Objectives: The aim of this study is to investigate clinical effects of Chuna treatment on the neck pain patient with hypolordotic cervical spine. Methods: From June 2006 to August 2006, 20 cases of neck pain patient with hypolordotic cervical spine were divided into 2 groups. Control group(n=10) was treated only acupuncture therapy, and sample group(n=10) was treated Chuna after acupuncture therapy same as control group. Degrees of pain were measured with Visual Analogue Scale(VAS), and the change of cervical curvature was assessed Depth of cervical curve, Method of Jochumsen, and Angle of cervical curve. Results: 1. After 3th and 5th treatment, there was statistical significance between control and sample group in VAS. 2. After 5th treatment, there was not statistical significance between control and sample group in Depth of cervical curve, Method of Jochumsen, and Angle of cervical curve. Conclusions: On treating the neck pain patient with hypolordotic cervical spine, Chuna treatment is more effective than only acupuncture therapy in reducing neck pain, but Chuna treatment for short-term is not more effective than only acupuncture therapy in restoring cervical curvature.

The present study was designed to investigate the morphological developments of the stomach in the prenatal and postnatal rats. The gastric fundus of 16- to 22-day-old fetuses, neonates, 7-day-old, 14-day-old, 21-day-old, and adult rats were observed by light and scanning electron microscopy. Light microscopic studies. 1. In the 16-day-old fetuses, the walls of the gastric fundus were differentiated into epithelium, lamina propria, muscle layer, and serosa. The lamina propria was composed of mesenchymal connective tissue cells with sparse nucleus and their fibers. 2. In the 17-day-old fetuses, the muscular layer were differentiated into the circular and longitudinal muscle layers. 3. The epithelium on the fundus of stomach was stratified columnar cells at 16-, 17- and 18-day-old fetuses, but partly converted into simple columnar epithelium at 19-day-old fetuses. 4. The mucous cells were positive by PAS reaction at the 19-day-old fetuses and then these developed rapidly within 1 or 2 days before birth. 5. In the 20-day -old fetuses, the parietal cells were distinguished from other type cells and these cells were chiefly crowded in the middle parts of the gastric glands after 7-day-old. Scanning electron microscopic studies. 6. The surface of gastric mucosa was covered with forms of the various protrusions by forming villi at the last few days before birth and these protrusion forms were fused and folded each other. 7. The mucosal surface was closely packed by polygonal mucous cells. The openings of gastric glands were seen as slit-like round invagination and were more numerous and increased gradually in depth after the postnatal life. The above findings indicate that prominent changes occurred in the pattern of cellular proliferation in the stomach fundus at the end of gestation. The gastric epithelium had well-defined glands composed of parietal, chief and mucous cells just before the birth. The stomach fundus, therefore, were developed morphologically as those of normal adult at fourteen days after birth.

모바일 게임은 PC 게임, TV 게임, 손바닥 게임 이후 4번째로 독립된 산업 영역으로 중요한 플랫폼이 될 것이다. 모바일 게임은 플랫폼, 이동, 습관 등 여러 이유에서 차이점이 있다. 전 세계의 모바일 게임 플레이어의 시장자료에 의하면 모바일 게임은 2007년 7억 8000만에서 2010년에는 18억6000만까지 증가할 것으로 보인다. 또한 수입은 421억달러에서 870억달러로 증가를 지속 될 것이다. 3차원 게임은 우리의 생활에서 중대한 게임으로 즐겨왔다. 수준 높은 게임으로 사용자의 필요성을 충족해 왔고, 강력한 시각적 효과와 3차원 디자인 플레이어로 사람들에게 더 매력적으로 성장해 왔다. 강력한 시각 효과와 애니메이션 효과가 너무 지대하여 아무리 강조해도 지나치지 않다. 본 논문에서는 J2ME(자바 2 마이크로 버전) 기반의 3차원 응용 설계를 나타내었고 WTK(무선 툴킷) 시뮬레이션으로 3차원 화면에서 모바일 장치에 의한 키보드로 반응하는 3차원 물체의 자유로운 움직임을 나타내었다. Mobile games will be one of independent industries on game areas and take the fourth standing in the important platform since PC Games, TV Games, and Palm Games. There are several reasons why mobile games will differ in their platform, behaviors, and habits. According to the data of market consultation about the figure of mobile-game players throughout the world, the Mobile game will increase steadily from 780 million in 2007 to 1860 million in 2010. Also, market income will mount up from $42,100 million to $87,000 million. 3D games have been playing important roles in our lives. Satisfying users' needs in high-quality games, they have been growing and attracting more people with their powerful visual effects and the three-dimensional design player. We cannot emphasize their tremendous visual impacts and animation effects too much. This paper displays how to design 3D application based on J2ME (Java 2 Micro Edition) and shows free movement of 3D objects receiving and responding to the keyboard of mobile devices withWTK (Wireless ToolKit) simulator on the 3D screen.

본 논문에서는 가중치 이분 그래프 정합을 이용하여 데이터 최대 흐름을 나타내었다. 가중치 이분 그래프 정합은 전송 데이터 객체를 에지들로 설정하고 서버와 클라이언트에 데이터의 최대 흐름 정합을 유도 한다. 제안한 가중치 이분 그래프 정합을 이용하여 다자간 화상회의 시스템을 구현하였다. 서버에 최대한 데이터를 송신하고 클라이언트에서 최대한 수신함으로서 동영상 프레임의 끊김 현상과 병목현상이 개선되고 이미지가 깨지지 않는 우수한 성능을 나타내었다. 실험결과 기존의 흐름 제어 방법보다 약 2배의 성능을 나타내었다. This paper shows the maximum data flow utilizing the Weight Bipartite Graph Matching system. The Weight Bipartite Graph Matching system sets the data transmission as edges and guides the maximum data flow on the set server and the client. The proposed Weight Bipartite Graph Matching system implements the multi-user interface video conference system. By sending max data to the server and having the client receive the max data, the non-continuance of the motion image frame, the bottleneck phenomenon, and the broken images are prevented due to the excellent capacity. The experiment shows a two-times better excellency than that of the previous flow control.

목적: 혈청 감마-글루타밀 트랜스퍼라제(GGT)는 관상동맥 죽상경화반 내의 저밀도 지단백(LDL)의 산화과정을 촉매 하여 관상동맥 질환의 진행에 관여하며, 관상동맥 질환의 과거력이 있는 환자에서 심장사와 재경색의 독립적인 예후 예측인자로 알려져 있다. 저자는 관상동맥 질환의 과거력이 없는 급성 관상동맥 증후군 환자에서 예후 예측인자로서의 혈청 GGT의 효용성을 연구하였다. 방법: 흉통을 주소로 응급실을 방문하여 급성 심근경색으로 진단받은 환자의 혈청 GGT 값을 측정하여 응급실 방문당시 혈청 GGT 값이 정상범위(남자: 8-61 U/L; 여자: 5-31 U/L)에 있었던 192명(남/여=143/49, 평균 연령: 60.8±11.8세)의 환자를 대상으로 하여, 추적기간(16.5±10.8개월) 내 심장사건이 재발한 환자에서의 혈청 GGT 값을 심장사건이 없었던 환자의 혈청 GGT 값과 비교 하였다. 결과: 급성 심근경색 환자 192명중 추적 기간 내 17명의 환자에서 심장사와 재경색이 있었으며, 23명의 환자에서 불안정협심증이 있었다. 이 환자들의 혈청 GGT 값을 심장사건이 없었던 환자의 혈청 GGT 값과 비교하였을 때 통계적으로 유의한 차이를 보였다(29.5±10.0 U/L 대 25.0±11.2 U/L p=0.024). 그러나 다변량 분석에서 혈청 GGT에 영향을 줄 수 있는 혼란변수들과 알려진 심혈관계 질환의 위험인자로 보정하였을 경우 독립적인 예후 예측인자가 되지 못했다. 결론: 심질환의 과거력이 없는 심근경색 환자의 예후 예측인자로 심근경색의 급성기에 측정한 혈청 GGT 값은 통계적으로 유의한 차이는 있으나, 독립적인 예후 예측인자가 되지 못했다. Background: Serum gamma-glutamyl transferase activity (GGT) is able to catalyse low-density lipoprotein oxidation in coronary atherosclerotic plaques and has a role in the pathogenesis of atherosclerosis. GGT has been shown to be an independent risk factor for cardiac mortality in patients with a previous myocardial infarction. The purpose of this study is to determine the prognostic value of GGT within its normal range at an acute stage in patients with acute myocardial infarction. Methods: In a retrospective study, GGT and other cardiac risk factors were evaluated in 192 patients (M/F=143/49; mean age: 60.8±11.8 years) who were diagnosed with an acute myocardial infarction at the emergency room. We compared the serum GGT values for each patient with or without a cardiac event, including cardiac death, non-fetal myocardial infarction and unstable angina, after an acute myocardial infarction for a mean follow-up of 16.5±10.8 months. Results: During the follow-up period, 17 patients underwent cardiac death and experienced an acute myocardial infarction and 23 patients had unstable angina. Although the mean GGT values were significantly different from patients with cardiac events (29.5±10.0 U/L vs 25.0±11.2 U/L, p=0.024), serum GGT was not an independent cardiac risk factor for a cardiac event based on multivariate analysis adjusted for age, sex, alcohol and known cardiovascular risk factors. Conclusions: Serum GGT within its normal range at an acute stage in patients that experienced an acute myocardial infarction is not an independent prognostic marker. (Korean J Med 72:281-289, 2007)
