This study was planned to develop an Internet Game Addiction Scale for 9- to 12-year-old Korean children. Based on literature review and analysis of counseling cases, the concept of the internet game addiction was defined. Items of the scale were developed and then the content validity of the scale was examined by 20 professionals. Then a preliminary survey of 188 3rd to 6th grade students was made, and the main survey of 699 3rd to 6th grade students throughout Korea. The main results are as follows; [I] Internet Game Addiction Scale consists of 3 factors with 20 items : game-oriented life(6 items), tolerance & mastery loss(7 items), and withdrawal & emotional experience(7 items); [II] appropriateness of item mean and standard deviation was proved, a 3-factor structure confirmed through factorial analysis and cross validation; [III] appropriateness of the scale confirmed through criterion validity and reliability.

A suitable culture method and bioreactor type for itaconic acid production were chosen by comparing the maximal concentration of itaconic acid produced in various systems. In batch culture, the maximal concentration of itaconic acid produced in a bubble column reactor was about 5% greater than that produced in stirred-tank or external-loop airlift reactor. These results were thought to be due to lower shear force and higher mass transfer efficiency in a bubble column reactor in comparison with other reactors. Moreover, the fed-batch mode in a bubble column was found to be a suitable one, producing about 25% higher concentration of itaconic acid compared to batch mode.

In this study, we examined the relationship among Multiple Intelligence constructs and the relationship among the sub-areas and analysed the development of the Multiple Intelligence according to age and gender to evaluate Korean children's Multiple Intelligence structures that teachers evaluated based on MIDAS-MYC. The subjects of the study consisted of 158 4-5 year old children (71 4-year-old group(boy 38, girl 33); 87 5-year-old group(boy 40, girl 47)) in Seoul and Gyeonggi. We found several results which are as follows. 1) Reliability on each area of intelligence in MIDAS-MYC was good. 2) The result of confirmatory factor analysis using the model of structural equation modeling was consistent with the results of other studies that children's Multiple Intelligence consists of eight intelligent areas that are independent to each other but are relative to each other. In particular, interpersonal-intrapersonal intelligence, languistic-intrapersonal intelligence, languistic-Interpersonal intelligence, and languistic-logic/math intelligence were high correlation. However, physical/motion-naturalist intelligence and musical-logic/math intelligence were low correlation. 3) Children's multiple intelligence differed according to age and sex, the 5-year-old was higher than 4-year-old and girls were higher than boys in a general way. 4) There was high correlation between the result of evaluation based on MIDAS-MYC and the result of teacher's subjective evaluation about children's Multiple Intelligence.

According to Formalist theory, form is not separate from content. Form does not merely convey or express content but can itself produce meaning. The close correlation of the narrative structure, more specifically the time structure of the narrative, and the narrative style of Kim Seung-Ok′s short story′"Travel in Mujin" provides a good example of this argument. The story opens with the first-person narrator, currently living in the bustling city of Seoul, back in his small provincial home town Mujin, where he brings up memories that had been hitherto suppressed. The revived memories are ordered into the narrator′s present thought structure, in effect bridging the vast psychological rift between the lost past and the present. The narrator′s travel in Mujin thus becomes a psychological journey, and Mujin becomes a psychological space where the narrator can experience the continuity of his own being. The "narrating I" excludes the principles of reality from his narrative, concentrating on the inner thoughts, recollections, psychological experience, and the level of consciousness of the "narrated I." This narrative attitude or style expresses the narrator-protagonist′s acceptance and affirmation of the thoughts and actions occur in Mujin (which he had till now been resistant to). It is also an affirmation of the narrative act itself. Before the travel back to Mujin, the narrator-protagonist′s thoughts about his home town was ambivalent-an attitude originating from nostalgia, together with the narrator-protagonist′s ambivalent attitude toward his youthful past. It is a reflection of the narrator-protagonist′s desire for purity intermingled with a disdain for his enervated existence in Seoul. This ambivalence is resolved by the "I" of the narrative present, and Mujin enables him to come to a renewed affirmation of his life.

목적: 본 연구는 국소적 냉 요법 중 가장 일반적으로 적용하는 냉 젤 팩과 얼음 팩을 적용 한 후와 수동적 재가온 후의 생리적 변화를 확인하여 냉 요법의 적용시간과 간격에 대한 근거를 마련하고자 합니다. 방법: 무작위 비교군 반복측정 실험연구로 건강한 성인 22명을 냉 젤 팩과 얼음 팩 그룹에 무작위 배정하여 30분 동안 냉요법을 적용한 후 40분 동안 수동 재가온을 실시했습니다. 오른쪽 액와에 냉요법이 적용되는 동안 5분 간격으로 총 15회, 조직과 말초의 산소포화도, 말초혈류, 피부온도, 체온을 측정하였습니다. 결과: 냉 젤 팩 군에서 StO₂는 냉 요법 전 69.43%였고, 냉 젤 팩 적용 30분 후 61.06% 였으며 얼음 팩 군에서 StO₂는 냉 요법 전 67.66%였고, 얼음 팩 적용 30분 후 64.80%로 크게 줄었습니다.(p <.001) 냉 젤 팩 군에서 피부온도는 냉 요법 전 33.57℃였고, 냉 젤 팩 적용 30분 후 29.15℃ 였으며 얼음 팩 군에서 피부온도는 냉 요법 전 32.64℃였고, 얼음 팩 적용 30분 후 28.90℃로 크게 줄었습니다.(p <.001) 40분 재가온 후에는 피부 온도만이 완전히 회복되었습다. 냉 젤 팩과 얼음 팩 그룹 간에는 큰 차이가 없었습니다. 결론: 액와에 국소적 냉 요법을 적용할 때는 30분 적용 후 적어도 40분 이상의 수동적 재가온을 위한 시간을 갖도록 해야 할 것입니다.

C-arm장비의 사용 시 시술자의 산란선에 의한 피폭선량을 확인하여 적절하고 효율적인 피폭선량 저 감화 방법을 알아보기 위해 본 연구를 진행하였다. Over Tube 방식에 비해 피폭선량이 적다는 Under Tube 방식의 C-arm 장비를 활용하여 연구한 결과 차폐도구가 두꺼울수록 시술자의 피폭선량은 감소하였고, 중심선에서 멀어질수록 피폭선량이 감소하였고, 조사시간이 길어질수록 피폭선량이 증가하였고, 세 곳의 선량계 부착위치 중 생식선에서 가장 많은 피폭선량이 측정되었고 흉부, 갑상선 순이었다. 그러나 실제 시술 중 피폭선량을 줄이기 위해 거리를 무한정 늘릴 수 없고, 조사시간을 무한정 단축시킬 수 없기 때문에 인위적으로 조절 가능한 차폐 두께를 달리하는 방법으로 시술자의 피폭선량을 감소시킬 수 있었다. C-arm장비를 사용할 경우 시술 중 불편하다는 이유로 방사선 차폐에 소홀히 하고 근접시술이 이루어지기 때문에 피폭량은 증가할 수밖에 없다. 이에 C-Arm장비의 특성상 조정실을 구비할 수 없으므로 Apron 등의 방사선 차폐도구의 적정두께 사용 등으로 시술 중 발생되는 방사선에 의한 시술자의 피폭선량을 경감시켜야 할 것으로 사료된다.
