靑少年의 精神建康과 家庭環境 變因과의 관계 : 高等學生을 中心으로 Centering on the highschool students
강현숙,유가효 啓明大學校 生活科學硏究所 1990 科學論集 Vol.16 No.-
This study was designed to investigate the relation of variables of home environment to mental health of adolescences. The subjects employed were 868 students who are 1st grade of 10 highschools in Taegu city. The measurement of mental health consisted of Korean manual of Symptom Checklist-90-revision. Data were analyzed according to mean, standard deviation, t-test, X²-test, one way and two way ANOVA by using SAS and SPSS Programs. The results are as follows : 1. The healthy group of all the subjects was 49.42% and the other mental health condition showed 25.46% for protective group and 25.12% for unhealthy group. 49.42 percents of all the subjects showed the perfect healthy condition and the other 50.58% showed the unhealthy symptoms. The psychoticism was highest in the unhealthy group. The academic highschool students showed the higher points than that of vocational highschoolers in the obsessive-compulsive symptoms(P<.01) and depression(P<.05). In the condition by sex, the mean value of females(54.07) was somewhat higher than that of males(51.03). The mental health by sex showed the significant difference to the other 7 symptoms besides the somatization and phobic anxiety and to the mental health by group(P<.001). 2. The socio-economic status of family didn't show the significant difference to 9 mental health symptoms and groups. The order of birth didn't show the significant difference to 9 mental symptoms and to mental condition by group(P<.05). On the one hand, family pattern showed the significant difference to the depression(p<.01)and anxiety(P<.05)of 9 symptoms for mental health. Its difference in mental health condition by group appeared significantly(P<.05) The condition of parental absence showed the significant difference to interpersonal sensitivity(P<.05), anxiety(P<.05), paranoid ideation(P<.01)and psychoticism(P<.05)of 9s. The absence of father showed the significant difference to the other 7 symptoms besides anxiety and phobic anxiety, also to the mental health by group.(P<.01) However, the absence of mother didn't show the significant difference to 9 symptoms for mental health and to mental health groups. Of the process variables of home environment, the father's child rearing attitude showed the significant difference to 7 symptoms besides somatization and interpersomal sensitivity of 9 symptoms for mental health. The mother's child rearing attitude showed the significant difference to the obsessive compulsive(P<.05). depression(P<.05), hostility(P<.01) and the psychoticism(P<.05), but didn't show the significant difference to the mental condition by group(P<.05). The type of concern of parents showed the significant difference to 8 symptoms besides the phobic anxiety and to mental health by group(P<.05). The degree of satisfaction on their fathers and mothers showed the significant difference to 9 symptoms for mental health and to group for mental health. The marital relation between father and mother showed the significant difference to 7 symptoms besides the anxiety and phobic anxiety and to mental health by group. The domestic peace showed the significant difference to 9 symptoms for mental health and to mental health by group(P<.001). Accordingly, the mental health of adolescence seems to be more affected by the process variables rather than by the status variables of home environment.

The security of Busan waterfront space mostly depends on the reclamation of the coastal zone. The temperature variation is caused by the reclamation, and the model formula of correlation with the reclamation quantity in the coastal zone of Busan is derived(X=logl0α, α=the total of the reclamation quantity). For the determinating coefficient γ²=0.86609 Y= - 157.06659 + 91.766855X - 16.6357X² + 1.0534768X³- 0.006741X⁴ From this, the later temperature increase followed by increase of the reclamation quantity is predicted.

This study started with the measured experiment of climatic characteristic at the coastal reclamation area formed by the reclamation and development which is inevitable selection presently. As a result of the examination, the climate variation is predicted to be large in summer and the salt concentration is shown in the order of top layer, bottom layer and intermediate layer. Therefore, the greens space and wind path are occupied at the coastal reclamation.

Chronic kidney disease (CKD) occurs in more than 15% of the dogs over 10 years of age and causes irreversible renal function deterioration. Therefore, it is important to diagnose CKD early and treat the disease properly. The purpose of this study aimed to to evaluate the clinical utility of urine albumin/creatinine ratio (ACR) using POC (point-of-care) device as an early detection urinary biomarker in CKD dogs and to confirm the correlation between ACR and other known CKD biomarkers. Urine and serum samples were obtained from 50 healthy dogs and 50 dogs with CKD. Serum blood urea nitrogen (BUN), creatinine, and symmetric dimethylarginine (SDMA) concentrations, and urine protein creatinine ratio (UPC) were measured. Urine specific gravity (USG) was evaluated using refractometer, and ACR was measured using an i-SENS A1Care analyzer. The ACR values of dogs with CKD were significantly different from those of healthy dogs (p < 0.001), as with other renal biomarkers. ACR showed significant differences between healthy dogs and dogs with CKD at every IRIS stage (p < 0.005), whereas no significant differences were observed between dogs with CKD IRIS stage I and healthy dogs with UPC. There are significant positive correlation between ACR and BUN (r = 0.611, p < 0.001), creatinine (r = 0.788, p < 0.001), SDMA (r = 0.747, p < 0.001), and UPC (r = 0.784, p < 0.001), and significant negative correlation between ACR and USG (r = -0.700, p < 0.001). In receiver operator characteristic curve analysis, the area under the curve (AUC) was 0.982 (95% CI 0.963-1.000, p < 0.001), with an optimal cut-off value of 64.20 mg/g (94% sensitivity and 94% specificity). Thus, ACR is a useful urinary biomarker for the early diagnosis of proteinuria in CKD and combined use of ACR and other renal biomarkers may be helpful for early diagnosis and prevention of CKD in dogs.

우리나라의 산림자원 중 유령림에 포함되는 I 영급(10년생 이하)은 입목이 존재함에도 불구하고 임목축적을 ‘0’으로 가정하여 국가통계를 산출하고 있으며, 온실가스 배출 및 흡수량 산정을 위한 탄소흡수량에서도 누락되고 있다. 지속가능한 산림경영의 이행 및 산림부문 탄소저장량을 산출하기 위해서는 유령림의 산림자원에 대한 정확한 통계정보의 수집이 필요하다. 본 연구는 유령림의 초기 생장 특성을 파악하고 국가산림자원조사에서 수집된 자료를 활용하여 유령림의 임목축적을 추정할 수 있는 방법을 개발하기 위하여 수행하였다. 유령림의 초기 생장 특성을 분석하기 위하여 유령림의 초기 생장에 관한 문헌조사, 수종별 수간석해 분석 및 현실림 임분수확표에 의한 지위지수별 유령림의 생장 특성 등을 분석하였다. 결과적으로 유령림에서 대부분의 입목은 흉고직경 6 cm 미만으로 나타났으며, 흉고직경 6 cm에 도달하는데 평균 12년이 소요되는 것으로 분석되었다. 국가산림자원조사 자료를 활용하여 유령림의 임목축적을 산출하기 위해서는 치수조사구에서 근원경의 경급별 평균묘고가 조사되어야 하며, 교목을 비롯한 다양한 관목이 조사되고 있으므로 교목 수종을 구분할 수 있도록 분석시스템의 개선이 필요한 것으로 나타났다. The growing stocks of young forests that are less than10 years of age have been excluded from the Korean forest resource statistics, despite the existence of standing trees; however, sustainable forest management and carbon removals in the forestry section require complete information regarding forest resources. This study developed a method to estimate the growing stocks for young forests from National Forest Inventory (NFI) data. After reviewing previous research on growth characteristics for young forests, we conducted stem analysis of major species, and examined stand characteristics by site index, based on real yield tables. Our statistical analysis results showed that there were few standing trees with diameters at breast height (DBH) above 6 cm in young stands, and that it would have taken 12 years, on average, to reach 6 cm DBH. This suggests that mean tree height by diameter should be assessed at the root, in order to assess growing stocks for young stands through the NFI. Moreover, the database system should be improved to differentiate tree species, since diverse shrubs, including trees, have been surveyed.
