이 논문은 기존의 포트폴리오와 관련된 모형에 경기변동(business cycle)과 관련된 변수들을 포함하였을 경우 경기변동이 개인투자자들의 현금 및 주식보유를 통한 자본이득 극대화와 어떤 관련성이 있는지와 관련된 것이다. 기존 문헌들을 살펴보면, 개인투자자들은 경기호황기에는 모멘텀 투자와 소형주와 성장주 등에 포트폴리오를 분산투자하지만 경기가 침체기(recession)에 들어설 경우 수익률이 급등락 하는 특성을 지니는 소형주(small cap)에 집중적인 투자를 하는 성향을 나타내고 있다. 한편 이 논문의 분석결과에 따르면, 경기안정과 금리안정정책, 물가안정 등은 서로 상충관계(trade-off)에 놓여 있음에도 불구하고 코스피 수익률과 코스닥수익률에 모두 향후 영향을 미칠 것으로 판단된다. 이는 현재까지의 정책조합(policy mix)보다 더 정교하고 타이밍을 잘 포착하지 않으면 정책실패에 따른 경기와 물가불안이 동시에 나타나는 스태그플레이션(stagflation)으로 이어질 수 있음으로 정책집행의 효율성이 어느 때보다도 중요해 질 것으로 보인다.

As information and communication technologies are being developed so rapidly, education research is actively conducted to provide optimal learning for each student using big data and artificial intelligence technology. In this study, using the mathematics learning data of elementary school 5th to 6th graders conducting blended mathematics classes, we tried to find out what factors predict mathematics academic achievement and developed an artificial intelligence model that predicts mathematics academic performance using the results. Math learning propensity, LMS data, and evaluation results of 205 elementary school students had analyzed with a random forest model. Confidence, anxiety, interest, self-management, and confidence in math learning strategy were included as mathematics learning disposition. The progress rate, number of learning times, and learning time of the e-learning site were collected as LMS data. For evaluation data, results of diagnostic test and unit test were used. As a result of the analysis it was found that the mathematics learning strategy was the most important factor in predicting low-achieving students among mathematics learning propensities. The LMS training data had a negligible effect on the prediction. This study suggests that an AI model can predict low-achieving students with learning data generated in a blended math class. In addition, it is expected that the results of the analysis will provide specific information for teachers to evaluate and give feedback to students.

This study is on the general characteristics of 'Monolithic' architecture. The intentions of monolithic architecture can be assumed as an attempt to replace the formal looseness or difficulties of understanding formal complexity of modern architecture, or a trial to react against contemporary avant-garde architectural tendency typically characterized as unstableness, uncertainty, fluidity, and articulation to reestablish autonomy of architecture. Buildings in this category coincide in their extreme economy and simplicity of overall form and consistency of external appearance while showing great expressional capacity with very limited formal means. Even though monolithic architecture still seems a little unstable and ambiguous in historical aspects, it can be considered as strikingly shaped objects or autonomous forms with identities, logics, and representation that promote recognition. Using architectural techniques of scale, colors, materials and finishes, monolithic architecture shows strategically invested surfaces that mediate between the inside and the outside, and shows unexpected and mysterious autonomy. This kind of monolithic approach is also found in interior space as a separate objects that contain functional space inside, or as formal elements that overflow the boundaries of conventional architecture by eliminating the distinction between floor, wall, and ceiling.

This study was conducted in order to explain the effect of driving behavior determinants such as drivers' personality and attitude that may induce risky driving behavior and to develop a valid method for discriminating risky drivers using the determinants. In the results of surveying 534 adult drivers, 5 driving behavior determinants (avoidance of problems, benefit/stimulus seeking, interpersonal anxiety, interpersonal anger, and aggression) were found to have a statistically significant effect on drivers' various risky driving behaviors. Using these factors, drivers were grouped according to risk levels (normal drivers, unintentionally risky drivers, and intentionally risky drivers). This result suggests that drivers' dangerous behavior level can be predicted using psychological factors such as their personality and attitude. Accordingly, if the driving behavior determinant model and the base score system used in this study are improved through further research, they are expected to be useful in predicting drivers' recklessness in advance, identifying problems, and providing differentiated safe driving education services based on the results.

The avoidance tendency of voice call in younger generation facilitates the growth of mobile O2O service that utilizes Messaging. This study adopted and elaborated original concepts of telephone apprehension to apply phone anxiety to O2O. We examined previous researches related to the ubiquity of service quality, communication ability and anxiety, and then conducted a survey to understand the consciousness of mobile O2O service users. The results show that users with high message intimacy and users with poor logicality are afraid of voice calls. The mobile O2O service is considered useful as a means to replace an unstable situation. In this study, we considered individual characteristics of acceptance factor of O2O mobile service technology, and it was a new attempt to expand telephone apprehension characteristic reflecting current situation. In addition, the different results of this research from prior studies that examined the relationships among apprehension, usefulness, and continuous use intentions might be helpful to expand and sophisticate the research area.

Objective : Obesity has been considered to be associated with numerous physical, mental and psychological diseases. Depression, which is a major psychological factor affecting occurrence and treatment of obesity, can be a cause of obesity as well as can be triggered by obesity. This study aimed to find out the need of positive consideration to the existence of depressive mood in the management of obesity. Methods : A total of 101 subjects were enrolled among those who were 60 years old and over at one local clinic. Obese group (n=49) was defined as BMI${\geqq}$25 and normal weight group (n=52) as 20$5.2{\pm}2.5$) was significantly higher than that of the normal weight group ($3.8{\pm}1.7$)(p<0.05). In male subjects, there was no significant difference in the mean GDSSF-K score between both groups, but in female subjects, the mean GDSSF-K score of the obese group, $6.4{\pm}2.6$ was significantly higher than that of the normal weight group ($4.0{\pm}1.8$)(p<0.05). Conclusion : The elderly obese group showed higher depressive scale score than elderly normal weight group, especially in female elderly. Since the elderly obese female group had a depressive predisposition, comprehensive management including mental and psychological approach is required in obesity control programs.

Background: Spirituality has been an important part of Transpersonal Psychology and is believed to have a large effect on the mental health because it has been systematized. The aim of this study was to determine the level of spiritual disposition on human beings along with its effects on one's mental health. Materials and Methods: The study targeted 400 women residing in Youn-Gil city of JiLin Prov., which is a district of the Cho-Sun tribe in China. Their spiritual well-being was studied using the Spiritual Well-being Scale-Korean Version. The spiritual well-being scale consists of 2 sub-scales of religious well-being and existential well-being. The study was evaluated using a lie scale, psychotic trend, and a combined anxiety-depression scale. The results were considered to be factors of one's mental health. The correlation between the spiritual well-being and each tendency was analyzed by regression analysis. Results: The total score of the Cho-Sun tribal women according to the spiritual well-being scale was 68.29 which was much less than the 100.65 of Korean Christian women. There was no significant correlation between the spiritual well-being and the Lie trend. However, it was found that 86%(344) of Cho-Sun tribal women scored above 70 in the Lie trend with a mean score of 74.57 which is higher than normal populations. Regarding the correlation between the spiritual well-being and psychotic trend, the psychotic trend became significantly higher when the religious well-being was at a high level. On the other hand, the psychotic trend became significantly lower when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and anxiety, the anxiety was significantly higher when the religious well-being was at a high level. However, the anxiety level was significantly low when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and depression, the depression level was somewhat significantly high when the religious well-being was at a high level. However, the depression level was significantly low when the existential well-being was at a high level. Conclusion: This study evaluated the effects of spiritual well-being on a person's mental health among Cho-Sun tribal women in Youn-Gil city of JiLIn Prov., P.R. of China. The results found that the religious well-being, which is a sub-scale of spiritual well-being, had negative effects while the existential well-being had positive effects on the mental health. These results proved that a person's religious disposition had negative effects on their mental health in a communitarian society.
