’°μ„± 및 타당성 검증 52 1. 각 λ³€μˆ˜μ— λŒ€ν•œ μ‹ λ’°μ„± 및 타당성 검증 53 제 3 절 λ³€μˆ˜μ˜ κΈ°μˆ ν†΅κ³„ 56 제 4 절 효용적 동기, μ‚¬νšŒμ  동기, 쾌락적 동기가 νŒ¨μ…˜ μ œν’ˆ 온라인 해외직ꡬ ν–‰λ™μ˜λ„μ— λ―ΈμΉ˜λŠ” 영ν–₯ 57 제 5 μž₯ κ²° λ‘  64 제 1 절 μš”μ•½ 및 κ²°λ‘  64 제 2 절 μ—°κ΅¬μ˜ μ‹œμ‚¬μ  67 1. μ—°κ΅¬μ˜ 학문적 μ‹œμ‚¬μ  67 2. μ—°κ΅¬μ˜ 싀무적 μ‹œμ‚¬μ  68 제 3 절 μ—°κ΅¬μ˜ ν•œκ³„ 및 후속 연ꡬλ₯Ό μœ„ν•œ μ œμ–Έ 70 μ°Έκ³ λ¬Έν—Œ 72 Abstract 86 λΆ€ 둝 89Maste

    Absence of Cytosolic 2-Cys Prx Subtypes I and II Exacerbates TNF-Ξ±-Induced Apoptosis via Different Routes

    There are abundant peroxiredoxin (Prx) enzymes, but an increase of cellular H2O2 level always happens in apoptotic cells. Here, we show that cellular H2O2 switches different apoptosis pathways depending on which type of Prx enzyme is absent. TNF alpha-induced H2O2 burst preferentially activates the DNA damage-dependent apoptosis pathway in the absence of PrxI. By contrast, the same H2O2 burst stimulates the RIPK1-dependent apoptosis pathway in the absence of PrxII by inducing the destruction of cIAP1 in caveolar membrane. Specifically, H2O2 induces the oxidation of Cys308 residue in the cIAP1-BIR3 domain, which induces the dimerization-dependent E3 ligase activation. Thus, the reduction in cIAP level by the absence of PrxII triggers cell-autonomous apoptosis in cancer cells and tumors. Such differential functions of PrxI and PrxII are mediated by interaction with H2AX and cIAP1, respectively. Collectively, this study reveals the distinct switch roles of 2-Cys Prx isoforms in apoptosis signaling.ope

    So far, type Shamanic Epic has been interpreted mainly as a family myth. However, considering that many myths use family relationships as symbols to explain various themes, since it is a family incident, it is not displayed only by talking about the family. There is also a need to explore possibilities that have different meanings. When classified according to the type of story, it is roughly divided into Salpoori and Sungshingut in the northern region, Chilseongpoori in the southwestern region, and MunjonBonpoori in Jeju Island. In all versions, the conflict between the stepmother and the child of the ex-wife appears in a major event. For Chilseongpoori and MunjonBonpoori, the separation of the parents and the resurrection of the real mother were added. The conflict between the stepmother and the child of the ex-wife was compared to the story of the origin of the golden fleece in ancient Greece, which is similar in content. The story of the origin of the golden fleece is about eliminating famine in the city, and trying to solve the problem with a ritual of human sacrifice. The story shows ritual traces of the murder of a prince on behalf of the king, who is responsible for resolving famine, was interpreted as being replaced by a royal woman represented by stepmother. She had an allegory of the Hinuwelle type, because she was a redemption for the abundance of crops. The separation and resurrection of the real mother shows that the range of redemption of the stepmother has been extended to the real mother. When redeeming, the original offering must be hidden from God. So the real mother was separated from her family and hid to death, but when stepmother died and the redemption was over, she was revived and redisplayed. The stepmother, who had been read as a wicked woman, could be read again as a redemptor for a family. When interpreted as an ancient human sacrifice ritual, the stepmother was a sacred being who promised family affluence and prosperity as a sacrifice

    Secondhand Smoke Exposure and Depressive Symptoms among Korean Adolescents: JS High School Study

    INTRODUCTION: Increasing evidence suggests that secondhand smoke exposure (SHSE) may affect not only physical health, but also mental health. Therefore, we evaluated the association between SHSE and depressive symptoms among Korean adolescents. METHODS: The JS High School Study enrolled 1071 high school freshmen from a rural community of South Korea. The current analysis was limited to 989 adolescents (495 male and 494 female adolescents), after excluding 48 ever-smokers, 3 students with physician-diagnosed depression, and 31 students who did not complete the depression questionnaire. SHSE was assessed using a self-reported questionnaire and was classified into three groups: none, occasional exposure, and regular exposure. Depressive symptoms were assessed according to the Beck Depression Inventory (BDI) score, ranging from 0 to 63, and the presence of depressive symptoms was defined as a BDI score β‰₯10. RESULTS: Overall, adolescents with SHSE were more likely to have depressive symptoms than those without SHSE (p = 0.042).In a sex-specific analysis treating the BDI score as a continuous variable, regular SHSE was independently associated with higher BDI scores in male adolescents (Ξ² = 2.25, p = 0.026), but not in female adolescents (Ξ² = 1.11, p = 0.253). Compared to no SHSE, the odds ratio for having depressive symptoms among male adolescents with regular SHSE was 2.17 (95% confidence interval, 1.11 to 4.25) after adjusting for age, body mass index, and study year, and 3.65 (95% confidence interval, 1.52 to 8.73) after adjusting for age, body mass index, study year, exercise, and household income. CONCLUSION: Regular exposure to secondhand smoke was associated with having depressive symptoms among Korean male adolescents.ope
