One of the long-standing problems in modern astronomy is the curious division of globular clusters (GCs) into two groups, according to the mean period (<$P_{ab}$>) of type ab RR Lyrae variables. In light of the recent discovery of multiple populations in GCs, we suggest a new model explaining the origin of the Sandage period-shift and the difference in mean period of type ab RR Lyrae variables between the two Oosterhoff groups. In our models, the instability strip in the metal-poor group II clusters, such as M15, is populated by second generation stars (G2) with enhanced helium and CNO abundances, while the RR Lyraes in the relatively metal-rich group I clusters like M3 are mostly produced by first generation stars (G1) without these enhancements. This population shift within the instability strip with metallicity can create the observed period-shift between the two groups, since both helium and CNO abundances play a role in increasing the period of RR Lyrae variables. The presence of more metal-rich clusters having Oosterhoff-intermediate characteristics, such as NGC 1851, as well as of most metal-rich clusters having RR Lyraes with the longest periods (group III) can also be reproduced, as more helium-rich third and later generations of stars (G3) penetrate into the instability strip with further increase in metallicity. Therefore, although there are systems where the suggested population shift cannot be a viable explanation, for the most general cases, our models predict that RR Lyraes are produced mostly by G1, G2, and G3, respectively, for the Oosterhoff groups I, II, and III.

This is a case study trying to understand from the view of affordance which certain three middle school students perceive an activation of previous knowledge in the course of problem solving when they solve algebra word problems with a previous knowledge. The results of this study showed that at first, every subjects perceived the text as affordance which explaining superficial similarities, that is, a working(painting)situation rather than problem structure and then activated the related solution knowledge on the ground of the experience of previous problem solving which is similar to current situation. The subject's applying process for solving knowledge could be arranged largely into two types. The first type is a numeral information connected with the described problem situation or a symbolic representation of mathematical meaning which are the transformed solution applied process with a suitable solution formula to the current problem. This process achieved by constructing a virtual mental model that indicating mathematical situation about the problem when the solver read the problem integrating symbolized information from the described text. The second type is a case that those subjects symbolizing a formal mathematical concept which is not connected with the problem situation about the described numeral information from the applied problem or the text of mathematical meaning, which process is the case to perceive superficial phrases or words that described from the problem as affordance and then applied previously used algorithmatical formula as it was. In conclusion, on the ground of the results of this case study, it is guessed that many students put only algorithmatical knowledge in their memories through previous experiences of problem solving, and the memories are connected with the particular phrases described from the problems. And it is also recognizable when the reflection process which is the last step of problem solving carried out in the process of understanding the problem and making a plan showed the most successful in problem solving.

This study was designed to identify how customers considered menu selection attributes on menu choice, and so the instrument for measuring that question was developed and menu selection behavior types were analyzed by customers' characteristics. Cronbach's alpha to assess the internal reliability of the developed scales was 0.8361, which indicated to be highly reliable. Construct validity was assessed by principal components factor analysis with a Varimax rotation to identify underlying dimensions of menu selection and then four factors explaining 55.618% of the total variance were found. These factors were labeled as 'quality of meals', 'attractiveness of meals', 'healthfulness of meals' and 'variety of meals', respectively. As a result of analysis on menu selection factors, 'quality of meals'(3.82 out of 5) was the highest consideration followed by 'variety of meals'(3.51), 'healthfulness of meals'(3.49) and 'attractiveness of meals'(3.34), so that menu marketing approaches in the perspective of quality of meals would do lead customers' selection rates, customer satisfaction and then sales highly. Frequent visitor selected menu indifferently but customers who were interested in food and menu highly, who perceived meals' quality highly, and who were satisfied with overall foodservice did with concern. On the basis of these results of study for the target of food court-style B ＆ I foodservice operation, which was introduced as an ideal model in future foodservice market by the concept of 'customer's selection right', the following study related with customers' meal patterns and perception of foodservice by menu selection attributes would be able to predict the chances for success of food court-style foodservice operations.

In Korean Traditional Medicine(K.T.M.)'s theory, there are some important constitutions which constitute the human being. They are Jeong(精), Gi(氣), Sin(神), and Hyeol(血). Jeong(精) is the essential substances which constituting human body and maintaining life's activities. Gi(氣) is the vital energyor functional activities of human body. Sin(神) is a kind of Gi(氣) which is related to mentality, consciousness and thinking. Hyeol(血) is the red fluid circulating through the blood vessels and nourishing the body tissues. When a man is born, he takes Jeong(精) from his father, and Hyeol(血) from his mother. So father' s Jeong(精) and mother' s Hyeol(血) became the source of their children's Jeong(精), Gi(氣), Sin(神), Hyeol(血). But after be borning, man need to make Jeong(精), Gi(氣), Sin(神), Hyeol(血) by himself from Foods and drinks[水穀]. This thesis was written to explain a process or a system how the Foods and drinks[水穀] change to human's Jeong(精), Gi( 氣), Sin(神), Hyeol(血). When the food and drink[水穀] put in human's mouth, Five Bu[五腑] primarily digest and change to food and drink[水穀]'s Essence and nutrients which is similar to chyme or chyle[乳廳]. Secondarily, Five Jang[五臟] make Gi(氣), Jinaek(津液) - the body fluid, Jeong(精), Wigi(衛氣) - the defensive Gi, and Yeonggi(營氣) - the nutrient Gi circulating the Meridians, and Hyeol(血) from that food and drink [水穀]'s Essence and nutrients. And the information of every processing is reflected in urine. 50 the digestion is accomplished at not only Five Bu[五腑] but also five Jang[五臟]. The concept of digestion in this thesis is including both catabolim[異化作用] and anabolism [同化作用]. Samcho(三焦) is the recognition to the process of this digestion - ctabolism and anabolism in three part.

Purpose: Purpose of this study was to investigate relationships and influence of peripheral neuropathy, sleep, and quality of life in patients with gastric cancer who are receiving chemotherapy. Methods: Participants were 131 patients with gastric cancer being treated at a chemotherapy outpatient clinic and receiving chemotherapy. Data were analyzed using descriptive statistics, t-test, ANOVA, and multiple regression analysis with the SPSS program. Results: Mean score for peripheral neuropathy was 24.66, for sleep, 6.71 and for quality of life, 67.69. Peripheral neuropathy had a significant positive correlation with sleep (r=.26, p=.003) and sleep had a significant negative correlation with quality of life (r=-.50, p<.001). The regression model explaining quality of patients'lives was significant (F=11.91, p<.001), peripheral neuropathy, sleep, and pain due to anticancer drugs and number ofneurotoxic anticancer drugs explained 25.1% of the variance in quality of life and sleep was the most important factor. Conclusion: To improve the quality of life for these patients, individualized nursing interventions for pain should be provided according to number of anticancer drugs in the chemotherapy. Also there is a need to identify ways to assess peripheral neuropathy and sleep disorders that are appropriate in the treatment and reduce side effects during treatment.

Objective : This study aims to identify personality characteristics in female homicide offenders by using the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) test. Methods : This study retrospectively analyzed the mental appraisals and MMPI-2 scores of 54 women charged with homicide and 67 women charged with non-violent crimes, who were referred to National Forensic Hospital in Gongju city for psychiatric evaluation between January 2012 and March 2016. Results : Women charged with homicide scored significantly higher on Hs (p=0.018), D (p<0.001), Hy (p=0.002) and Pt (p=0.004) than the women charged with non-violent crimes. The women charged with homicide may have developed the following characteristics: hypochondriasis, depression, hysteria and psychasthenia. In multiple regression analyses, a final regression model including age of crime onset and depression was significant, explaining 16.5% of the variance in homicides committed by females. Conclusion : These findings suggest that personality characteristics in the female homicide offenders might be different compared to the non-violent crime offenders.

본 연구는 최근 글로벌 외환시장에서 첨예하게 대립하고 있는 환율갈등의 요인을 분석하기 위해 국가간 실질 및 명목이자율 차이가 환율결정에 미치는 영향을 분석하였다. 유위험, 무위험, 및 실질이자율평가의 실증분석 결과를 종합해 보면 유위험이자율평가가 다른 두 경우보다, 실질이자율평가가 무위험이자율평가 보다 환율결정에 더욱 영향을 미치기는 하지만 그 정도는 충분히 크지 않은 것으로 분석되었다. 또한, 국가간 환율결정에 실질이자율평가가 성립되지 못하는 원인을 규명하기 위해 국가할증, 환율변동위험 할증, 및 통화할증을 분석하였는데, 그 결과에 의하면 국가할증과 환율변동위험 할증이 실질이자율평가의 성립을 어렵게 하는 요인으로 분석되었다. 실증분석 결과를 종합해 볼 때 최근의 국가간 환율갈등의 원인은 외환위기 이후 글로벌 외환시장에서 환율이 각국의 경제력을 바탕으로 결정되기 보다는 시장의 외부요인인 전략에 의해 영향을 받았기 때문인 것으로 보인다. 따라서 환율갈등을 완화 또는 근본적으로 해결하기 위해서는 각국의 외환정책 당국은 시장지향적이고 시장결정적인 환율제도를 구축하여야 할 것이다.
