For medical students and doctors, knowledge of the 3-dimensional (3D) structure of the heart is very important in diagnosis and treatment of the heart diseases. 2-dimensional (2D) tools (e.g. anatomy book) or classical 3D tools (e.g. plastic model) are not sufficient or understanding the complex structures of the heart. Moreover, it is not always guaranteed to dissect the heart of cadaver when it is necessary. To overcome this problem, virtual dissection systems of the heart have been developed. But these systems are not satisfactory since they are made of radiographs; they are not true 3D images; they can not be used to dissect freely; or they can only be operated on the workstation. It is also necessary to make the dissection systems incorporating the various races and tribes because of the organ's difference according to race and tribe. This study was intended to make the 3D image of the heart from a Korean cadaver, and to establish a virtual dissection system of the heart with a personal computer. The procedures or manufacturing this system were as follows. 1. The heart from a Korean adult cadaver was embedded with gelatin solution, and serially cross-sectioned at 1mm-thickness on a meat slicer. Pictures or 153 cross-sectioned specimens were inputted into the computer using a digital camera ($756{\times}504$ resolution, true color). 2. The alignment system was established by means of the language of IDL, and applied to align 2D images of the heart. In each of 2D images, closed curves lining clean and dirty blood pathways were drawn manually on the CorelDRAW program. 3. Using the language of IDL, the 3D image and the virtual dissection system of the heart were constructed. The virtual dissection system of the heart allowed or ree rotation, any-directional sectioning, and selected visualization of the heart's structure. This system is expected to become more advanced, and to be used widely through Internet or CD-title as an educational tool for medical students and doctors.

Objectives : For investigating relationship between oral condition and body mass of adolescent period and helping to make basic data which make oral care systematically while performing health care for adolescent. Methods : This research was carried out by performing oral and physical test of 273 high school students in some reasons from July 2nd to 16th in 2012. Results : There were significant differences, since the more subjects had irregular occlusion, the more they had loosing tooth(p<0.05). There was a significant difference, since when subjects had more numbers of regular occlusion, they had higher BMI and heavier weight.(p<0.001). There are significant different, since when the subjects had worse peridontal condition, they had more numbers of DT(p<0.001). There was a significant difference in occlusion and body mass group, since when subjects had regular occlusion, 46.4% of subjects were standard body weight, 41.0% of subjects were overweight and when subjects needed orthodontics, 52.7% of subjects were standard body weight, 33.8% of subjects were low-weight, and 13.5% of subjects were overweight(p<0.001). In the correlation between oral condition and BMI, DT index showed negative interrelation with FT index(r=-0.179) and positive interrelation with periodontal condition(r=0.221), MT index showed positive interrelation with occlusion(r=0.137) and FT index showed positive interrelation with height(r=0.136). BMI showed highly positive interrelation with weight(r=0.940), and when occlusion was worse, it shows negative interrelation with BMI(r=-0.293). Height showed highly positive interrelation with weight(r=0.447), and when the more subjects had malocclusion, it showed low negative interrelation with weight (r=-0.257). Conclusions : It was considered that an adolescent period forms health habits, so it was important to increase health action through education for growing healthy adult and not only guiding improvement of dietary life for keeping normal weight, but also conducting oral health education for treating regular occlusion of oral condition and prosthetic procedures for loosing tooth right time.

Purpose : This study investigated the effects of concentric and eccentric contractions on muscle strength using an isokinetic dynamometer (ID) in college students in their 20s. It aimed to understand the impact of differences between the dominant and non-dominant sides on strength asymmetry and to elucidate the clinical implications of these differences to establish an appropriate posture and environment for patients. Methods : The experiment was conducted with 30 healthy adult participants. Prior to the experiment, participants underwent a warm-up targeting the shoulders, and efforts were made to eliminate factors that could potentially influence the measurement results. Subsequently, the maximum safe range of motion of shoulder joint abduction, extension, and flexion was measured using an isokinetic muscle function testing device. Muscle strength was assessed using concentric and eccentric contractions alternating between the dominant and non-dominant sides, and paired sample t-tests were used for the analysis. Results : There was no significant difference between bilateral peak torques for eccentric contraction in shoulder joint abduction, extension, and flexion (p>0.05). There was also no significant difference between bilateral peak torques for concentric contraction in shoulder joint abduction, extension and flexion (p>0.05). Conclusion : This study found no statistically significant difference in muscle strength between the dominant and non-dominant sides during concentric and eccentric contractions. However, previous studies have shown significant differences between the dominant and non-dominant sides during eccentric and concentric contractions during internal shoulder rotation in the general population, as well as significant differences in the upper trapezius muscle. Therefore, further research is needed to support the application of different intensities for bilateral muscle strengthening exercises in clinical practice.

연구배경 : 수면다원기록에 따르는 첫날밤 효과가 수면연구자들 사이에서 널리 알려진 개념임에도 불구하고 이에 대한 국내 연구가 전무한 형편이고 한편으로는 이제까지의 연구결과들의 일관성이 없어 우선 건강한 젊은 성인을 대상으로 첫날밤 효과에 관해 연구 하고자 하였다. 방법 : 남자 의과대학생 8 명을 대상으로 2 일간의 야간수면 다원기록을 실시하여 산출된 수면 변인들에 대 하여 첫째 날과 둘째 날의 결과를 비교 분석하였다. 결과 : 양 일간의 유의한 차이는 첫날밤에 수면기간 시간과 취침시간을 3 등분한 후반 1/3의 총수면 시간이 증가한 소견이었다. 그 외 제반 변인에서는 유의한 차이를 발견할 수 없었다. 결론 : 본 연구에서 첫날밤 효과를 확인할 수 없었던 것은 1) 피험자들의 나이가 젊어 적응력이 뛰어났고, 2) 검사실 환경이 비교적 쾌적하여 집의 침실과 같은 안락한 환경을 제공하였기 때문으로 생각된다. 피험자의 연령과 수면 검사환경을 고려하지 않고 첫날밤 효과를 배제하기 위해서 무조건적으로 첫날밤의 수면다원기록 자료를 경시 또는 제외할 필요는 없다고 판단된다.

이 연구는 남한에서 탈북민으로 살아가는 대학생과 성인여성들에 대한 면담을 통하여 실질적인 사회 생활에서의 적응과정을 알아보고, 우리 모두의 삶이 행복하기 위해서는 교육측면에서 어떻게 나아가는 것이 바람직한 것인가를 알아보고자 하였다. 연구방법은 반구조화된 면담으로 이루어졌다. 면담기간은 4개월이었다. 면담 결과를 토대로 다음과 같은 결론을 제시하고자 한다. 첫째, 교육에서 갈등보다는 협력강화, 같은 민족이라는 동질성 회복을 위한 방향설정을 확고히 할 필요가 있다. 6.25동란과 같은 동족상잔의 전쟁으로 인해 갈등의 골이 깊어진 상황에서 쉽지 않은 현실적 어려움이 존재하는 것도 사실이다. 그러나 65년이 지난 현시점에서 국가가 과거에만 머물 수는 없다. 둘째, 탈북민에 대한 경제적 지원을 못마땅하게 생각하는 인식도 성인들에게서 일부 존재한다는 점이다. 셋째, 남한 사람들의 통일에 대한 부정적인 생각도 상대적으로 높게 나타난다. 이는 통일비용에 대한 증가로 인해 사회복지와 경제성장의 기반이 약회된다는 주장에 기인하고 있는 것으로 사료된다. 넷째, 학교교육에서 지식중심의 교육과 함께 문화예술과 같은 실생활에서 살아가는 내용도 동일 비중으로 다루어야 한다. 이를 통해 탈북자들도 남한 국민들과 동일한 행복을 누릴 수 있는 환경이 이루어져야 한다.
