Objective: The aim of this study is to review the studies on job rotation with various points of view and to classify the studies considering the approach methods. Background: Various work interventions were carried in order to prevent the work-related musculoskeletal disorders(WMSDs) and job rotation was considered as one of the simple and effective methods. Method: Previous studies were systematically collected with the combination of keywords such as job, task, rotation, allocation, line balancing, etc. Collected studies were classified into three categories: field study, laboratory study and optimization approach study. Results: Field studies showed that most studies focused on the evaluation of the factors causing the musculoskeletal disorder. Moreover, the effect of job rotation could be hard to identify because it required a long-period close observation. Laboratory studies covered only simple aspects of tasks or movements. Optimization approach studies showed the systematic approach to establish the job rotation scheme though many limitation and assumptions were adopted. Conclusion: This study collected and classified the previous studies on job rotation and presented the different approaches across various research areas. Application: The results of this study could help the practitioner and ergonomist how to establish the job rotation scheme.

The first part of this study reviewed the characteristics of calcium hydroxide ($Ca(OH)_2$) and summarized the results of in vitro studies related to its antimicrobial effects. The second part of this review covers in vivo studies including human clinical studies and animal studies. The use of $Ca(OH)_2$ as an intracanal medicament represented better histological results in animal studies. However, human clinical studies showed limited antimicrobial effects that microorganisms were reduced but not eliminated through the treatment, and that some species had resistance to $Ca(OH)_2$. Most of clinical outcome studies supported that there is no improvement in healing of periapical lesions when $Ca(OH)_2$ was applied between appointments. Further studies are required for the antimicrobial effects of $Ca(OH)_2$, and search for the ideal material and technique to completely clean infected root canals should be continued.

Objectives: This study was performed to review the research trends in the treatment of eating disorder in traditional Chinese medicine (TCM). Methods: The CNKI database (China National Knowledge Infrastructure) was searched under the key words ‘Eating Disorder’, ‘Anorexia Nervosa’, and ‘Bulimia Nervosa’. Results: Thirteen articles were selected. These included 2 studies on bulimia nervosa, and 11 studies on anorexia nervosa. According to study design, studies were classified into 1 randomized controlled trial, 2 single group before-and-after studies, and 8 case reports. According to therapy method, they included 11 herbal medicine studies, and 2 complex treatment studies. The most common pattern identification was ‘liver qi depression’ (肝氣鬱結), and the most used herb was ‘Root of Bupleurum falcatum’ (柴胡). Most of the studies showed effective results. Conclusions: The results of our study indicated that TCM clinical studies on eating disorder were being conducted more actively than in Korean medicine. Korean medical treatment might be effective to relieve eating disorder symptoms. In the future, more scientifically designed clinical studies should be performed to prove the effectiveness of traditional Korean medicine treatment on eating disorder.

This paper interrogates the theoretical foundations of Cross-Cultural Studies across the Social Sciences through an examination of the field ELT. Through an examination of ELT's major theoretical and pedagogical moves, this paper illustrates how ELT is by nature a field of cross-Cultural Studies. A closer examination of the history of ELT shows how the colonial genesis of the field indicates a skewed representation of power between native English speaking nations and non-native speaking nations both in terms of academic theories and pedagogies, as well as socio-cultural relations of power. A further analysis of how the field theorizes and represents various relations of power between disparate cultures in ELT literature explicates the dilemma of the objectivity and neutrality of Cross-Cultural research in ELT. In doing so, the analyses included in this paper thus necessarily raises questions regarding the theoretical foundations of research methodologies of Cross-Cultural Studies in terms of the reflexivity of researchers and the problematic of how, or if, relations of power are included in the studies. This paper questions whether studies that do not include these research perspectives properly represent the disparate cultures under study, or are more of a biased, or Orientalized (Said, 1979) interpretation of cultures.

Diaspora studies has become one of the fastest growing field in the humanities over the past several decades, and the use of term diaspora has been widening to include almost any population on the move. Diaspora literature not only mirrors but actively incorporates this new notion of diaspora with characters "at the threshold" navigating new territories and identities. Querying how diaspora studies intersects with theatre and performance, this paper attempts to probe how recent Korean American drama parallels and promotes diaspora studies' radical departure from traditional notions of identities and territories. For this purpose, this essay 1) examines theoretical affinities between diaspora studies and performance studies 2) investigates how Sung Rno's plays, Cleveland Raining and wAve, explore and embody multiple and evolving meanings of Korean diaspora on the stage 3) examines how theatre can create the third space that transcends both Korean and American nationalism and 4) speculates possibilities of reframing Asian American Studies as Asian diaspora studies. Korean American characters in Rno's play redirect diasporic identities, as their concern gradually moves from "where I come from" to "where I go to." Instead of remaining in the dark as a mere spectator, both Rno and his characters choose to be 'on' the stage where they can imagine, perform, and realize (however temporarily) "unimaginable community" by confronting their own social, political, and cultural ambivalence. Stage, the threshold between reality and fiction, Korea and America, and past and future, becomes their true 'home' where they incubate and precipitate "nation in transformation" that Yan Haiping argues for as "another transnational."

The methanolic extracts of the leaves and stem of the plant Lepidagathis keralensis were evaluated for anticorrosion behavior against mild steel in 1M HCl. Corrosion inhibition studies were done by gravimetric method, electrochemical impedance spectroscopy and potentiodynamic polarization methods. Surface morphology of mild steel in the presence and absence of inhibitors were studied using SEM analysis. UV-Vis studies were also done to evaluate the mechanism of inhibition. Both the extracts showed good inhibition efficiency which increased with increase in concentration of the inhibitor and decreased with increase in temperature. The mechanism of inhibition was explained by adsorption which obeyed Langmuir adsorption isotherm. Thermodynamic calculations revealed a combination of both physisorption and chemisorption of the inhibitor on the surface of mild steel. The extracts behaved as mixed type inhibitors as determined by polarization studies. Quantum chemical studies on Phenoxyethene, one of the major components in the leaf extract of the plant was also carried out to support the experimental results.

Postherpetic neuralgia(PHN) is one of the most common intractable chronic pain syndromes. This review was conducted to investigates the trends in recent clinical studies of PHN in China and to find out the efficacy of Chinese medicine treatment for PHN. Based on CNKI databases, nineteen randomized controlled trials(RCTs) were analyzed. The search focused on the authors, publication year, sample size, age, duration of illness, treatment period, lesion sites, methods, outcome measures, and results of the selected articles. Four studies used herbal medicine. The most frequently used herbs were Angelicae Gigantis Radix(當歸) and Corydalis Tube(玄胡索). Eighteen studies used acupuncture treatment. The most frequently used acupoints were ST36, LR3, LI4. Three studies used moxibustion and 5 studies used cupping treatment. In all nineteen studies, the efficacy of Chinese medicine treatments was confirmed. More varied and scientifically designed clinical studies are required to develop treatments for PHN. The results of current study could be used as guidance for further studies of treatment on PHN.

Endophytic fungi occupy inner plant tissues, which results in various interactions between the fungus and host. Studies on endophytic fungi have been conducted in Korea for over 30 years. This paper summarizes the published results of those studies. The endophytic fungi of approximately 132 plant species in Korea have been studied since the 1990s, resulting in over 118 publications. The host plants featured in these studies comprised 3 species of mosses, 34 species of woody plants, and 95 species of herbaceous plants. At the family level, the most studied plants were members of the Poaceae family, covering 18 species. Regionally, these studies were conducted throughout Korea, but over half of the studies were conducted in Gyeongsangbuk-do, Gangwon-do, and Chungcheongnam-do. Relatively few studies have been conducted in a metropolis such as Seoul. We confirmed 5 phyla, 16 classes, 49 orders, 135 families, 305 genera, and 855 taxa of endophytic fungi, excluding Incertae sedis, whose relationship with others are unknown. Most of the endophytic fungi belonged to Ascomycota (93.2%), and a few belonged to Basidiomycota (3.6%). Since the diversity of endophytic fungi differs depending on the host plant, plant tissue, and distribution region, future studies should be conducted on multiple host plants and in various regions. Future studies on endophytic fungi are expected to broaden, including genomics and taxonomic and ecological studies of secondary metabolites.

The purpose of this study was to use meta-analysis to analyze result of 17 studies which investigated the effects of integrated programs, and 11 studies which examined the effects of exercise programs on pain, depression, and disability. The 28 studies analyzed in this work were selected from the following sources. MEDLINE Search, bibliographies of related studies, main academic journals of nursing in Korea, and journals on arthritis issues. For the analysis of the data, homogeniety of effect sizes which were calculated based on data in the 28 studies was tested and its average effect size was computed by using meta analysis software package which was developed by Song(1992, 1998). The results can be summarized as follows : 1) Homogeneity tests were conducted on integrated programs on pain. In the prelimiary homogeneity tests on effect size of all 17 studies, no homogeneity was found. When homogeneity tests on the effect size of the remaining 15 studies were performed, excluding two studies which had extremely larger effect size compared to other studies, the 15 studies were found to be homogeneous(Q=16.38, p=.23). The obtained average effect size, D(Mean Standardized Difference Between Means), was .25. When homogeneity tests on effect size on pain was conducted for the excercise programs, effect size for all nine studies were found to be homogeneous (Q=7.42, p=.49) and the average effect size D=.30. Therefore, Hypothesis 1 was rejected from the results, that an average effect size of the integrated programs on pain was not significantely different from that of the exercise programs on pain. 2) Since only two studies investigated the effect of exercise programs on depression, comparison between the average effect size of integrated programs and that of exercise programs on depression could not be conducted, and hypothesis 2 could not be tested. Thereby, only the average effect size of integrated programs on depression was obtained. Eight studies were tested to be positive on the homogeneity of effect sizes(Q=18.31, p=.02) at $\alpha$<.01 and its average effect size was D=.11. 3) For the analysis of integrated program on disability, 13 studies, except for four which had an extremely large effect size compared to the others were found to be homogeneous at $\alpha$<.01 (Q=22.30, p=.04) and the average effect size on disability was D=.16. For analysis of the exercize programs on disability, eight studies, except for one which had an extremely large effect size compared to others, were found to be homo geneous(Q=7.87, p=.34) and the average effect size on disability was D=.60. Therefore, Hypothesis 3 was accepted from the results that an average effect size of exercise programs on disability was significantly larger than that of integrated programs on disability.

본 연구는 국내 외 노인 대상 음악 활용 연구 내 음악 적용 방법을 고찰하는 것을 목적으로 하였다. 전자 데이터베이스 검색 및 수기 검색을 통해 선정 기준에 부합한 국내 연구 19편, 국외 연구 21편의 총 40편이 선정되었다. 분석 결과, 국내외에서 노인을 대상으로 한 음악 활용(중재) 연구 시작 시기가 1990년대 말로 유사하며 게재 논문 수 역시 지속적으로 증가하는 것으로 나타났다. 국내외 문헌 모두에서 노인의 정서, 특히 우울에 개입한 음악 활용 연구가 가장 많은 비중을 차지했고, 음악 적용 방법에 있어 국내에서는 민요와 대중가요를 활용한 가창 활동, 국외에서는 클래식 및 명상음악의 감상이 주요한 활동으로 적용된 것으로 나타났다. 또한 국내외 연구 모두 기존 음악의 사용이 두드러졌으며, 국내 연구에서는 라이브 음악의 사용 비중이 국외 연구에 비해 높고 대상자의 선호가 반영된 음악을 선정하는 경향이 높은 것으로 나타났다. 이러한 결과는 노인 인구 증가와 함께 성공적 노화에 대한 노인 대상군의 높은 요구가 국내외 연구에서 성공적으로 반영되고 있음을 보여주는 반면, 구체적으로 음악을 적용하는 데 있어 문화적 요인으로 인해 국내외 연구에 서로 차이가 있음을 시사한다. 이러한 결과를 바탕으로 추후 문화적, 사회적 요구가 반영된 다차원적인 접근의 활용연구가 지속적으로 필요함을 제안하였다.
