  • The present study has a dual purpose to investigate the current state of school English library and needs required for its effective use, and to propose a reading program at the school library. The literature on school library was reviewed. A questionnaire survey was done to find out the current situation of English library at the secondary school. The analysis of 26 secondary English teachers' responses reveals that there was the absence of librarians or reading specialists at the school English library. It was also found that the uses of the English library were limited due to the absence of the specialists, no guidelines, and no link between the curriculum and the library use. A case study on a 2-week special reading program at the school English library was conducted and 15 middle school students took part in the project. The participants took pre- and post-tests to identify their reading level using a software and did a variety of reading activities using the books selected according to their level. The comparison of the tests shows that most of the students' reading level improved after the reading program. The analysis of their views on the program and its effects reveals that they gained confidence in reading and their vocabulary understanding was improved. Some suggestions are made for the effective management of the school English library.

  • We examined the effect of polyether-type nonionic surfactants (Brij 35, Triton X-100, Tween 20 and Tween 80) on the potentiometric properties of sodium-, potassium- and calcium-selective membranes which are prepared with widely used ionophores and four kinds of polymer matrices [poly(vinyl chloride) (PVC), polyurethane (PU), PVC/PU blend, and silicone rubber (SR)]. It was found that the PVC-based membranes, which provide the best performance among all other matrix-based membranes in the absence of nonionic surfactants, exhibited larger change in their potentiometric properties when nonionic surfactants are added to the sample solution. On the other hand, the sodium-selective SR-based membrane with calix[4]arene, potassium-selective PVC/PU- or SR-based membrane with valinomycin, and the calcium-selective SR-based membrane with ETH 1001 provide almost identical analytical performance in the presence and absence of Tween 20 or Tween 80 surfactants. The origin of nonionic surfactants effect was also investigated by interpreting the experimental results obtained with various matrices and ionophores. The results suggest that the nonionic surfactant extracted into the membrane phase unselectively form complexes with the primary and interfering ions, resulting in increased background potential and lower binding ability for the ionophore. Such effects should result in deteriorated detection limits, reduced response slopes and lower selectivity for the primary ions.

  • Presented here are policy alternatives for understanding home health care for the long-term health care insurance system which is being developed for elderly people starting 2007. The summary of issues concerning home health nursing care under the long-term care insurance system include; 1) absence of comprehensive and systematic policy in home health care deliverly systems; 2) absence of community based home health agencies that are considered as the community residents in general. In order to overcome these problems and Issues, policy alternatives of home health care should 1) establish a comprehensive home health care policy for homebound persons; 2) establish the foundations for home health care nurses and community based home health care systems; 3) establish home health care facilities and infrastructure; and 4) promote research and development concerning home health care. Conclusively, a home health care system should be built on a comprehensive policy vision based on health policy, especially long-term care insurance system in the near future. Every homebound residents service has to be constructed systematically under suitable facilities considering the consumer characteristics and health conditions. By doing this, the consumer based comprehensive community home health care delivery system can be constructed in view of the long-term health care insurance system for elderly people.

  • Purpose: The study aimed to collect the first aid activity log data of patients who were retransferred through paramedics and to analyze the data in the hospital to improve the plan. Methods: We analyzed 434 retransferred patients, out of the 18,197 patients who visited the emergency medical center in the C area in G metropolitan city, from January 2017 through December 2018. The collected data were analyzed using the SPSS software. Results: The patients were retransferred for various reasons: 17.7% (77 cases) due to the absence of specialists, 15.0% (65 cases) required first aid, and 5.3% (23 cases) due to absence of medical department. In addition, the major medical department with the largest number of retransfer was the department of emergency medicine with 38.2% (166 cases). In the prehospital stage, 38.5% (167 cases) were classified as severe, but in the hospital stage, they were classified as mild. In addition, as a result of hospitalization and discharge, 60.4% (262 cases) were discharged. Conclusion: Most of the retransferred patients were non-emergency patients, and were discharged for mild conditions. The overcrowding in the emergency room of a tertiary hospital can be prevented by reducing the retransmission.

  • We researched 3 patients diagnosed as Lateral epicondylitis (Tennis elbow). We considered it as tendinosis including irregular collagen fiber's pattern. So, acupuncture therapy and musculotendinous releasing manual therapy were used to treat the patients. We measured their pain and functional disorder by visual analogue scale (VAS), Patient-Rated Tennis Elbow Evaluation (PRTEE), and a dynamometer before and after treatment. As a result, VAS and PRTEE significantly reduced and grasping power was also improved. Therefore, we conclude that the acupuncture therapy with musculotendinous releasing manual therapy is an effective way to treat Lateral epicondylitis. But there are limits on this study due to insufficient number of cases, absence of control group and absence of follow-up after last treatment. Further studies will be needed.

  • The exploitation of the natural resources of the Moon and other celestial bodies represents one of the most exiting future developments in the field of space law as well as a unique occasion for the economic and social growth of mankind as a whole. The large number of benefits that are expected to be generated from the exploitation of these resources, indeed, not only will contribute to the betterment of conditions of people on Earth but also will allow mankind to face and likely solve one of the biggest problems currently affecting our planet, namely the exhaustion of the stocks of raw materials and other source of energy, such as fossil fuels. The exploitation of the natural resources of the Moon and other celestial bodies, however, has been prevented so far by the absence of dedicated space law rules allowing its orderly and peaceful development and clarifying the rights and duties of the parties involved in it. Due to the uncertainty generated by the absence of these rules, indeed, States as well as private operators have refrained from investing in the exploitation of space resources so far. The time to change this situation and to allow the exploitation of extraterrestrial resources to begin has finally come. This paper aims at fulfilling this purpose by proposing a legal regime containing specific and detailed rules to regulate the exploitation of the natural resources of the Moon and other celestial bodies.

  • Purpose: This study aims to test the validity and criteria-related reliability of the Korean version of the Copenhagen Psyco-social Questionnaire version II (COPSOQ-K) assessing the psychosocial working environment. Methods: The COPSOQ-K was developed through forward-backward translation techniques, and revision based on feedback from focus groups. Survey data were collected from 311 office workers who worked in one workplace. An internal consistency reliability was estimated by Cronbach's ${\alpha}$. The impacts of the COPSOQ-K scales on job satisfaction, self-rated health, stress, sleeping troubles, burnout, and sickness absence were analyzed with multiple regression model or multiple logistic regression model, adjusted age and gender using SAS version 9.3. The Pearson correlation coefficients between the COPSOQ-K scales and Korean job stress and its subdomain were identified. Results: Cronbach's ${\alpha}$ of COPSOQ-K scales was adequate or good (0.66~0.87). The major COPSOQ-K scales predict job satisfaction, self-rated health, stress, sleeping troubles burnout, and sickness absence. The major COPSOQ-K scales were correlated with Korean job stress and its subdomain. Conclusion: The COPSOQ-K scales have satisfactory reliability and criteria-related validity. The COPSOQ-K scales will be useful for the future studies and practices associated with psychosocial working environment.

  • The tunnel excavations are used for construction of common utility tunnel, electric tunnel, communication line tunnel, water supply and public sewerage pile line in urban area. The trench cut methods were mainly used in the past, but now, tunneling method is more being used. The tunnel excavation method like as NATM, Messer-Shield, Semi-Shield Methods are being applied to small section tunnel in Korea. The actual construction results of seme-shield method are increasing due to simplified construction process and reduced noise and vibration. And also this method is being used frequently in waterway tunnel and construction of prevention flooding recently. The seme-shield method design guideline is absence except for electric line tunnel construction in Korea, because of the semi-shield method was developed in Europe and Japan. In the prescriptive design, engineer's subjects are tending to intervene, because of absence of standard and specification for details. Therefore, Design and Construction Problems of Semi-Shield Method were described and construction trouble was introduced for exam. These problem and construction troubles have to be examined thoroughly in advance.

  • This research is a case study that focuses on how conglomerate illegality and corresponding penalty affects corporate performance and strategy. The research aims to provide base information for policy-makers as well as the general public about the corporate environment. The analysis results can be summarized as follows. First, profitability is represented as an M-curve. Profitability falls from indictment to the final pronouncement of the corporate head and increases upon his or her return. The result suggests that the absence of a corporate head could result in low profitability as the firm is exposed to owner risk. Secondly, significant effects on investment were not found. Investment showed a continuous increase from indictment to final judgment. This could have resulted from investment decisions made prior to the indictment, which are generally long-term. Meanwhile, the rate at which investments rose for core subsidiaries were lower, which makes it reasonable to suspect dwindling executive capacity due to the absence of a corporate head. Thirdly, employment showed a slight increase, but the rate was found to be greater during the periods following the final judgment. From a political perspective, this increase can be inferred from a give-and-take tradeoff between corporate employment and the pardon of the corporate head.

  • The Jun activation-domain binding protein 1 (Jab1) induces p53 nuclear export and cytoplasmic degradation, but the underlying mechanism is poorly understood. Here, we show that phosphorylation at the threonine 155 residue is essential for Jab1-mediated p53 nuclear export. Jab1 stimulated phosphorylation of p53 at T155 was inhibited by curcumin, an inhibitor of COP9 signalosome (CSN)-associated kinases. The T155E mutant, which mimics phosphorylated p53, exhibited spontaneous cytoplasmic localization in the absence of Jab1. This process was prevented by leptinomycin B (LMB), but not by curcumin. The substitution of threonine 155 for valine (T155V) abrogated Jab1-mediated p53 nuclear export, indicating that phosphorylation at this site is essential for Jab1-mediated regulation of p53. Although T155E can be localized in the cytoplasm in the absence of Mdm2, the translocation of T155E was significantly enhanced by ectopic Hdm2 expression. Our data suggests that Jab1-mediated phosphorylation of p53 at Thr155 residue mediates nuclear export of p53.
