A method for highthroughput fabrication of such gaps is first presented, and then peculiar optical responses โ€“ anomalous resonance shifts and a large Ohmic absorption โ€“ are experimentally and theoretically realized. Also, wet etching of a gap spacer within a 5 nm gap is demonstrated, enabling aqueous nano-optic experiments below 10 nm scale. This comprehensive study on terahertz gap plasmon and nanogaps is expected to greatly benefit convergence of chemistry or bio-chemistry with nano-optics, especially in sub-10 nm regime.I.

Thus, in this thesis, the three hypotheses on PVS theory were mainly focused to prove for its distinguishing features and at the same time, suggest a new analysis method to make us to understand the complexity of this system from a new perspective. First, in order to PVS accepted as a liquid flowing system, there have always been two major issues coming up. The first one was directly to show the flow of liquid in PVS and the second was to explain why it was not observed in the conventional histological analysis of animal tissues. In order to find the answers to those, we injected fluorescent nanoparticles (FNPs) into a primo node and traced them along primo vessels which was located in the inside a fat tissue which is parallel to the linea alba in the parietal side of the abdominal wall. In previous experiment, the simple flow of injected staining dye (alcian blue) was observed. However, in this experiment, we could possibly trace the flow of FNPs to other subsystems of the PVS. Not just that in this work, we could give a small clue as to why PVS was difficult to observe in conventional histology. In our previous work, we proposed the importance for finding an effective method to find the PVS in skin and need for study on the ultrastructure of the primo vessel (PV). So, in following chapters, we investigated the detailed morphological features of PV inside a lymph vessel with a transmission electron microscope (TEM) and compared the results with the previous study of the PV found on the surfaces of internal organs. These data confirm that the subsystem of PV is found in different parts of body revealed the similarity to one another. Lastly, we focused on explaining the newly developed analysis methods of the acupuncture points (APs) located in the skin of the mouse. In several studies, many of them were still described between MCs and APshowever, they did not provide the answer for the reason. By studying the mast cells (MCs) distribution and densities of the whole mouse ventral skin, we used this information to infer the locations, sizes and depths of the skin layers of APs. This type of estimation was done first time. The methods used in this study can be useful to investigate further gross anatomical features of APs. Also, due to the significant roles of MCs in our body, it is clearly implied that acupuncture plays an important role in MCs in the treatment of diseases. By having the more precise knowledge of skin AP locations and sizes to submillimeter precision, along with their cytological characterizations, would provide significant contributions to both scientific investigations and further acupuncture treatment.Acupuncture has been a major medical practice for thousands of years in China, Korea, and Japan, yet the mechanism underlying acupuncture has still not been unambiguously identified on a scientific basis. From the many previous studies, the known anatomical structure corresponding to the classical acupuncture points and meridians has been presented as the Primo Vascular System (PVS), which was first discovered by Bong Han Kim in early1960. It is being introduced in public as a newly-discovered third circulatory system on par with the circulatory and lymphatic system. Despite its potential importance in health-related fields, it has been ignored for a long time. Only recently, researchers have been carrying out a lot of well-designed research studies to investigate its physical and physiological peculiarity of acupuncture system based on the anatomical and scientific bases, but still it has not been identified fully enough. And even results achieved from experiments performed under the Kims theoryChapter 1.

Nano-slot antennas, metallic film with nanometer-sized slots, are known to show strong resonance at certain frequency, and sensitivity to the dielectric environment. Liquid thin layer is formed using spin-coated PDMS and patterned silicon oxide, which prevent liquids from smearing out. In the presence of liquids the transmission spectra of nano-slot antennas show large amplitude modulations and peak shifts according to the dielectric properties of the liquids. The tendency becomes larger with smaller antenna width. With further optimizations in sealing and antenna structure, this scheme is expected to open up the possibility of measuring much more minute samples, such as a few-layer molecule layer.Contents 1.

In addition, from the 1990s, intimate partner violence has begun to be treated as a public health problem as studies supported the fact that intimate partner violence caused a wide range of health problems through diverse pathways. Meanwhile, the characteristics of womenโ€™s labor force participation are unstable and low-wage, stalled career after marriage or childbirth in Korea Against this background, this study aims to analyze how women's employment status and income affect women's experiences of intimate partner violence. As a data source, five-year data from 2013 to 2017 of the Korean Welfare Panel were used, which included 2,096 married women aged between 19 to 60. First, the chi-square test was conducted to test whether women experienced intimate partner violence differently by their general characteristics in 2013 and 2017, and the result showed significant differences in the prevalence of IPV when women had casual jobs and women were disabled. Second, analyzing the five-year data using difference generalized method of moments, it was confirmed that the frequency of intimate partner violence toward women increased when women's employment status was daily workers, unpaid family workers, unemployed, and economically inactive population. And the higher womenโ€™s relative income, the higher the prevalence of IPV. Third, the result of analyzing the effect of women's employment status and income on intimate partner violence by their husbandsโ€™ gender-role ideology is that the risk of intimate partner violence increased significantly when women were unemployed, economically inactive populations or daily workers than having regular jobs only when their husbandโ€™s gender-role ideology was relatively unequal. Womenโ€™s relative income significantly increased violence no matter their husbandโ€™s gender-role ideology was relatively equal or unequal. The result of this study suggests that improving women's employment stability can reduce violence from their spouses, while explaining that women with unstable employment status could be at relatively high risk of intimate partner violence, suggesting that economic gender equality could contribute to reduce intimate partner violence, which can be used as data supporting women suffered by intimate partner violence.์ œ 1 ์žฅ ์„œ ๋ก  5 ์ œ 1 ์ ˆ ์—ฐ๊ตฌ์˜ ๋ฐฐ๊ฒฝ 5 ์ œ 2 ์ ˆ ์—ฐ๊ตฌ์˜ ๋ชฉ์  9 ์ œ 2 ์žฅ ์ด๋ก ์  ๋ฐฐ๊ฒฝ๊ณผ ์„ ํ–‰์—ฐ๊ตฌ ๊ณ ์ฐฐ 10 ์ œ 1 ์ ˆ ๋ฐฐ์šฐ์žํญ๋ ฅ 10 ์ œ 2 ์ ˆ ๋ฐฐ์šฐ์žํญ๋ ฅ๊ณผ ์‚ฌํšŒ๊ฒฝ์ œ์  ์ง€์œ„์˜ ๊ด€๊ณ„ 13 ์ œ 3 ์žฅ ์—ฐ๊ตฌ๋ฐฉ๋ฒ• 17 ์ œ 1 ์ ˆ ์—ฐ๊ตฌ ์ž๋ฃŒ์› ๋ฐ ๋Œ€์ƒ 17 ์ œ 2 ์ ˆ ๋ณ€์ˆ˜์˜ ์ •์˜ 18 ์ œ 3 ์ ˆ ๋ถ„์„๋ฐฉ๋ฒ• 23 ์ œ 4 ์žฅ ์—ฐ๊ตฌ ๊ฒฐ๊ณผ 26 ์ œ 1 ์ ˆ ์ผ๋ฐ˜์  ํŠน์„ฑ์— ๋”ฐ๋ฅธ ๋ฐฐ์šฐ์ž ํญ๋ ฅ ํ”ผํ•ด ๊ฒฝํ—˜ ์—ฌ๋ถ€์˜ ์ฐจ์ด 26 ์ œ 2 ์ ˆ ์—ฌ์„ฑ์˜ ๊ณ ์šฉ์ง€์œ„ ๋ฐ ์†Œ๋“์ด ๋ฐฐ์šฐ์ž ํญ๋ ฅ ํ”ผํ•ด์— ๋ฏธ์น˜๋Š” ์˜ํ–ฅ 41 ์ œ 3 ์ ˆ ๋ฐฐ์šฐ์ž ๋‚จ์„ฑ์˜ ์„ฑ์—ญํ•  ์ธ์‹ ์ˆ˜์ค€๋ณ„ ์—ฌ์„ฑ์˜ ๊ณ ์šฉ์ง€์œ„์™€ ์†Œ๋“์ด ๋ฐฐ์šฐ์ž ํญ๋ ฅ ํ”ผํ•ด์— ๋ฏธ์น˜๋Š” ์˜ํ–ฅ 44 ์ œ 4 ์ ˆ ์—ฌ์„ฑ์˜ ๊ณ ์šฉ์ง€์œ„ ๋ฐ ์†Œ๋“์ด ์œ ํ˜•๋ณ„ ๋ฐฐ์šฐ์ž ํญ๋ ฅ ํ”ผํ•ด์— ๋ฏธ์น˜๋Š” ์˜ํ–ฅ 46 ์ œ 5 ์žฅ ๊ณ ์ฐฐ ๋ฐ ๊ฒฐ๋ก  48 ์ œ 1 ์ ˆ ์—ฐ๊ตฌ์˜ ๊ฒฐ๋ก  ๋ฐ ํ•จ์˜ 48 ์ œ 2 ์ ˆ ์—ฐ๊ตฌ์˜ ํ•œ๊ณ„ ๋ฐ ์ œ์–ธ 54์„
