Purpose: The purpose of this study was to identify the factors influencing intention of migration by Korean hospital nurses. Methods: Using cross sectional correlational design, data were collected from 512 nurses working in 7 hospitals ranging in size from 300 to 900 beds in D city and K province of Korea. Data were analyzed by descriptive statistics, chi-square, and multiple hierarchical regression using the SPSS program. Results: There were significant differences in intention of migration by age, educational background, marital status, work experience, and yearly incomes. Although there was high intention of migration of the subjects, the level of preparation for migration was relatively low. The variables that were independently associated with intention of migration were graduates of RN-BSN program, personal factors of subjects, and environmental factors. Those who had lower perception on nursing images and work condition had significantly higher intention of migration than those who had higher perception. Full model accounted for 37.3% of the variance in intention of migration. Conclusion: To prevent brain drain of competent nurses in Korea, appropriate strategies to enhance work condition should be developed and the effect of migration of nurses should be investigated in further studies.

Now-a-days, data and task migration in collaborative work provides enormous facilities to users. Here, we propose an ontology-based information management scheme to facilitate data and task migration in collaborative work. This ontologybased model will help us to organize huge information (e.g. device status, runtime state etc.) efficiently.

최근 정부 및 교육기관 차원의 해외취업/인턴십 프로그램이 증가하면서 싱가포르의 저숙련 저임금 서비스 직종에서 일하는 한인 청년들이 늘어나고 있다. 본 연구는 이처럼 싱가포르 내 새로운 유형의 한인 이주자로 등장하고 있는 이 청년들과 싱가포르, 한국에서 진행한 심층면접조사를 바탕으로, 이들의 해외 취업 동기와 기대, 취업 이주 경로, 싱가포르에서의 일 경험, 귀국 후 생활을 살펴본다. 싱가포르 해외취업 경험이 있는 청년 중 다수는 싱가포르 취업 사증 중 가장 낮은 등급의 저숙련 사증인 WP(Work Permit)를 소지하고 서비스직에서 근무하며 탈숙련화를 경험하고 있다. 본 논문은 이들이 취업 이주를 통해 자신들의 기대와 목표를 충족하고 있는지, 아니라면 어떻게 대응하며, 자신의 이주 경험을 어떻게 해석하고 있는지 살펴보고자 한다. 최근 증가하고 있는 청년단기 해외취업 현상에 대해 만족도 효용 평가, 프로그램 정책 평가 및 제언 등을 담은 연구들이 발표되고 있다. 그러나 이를 이주 연구(migration studies)의 맥락에서 살펴보고, 청년들의 구체적인 경험들과 그에 대한 본인들의 해석에 집중하는 연구는 드물다. 본 연구는 이들의 경험을 면밀히 살피고, 이를 탈숙련화와 이동성 자본(mobility capital) 개념을 통해 해석해 봄으로써, 청년 해외취업의 구조적인 문제를 드러냄과 동시에 이들의 행위자성에 주목한다.

현재 기업들은 많은 업무들을 효율적이고 체계적으로 활용하기 위해 다양한 시스템으로 구축해 왔다. 그러나 급속한 IT의 발전으로 각 업무들이 각기 다른 시스템 환경으로 구축되어 많은 유지보수 비용이 지출되어지고 있는 현황이다. 이에 최근 들어 많은 기업들이 IT유지보수 비용을 절약하기 위해 시스템 통합 또는 다운사이징 마이그레이션을 필요로 하지만, 현재 대부분의 기업들은 마이그레이션을 수작업으로 새롭게 시스템을 구축 하거나 일부 변경하는 작업을 진행하여, 마이그레이션 또한 많은 비용을 필요로 하게 되고 있다. 본 논문에서는 시스템 환경 구성요소 중 애플리케이션을 중심으로, 마이그레이션 비용을 줄이기 위한 애플리케이션 재활용 및 자동화 도구 활용 방안을 제시한다.

Intramolecular energy migration in a cyclic porphyrin array is spontaneous transfer of energy from one excited site to another. Since the efficiency of energy migration is inversely proportional to distance, the energy migration is occurred on their adjacent sites more often than distant ones. Therefore, the energy migration in the cyclic porphyrin array is largely dependent on their conformational characters. However, evaluation of conformational information by means of experimental tools is ambiguous since their limited resolution. In this work, we calculate the internal angle and distance distributions of cyclic porphyrin arrays using molecular dynamics simulations to obtain conformational information. To evaluate the angle and distance distributions respect to molecular size, we constructed molecules with n porphyrin dimers (n=1,3,7) in implicit solvent environment. Performing molecular dynamics simulations, we modulated alkyl groups to investigate additional conformational effects of the system.

The paper explores the return migration choice of graduates, which takes place during the transition from higher education to the labor market. Graduate students, after a short time in temporary migration to cities for studying, have to make a decision of returning back home or staying in migration in urban areas for working. Drawing on the mechanism identified in the literature on internal migration, this empirical research tests the effects of two factors: place attractiveness and social supports factors on graduates' decision to return migration to hometown. A binary logit regression analysis was conducted with data from 502 surveyed graduates in Hanoi, Vietnam. The analysis of the motives reported by graduates indicates that return migration decisions cannot be reduced to a single dimension. Perceived attractiveness of a region such as quality of living environment, job opportunities, and social context of individuals positively impact on student' decision to return migration after graduation. The research results imply that, in a collectivistic country like Vietnam, students' choice of future career is strongly influenced by their social context, and choosing a place to work is not simply a matter of earning a higher salary or enjoying better working conditions, but is also related to family issues.

Purpose: The purpose of this study was to analyze the migration patterns of new nurses and experienced nurses and to identify the factors influencing inter-regional migration for solving regional imbalances of clinical nurses in South Korea. Methods: This study involved a secondary analysis of data from the Health Insurance Review and Assessment Service (HIRA). Data were analyzed using descriptive statistics and multiple logistic regression analysis. Results: New nurses tended to migrate from Kyunggi to Seoul. However, experienced nurses tended to migrate from Seoul and Chungchung to Kyunggi. Significant predictors of inter-regional migration among new nurses were location and nurse staffing grade of hospitals. Significant predictors of inter-regional migration among experienced nurses were location, hospital type, nurse staffing grade, ownership of hospitals and age of nurses. Conclusion: Inter-regional migration occupied a small portion of total hospital movement among clinical nurses. The regional imbalances of nurses were not caused by the migration from non-metropolitan areas to Seoul. Nurse shortage problems in the small and medium hospitals of the non-metropolitan area can be solved only through improvement of work environment.

Increasing use of plastics in food packaging materials has led to the issue of food-plastic packaging materials's mutual interactions. Although the plastic packaging materials are generally considered as inert, migration and sorption of fatty materials are some of the problems associated with their use. So, this work investigated the compatibility of three structurally different polymers, polypropylene (PP), polyethyleneterephthalate (PET) and ethylene vinyl alcohol copolymer (EVOH) with some structurally different food fats. The main goal was to study the sorption of food fats by the plastic films and to see what extent mechanical properties of the plastic films was affected by plasticization effect due to sorption of fatty materials. PP, PET, and EVOH films was immersed in pure triglycerides, and then extracted with hexane and analyzed for the amounts of fat migrated. The sorbed films were also investigated for change in mechanical properties. Result showed that structural factor of the films and fatty materials plays important role in th migration process. The fat with the simplest structure are migrated more easily that the fat with more complex structure. However, structural effect of migration was varied according to degree of crystallinity and density of plastic films. In addition to that, polarity of plastic film was affected migration of fatty materials significantly. Additional research is needed to justify the reason why migration of fatty materials into the films was affected by polarity and structural integrity.

Electrochemical migration phenomenon is correlated with ionization of anode electrode, and ionization of anode metal has similar mechanism with corrosion phenomenon. In this work, in-situ water drop test and evaluation of corrosion characteristics for SnPb solder alloys in $Na_2SO_4$ solutions were carried out to understand the fundamental electrochemical migration characteristics and to correlate each other. It was revealed that electrochemical migration behavior of SnPb solder alloys was closely related to the corrosion characteristics, and Sn Ivas primarily ionized in ${SO_4}{^2-}$ solutions. The quality of passive film formed at film surface seems to be critical not only for corrosion resistance but also for electrochemical migration resistance of solder alloys.
