This study is intended to review the war and the living of the common people of Choseon dynasty, through the true stories of captives kidnapped in the region of the Qing(胡地) during the Pyeongja horan in the 17th century. The common people, Kim seung kyung and Ahn chu won, who had been kidnapped in their young age, managed to escape from the region of the Qing to Choseon after having experienced a painful living as a captive for 27 years. Kim seung kyung and Ahn chu won had to make a choice to run away from the Qing in order to bring their war distorted life back to its original state. Kim seung kyung who had successfully escaped, could live without severe difficulties by the aid of his family living at his hometown, but Ahn chu won who had not found his own family or relatives, couldn't have got any helping hand from the people mentally or financially. So, he tried to escape again to Beijing, but discovered and captured so that a diplomatic problem was caused between the Choseon and the Qing Dynasty. Through the true story of Kim seung kyung and Ahn chu won, we can see the lives of Choseon common people who were trying to overcome the difficulties with their own iron will without being undaunted by hardships. Even though the captives had terrible experiences hating to remember, their experiences gave a chance to the Choseon people opening their eyes to the foreign cultures and the new world. At that time, the Choseon government was too weak to estimate how many captives were or what the captive's real fact was. Meanwhile the Choseon government managed to do the least duty in order to protect its people, by breaking the provisions of repatriation that the fled captives should be returned back to the Qing Dynasty. Through reviewing the captive's true story of the Choseon common people, we can ruminate the Choseon society in the 17th century which failed to establish an independent national history, and the issue of the Korean War captives in the modern history forgotten under the shade of the dustbin of history.

This study focused on the temperament of infants and on maternal sensitivity in the investigation of the factors which affect infant-mother attachment. The 67 infant-mother pairs were divided into two groups on the basis of attachment security scores. Results showed a relationship between infant-mother attachment and temperament. There was also a relationship between maternal sensitivity and infant temperament. Factors most strongly affecting infant-mother attachment were infant's sociability, mother's emotion, and mother's satisfaction with the degree of infant's sociability.

This study focuses on visual aesthetic factors in the apparel web site design. 103 undergraduates participated in the evaluation of six internet web sites. The evaluation were recorded and analyzed by using the inspection method and a questionnaire. Findings of this study can be summarized as follows: First, the result of SPSS-factor analysis shows that there are 2 distinct factors; 'classical aesthetics' and 'expressive aesthetics'. 'classical aesthetics' and 'expressive aesthetics' can be described by visual aesthetic design. This conceptual confusion relating to 'visual aesthetic design' can be clarified by these findings. Second, as a result of multiple regression analyses, 'classical aesthetics' and 'expressive aesthetics' have a positive influence on 'interactivity' and 'web site evaluation'. This research clarifies the concepts of 'engagement' of Rosen & Purinton as the 'interactivity' between users and web sites. Finally, this study suggests that 'good design' for internet web sites depends on understanding how to attain the appropriate balance between 'classical aesthetics' and 'expressive aesthetics', based on the target customer.

The purpose of this study was to demonstrate the paths among the risk-protective factors that related to the resilience based on the Challenge Model. The subjects for this study were 209 children from divorced families in the 4th, 5th, and 6th grades of elementary schools in Seoul and Gyunggi-do. As the results, there were 28 paths which affected the resilience of children from divorced families based on the Challenge Model. The protective factors were easy temperament, problem-focused coping style, parental support, peer's support, higher socio-economic status, experiences in therapy, presence of siblings, contact with adult caretakers. The risk factors were higher grade, emotion-focused coping style, and children's gender, especially girls. This result demonstrated that each risk and protective factor not only affected resilience separately but interacted with one another.

A cyclone is a dust-separating mechanism that works on the principle of centrifugal force. The performance of a cyclone is evaluated using pressure loss and collection efficiency. A multi-cyclone arrangement is used to improve the collection efficiency within a limited area. In this study, experiments and numerical analyses were conducted on a dual arrangement of mini-hydrocyclone separators, which was fabricated using 3D printing. The experiment was performed at an inlet flow rate of 0.7 m/s, and alumina powder with a particle size of 0.5, 15, and 50 ㎛. ANSYS FLUENT, was used for the numerical analysis. The reliability of the numerical analysis was verified through a comparison with the experimental results. The errors in the experiment and numerical analysis were confirmed to be 2% at the outlet flow rate.

Experiments were conducted to investigate the effect of light shading around the heading stage on grain yield and its components of rice. Early, medium, and late-maturing varieties were trected with the light shading of 50% and 75% from the reduction division stage to 20 days after heading date. Heading date were delayed 2-3 days, whereas the mid -late varieties, Sangpung- byeo, and Bongkwang- byeo were no significantly affected. Culm length was increased and panicle exsersion was reduced as the shading treatments become higher, and the degree of the shading effect was more intensive at 75% of shading. The rate of spikllet degeneration was higher at the secondary rachis branches than the primary rachis branch. The early maturing varieties showed the higher rate of spikelet degeneration. Spikelet number was reduced 12-15, spikelet sterility was increased and ripening rate was declined by the shading treatments. Grain yield was decreased by 30-40% at the shading treatment of 50%, and 50% at the shade treatment of 75%.

Intussusception primarily occurs in children and is uncommon in adults. Moreover, intussusception caused by intestinal tuberculosis is very rare. We report a case of intussusception induced by intestinal tuberculosis. A 53-year-old man presented to our hospital with complaints of cough and sputum for 2 weeks. We started anti-tuberculosis medication as the patient's sputum acid-fast staining was positive. After 4 days of treatment, the patient developed abdominal cramping pain. Imaging studies showed ileo-ileal type intussusception. The patient underwent segmental resection of the small bowel and intestinal tuberculosis was confirmed on histological examination. He recovered after surgery and was discharged on anti-tuberculosis medication.

A survey was carried out on the cold-induced sterility of paddy rice in 1988 in the alpine area of Kangweon province when cold spell occurred during late July to early August, During this period minimum temperature as low as 8.5$^{\circ}C$ and 5.7$^{\circ}C$ was recorded at Dunnae and Jinbu, respectively. The rice cultivars, which encountered this cold spe]J at meiotic stage of microspore, were damaged by sterility in most alpine areas of higher than 300m in altitude. To secure spilkelet fertility higher than 80% it was estimated that the minimum and average air temperature accumulated during 13 days of meiotic stage should be higher than 2$25^{\circ}C$ and 285$^{\circ}C$, respectively and/or the duration of lower than 17$^{\circ}C$ in minimum temperature should not exceed fivedays during that period.

As a first step for improvement of breeding and productivity of Epimedii Herba, the patterns of components and the difference in icariin, a main component of this plant, in compliance with seasons and places of collection were evaluated by HPLC. As a result, the patterns of components in samples collected in July-September were shown to be markedly increased compared to those collected in May. Corresponding to the alternations of the pattern, the amount of icariin, which was estimated to be 0.017% in May was found to be increased markedly up to 0.82% in September. The samples collected at Chul-won district showed the highest icariin contents (0.94%), however, those collected in China was only 50% level (0.4%) of domestic ones. These results strongly suggest that the quality of Epimedii Herba might be quite different with respect to the seasons and places of the collection.
