Discharge plans should be considered during rehabilitation depending on the location specified by the patients. This study aims to compare the demographics and rehabilitation function according to discharge location in people with rehabilitation one month after discharge. Among 300 discharged patients, 146 were discharged to their homes, 154 were transferred to facilities such as nursing homes. The results showed that rehabilitation function that scored using the modified Barthel Index were different according to discharge location. That is, the modified Barthel Index scored greater in home discharged patients than counter group. However, the home discharged patient's physical function and daily activities showed scores that required rehabilitation. Differentiated strategies should be needed for home and facility visit rehabilitation programs for rehabilitated patients.

Function Point Method have been applied to measure software size estimation in industry because it supports to estimate the software's size by user's view not developer's. However, the current function point method has some problems for example complexity's upper limit etc. So, In this paper, an enhanced function point model. Micro FP model, was suggested. Using this model, software effort estimation can be more efficiently because this model has some regression equation. This model specially can be applied to estimate in detail the large application system's size Analysis results show that measured software size by this Micro FP model has the advantage with more correlative between the one of LOC, as of 10 applications operated in an large organization.

Objectives：The major goal of this study was to investigate and compare the behavior problems and mothers' rearing pattern between adolescent psychiatric patients either neglected or rejected by peer and those who were neither neglected nor rejected by peer. Methods：Adolescent psychiatric patients(N=25) performed peer neglect scale, peer reject scale. And their mothers performed the part of Child Behavior Checklist(CBCL), Maternal Behavior Research Instrument(MBRI), the scale for the maternal concern about the social life of their own patients, and the scale for maternal concern about the friendship of their own patients. According to the score of the peer neglect scale and the peer reject scale, we divided the patients into 'peer neglect-reject' group(n=15) and ‘on-loneliness’ group(n=10), and compared the scores of other scales between each group. Also, we investigated the correlation among all scales. Results：1) The scores of the part of CBCL(p<.05), depressed/anxious subscale of CBCL(p<.05) and thought problem subscale of CBCL(p<.01) in peer neglect-reject group were significantly higher than those in non-neglect group. The score of peer neglect scale was significantly correlated with that of the part of CBCL(r=.516), depressed/anxious subscale of CBCL(r=.483), thought problem subscale of CBCL (r=.651), social problem subscale of CBCL(r=.517). And the score of peer reject scale was significantly correlated with that of attention subscale of CBCL(r=.414), thought problem subscale of CBCL(r=.446), social problem subscale of CBCL(r=.531). 2) But, each group was not significantly different on the scores of MBRI, the scale for the maternal concern about the social life of their own patients, and the scale for maternal concern about the friendship of their own patients. And there were no significant correlation between the scores of peer neglect / peer reject scale and those of scales for maternal rearing pattern. Conclusion：The thought problem and depression/anxiety problem of adolescent psychiatric patients neglected or rejected by peer were estimated more higher than those of adolescent psychiatric patients neither neglected nor rejected by peer. But, from the view of maternal rearing pattern, each 2 groups seemed not to be different. Further research using more subjects will be needed.

This study was done to examine changes of plasma homovanillic acid(HVA), 5-hydroxyindoleacetic acid(5-HIAA), and HVA/5-HIAA ratio during an 8-week clozapine trial and to investigate the relationship between the plasma monoamine metabolites and treatment responses. Twenty-seven chronic schizophrenic patiens were treated for 8 weeks with clozapine. The psychopathology was assessed at baseline just clozapine trial and then every 2 weeks until the end of 8-week clozapine treatment using the Positive and Negative Syndrome Scale(PANSS) and the Clinical Global Impression scale(CGI). The plasma HVA and 5-HIAA levels were measured also biweekly using high preformance liquid chromatography with electrochemical detection method. Plasma HVA and 5-HIAA levels were significantly decreased during a 8-week clozapine treatment, although plasma HVA/5-HIAA ratio showed no significant change. The changes of plasma HVA levels were in significant correlations with the changes of PANSS positive scores, of general psychophathology scores, and changes of total socres. The changes of plasma 5-HIAA levels were in signfificant correlations with the changes of PANSS negative scores. But the changes of plasma HVA/5-HIAA ratio had no significant correlation with any PANSS subscale score changes. 48% of the patients treated with clozapine was categorized as responders, who showed at least a 20% decrease in PANSS total socre and a CGI severity score of mildly ill or less(${\leq}3$) at the end pint of the study. The baseline plasma HVA levels and HVA/5-HIAA ratio were significantly higher in responders(N=13) than in nonresponders (N=14). But no significant difference in baseline levels of plasma 5-HIAA was found between responders and nonresponders. At the end point of the study, there was significant difference in the change of plasma HVA between responders(40.3% decrement) and nonresponders(3.1% increment). But no signficant differences in the change of plasma 5-HIAA and the change of plasma HVA/5-HIAA ratio between responders and nonresponders were observed. These results suggest that the antipsychotic effect of clozapine on positive symptoms may be associated with dopaminergic blocking activity, and that on negative symptoms may be associated with serotonergic blocking activity. The baseline plasma HVA levels and the change of HVA levels from baseline may be useful predictors of treatment response with clozapine.

Background : Interstitial lung disease has various manifestations that are differentiated by their pathology, progress and treatment. However, all manifestations eventually progresses to pulmonary fibrosis. Recent studies have shown that apoptosis of pulmonary epithelial cells might be related to pulmonary fibrosis. The correlation of the apoptotic index with the clinical manifestations, pathological findings, HRCT findings and the response to treatment were examined. Materials and Methods : Twenty subjects (14 men, 16 women), who had been diagnosed with interstitial lung disease through an open lung biopsy, were enrolled in this study. The subtypes were one AIP, two NIP, eight BOOP, and seven UIP cases. The apoptotic index was scaled from 0-2 depending on the fraction of positive staining cells by TUNEL method. The clinical severity was assessed by a modification of a previously developed CRP scoring system. The pathologic scores were based on 4 components: fibrosis, cellularity, desquamation, and granulation. In the HRCT study, each lobe was scored by the radiologists on a scale for both fibrosis and ground-glass attenuation. The treatment response was assessed by an increase in more than 10% of the CRP score, and comparing the results 3 months before and after treatment. Results : The apoptotic index showed no correlation with the CRP and HRCT scoring system. The apoptotic index correlated with the pathologic elements including fibrosis, cellularity and the desquamation score (p<0.05). Of the 16 patients who received corticosteroid therapy, 9 patients (56.3%) responded to therapy. There was no correlation between the response to corticosteroid and the apoptotic index. In the case of patients with acute and subacute ILD, the apoptotic index showed a correlation with the cellularity, desquamation, and the total histological score (p<0.05). In the case of patients with chronic ILD, the apoptotic index correlated with the fibrosis and cellularity score (p<0.05). Conclusion : Apoptosis of the pulmonary epithelial cells is implicated in the pathogenesis of interstitial lung disease particularly on a pathological basis.

Background : Most current research using prognostic scoring systems in critically ill patients have focused on prediction using the first intensive care unit (ICU) day data or daily updated data. Usually the mean ICU length of stay in Korea is longer than in the western world. Consequently, a more cost-effective and practical prognostic parameter is required. The principal aim of this study was to assess the prognostic value of the seventh day(7th day : the average mean ICU length of stay) APACHE III score in a medical intensive care unit. Methods : 241 medical ICU patients from July 1997 to April 1998 were enrolled. The 1st and 7th scores were measured by using the APACHE III scoring system and compared between survivors and non-survivors. Logistic regression analysis was performed to determine the relationship between the $1^{st}$ and $7^{th}$ APACHE III scores and the mortality risk. Results : 1 )The mean length of stay in the ICU was $10.3{\pm}13.8$ days. 2)The mean $1^{st}$ and $7^{th}$ day APACHE III scores were $59.7{\pm}30.9$ and $37.9{\pm}27.7$. 3) The mean $1^{st}$ day APACHE III score was significantly lower in survivors than in non- survivors($49.9{\pm}23.8$ vs $86.3{\pm}32.3$, P<0.0001). 4)The mean $7^{th}$ day APACHE III score was significantly lower in survivors than in non- survivors($30.1{\pm}18.5$ vs $80.1{\pm}30.4$, P<0.0001). 5)The odds ratios among the $1^{st}$ and $7^{th}$ day APACHE III scores and the mortality rate were 1.0507 and 1.0779 respectively. Conclusion : These results suggest that the seventh day APACHE III score is as useful in predicting the outcome as is such like the first day APACHE III score. Therefore, in comparison to the daily APACHE III score, measuring the $1^{st}$ and $7^{th}$ day APACHE III scores are also useful for predicting the prognosis of critically ill patients in terms of cost-effectiveness. It is suggested that the $7^{th}$ day APACHE III score is useful for predicting the clinical outcome.

Purpose: This study investigates the relationship between sleep duration, sleep quality, time use, and dietary quality of adolescents. Methods: A cross-sectional study was conducted, enrolling 423 high school students (112 male and 311 female students) in Chungnam using a questionnaire comprising general characteristics, sleep status, use of time, and Nutrition Quotient for Korean Adolescents (NQ-A). Results: On weekdays, male students reported getting 6.6 hours of sleep, which was significantly higher than the 5.8 hours reported by female students. The sleep quality score between male and female students was not significantly different on weekdays and weekends. Comparing the students categorized as getting 6 hours of sleep duration on weekdays and 8 hours on weekends, a significantly higher total NQ-A score was obtained for the long sleep duration group of female students on weekdays. In male students who reported increased screen time on weekdays and study time on weekends, there was a greater frequency of short sleep duration. Our data also revealed that the longer the sleep duration higher the NQ-A score. In addition, higher NQ-A scores were determined with shorter screen time and more prolonged exercise time. Conclusion: Our results suggest that intense study time and excessive use of smartphones have a negative effect on sleep in high school students. In addition, poor sleep quality and lack of sleep are likely to affect eating habits and nutritional status. Therefore, there is a need to provide nutritional education to adolescents imparting knowledge that associates desirable sleep habits and the correct use of time.

본 연구에서는 국내의 항공사진측량에서 적용되지 않고 있는 광속조정 Program을 구현하였다. 또한, 구현된 프로그램을 이용하여 과천지역에 대한 측량자료를 처리하였다. GPS를 이용하여 결정한 카메라 노출중심 위치를 이용하여 광속조정에 적용한 결과는 지상기준점수가 감소하여도 정확도는 완만하게 저하되었으나, 지상기준점만을 이용하여 광속조정에 적용한 결과는 지상기준점수가 감소함에 따라 정확도는 급격하게 저하되었다. GPS를 이용하여 결정한 카메라 노출중심 위치를 광속조정에 적용한 결과 블록 가장자리에 배치한 4개의 지상기준점 만으로 공공측량에 적합한 결과를 얻을 수 있었다. 본 연구를 통하여 GPS로 결정한 카메라의 노출중심위치를 항공삼각측량에 적용할 경우 필요한 지상기준점수를 축소함으로써, 비용을 절감할 수 있을 것으로 판단된다.
