This paper deals with performance measures for recoverable item control where the demand process is time-dependent. The performance measure is essential for modelling a multi-echelon inventory problem for repairable items. Most repairable items are expensive and have a great influence on the performance of equipments. Thus the information on these items is very useful to the decision maker. The purpose of this paper is to derive the system performance measure and the part(component) performance measure considering a cannibalization policy under the dynamic environment.

The purpose of this study is to investigate the effect of neuromuscular re-education program and general intervention program. It is focused on difference between changes of experimental before and after on 20 stroke patient's motor control ability. The obtained results are as follows; In change in motor control ability, neuromuscular re-education program group about the motor control ability was a significant difference(p<.01). And traditional intervention program group, the motor control ability was a significant difference in all of items (p<.01; p<.05) but, were not a significant difference in bladder management, social interaction, problem solving and memory. And also comparison of change in motor control ability between the experimental group and control group, the between-subjects factors were a significant difference. Most of the functional items on the functional items on the functional measurement and neuromuscular function measurement are concerned with the physical autonomy of the hemiplegic patients. More in depth knowledge may be acquired about the distribution of physical and motor control patterns with respect to the degree of neurologic deficit for the enhencement of residual motor control function in hemiplegia. In conclusion, the neuromuscular re-education program was more effect then traditional intervention program in motor control ability.

수출통제는 1949년 미국주도의 COCOM에서 국제수출통제체제가 시발점이라 볼 수 있다. 그 후에도 많은 국제적 노력이 계속 되었는데, 1969년의 핵비확산조약(NPT), 1970년의 쟁거위원회(ZC), 1978년의 핵공급국 그룹(NSG), 1985년의 호주그룹(AG), 1987년의 미사일기술통제체제(NTCR) 또한 1990년 베르린장벽이 철거되면서 COCOM은 1995년 Wassenaar Arrangement(WA)이 창설되었다. 수출통제의 개념은 특정지역에 대한 무기류 및 그 부품의 수출통제에서 무기류 또는 그와 관련된 민군겸용물품 및 기술이 분쟁지역이나 우려국가 테러집단과 같은 비국가 행위자(Non-state actor)의 손에 들어가지 않도록 예방하거나 차단하는 것으로 변화되었으며 이를 비확산통제 (Nonproliferation Control)라고 표현한다. 수출통제의 품목은 과거의 재래식 무기류 뿐만 아니라 다량살상무기(Weapons of Mass Destruction: WMD) 및 그 운반수단인 미사일의 제조, 개발, 사용 또는 보관 등의 용도로 사용 또는 전용될 수 있는 일반 산업용품(Dual Use Item)까지도 포함되게 되었다. 9.11테러는 국제사회에 영향을 마쳤다. WMD 확산방지를 위한 노력이 국제안보의 최대 현안사항으로 등장하게 되었다. 본 연구는 비확산체제의 국제법상의 쟁점 및 문제점을 도출하고 비확산규범의 효과적인 집행과 비확산체제의 강화에 따른 개선방안을 제시하는데 그 목적이 있다. 또한 남북경제협력에 있어서 남북관계에 쟁점이 될 수 있는 전략물자 수출통제체제제도를 효율적으로 운영하여 국가안보 및 국제평화에 기여하여야 한다. 최근 북한은 미사일 시험, 핵실험 등을 강행함으로써 국제사회에 많은 지탄을 받고 있으며, 지금 국제사회는 유엔결의사항의 이행과 관련하여 중국과 한국을 비롯한 관련 당사국의 수출 통제 준수여부에 많은 관심을 기울이고 있다.

방송 디스크는 다수의 이동 클라이언트에게 정보를 전파하는 통신구조이다. 방송 디스크에서 서버는 데이터베이스에 저장된 모든 데이터를 연속적으로 방송하며, 클라이언트는 방송 채널을 감시하여 자신이 원하는 데이터를 수신한다. 이런 관점에서 방송 채널은 클라이언트가 데이터를 액세스할 수 있는 디스크의 역할을 담당한다. 본 논문에서는 서버에서 방송 데이터가 갱신될 경우, 클라이언트에서 실행되는 읽기 전용 트랜잭션의 정확성을 보장하기 위한 타임스탬프 기반 동시성 제어(Timestamp Based Concurrency Control: TCC) 기법을 제안한다. 기존에 제안된 동시성 제어 기법들은 트랜잭션의 철회율을 줄이기 위하여 추가적인 제어 정보들을 방송함으로써 방송 대역폭의 상당 부분을 소비한다는 단점을 갖는다. 이와는 달리, TCC는 방송 데이터의 타임스탬프 필드에 그 데이터를 갱신한 서버 트랜잭션들의 순서를 반영시키고, 이를 수신한 클라이언트에서는 타임스탬프를 이용하여 자신의 읽기 전용 트랜잭션의 정확성을 검사함으로써 보다 많은 트랜잭션 실행을 허용한다. 그 결과, TCC는 서버로부터 방송되는 제어 정보의 양을 최소화하면서 읽기 전용 트랜잭션의 철회율을 줄일 수 있다는 장점을 갖는다.

This study was undertaken in order to examine the relationship of control, perceived health status, self efficacy, social support, and demographic characteristics to health promoting lifestyle of nursing students, and to determine factors affecting health promoting lifestyle of nursing students. The subjects were 270 students of a single university in Busan. The instruments used for this study was a survey of general characteristics, health promoting lifestyle (47 items), control(8 items), perceived health status(6 items), self-efficacy(17 items), and social support(18 items). Data analysis was done by use of mean, percentage, t-test, ANOVA, Pearson Correlation coefficients and stepwise regression with a SPSS PC+ program. The results of this study are as follows : 1) The average item score for the health promoting lifestyle was less than 2.43. In the sub-categories, the highest degree of performance was interpersonal relationships (2.94) and the lowest degree was health responsibility(1.93). 2) Students who were older and higher scores in health responsibility and interpersonal support subscale. Students who had higher grade had higher scores in health support subscale. Students who had experienced disease had higher scores in health responsibility subscale. Students who had experienced exercise had higher scores in health responsibility, exercise and nutrition subscale. 3) Significant correlation between control and self-efficacy, self-efficacy and social support was found. 4) Significant correlations was found between most of the subscales and total health promoting lifestyle. 5) Social support revealed significant correlations with total health promoting lifestyle and all subscales of health promoting lifestyle. Control revealed significant correlations with total health promoting lifestyle and self actualization and health responsibility. Perceived health status revealed significant correlations only with the exercise and nutrition subscale. Self-efficacy revealed significant correlation with the total health promoting lifestyle and all subscales of health promoting lifestyle except exercise and nutrition, stress management subscale. 6) Social support was the highest factor predicting health promoting lifestyles of nursing students(31%). Social support, excercise self-efficacy and control accounted for 35% in health promoting lifestyle of nursing students.

The objectives of this study were to verify the effectiveness of the Theory of Planned Behavior in predicting exercise intention and exercise behavior, and to examine the determinants of exercise intention and exercise behavior in the sample of middle-aged women. The subjects who participated in this study were 263 middle-aged women. The instruments used for this study was a survey of general characteristics, attitude (18 items), subjective norm (2 items), perceived behavioral control (19 items), intention (3 items), and exercise behavior (7 items and 23 items for each). Analysis of data was done by use of descriptive statistics and correlation analysis with SAS PC program. The hypothetical model based on the Theory of Planned Behavior was tested by use of LISREL 8.12a program. The results of this study were as follows. 1) The overall fit of the hypothetical model to the data was good(chi-square=11.76, p=0.03, RMSEA=0.07, standardized RMR= 0.03, GFI=0.99, AGFI=0.94, NFI=0.97, NNFI=0.95). 2) Perceived behavioral control, attitude, and subjective norm were significant determinants of exercise intention, and these variables explained 35% of the total variance of exercise intention. 3) Perceived behavioral control, intention, and attitude were significant determinants of exercise behavior. But, subjective norm was not a significant determinants. These four variables explained 69% of the total variance of exercise behavior. In conclusion, this study shows the applicability of the Theory of Planned Behavior in explaining exercise behavior of middle-aged women, and suggests that health care providers should focus on perceived behavioral control and attitude rather than subjective norm to improve exercise behavior of middle-aged women.

The purpose of this study was to find any correlations among Postural Assessment Scale for Stroke (PASS), Modified Barthel Index (MBI), Tone Assessment Scale (TAS), Motor Assessment Scale-Gait (MAS-G), Fugl Meyer-Balance (FM-B), and to predict MBI from subscales of the PASS. The subjects were 41 stroke patients of the Korea National Rehabilitation Center in Seoul. The main outcome measures were postural control (PASS), gait (MAS-G), Balance (FM-B), Tone (TAS), ADL (MBI). The data was analyzed using the Pearson product correlation. PASS scale was used between other clinical and instrumental indexes, multiple stepwise regression analyses were performed to identify prognostic factors for ADL incline, and Cronbach's alpha coefficient was used to identify internal consistency on PASS scale. The results of this study areas follows: 1. The highest level was sitting without support, the lowest level was standing on paretic leg on PASS scale. The highest level was chair/bed transfer, the lowest level was bathing on MBI. 2. All items of the PASS, except postural tone were significantly correlated with Gait, Balance, MBI (p<.01), 3. The Internal Consistency (Cronbach's alpha coefficient=.85) was very high, indicating that the PASS is homogeneous and is likely to produce consistent response. Furthermore, the sums of maintaining position items and of changing-position items were strongly correlated (r=.64, p<.05) and there were significant correlations between sums of PASS, sums of maintaining position items (r=.87, p<.01), and changing-position items (r=.93, p<.01). 4. The standing without support of the PASS items was the strongest variance ($R^2$=.85) of the predicting ADL function. These findings provide strong evidence of the predictive value of the postural control on gait, Balance, ADL function in stroke patients and to can provide a reference for the successful therapeutic program and more improved functional recovery.
