The crystal structure of fully dehydrated partially Cs+-exchanged zeolite X, [Cs52Na40Si100Al92O384], a = 24.9765(10) A, has been determined by single-crystal X-ray diffraction techniques in the cubic space group Fd3 at 21 °C. The crystal was prepared by flow method for 5 days using exchange solution in which mole ratio of CsOH and CsNO3 was 1 : 1 with total concentration of 0.05 M. The crystal was then dehydrated at 400 °C and 2 × 10-6 Torr for 2 days. The structure was refined to the final error indices, R1 = 0.051 and wR2 (based on F2) = 0.094 with 247 reflections for which Fo > 4σ (Fo). In this structure, about fifty-two Cs+ ions per unit cell are located at six different crystallographic sites with special selectivity; about one Cs+ ion is located at site I, at the centers of double oxygen-rings (D6Rs), two Cs+ ions are located at site I', and six Cs+ ions are found at site II'. This is contrary to common view that Cs+ ions cannot pass sodalite cavities nor D6Rs because six-ring entrances are too small. Ring-opening by the formation of ?OH groups and ring-flexing make Cs+ ions at sites I, I', and II' enter six-oxygen rings. The defects of zeolite frameworks also give enough mobility to Cs+ ions to enter sodalite cavities and D6Rs. Another six Cs+ ions are found at site II, thirty-six are located at site III, and one is located at site III' in the supercage, respectively. Forty Na+ ions per unit cell are located at two different crystallographic sites; about fourteen are located at site I, the centers of D6Rs and twenty-six are also located at site II in the supercage. Cs+ ions and Na+ ions at site II are recessed ca. 0.34(1) A and 1.91(1) A into the supercage, respectively. In this work, the highest exchange level of Cs+ ions per unit cell was achieved in zeolite X by conventional aqueous solution methods and it was also shown that Cs+ ion could pass through the sixoxygen rings.

Purpose: Artificial intelligence (AI) is poised to play a major role in medical diagnostics. Periodontal disease is one of the most common oral diseases. The early diagnosis of periodontal disease is essential for effective treatment and a favorable prognosis. This study aimed to assess the effectiveness of AI in diagnosing periodontal bone loss through radiographic analysis. Materials and Methods: A literature search involving 5 databases (PubMed, ScienceDirect, Scopus, Health and Medical Collection, Dentistry and Oral Sciences) was carried out. A specific combination of keywords was used to obtain the articles. The PRISMA guidelines were used to filter eligible articles. The study design, sample size, type of AI software, and the results of each eligible study were analyzed. The CASP diagnostic study checklist was used to evaluate the evidence strength score. Results: Seven articles were eligible for review according to the PRISMA guidelines. Out of the 7 eligible studies, 4 had strong CASP evidence strength scores (7-8/9). The remaining studies had intermediate CASP evidence strength scores (3.5-6.5/9). The highest area under the curve among the reported studies was 94%, the highest F1 score was 91%, and the highest specificity and sensitivity were 98.1% and 94%, respectively. Conclusion: AI-based detection of periodontal bone loss using radiographs is an efficient method. However, more clinical studies need to be conducted before this method is introduced into routine dental practice.

This study intended to analyze the health promoting behaviors, compare their factors according to the shift pattern of duties of women workers who were working in the industrial workplace and present basic data in planning systematic and effective programs of health promotion for three-shift system and day-duty. Using Quota Sampling, 219 women workers were selected as subjects from 5 workshops which had 50 settled workers up to 300 and 10 factories which had more than 300 located in Taegu and Kyung-Book Province. Data were collected by means of questionnaire from September 12 to September 30, 1998. As the instruments of the study were used Health Promotion Lifestyle Profile(HPLP) which was adapted and adjusted by Seo, Y. O. for health promoting behavior, the one developed by Moon, J. S. (1990) for health-belief, the one developed by Sherer et al.(1982) and then adapted by Oh, H. S. for self-efficacy, and the one developed by Park, J. W. (1985) for social support. The analysis of data were performed with Cronbach's ${\chi}^2$-test, t-test, ANCOVA, Kendal tau, Pearson correlation, Stepwise Multiple Regression test using SPSS program. The results of the study are as follows : 1. There was a significant difference in age(${\chi}^2=32.46$, p=0.000), career (${\chi}^2=18.47$, p=0.000), working day(t=-3.18, p=0.000) by the shift pattern of duties in terms of socio-demographic characteristics. 2. There was a statistically significant difference between the two groups on the health promoting behaviors (t=2,52, p=0.012). The score of three-shift group on health promoting behaviors was 2.27, showing that it was lower by .13 than that of day-duty group(2.40). 3. ANCOVA involving age, career and working day as covariables, which had revealed significant difference before, showed that health promoting behaviors by the shift patterns of duties was significantly different(F=4.88, p=0.028). 4. In consideration of variables that have an influence on health promoting behavior by the shift pattern of duties, social support occupied 19.4% of health promoting behavior in the three-shift group and 22.5% including the sense of self-efficacy. In the day-duty group, social support occupied 34.4% of health promoting behavior. 5. The score of three-shift group(2.94) was significantly lower than that of day-duty group(3.12) in the perceived benefit of health-belief(t= -3.29, p=0.001), while the score of three-shift group (2.48) was significantly higher than that of day-duty group(2.24) in the perceived barrier (t=4.22, p=0.000). In the sense of self-efficacy(t=-4.20, p=0.000), the score of three-shift group(3.24) was significantly lower than that of day-duty group(3.53) while in social support(t=-4.56, p=0.000) the one of three-shift group(2.64) was significantly lower than that of day-duty group(2.88). The suggestions are as follows on the basis of the results of this study : 1. It is required to develop health promoting program that takes the shift pattern of duties of women workers into consideration. In addition, there are special demands on developing nursing strategies for health promoting behavior of three-shift workers. 2. It is required to develop specific strategies for social support which is the most significant factor to the health promoting behavior for women workers. 3. It is necessary to develop some programs for improving the sense of self-efficacy, social support, and health-belief of three-shift workers. To achieve these tasks, industrial nurses should play an active role and improve the ability of self-health care of women workers.

Urban groundwater has a unique hydrologic system because of the complex surface and subsurface infrastructures such as deep foundation of many high buildings, subway systems, and sewers and public water supply systems. It generally has been considered that increased surface impermeability reduces the amount of groundwater recharge. On the other hand, leaks from sewers and public water supply systems may generate the large amounts of recharges. All of these urban facilities also may change the groundwater quality by the recharge of a myriad of contaminants. This study was performed to determine the factors controlling the recharge of deep groundwater in an urban area, based on the hydrogeochemical characteristics. The term ‘contamination’ in this study means any kind of inflow of shallow groundwater regardless of clean or contaminated. For this study, urban groundwater samples were collected from a total of 310 preexisting wells with the depth over 100 m. Random sampling method was used to select the wells for this study. Major cations together with Si, Al, Fe, Pb, Hg and Mn were analyzed by ICP-AES, and Cl, N $O_3$, N $H_4$, F, Br, S $O_4$and P $O_4$ were analyzed by IC. There are two groups of groundwater, based on hydrochemical characteristics. The first group is distributed broadly from Ca-HC $O_3$ type to Ca-C1+N $O_3$ type; the other group is the Na+K-HC $O_3$ type. The latter group is considered to represent the baseline quality of deep groundwater in the study area. Using the major ions data for the Na+K-HC $O_3$ type water, we evaluated the extent of groundwater contamination, assuming that if subtract the baseline composition from acquired data for a specific water, the remaining concentrations may indicate the degree of contamination. The remainder of each solute for each sample was simply averaged. The results showed that both Ca and HC $O_3$ represent the typical solutes which are quite enriched in urban groundwater. In particular, the P$CO_2$ values calculated using PHREEQC (version 2.8) showed a correlation with the concentrations of maior inorganic components (Na, Mg, Ca, N $O_3$, S $O_4$, etc.). The p$CO_2$ values for the first group waters widely ranged between about 10$^{-3.0}$ atm to 10$^{-1.0}$ atm and differed from those of the background water samples belonging to the Na+K-HC $O_3$ type (<10$^{-3.5}$ atm). Considering that the p$CO_2$ of soil water (near 10$^{-1.5}$ atm), this indicates that inflow of shallow water is very significant in deep groundwaters in the study area. Furthermore, the P$CO_2$ values can be used as an effective parameter to estimate the relative recharge of shallow water and thus the contamination susceptibility. The results of our present study suggest that down to considerable depth, urban groundwater in crystalline aquifer may be considerably affected by the recharge of shallow water (and pollutants) from an adjacent area. We also suggest that for such evaluation, careful examination of systematically collected hydrochemical data is requisite as an effective tool, in addition to hydrologic and hydrogeologic interpretation.ion.ion.

최근 세기조절 방사선치료(Intensity Modulated Radiation Therapy, IMRT)와 같은 고 정밀 방사선 치료의 발전과 함께 두 경부 환자의 진단 및 치료 계획 그리고 추적관찰(follw-up)을 목적으로 한 CT 촬영 횟수가 크게 증가하고 있다. 이러한 CT 촬영의 증가와 MDCT와 같은 CT의 발전과 한 검사로 받는 피폭 선량이 상대적으로 다른 검사에 비하여 월등히 크기 때문에 환자 피폭 선량의 정확한 선량 평가가 요구된다. 본 연구에서는 두 경부용 물팬텀(cylindrical water phantom)을 자체 제작하여, 연필형 이온 전리함 및 30 cc 이온 전리함 그리고 LiF:Mg,Cu,P TL 분말을 사용한 열형광 선량 측정법(Thermoluminescent Dosimetry, TLD)을 이용하여 Multi Detector Computed Tomography, MDCT의 흡수 선량 및 체표면 선량을 비교 평가하였다. MDCT의 슬라이스 폭의 일정한 선량 균일성을 확인하기 위하여 콜리메이션 2 mm 단일 빔의 프로필을 1 mm 간격으로 80 mm 측정한 결과 빔의 폭이 12 mm이고 선량 분포는 80~100%로 빔의 출력은 ＋Y 방향으로 높게 나타났다. 물팬텀의 중심부에서 연필형 이온 전리함 및 30 cc 이온 전리함과 TLD의 흡수 선량은 각각 31.83 mGy, 33.58 mGy, 32.73 mGy로 TLD의 흡수 선량은 이온전리함으로 구한 흡수선량과 오차범위 내에서 일치하고 있음을 알 수 있었다. 체표면 10 mm 깊이에서의 TLD 선량은 33.92 mGy로 중심부보다 약 3.5% 높게 평가 되었다. 이러한 흡수선량은 두 경부 환자가 최초 진단을 위한 CT 촬영으로부터 치료계획 및 추적관찰을 목적으로 한 CT촬영까지 4회의 CT촬영을 할 경우, 이로 인한 피폭 선량이 약 14 cGy임을 알 수 있었다. 따라서 방사선치료를 위한 CT 촬영으로 인한 환자의 피폭이 적지않음을 확인하였고 가능한 한 피폭을 줄이려는 노력을 기울여야 할 것이다.

ZERODUR와 용융 석영으로 저산란 반사경을 제작하고 산란 특성을 연구하였다. Bowl feed 법을 이용하여 초연마면인 표면거칠기 0.326 ${\AA}$인 용융 석영 기판과 표면거칠기 0.292 ${\AA}$의 ZERODUR 기판을 얻었다. 이온빔 스퍼터링 방법으로 초연마된 기판 위에 $SiO_2$와 $Ta_2O_5$를 교번으로 22층을 증착하여 다층박막 고반사 거울을 얻었다. 용융 석영 반사경과 ZERODUR 반사경의 산란이 각각 4.6 ppm과 30.9 ppm으로 측정되었으며, 이로부터 산란이 매우 작은 경우 기판의 표면거칠기가 산란을 결정하는 주요 파라미터가 아니라는 것을 알았다. 나아가 반사경의 표면거칠기를 AFM으로 측정한 결과. ZERODUR 반사경이 용융 석영 반사경 보다 박막의 표면거칠기가 2.3배 더 높게 측정 되었다. 이 결과는 기판-박막 경계면에서 박막 형성 초기에 기판의 화학조성 또는 결정방향과 증착물질의 상호관계로 인하여 박막 형성 초기에 표면거칠기가 급격히 나빠져서 발생하는 것으로 유추되었다. SEO 300A으로 접촉각 측정을 하여 Giriflaco-Good-Fowkees-Young 방법으로 표면에너지를 계산하였다. 표면거칠기 0.46 ${\AA}$을 갖는 용융 석영 기판이 표면거칠기 0.31 ${\AA}$을 갖는 ZERODUR 기판보다 접촉각이 더 작고 표면에너지는 크게 나타났다. 이러한 차이가 기판 종류에 따라 박막형성 초기에 표면거칠기를 다르게 하는 한 요인으로 판단되며, 기판의 표면에너지가 높을수록 미려한 박막표면을 얻는 것으로 확인되었다. ZERODUR의 표면에너지 차이를 설명하기 위해 XPS 분석으로 용융 석영은 Si, O로 구성되었고 ZERODUR는 Si, O, Al, Na 그리고 F로 구성되었다는 것을 알 수 있었다.

Recent achievements of scientific research on the pharmacologic activities and the chemical problems of dammalene glycosides, which are considered to be effective principles of Korean ginseng, are reviewed and analyzed in view of structure-activity relationship. 1) S. Shibata and his co-workers detected 12 glycoside spots of dammalene series on the two dimensional T.L.C. of total glycoside fraction from Japanese ginseng, and designated them Ginsenoside Rx(x=a, b, c, g, h, etc.) in the order of increasing Rf-value. The aglycones of those glycosides were characterized to be protopanaxadiol for the Ginsenoside $Rx(x=a,\;b_{1},\;b_{2},\;c,\;d,\;e,\;f)$ and protopanaxatriol for the Ginsenoside $Rx(x=g_{1},\;g_{2},\;g_{3},\;h_{1}\;'h_{2})$. Using Korean ginseng as the material for our study, the author and his coworkers isolated a new dammalene glycoside(Panax Saponin C), which comes under the category of protopanaxadiol glycosides based on the classification of S. Shibata et al., and characterized this saponin to be the glycoside of protopanaxatriol series. Furthermore, Panax Saponin C dissociated into $two\;components(C_{1}\;and\;C_{2}-acetate)$ by acetylation, both of which returned to original Panax Saponin C by deacetylation. Based on this result, more than 13 glycoside components of dammalene series will be expected in the Korean ginseng. 2) The structures of protopanaxadiol and protopanaxatriol, the genuine aglycones of dammalene glycosides, are fully established to be structural analogues by S. Shibata and his co-workers, therefore antagonistic and/or analogical activities will be expected for the pharmacologic activities of these glycoside series of structural analogues. K. Takaki and his co-workers found central nervous system (CNS) stimmulant activity from the glycosides of protopanaxatriol series and CNS-depressant activity from the glycosides of protopanaxadiol series. On the other hand, the author and his co-workers found stimmulating activity on the protein synthesis from both the series of dammalene glycosides with delayed and long-lasting characteristics. This delayed and long-lasting characteristics were also observed in the anti-inflammatory activity of glycosides of protopanaxatriol series on their time course tendency. For the convenience's sake of argument, pluralistic pharmacologic activities of dammalene glycosides, which were observed by many workers at various pharmacologic site, may be classified into two main categories; one is pan-cellular activity and the other is organ specific activity to the certain tissue which is a mass of cells differentiated to a certain direction for their special functions in the body. Based on the data of K. Takaki and those of the authors, following assumption will be probable; Pharmacologic activities of both series of glycosides of protopanaxadiol and protopanaxatriol aglycones may be antagonistic on their tissue-specific activities and analogic on their pan-cellular activities. Therefore, the mixture of these two series of glycosides in an appropriate ratio, as the case of total extract of Korean ginseng, will be probably beneficial to the host by increasing the synthesis of some functional proteins, due to the additive action of pan-cellular activity, and with the disappearance of any significant behavioral symptoms due to the antagonism of tissue specific activity. This fact will probably be the main reason why classical trials of pharmacologists failed in re-discovering the efficacy of Korean ginseng with their behavioral test. 3) The author and his co-workers achieved the synthesis of $C^{14}-labelled\;Panax\;Saponin\;A\;on\;C_{25}-C_{27}\;position\;of\;aglycone$ in the interest of tracer studies in vivo. The method will be applicable to other dammalene glycosides regardless of their chemical structure. 4) The author and his co-workers converted chemically betulafolienetriol, a triterpene component of Betula platyphylla, to the protopanaxadiol, one of genuine aglycone of dammalene glycosides.

One of the important tasks for new parents. especially mothers, is to establish warm, mutually affirming interpersonal relationships with the new baby in the family, with the purpose of promoting the healthy development of the child and the wellbeing of the whole family. Nurses assess the quality of the behavioral characteristics of the maternal-infant interaction. This study examined the relationships between primiparas pereptions of their delivery experience and their maternal infant interaction. It compared to delivery experience of mothers having a normal vaginal delivery with those having a casearean section. The purpose was to explore the relationships between the mother's perceptions of her delivery experience with her maternal infant interaction. The aim was to contribute to the development of theoretical understanding on which to base care toward promoting the quality of maternal-infant interaction. Data were collected directly by the investigator and a trained associate from Dec. 1, 1987 to March 8, 1988. Subjects were 3 random sample of 62 mothers, 32 who had a normal vaginal delivery and 30 who had a non-elective cesarean section (but without other perinatal complications) at three general hospitals in Seoul. Instruments used were the Stainton Parent -infant Interaction Scale(1981) and the Marut and Mercer Perception of Birth Scale(1979). The first observations were made in the delivery room (for vaginally delivered mothers only), followed by day 1, day 2, day 3, and 2 weeks, 4 weeks, 6 weeks and 8 weeks after birth, for a total of 7-8 contacts(Cesarean section mothers were observed on days 4 and 5 but the data not used for analysis). Observations in the hospital were made during the hour prior to scheduled feedings. The infant was placed beside the mother. Later contacts were made at home. Data analysis was done by computer using as SPSS program and indulded X² test, paired t-test, t-test, and Pearson Correlation coefficient ; the results were as follows. 1. Mothers who had a normal vaginal delivery tended to perceive the delivery experience more positively than cesarean section mothers(p＝0.002). The finding supported the hypothesis I that perception of delivery would vary according to the method of delivery. Mothers' perceptions of birth were classified into three dimensions, labor, delivery and the bady. There was a significantly different and positive perception by the vaginally delivered mothers to the delivery experience(p＝0.000) but no differences for labor or the bady according to the delivery method(p＝0.096, p＝0.389), 2. Mothers who had a normal vaginal delivery had higher average maternal-infant interaction scores(p＝0.029) than mothers who had a cesarean section. There were similar higher scores for the 1st day(p＝0.042), 2nd day (p＝0.009), and the 3rd day(p＝0.006) after delivery but not for later times. The findings supported the hypothesis Ⅱ that there would be differences in maternal-infant interaction for mothers having vaginal and cesarean section deliveries. However these differences deccreased section deliveries. However these differences decreased over time . by eight weeks the scores for vaginal delivery mothers averaged 8.1 and for cesarean section mothers, 7.9. 3. The more highly positive the pereption of the delivery experience, the higher the maternal-infant interaction score for all subjects(F＝.3206, p＝.006). The findings supported the hypothesis Ⅲ that there would be correlations between perceptions of delivery and maternal-infant interaction. The maternal infant interaction was highest when the perception of the bady and deliery was positive(r＝.4363, p＝.000, r＝.2881, p＝.012). No correlations between perceptions of labor and maternal-infant interaction were found(p＝0.062). 4. The daily maternal-infant interaction score for the initial contact after birth to 8 weeks postpartum had the lowest average score 5.20 and the highest 7.98(in a range of 0-10). This subjects group of mothers needed nursing intervention to promote their maternal- infant interaction. The daily scores for the maternal-infant over the period of eight weeks. However, there were significantly different increases in maternal-infant interaction only from the first to second day(p＝0.000) and from the fourth to sixth weeks after birth(P＝0.000). 5. When the eight items of maternal-infant interaction were evaluated separately, “Expresses feelings about her role as mother” had the highest average score, 1.64(ina range of 0-3)and “Speaks to baby” the lowest, 0.9. All items, with the possible exception of “Expresses feelings about her role as mother”, suggested the subjects' need of nursing intervention to promote maternal-infant interaction. 6. There were positive correlations between certain general charateristis, namely, both a higher economic status(p＝0.002) and breast feeding(p＝0.202) and maternal - infant interaction. There were positive correlations between a mother's confidence in her role as a mother and the perception of the birth experience(p＝0.004). For mothers who had a cesarean section, a positive perception of the birth experience was related to the duration of her marriage(p＝0.010), a wanted pregnancy (P＝0.030) and her confidence in her role as a mother(p＝0.000). Pereptions of birth for mothers who had a normal vaginal delivery were positive than those for mothers who had a cesarean section. The level of maternalinfant interaction for mothers delivered vaginally was higher than for cesarean section mothers. The relationship between perception of birth and materanalinfant interaction was confirmed. Cesarean section has an impact on the mother's perceived experience of birth which, in turn, is positively related to maternal-infant in turn, is positively related to maternal-infant interaction. Nursing intervention to enhance maternal-infant interaction should begin in prenatal classes with an exploration of the potential impact of cesarean section on the perceptions of the birth experience and continue throughout the perinatal and post-natal periods to promote the mother's ability to control with this crisis experience and to mobilize social support. Nursing should help transform a relatively negatively perceived experience into an accepted, positively perceived and self affirming experience which enhances the maternal-infant relationship.

연구목적 : 우울증 환자의 사회적 인지내용은 우울증을 치료하는 과정에서 치료목표가 될 수 있을 뿐만 아니라, 치료방법을 결정하는 초석이 된다. 또한 환자의 증상이 악화될 것인지 또는 재발할 것인지를 예측할 수 있는 좋은 지표이기도 하다. 그러나 우울증의 증상들을 평가하기 위한 척도와는 달리 아직 우리나라에서 사회적응성을 평가하기 위한 척도는 아직 소개된 바 없다. 이에 Bosc 등이 개발하였고, 유용성에 대해 이미 인정되어 있는 Social Adaptation Self-rating Scale(SASS)를 한국어로 번안한 척도에 대하여 신뢰도 및 타당도를 검증하였다. 방법 : SASS를 한국어로 번안하여 총 21문항으로 구성된 한국어판 사회적응 자기평가척도를 작성한 후 신체적, 정신적으로 건강한 정상인 291명과 우울증 환자 40명을 대상으로 시행하였다. 1) 한국어판 SASS의 신뢰도 검증결과 대상자 전원에 대한 Cronbach $\alpha$계수는 0.790. Spearman-Brown 반분신뢰도는 0.782(Guttman split-half=0.78) 이었다. 정상인 집단의 경우 Cronbach $\alpha$계수는 0.734. Spearman-Brown 반분 신뢰도는 0.619(Guttman split-ha1f=0.7318)였으며, 우울증 집단의 Cronbach $\alpha$계수는 0.8852. Spearman-Brown 반분신뢰도는 0.8852(Guttman split-half=0.8548) 이었다. 정상인 집단에서 45명을 대상으로 2주 간격으로 시행한 검사 재검사 신뢰도 검증결과는 r=0.653(p<0.01)으로서 비교적 시간적 안정성을 보였다. 2) 집단간 SASS 및 Purpsoe in Life(PIL) 검사 점수 차이의 검증에서 정상인집단의 SASS 총점 평균은 $40.12{\pm}5.27$, PIL 총점 평균은 $98.41{\pm}14.02$였고, 우울증 집단은 각각 $30.12{\pm}10.04$, $75.70{\pm}23.53$이였다. 두 점수 모두 우울증 집단에서 통계적으로 유의미하게 낮은 점수를 보였다(p<0.0l). SASS의 각 문항별 접수는 문항5, 문항 15, 문항 16, 문항 19를 제외하고 모든 항목에서 정상인 집단이 통계적으로 의미 있게 높은 점수를 나타냈다(p<0.0l). 3) 정상인 집단에서 SASS와 PIL간의 상관관계는 r=0.510으로서 통계적으로 의미 있는 상관관계를 나타냈다(p<0.0l). 우울증 집단의 경우 유병기간의 평균은 $52.17{\pm}83.86$개월로서 SASS, PIL, Beck's Depression Inventry(BDI) 및 우울증 이병기간과의 상관관계에서 SASS와 PIL는 정상인 집단과 마찬가지로 정적인(positive) 상관관계를 나타냈으나(r=.671), SASS와 BDI(r= -.609), PIL과 BDI(r= - .621) 척도간의 상관은 모두 통계적으로 의미 있는 부적인(negative) 상관을 나타내었다(p<0.01). 그러나 우울증의 이병기간과 SASS, PIL, BDI 척도간의 상관은 통계적으로 유의미한 상관을 나타내지 않았다(p>0.05). 4) SASS의 요인분석결과 정상인 집단의 경우 요인 1은 '사회활동'을 나타냈고, 요인 2는 '대인관계에 대한 적극성', 요인 3은 '자신감'을 나타냈다. 요인 4는 '외모의 중요성', 요인 5는 사회적응의 방법으로서 지적인 탐구'를 나타냈으며, 요인 6은 '사회활동에 대한 참여욕구'를 나타냈다. 우울증 집단에서는 요인 1에 SASS의 거의 모든 문항들이 해당되어 요인 1에 의한 단일 구조를 시사하였다. 요인 2는 '취미나 레저활동 욕구'가 관계되었다. 요인 3은 '가족 지향성', 요인 4, 5, 6은 '직업에 대한 흥미', '대인관계 추구', '의사소통 욕구'를 포함하고 있어 우울증 환자들이 사회적응상 가장 핵심적 문제들과 관계를 나타내었다. 결론 : 이상의 결과들로 보아 한국어판 SASS는 우울증의 사회적응성을 평가하기 위해 신뢰할 수 있고 타당한 척도라고 사료된다.
