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.

본 연구는 경상북도를 사례로 귀농 귀촌의 유형별 정착 및 적응실태를 분석하고, 이에 기초하여 정책적 함의를 제시하고자 한다. 경상북도 귀농 귀촌인(가구)의 속성은 시 공간적으로 차별성을 가질 뿐만 아니라 이들의 정착 및 적응 실태는 그 유형에 따라 상이한 것으로 밝혀졌다. U턴은 영농과 농촌공동체생활의 경험을 가진 이촌향도 1세대가 주류로, 상대적으로 경종에 종사하는 비중이 크다. J턴과 I턴은 귀농 초기 영농기술과 농촌생활에 대한 경험이 없고 전원생활의 향유가 주된 동기로 상대적으로 저소득층의 비율이 높다. U턴은 상대적으로 타 유형에 비해 적응과정에 있어서의 만족도가 낮고 그 과정의 문제점은 주로 가족 및 공동체 자산을 통해서 해결하고 있다. I턴과 J턴은 정착에 대한 만족도는 상대적으로 높지만 준비부족으로 많은 어려움을 겪고 있었다. 정책적 함의로는 일반적이고 포괄적 지원정책의 탈피, 귀농 귀촌의 지역 및 유형별 속성에 '뿌리내려진 정책(embedded policies)'으로의 전환, 귀농 귀촌정책 거버넌스 체제의 개선, 이주 전 준비과정에 대한 지원 및 유형별 맞춤형 지원의 강화 그리고 귀농 귀촌가구와 기존 주민의 정주기반의 통합적 개선을 제시하고자 한다.

Polystyrene is frequently used for food packaging because of its eaxy processing rigidity , and low cost. Styrene, which is present in detectable amouts in the polymer, is usually considered to be the substance responsible for the possible tainting of a polystyrene-packed food by migration. The contamination of foods and beverages by trace amounts of materials which have migrated from plastics use din packaging is a concern both on the grounds of adversely affecting product quality and of food safety. These lead to increasing attention to the potentional hazards of a large variety of plastic materials and foods. In this paper we reviewed the history of Styrene and various analytical methods of sample preparation and detection to assess the extent to which styrene is present in food-grade polystrene materials and to what extent it leaked into foods and food stimulants.

We attempted to reconstruct basement membrane (BM) in between the epidermal compartment and dermal compartment in the artificial skin preparation and examine its effect on the skin architecture as well as on the epidermal differentiation. Laminin, one of the component of BM, stimulate the migration of the basal cells but type IV collagen which is a major component of the mechanical network of BM did not stimulate epidermal migration. However laminin in the presence of type IV collagen at a 1:1 molar ratio did not stimulate epidermal migration but provide nice demarcation between epidermis and dermis. This mixture of laminin and type IV collagen enhanced epidermal differentiation in the artificial skin based on the morphological observation as well as biochemical criteria. The epidermal acquirement of migratory ability on the laminin-rich substrate suggest that this type of unbalance in the expression of the components of BM may prevail in the area of healing tissue and the invasive transition of the tumor. The result in this study provide the technical improvement in the artificial skin preparation and further application of this technique for the reconstruction of other bio-artificial organ.

This research investigated the retired elderly who had moved to rural areas. The propose of the study was to examine the point at which there must be a difference in the patterns of a return to farming and determine the actual condition of their preparations for migration. This study had surveyed 408 seniors who wereare over 50 years old and had moved to rural areas after their retirement and analyzed the data by the SPSS PC 11.0 program. The results were as follows. First, the relevancy of U-turn, J-turn, and I-turn types that were affected by social demography was found to be dependent on their education levels and family patterns. Second, the actual conditions of the process of preparation by the types of a return to the farming were different according to the motivation and preparation fund. Nevertheless, the most important factor was the influence of their spouses. Third, the actual conditions of the process of adaptation by the patterns of a return to the farming showed no difference between the degree of efforts of the social supportand elevation of the friendship among the neighbors. The recognition of rural life problems were more acquainted towards the area of farming life. Among the 6 problem areas, leisure, health care, and economic problems were highly considered.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been accepted as an adjunct procedure for non-compressible torso hemorrhage in patients with hemorrhagic shock. With appropriate indications, REBOA should be performed for resuscitation regardless of the physician's specialty. Despite its effectiveness in traumatized patients with hemorrhagic shock, performing REBOA has been challenging due to physicians' lack of experience. Even though training in endovascular skills is mandatory, many physicians cannot undergo sufficient training because of the limited number of endovascular simulation programs. Herein, we share simulation video clips, including those of a vascular circuit model for simulation; sheath preparation; long guidewire and balloon catheter preparation; ultrasound-guided arterial access; sheath insertion or upsizing; and balloon positioning, inflation, and migration. The aim of this study was to provide educational video clips to improve physicians' endovascular skills for REBOA.

A simple assay method of recombinant human epidermal growth factor (rhEGF) in a pharmaceutical preparation was studied and validated by capillary electrophoresis (CE) using micellar electrokinetic chromatography (MEKC) techniques. Factors affecting the migration behavior and separation performances of the peptide; type of buffers pH, butler concentration, and concentration of sodium dodecyl sulfates (SDS) were investigated to optimize the analytical performance. CE was performed using running buffers 50.0 mM borate (pH 8.5) containing 12.5 mM SDS at 20 $mutextrm{V}$ of the applied voltage. Calibration curves for the rhEGF showed good linearity (r>0.999) over the wide dynamic range from 1.25 to $100{\mu\textrm{g}}/ml$. Sample analysis was performed by using standard addition method to eliminate the matrix effects of dosage vehicle. This method is assumed to be useful for quality control (QC) of various forms of pharmaceutical products of the peptide.

In order to study about the lobule and layer formation and cell migration of the mouse cerebellum from at the birth to 15th day effected by 2.5, 5 and 10 Gy r-raddiation at the 19th pregnancy. The routine tissue preparation and staining procedure, Immunohistochemical staining method by the several antibody and western brotting method were utilized from the birth to the15th day. The results were as followings. 1. The body and cerebellum weights were more slowly increase of the the 2.5 Gy, 5 Gy and 10 Gy irradiation group compare to the control group, and the health condition of the 2.5 Gy group was a little bad. but the 10 Gy group was more severe and begun to die from the 12th day after birth. 2. The thickness, proliferation and migration of the 2.5, 5 and 10 Gy irradiated external granular cells from the maginal zone to the medullary area forming the molecular layer from the 6th day to the 15th day after birth were thinner, weaker and more slower according to the radiated dosages than the control group in the cresyl violet staining. 3. The proliteration, migration and lobulation of the 5 Gy radiated groups from the first day to the 15th day after birth were more weak, incomplete and irregular shape in the immunostaining with Dab, Cdk5, P35, calbindin and Zebrin antibody. 4. In the western blotting analysis using the Reelin, Dab, Cdk5 and P35 antibody. The Bands were in the 60 KD, 80 KD, 33 KD and 35 KD, and there were no differences between the control and irradiated groups in the molecular band except the Reelin. 5. As a results, the proliferation and migration of the outer granular and purkinje cells, and lobulation of the cerebellum by the several dosaege of the ${\gamma}$-ray radiation were proportionally incomplete according to dosage.

Polyclonal antibody of the boar sperminogen was used to characterize the boar sperm proteinase sperminogen. Boar sperminogen was purified from the acid extracts of the washed epididymal spermatozoa by gel filtration through a Sephadex G-100 column. followed by preparative SDS-PAGE. The sperminogen band was sliced out and was eluted from the gel matrix. The purified sperminogen was used to produce the polyclonal antibody of the boar sperminogen. When characterized on a Western blot, the final preparation of sperminogen appeared as a homogenous protein with a molecular weight of 32 kDa. The relative migration of sperminogen was distinctly different from the major components of the proacrosin-acrosin system as well as all the observable proacrosin activation by-products detected on the Western blot. The sperminogen antibody, however. cross-reacted with the proacrosin-acrosin system.
