The Role of Empowerment, Organizational Commitment and Working Environment on Job Performance in AAA Non-Profit Organization

Empowerment has become a big part of our today’s job performance. For organizations in a highly competitive environment, empowerment ensures sustained productivity and creating a committed workforce. This research study assesses the needs of three factors that help to enhance individual’s job performance in the non-government organization: empowerment, working environment, and organizational commitment. A mixed research methodology was used to study the whole population in the organization. All 28 local employees responded to the survey questionnaire for quantitative research, whereas 8 key employees were selected to participate in an individual interview. The quantitative data was analyzed using descriptive analysis and PNI Modified. The qualitative data was analyzed using inter-coding method. The results from PNI Modified show that empowerment, working environment, and organizational commitment are the factors that have to be prioritized. The qualitative data used appreciative inquiry (AI) to explore the topic of empowerment, working environment and organizational commitment. Based on the overall results, the current situation of job performance is favorable, but PNI Modified suggested that some factors should be prioritized in order to enhance individual’s job performance. Therefore, strategies are  presented based on the findings

Modification of Dentofacial Growth Associated with Goldenhar Syndrome

The rare developmental defect, Goldenhar syndrome is characterized by complex craniofacial and dentofacial anomalies. Here we describe the successful orthodontic treatment of a 5-year-old Japanese Goldenhar syndrome patient with mild facial asymmetry, right microtia, right-side hearing loss, and tongue-thrusting by a modification of dentofacial growth using a non-surgical orthopedic treatment approach. Improvement of the vertical discrepancies on the affected side and canted occlusal plane as well as mandibular deviation were achieved with a functional orthopaedic approach. Stable and acceptable occlusion were obtained over the 32-month post-retention period. A non-surgical orthodontic treatment approach offers satisfactory facial aesthetic outcomes in Goldenhar syndrome

Predictors of sleep quality: Depression, anxiety, and sleep self-efficacy

The objective of the current study was to examine the relationship between depression, anxiety, sleep self-efficacy, and sleep quality among college students by using both objective measures and self-reported data. Participants included 27 undergraduate students from a small liberal arts college who wore ActiGraph wristbands for a period of seven nights. Participants also completed anxiety, depression, sleep self-efficacy, and subjective sleep quality scales. Results indicated that higher sleep self-efficacy scores were associated with lower anxiety and depression scores. Higher subjective sleep quality was associated with higher sleep self-efficacy scores and lower depression and anxiety scores. This study supports the need for emphasis on the importance of improving subjective sleep quality which in turn may influence mental health issues

Role of intracellular Ca2+–based mechanotransduction of human periodontal ligament fibroblasts

Human periodontal ligament (hPDL) fibroblasts are thought to receive mechanical stress (MS) produced by orthodontic tooth movement, thereby regulating alveolar bone remodeling. However, the role of intracellular calcium ([Ca2+]i)‐based mechanotransduction is not fully understood. We explored the MS‐induced [Ca2+]i responses both in isolated hPDL fibroblasts and in intact hPDL tissue and investigated its possible role in alveolar bone remodeling. hPDL fibroblasts were obtained from healthy donors' premolars that had been extracted for orthodontic reasons. The oscillatory [Ca2+]i activity induced by static compressive force was measured by a live‐cell Ca2+ imaging system and evaluated by several feature extraction method. The spatial pattern of cell‐cell communication was investigated by Moran's I , an index of spatial autocorrelation and the gap junction (GJ) inhibitor. The Ca2+‐transporting ionophore A23187 was used to further investigate the role of [Ca2+]i up‐regulation in hPDL cell behavior. hPDL fibroblasts displayed autonomous [Ca2+]i responses. Compressive MS activated this autonomous responsive behavior with an increased percentage of responsive cells both in vitro and ex vivo . The integration, variance, maximum amplitude, waveform length, and index J in the [Ca2+]i responses were also significantly increased, whereas the mean power frequency was attenuated in response to MS. The increased Moran's I after MS indicated that MS might affect the pattern of cell‐cell communication via GJs. Similar to the findings of MS‐mediated regulation, the A23187‐mediated [Ca2+]i uptake resulted in the up‐regulation of receptor activator of NF‐κB ligand (Rankl) and Sost along with increased sclerostin immunoreactivity, suggesting that [Ca2+]i signaling networks may be involved in bone remodeling. In addition, A23187‐treated hPDL fibroblasts also showed the suppression of osteogenic differentiation and mineralization. Our findings suggest that augmented MS‐mediated [Ca2+]i oscillations in hPDL fibroblasts enhance the production and release of bone regulatory signals via Rankl/Osteoprotegerin and the canonical Wnt/β‐catenin pathway as an early process in tooth movement–initiated alveolar bone remodeling.—Ei Hsu Hlaing, E., Ishihara, Y., Wang, Z., Odagaki, N., Kamioka, H.

A Ciphertext Policy Attributes-based Encryption Scheme with Policy Revocation

There are a lot of data exchanges among the parties by using cloud computing. So data protection is very important in cloud security environment. Especially, data protection is needed for all organization by security services against unauthorized accesses. There are many security mechanisms for data protection. Attributes-based Encryption (ABE) is a one-to-many encryption to encrypt and decrypt data based on user attributes in which the secret key of a user and the ciphertext are dependent upon attributes. Ciphertext policy attributes-based encryption (CP-ABE), an improvement of ABE schemes performs an access control of security mechanisms for cloud storage. In this paper, sensitive parts of personal health records (PHRs) are encrypted by ABE with the help of CP-ABE. Moreover, an attributes-based policy revocation case is considered as well as user revocation and it needs to generate a new secret key. In proposed policy revocation case, PHRs owner changes attributes policy to update available user lists. A trusted authority (TA) is used to issue secret keys as a third party. This paper emphasizes on key management and it also improves attributes policy management and user revocation. Proposed scheme provides a full control on data owner as much as he changes policy. It supports a flexible policy revocation in CP-ABE and it saves time consuming by comparing with traditional CP-ABE

Loading history changes the morphology and compressive force-induced expression of receptor activator of nuclear factor kappa B ligand/osteoprotegerin in MLO-Y4 osteocytes

Background In this study, we investigated the effect of the mechanical loading history on the expression of receptor activator of nuclear factor kappa B ligand (RANKL) and osteoprotegerin (OPG) in MLO-Y4 osteocyte-like cells. Methods Three hours after MLO-Y4 osteocytes were seeded, a continuous compressive force (CCF) of 31 dynes/cm2 with or without additional CCF (32 dynes/cm2) was loaded onto the osteocytes. After 36 h, the additional CCF (loading history) was removed for a recovery period of 10 h. The expression of RANKL, OPG, RANKL/OPG ratio, cell numbers, viability and morphology were time-dependently examined at 0, 3, 6 and 10 h. Then, the same additional CCF was applied again for 1 h to all osteocytes with or without the gap junction inhibitor to examine the expression of RANKL, OPG, the RANKL/OPG ratio and other genes that essential to characterize the phenotype of MLO-Y4 cells. Fluorescence recovery after photobleaching technique was also applied to test the differences of gap-junctional intercellular communications (GJIC) among MLO-Y4 cells. Results The expression of RANKL and OPG by MLO-Y4 osteocytes without a loading history was dramatically decreased and increased, respectively, in response to the 1-h loading of additional weight. However, the expression of RANKL, OPG and the RANKL/OPG ratio were maintained at the same level as in the control group in the MLO-Y4 osteocytes with a loading history but without gap junction inhibitor treatment. Treatment of loading history significantly changed the capacity of GJIC and protein expression of connexin 43 (Cx43) but not the mRNA expression of Cx43. No significant difference was observed in the cell number or viability between the MLO-Y4 osteocyte-like cells with and without a loading history or among different time checkpoints during the recovery period. The cell morphology showed significant changes and was correlated with the expression of OPG, Gja1 and Dmp1 during the recovery period. Conclusion Our findings indicated that the compressive force-induced changes in the RANKL/OPG expression could be habituated within at least 11 h by 36-h CCF exposure. GJIC and cell morphology may play roles in response to loading history in MLO-Y4 osteocyte-like cells

Decrease in Animal Population Sizes in the Bago Mountains, Myanmar

Myanmar is located at the transition zone between the Continental Southeast Asian and Sino-Japanese regions. This plant geographical transition produces unique and diverse species assemblages. However, in recent years, the biodiversity in the region has been rapidly decreasing as a result of deforestation and forest degradation, while, reports on the fauna and flora in Myanmar are still lacking. This study aims to examine the change in animal population sizes around a rural village in the Bago Mountains, central Myanmar. We collected data on the change in animal population sizes over the last 10 years (2006-2016) by an interview survey for two hunters. In addition, we set camera traps in forests around the village. Hunters hunted 23 animal species and camera traps took pictures of five species. Populations of large animals tended to decrease more rapidly than those of small animals. Only the population size of Rattus tanezumi, the smallest animal of the 23 species, increased during the 10-year period. Human activity, in the form of deforestation and forest degradation, may be one of the primary causes of the loss of biodiversity and animals in the Bago Mountains.本研究は環境省地球環境研究総合推進費「途上国での生物多様性と地域社会の相乗便益を目指したセーフガード策定に関する研究（平成26 ～ 28年度、課題番号４－１４０４」、課題代表者　奥田敏統）の一環としてミャンマー国内で実施した
