The management of blood inventory is very important within the medical care system. The efficient management of blood supplies and demands for transfusion is of great economic and social importance to both hospitals and patients. Fro any blood type, there is a complex interaction among the optimal inventory level, daily demand level , daily supply level, transfusion to crossmatch ratio, crossmatch release period, issuing policy and the age of arriving units that determine the shortage and outdate rate. In this paper, we develop an efficient decision rule for blood inventory management in a hospital blood bank which can support efficient hospital blood inventory management using simulation, The primary use of the efficient decision rule will be to establish minimum cost function which consists of inventory levels , period in inventory, outdate and shortage rate for whole blood and various component inventories for a hospital blood bank or a transfusion service, If the adminstrator compute the mean daily demand for each blood type, the mean daily supply for each blood type, the length of the crossmatch release period and the average transfusion to crossmatch ratio , then it is possible to apply the efficient decision rule to compute the optimal inventory level, inventory period , outdate and shortage rate. This rule can also be used as a decision support system that allows the blood bank adminstrator to do sensitivity analysis related to controlled blood inventory parameters.

This study was designed and undertaken to analyse the factors associated with sexual satisfaction in diabetic patients. The data were collected from September to November, 1997. The subjects in this study were 77 diabetic patients who visited to check their blood glucose level to the outpatient department of internal medicine in one of hospitals located in Taejon city, The questionnaires developed by Derogatis L. R. were used. Data were analysed using percentages, means, 1-test, ANOVA and Peason-correlation coefficients, done with the SAS program. The results of this study were as follows ; 1. The mean score of sexual satisfaction in diabetic patients was higher than the mid level as 3.14 points in the 5 points scale and male patients' score was a little higher than female's. 2. The mean score of factors associated with sexual life was 3.54 points in spouses' support, 3.44 points in sexual attitude and 2.60 points in body image in the 5 points scale, and 2.76 points in the sexual act in the 6 points scale. The score of above all factors were higher in male patients than female patients. 3. The significant factors associated with sexual satisfaction were spouses' support, body image and sexual act. That is, the higher spouses' support, the more positive body image and the more frequent sexual act, the higher patients' sexual satisfaction. 4. In the relationships between the sexual satisfaction and the general characteristics of the diabetic patients, only religion and the period of disease were statistically significant differents, but the relationships between the sexual satisfaction and the period of disease showed a significant inverse correlation. This results showed that the degree of sexual satisfaction in diabetic patients was relatively high. The major factors associated with sexual satisfaction were spouses' support, body image and sexual act, religion and the period of disease. So, the above factors have to be considered during the nursing intervention on diabetic patients' sexual life.

Purpose - The purpose of this study is to examine how a broad palette of government support measures and firms' membership in government-developed clusters are related to firms' openness in innovation processes. Design/methodology/approach - Empirically, this study analyzes the Korea Innovation Survey 2018 data on the innovation activities of 1,450 Korean R&D-active manufacturing firms in a three-year period from 2015 through 2017. Findings - The results suggest that firms engage in open innovation to a greater extent--as measured by the breadth of external collaborating partners and of the utilized external sources of knowledge--when they are provided with a broader palette of government support measures and are located in government-developed clusters. However, the effect of diverse government support measures is attenuated for firms located in these clusters. Research implications or Originality - This study contributes to the innovation literature by illuminating how firms' open innovation can be understood in a national innovation system. Moreover, it provides valuable implications for firms seeking to obtain government support and collaborate with others.

The number of test samples was calculated by setting the reliability growth management test period considering the weapon system development period. The optimal reliability growth management test design condition was 80% reliability, 60% confidence level, and 6 months of test period. At this time, it was analyzed that 4 test samples were required if 0 failure occurred, and 9 test samples were required if 1 failure occurred. Using the method of determining the number of samples presented in this paper, it can be used as a basis for acquiring a budget for the number of samples for reliability growth management when switching from the exploratory development stage to the system development stage.

Negative life events, self-esteem, perceived social support, and maladjustment were studied longitudinally among late elementary children. Subjects were 241 boys and girls for depression and 258 for antisocial behavior. The instruments were the Adolescent Perceived Events Scale, the Rosenberg Self-Esteem Scale, the Social Support Scale for Children, the Revised Korean Version of the Center for Epidemiologic Studies' Depression Scale, and the Antisocial Behavior Scale. The results showed that the way variables were reciprocally related to one another in patterns over a period of one year differed by internal and external adjustment. For depression, depression at Time 1 had effects on self-esteem, social support, and depression at Time 2. For antisocial behavior, negative life events at Time 1 influenced negative life events, self-esteem, social support, and antisocial behavior at Time 2. The findings were discussed in relation to the effects of negative life events, self-esteem, and perceived social support on maladjustment.

Purpose: This study was to determine the mediator or moderator role of social support in the relationship between stress and depression among family caregivers of older adults with dementia. Method: Sixty nine family caregivers were randomly selected from health care centers in P city and a face-to-face interview was conducted using questionnaires from January to May of 2002. Data were analyzed with descriptive statistics, Pearson correlation, and hierarchical multiple regression using SPSS program. Result: Family caregivers of older adults with higher dependency in ADLs and higher problematic behaviors, provided care to the older adults for a longer period of time, and perceived less social support reported higher depression. Social support showed mediating effects between stress and depression, while did not show moderating effects. Elderly dependency on ADLs and caregiving duration decreased perceived social support and decreased social support increased depression. Conclusion: To increase family and social support to the caregivers of more functionally impaired elderly, family education to increase emotional support and physical assistance to the caregivers and broader and flexible application of social support such as increasing accessibility to the elderly daycare service with lower price may prove beneficial.

The demand and supply of programs of parenthood programs for fathers are increasing with changes in the image of male parents. Under this backdrop, a necessary requirement is to analyze the current status of father programs that are spearheaded by governments and the satisfaction with them to determine if they actually meet the needs of fathers. This study conducted such an examination for the fatherhood programs that were provided as a mandatory public service by the Healthy Family & Multicultural Family Support Center in 2017. To this end, the research analyzed performance and satisfaction data on 776 projects, including 1293 programs that were required for provision in 101 integrated centers nationwide. The results showed that satisfaction with fatherhood programs differed according to the project area, the location of a center, the period of implementation, the methods of proceeding, the participation unit (whether an entire family or an individual family member), the number of participants, and the number of sessions. Overall, the level of satisfaction was higher in "fathers meetings" (under the community domain) than "support for the father role" (under the family relationship domain). In relation to implementation period, satisfaction with the programs was high in the 4th quarter of implementation. Satisfaction with the programs was also higher for culturally based initiatives than education-oriented programs. Satisfaction was higher when the participation unit was the family than when such unit was the individual. The smaller the number of participants, the higher the satisfaction level. Finally, the number of sessions was deemed satisfactory when it was completed in more than four sessions. This study is meaningful in that it provides the basis of effective use of the government budget by analyzing the status and satisfaction of the fatherhood programs, which have been implemented since the integration of the Healthy Families & Multicultural Family Support Center.
