The purpose of this study is to develop clothing shopping orientation[CSO] scale reflecting the conceptual structure of CSO. For this purpose, a questionnaire composed of comprehensive 85 CSO items was developed through 2-step preliminary tests. Data was collected from two samples. One sample(n=559) was for scale development and the other sample(n=235) was for cross validity test. Descriptive analysis, correlation analysis, exploratory factor analysis, regression analysis, ANOVA, and confirmatory factor analysis were used for data analysis. For each lower-dimension within the CSO conceptual structure model, 1-2 items were selected based on the quantitative and the qualitative standards. As a result, a CSO scale composed of 31 items was developed, and reliability, construct validity, cross validity, convergent validity, discriminant validity, and criterion validity of the scale were verified. This study has significance in offering the standardized scale to both the academic and the practical fields.

The purpose of this study was to identify the psychometric properties of the vocational ability scale used in the 8th Panel Survey of Employment for the Disabled in Korea by using the Rasch model. The sample data was collected from 398 individuals with intellectual disabilities. Item fitness, item difficulty, the appropriateness of the rating scale, and the separation index of the vocational ability scale were evaluated. All 15 items show an appropriate fitness level. The analysis of item difficulty indicate that modifications are required. Specifically, the need for the addition of less difficult question items is identified. The use of a 5-point rating scale is shown to decrease the test difficulty in terms of clarity and readability when appropriate and a 4-point modification is also determined as appropriate. With respect to the outcomes of the analysis, the person separation reliability value and separation index are high, and the reliability of the items is also high.

The present study was carried out to investigate the food and feeding habits of Oreochromis niloticus in Lake Shala to manage this species in this high Soda Lake. Stomachs of 226 fish (65.9%) had different food items, while those of 117 fish (34.1%) were empty. Phytoplankton was the dominant food categories occurring in 90.3% of the stomachs estimated and contributed 75.5% of the total volume. Bacillariophyceae (Nitzschia, Anomoeoneis, Navicula and Melosira) were identified as the most desired phytoplankton item. The prey items of O. niloticus differed among size classes (ANOVA, p < 0.05). The main prey items were zooplankton by the smaller-size class, and phytoplankton in fish of the larger-size class. Seasonal variation in the diet composition was evident (t-test, p < 0.05) and zooplankton, chironomids, nematodes, fish scales and detritus were important during the wet season, while phytoplankton predominates during the dry season. This study concludes that O. niloticus had a phytoplanktivores feeding mainly on phytoplankton and their feeding habits influenced by season and fish size in Lake Shala.

With the opening of healthcare market, the health care environment in Korea is anticipating a drastic change. In this Internationally open market environment, it is necessary to introduce a systematic health care plan and DRG system which offer qualitative medical services as well as reduced cost. Purpose of this study is to develop and test the critical pathway for Cesarean section patient in the way to be possible the integrated inpatient management. It was adopted the process of six phases to develop the critical pathway as the theoretical framework implemented by Johns Hopkins Hospital, Maryland, U.S.A. In the first phase, make a selection of diagnosis/procedures to develop. In the second phase, organize a development team consisted of eight expertises working in maternity nursing area. In the third phase, analyze the overall medical service offered to patient through review medical records and decided the service content and the implementation period for the Cesarean section patient. In the forth phase, make out a preliminary critical pathway after verification of expert group on content validity. In the fifth phase, validity operate to ten Cesarean section patients to test implementation in practice by using the preliminary critical pathway, In the sixth phase, defined the final critical pathway. The result of this study was as follows. 1. There were classified 8 categories as monitoring/assesment, treatment, medication, activity, diet, test, consult, education/discharge plan for vertical axis and showed hospital stayed from admission to discharge for horizontal axis of critical pathway through analysis 68 Cesarean section patients medical records. 2. After critical review 68 medical records to make out a preliminary critical pathway, hospital stays for horizontal axis were showed 6 days, mean hospital stays were 7.5 days, 2.1 days were to be taken operation after admission and 4.2 days were stayed until discharge after operation. 3. After making out a questionare in 90 items of a medical service content of eight categories and verifying the content validity of expertises, the 85 items of the preliminary critical pathway were selected by expertises agreement over 88% and modified or deleted 5 items showing agreement below 75%. 4. After verifying a validity to 10 patients for 4 weeks, hospital stays were 5.9 days. There were deleted 1 item and modified or supplemented the 9 items of the 10 items.

음악치료에서 사정평가는 내담자의 현재 기능과 필요를 파악하기 위하여 반드시 선행되어야 하는 과정이다. 음악치료사는 사정평가의 내용을 바탕으로 치료목적 및 목표를 설정하고 이를 달성하기 위한 단계적 접근과 치료전략을 수립한다. 하지만 기존의 음악치료 사정도구는 해당 영역의 행동을 열거하고 이를 관찰하여 수치화함으로써 기능을 평가하였기 때문에, 실제 인간의 음악행동을 통한 기능의 사정이 불가능하다는 단점을 지니고 있다. 또한 음악행동을 바탕으로 하는 소수의 음악치료 사정도구에서도 음악행동을 구성하는 세부기능영역, 발달단계에 따른 근거에 따른 난이도 검증 과정을 거치지 않고 사용되어 왔다. 본 연구에서는 인지기술 사정을 위한 리듬요소군을 중심으로 한 음악 프로토콜 문항을 개발하였으며 발달학적 근거와 인지기술 수준에 따른 난이도 요소를 규명하고자 하였다. 인지발달에 따른 소리정보의 그룹핑, 구조형식의 수준, 전체-부분 관계의 명료성, 반복-변동성 수준을 고려한 리듬 연주 항목과 연주행동에 내포된 정서 행동을 분석할 수 있는 리듬 사정 프로토콜을 개발하였다. 검증과정으로는 먼저 15개의 예비 리듬문항을 난이도, 복합성, 패턴 유형을 고려하여 선정한 후 이를 일반인 61명을 대상으로 난이도 검증을 실시하여 문항별 수준과 난이도 계수를 도출하였다. 둘째, 7인의 전문가 평가팀의 검증을 통해 1차 개발된 문항들을 수정 보완하여 최종적으로 20개의 리듬프로토콜 문항을 개발하였다. 본 연구의 결과는 이후 개발될 음악치료사정평가도구의 기초 자료로 활용될 수 있다.

A maternity ward in a hospital in Seoul has an educational program for postpartal mothers since its opening, but evaluation on the program has not been done. This study was to find whether the educational program contributed to increase of knowledge and confidence of the post-partal mothers in the area of postpartal self-care and the newborn baby care or not. This study aimed at improvement of the educational program for posrpartal mothers and the newborn babies. Subjects were 40 primiparae who were admitted to the obstetric ward in a general hospitals in Seoul from August 20th to September 10th, 1995. Subjects were those who had no labor pain at the admission time, had no complications during labor and delivery, gave a birth to a healthy baby, and agreed to participate in this study. All subjects were well educated and were in well-to-do group. Most of them received antenatal care adequately. They were tested on knowledge and self-confidence in the area of postpartal self-care and infant care two times, one at the admission time and the other prior to discharge. After the first test, nurses in a maternity ward and nursery taught them on postpartal self-care and infant care. Education consisted of a 1 hour planned program and incident teachings done at bed side. Four tools were developed by authors based literature review. The test tool for knowledge of postpartal self-care consisted of 15 items which included the definition of postpartum, dangerous symptoms in postpartum, lochia, time to begin coitus, postpartum exercise, sitz-bath, and perineal care. The test tool for self-confidence in postpartal self-care included such items as emergency care on dangerous symptoms in postpartum, sexual life and contraception after postpartum, self-confidence in postpartum exercise and perineal care. The test tool for knowledge of newborn baby care consisted of 18 items which included bathing, umbilical cord care, vaccination, breast feeding, abnormal symptoms of neonate. The test tool for self confidence in the newborn baby care included umbilical cord care, vaccination, breast feeding, emergency care for baby. Analysis of demographic data were analyzed with calculation of percentage. Score differences between the first test and the second test were analyzed with paired t-test. SAS / PC (Release 6.04 for DOS) program are as follows. 1. Mothers' knowledge of postpartal self-care increased significantly after education (t=10.04, df=38, p=0.0001). 2. Mothers' self-confidence in postpartal self-care increased significantly after education (t=6.53, df=38, p=0.0001). 3. Mother's knowledge of the newborn abay care increased significantly after education (t=9.74, df=38, p=0.0001). 4. Mothers' self-confidence in the newborn baby care increased significantly after education(t=8.22, df=38, p=0.0001) Suggestions for further studies and nursing practice were as follows. 1. We suggest studies by randomized control-group pretest-posttest design or nonequivalent control group pretest-posttest design will be done. 2. We suggest follow-up studies to find if mothers's confidence will last or not after discharge. 3. We suggest general hospitals to establish a phone-counseling system.
