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.

Purpose: This study aimed to establish a basis for application time and cold therapy interval by checking the physiological changes after applying a cold-gel and ice pack, commonly applied to cold therapy, and after passive rewarming. Method: A total of 22 healthy adults used cold-gel packs and ice packs in a Randomized control group repeated measurement study, and passive rewarming was performed for 40 minutes after 30 minutes of cold therapy. After applying to the right axilla, StO₂, SpO₂, peripheral blood flow, skin and body temperature were measured 15 times every 5 minutes. Result: In the cold-gel pack group, StO₂ decreased from 69.43% to 61.06% after 30 minutes application, and in the ice pack group, StO₂ decreased from 67.66% to 64.80% (p <001). In the cold-gel pack group, skin temperature decreased from 33.57℃ to 29.15℃ after 30 minutes application, and in the ice pack group, skin temperature decreased from 32.64℃ to 28.90℃ (p <.001). Only skin temperature recovered completely after 40 minutes of rewarming. There were insignificant differences between the cold-gel pack and ice pack. Conclusion: When applying cold therapy to the axillary, at least 40 minutes for passive rewarming is necessary after 30 minutes of application.

In this study, C-Arm equipment is being used as we intend to verify the exposure dose on the operator by the scattering rays during the operation of the C-Arm equipment and to provide an effective method of reducing the exposure dose. Exposure dose is less than the Over Tube method utilizes the C-arm equipment Under Tube the scheme, The result showed that the exposure dose on the operator decreased with a thicker shield, and as the operator moved away from the center line. Moreover, as the research time prolongated, the exposure dose increased, and among the three affixed location of the dosimeter, the most exposure dose was measured at gonadal, then followed by chest and thyroid. However, in consideration of the relationship between the operator and the patient, the distance cannot be increased infinitely and the research time cannot be decreased infinitely in order to reduce the exposure dose. Therefore, by changing the thickness of the radiation shield, the exposure dose on the operator was able to be reduced. If you are using a C-Arm equipment discomfort during surgery because the grounds that the procedure is neglected and close to the dose of radiation shielding made can only increase. Because a separate control room cannot be used for the C-Arm equipment due to its characteristic, the exposure dose on the operator needs to be reduced by reinforcing the shield through an appropriate thickness of radiation shield devices, such as apron, etc. during a treatment.
