본 연구는 전 세계 온라인 게임시장 1위를 차지하고 있는 ‘Riot game’의 <League of Legends>의 게임성에 대한 사용성 평가를 통해 사용자들이 흥미를 유발하는 요인들을 알아보고 향후 국내 후발업체인 ‘NEOWIZ’의 <카오스온라인>의 업데이트 및 국산 AOS게임개발에 필요한 사항들을 제안하는데 그 목적을 두었다. 연구 방법으로는 첫 번째, 문헌연구를 통하여 현재 전 세계 온라인 게임시장의 동향과 전망을 살펴보고, 국산 AOS장르 게임개발을 통한 해결책을 모색하였다. 두 번째, AOS장르를 주로 즐기는 사용자들을 대상으로 정량적 평가를 위한 사용성 평가를 실시했다. 이때 사용성 평가의 도구로는 피터모빌(Peter Morville)이 정의한 ‘The User Experience Honeycomb’을 바탕으로 39문항의 설문지를 작성하였다. 이를 통하여 AOS게임을 평소에도 즐겨왔던 대상 중 총 84명을 선발하여 설문조사를 실시하였으며 표준오차를 줄이고 신뢰도를 높이기 위하여 기술통계 및 사용자별 기술통계를 도출하였다. 이러한 통계자료는 각각 가치별 기준 배점표에 적용하여 다음과 같이 결과를 도출하였다. 첫째, 게임 시스템 인터페이스 및 설정 메뉴는 사용자가 쉽게 설정할 수 있는 기본메뉴와 전문 사용자를 위한 고급메뉴를 별도로 제직하여야한다. 둘째, 대한민국에 AOS게임 수요자가 현저히 증가하였고, 충성도가 높기 때문에 향후 새로운 AOS게임개발은 충분한 경쟁력을 가지고 있으며 시급히 개발되어야한다. 셋째, 비신사적인 행동에 대한 엄격한 룰이 존재해야 한다. 넷째, 텍스트형 채팅시스템이 아닌 사용자간의 음성채팅시스템을 자체 게임시스템 내에서 직접 제공하여야한다. 다섯째, 캐릭터의 형태, 목소리, 모션 사운드 등을 바꾸는 스킨뿐만이 아닌 다른 수익모델을 개발해야한다. 단 현금아이템이 게임플레이에 영향을 주면 안 된다. 이를 통하여 본 연구는 새로운 국산 AOS게임 개발은 물론 나아가 국산 온라인게임시장의 새로운 장르 다각화에도 기여를 할 수 있다고 기대된다. The purpose of the study is to evaluate the usability of AOS on-line games mainly on League of legends and Chaos online. We also make suggestions on how to improve AOS game user experience(UX) through League of legends usability test for Game Characteristic. To achieve accurate results, we first gathered information of the global on-line game market and problem of The Korea on-line game market. Then we conducted quantitative survey to evaluate usability of AOS. To reduce sampling error, we surveyed 89 adults on October and we presented descriptive statistics for the reliability of the results of a survey. After analyzing results of this user experience test, we propose the following. Firstly, game setting menus must be devided to basic menu and advanced menu. Secondly, since AOS genre is promising in the global market, Korea game companies urgently have to develop AOS games. Thirdly, there must exist strict rules about trolling. Lastly, user to user voice chat system must be provided instead of text chat system as well as attractive paid items.

쌀 전분에 propylene oxide(PO)를 단계별(전분 공형분 대비 2-12%)로 20시간과 24시간 반응시켜 하이드록시프로필화 쌀 전분을 제조하고, 변성된 쌀 전분의 용해도, 팽윤력, RVA, DSC 특성을 연구하였다. 팽윤력은 일반 쌀 전분 보다 낮은 온도에서 증가되기 시작하였으나 높은 경향을 보였으며, 하이드록시프로필화 쌀 전분이 일반 쌀 전분보다 완만한 상승을 나타내었다. 용해도는 하이드록시프로필화 쌀 전분이 일반 쌀 전분보다 낮은 결과를 나타내었고 PO 함량이 높을수록 높아지는 결과를 보였다. RVA 분석결과 PO 함량이 높을수록 pasting temperature와 peak time이 낮아졌고 최고 점도는 하이드록시프로필화 쌀 전분이 일반 쌀 전분보다 낮고 holding strength는 높은 경향을 나타내고 breakdown의 경우 반응시간이 24시간이 20시간보다 낮은 경향을 보였으며 Setback은 24시간 반응시킨 처리구들이 일반 쌀 전분보다 낮은 것으로 나타났다. DSC분석결과 PO 함량이 높을수록 To, Tp, Tc, ${\Dalta}H$가 감소하였다. 따라서 하이드록시프로필화 쌀 전분의 경우 전분입자내의 intemal bond가 하이드록시프로필기에 의해 약해져서 호화가 쉽게, 즉 낮은 온도에서 일어나는 것으로 판단되었고 최대 팽윤력, breakdown에서 옥수수 전분과는 다른 결과를 나타내어 전분의 종류에 따라 같은 변성 처리라고 하더라도 다른 결과를 나타낼 수 있다는 사실이 확인되었다. Physicochemical properties of hydroxypropylated rice starches were investigated. Swelling power of hydroxypropylated rice starch increased at relatively lower temperature than native rice starch. Solubility of hydroxypropylated rice starch was lower (1.9-13.4%) than that of native rice starch (2.2-13.8%), and increased with increasing amount of propylene oxide. Pasting temperature ($66.2-70.8^{\circ}C$) and peak viscosity (2,843-3,395cp) of hydroxypropylated rice starch were lower than those of native starch ($71.6^{\circ}C,\;3,976\;cp$) and decreased with increasing amount of propylene oxide, regardless of reaction time. DSC thermal transitions of hydroxypropylated rice starches shifted toward lower temperature. Amylopectin-melting enthalpy of hydroxypropylated rice starch decreased (11.8-9.8J/g) with increasing amount of propylene oxide and was lower than that of native starch (11.9 J/g). These results indicate hydroxypropylation lowered swelling power and gelatinization temperatures of rice starch, because internal bonds of rice starch molecules were sterically weaken by substituted hydroxypropyl groups.

Background: Blunt thoracic trauma in children has a high morbidity and mortality. In this study, we assessed the significance of the injury pattern, mechanism and initial status in emergency department on severity and prognosis in pediatric blunt thoracic trauma patients. Method: We retrospectively reviewed medical records and chest X-ray and CT images of 111 pediatric blunt thoracic trauma patients from October 2000 to June 2005. Data recorded age, gender, season, injury mechanism, injury pattern, associated injury, length of hospital stay and cause of death. Result: Of all 111 patients, 68 patients were injured by motor vehicle accidents, 30 were falls, 5 were motorcycle accidents, 3 were sports accidents and 5 were miscellaneous. In thoracic trauma, single injury of lung contusion were 35 patients and 32 patients had multiple thoracic injuries. Hospital stay in school age group were longer than preschool age group. The causes of death were brain injury in 9, respiratory distress in 4, and hypovolemic shock in 2 patients. Emergently transfused and mechanically ventilated patients had higher mortality rates than other patients. Patients required emergency operation and patients with multiple thoracic injuries had higher mortality rates. Conclusion: In this study, patients with combined injury, emergency transfusion, mechanical ventilation, emergency operation, multiple injuries in chest X-ray had higher mortality rates. Therefore in these pediatric blunt thoracic trauma patients, accurate initial diagnosis and proper management is required.

We present a retrospective study on the characteristics of head injury in the aged (more than 60 years of age). We selected 107 patients who visited the Chung Ang Gil Hospital due to head injury from January 1994 to December 1994. For comparison, data from 598 patients who were less than 60 years of age during same study period was used. In the aged, pedestrian traffic accident, slip or fall, and unknown trauma were common as a cause of head injury. The rate of intracranial mass lesion was higer in the aged. Contusional hemorrhage and subdural hematoma were common in the aged, while epidural hemotoma was the most common lesion in the young. The frequency of delayed lesion and intracranial mass lesion without skull fracture were more common in the aged. The rate of operative treatment and the mortality rate of the aged were higher than those of the young. This study revealed that the cause of head injury in the aged was different from that of the young, and the rates of intracranial mass lesion and de-layed lesion were higher in the aged, which increased the proportion of the patients with low GCS, and made the prognosis of the aged poor.

It has been known that sternal fracture increases the risk of potentially life-threatening injuries, such as myocardial, pulmonary, and thoracic vascular injuries, and it has 25% to 45% of mortality, primarily resulting from these underlying injuries. The authors reviewed retrospectively the medical records and radiographic findings of the patients who admitted with sternal fracture at Chung Ang Gil Hospital from 1 June 1994 to 31 December 1995 to evaluate the significance and clinical course of sternal fracture. The results were followings: 1. The male to female ratio was 3:2 and the mean age was 43.1 and 45.4 years old in male and female, respectively. 2. Motor vehicle occupant accident was the most common cause of sternal fracture. 3. Of 33 cases, there was no death, but common associated injuries which were rib fracture, hemothorax, lung contusion, vertebral fracture, penumothorax, long bone fracture, myocardial contusion, flail chest, facial chest, facial bone fracture, and pericardial effusion, in order. 4. The clinical course of sternal fracture was determined primarily by associated injuries except for communited sternal fracture. 5. The patients with isolated sternal fracture, who had an otherwise normal chest x-ray, normal electrocardiogram, no other significant associated injuries and are hemodynamically stable, had a benign clinical course.

The capsaicinoids of Korean red peppers were varied with cultivars from 30 mg% to 257mg%, highest in ˝Chungyang˝and medium in ˝Dabock˝ which is most popular to Korean and major capsicinoids were capsaicin and dihydrocapsaicin which are 88.5-94.8% of total capsaicinoids in red peppers. The capsaicinoids of red pepper were distributed 46% in placenta and septum and remainder were in pericarp, seed and stem in the order. The changes in capsaicinoids content of red peppers was not significant during hot-air drying at 65-75℃and sun drying. Fluorescent light was more destructive to capsaicinoids than incandescent light when red pepper powder was exposed to those lights. The larger amount of capsaicinoids was extracted with higher concentration of salt solution, but the water extractability was not affected by pH changes. During storage at 4,25,40℃ for 180 days, capsaicinoids content of red peppers was changed.

우리나라 전통차의 제조기술 개발과 품질향상을 위한 기초연구로서 국내에서 생산되는 주요 다류(쌍화차, 생강차, 율무차, 현미차, 유자차, 홍차, 녹차) 7종에 대한 관능적 품질특성을 조사하였다. 다류의 관능평가를 위한 표준방법을 수립하기 위하여 50명의 대학생을 대상으로 하여 차종류에 따라 마시기에 가장 알맞은 온도범위를 조사하였든 바, 7종의 다류 모두 60℃-70℃ 범위가 최적 음다 온도로 나타났다. 최적온도는 일반적으로 다류 제조회사가 권장하는 농도가 적당한 것으로 평가되었다. 차종류에 따른 품질묘사는 주로 맛, 냄새, 입속의 감촉, 뒷맛 등에 대한 표현이 45종이 조사되었다. 이들 결과를 기초로 하여 8명의 훈련된 관능검사요원으로 구성된 관능검사파넬을 이용하여 차종류별 풍미묘사분석(flavor profile analysis)을 실시하였다. 차종류별 주요 풍미요소를 정리하여 풍미묘사분석방법을 수립하였고 차종류별 대표적인 시중제품과 순수한 추출물 및 원료들을 시료로 하여 총 29종의 flavor profile을 비교하였다. 이들 결과를 정량적 묘사분석법으로 도해하여 비교 분석하였다. The sensory quality characteristics of 7 different types of Korean traditional tea products were analyzed. For the standardization of sensory testing condition, the optimum drinking temperature were measured with 50 students, and all the samples tested were found to fall in the range of 60-70℃. The optimum concentrations of tea for drinking were generally met with the amount recommended by the producer. A total of 45 sensory describing terms expressing the taste, odor, and mouthfeel were collected. Using the sensory describing terms as the character notes, flavor profile analysis was made for each tea product with 8 members of trained panel. The differences in quality characteristics of 29 test samples were evaluated and shown in the chart constructed by the quantitative descriptive analysis method.
