The purpose of this study is to seek the basic information for the planning of modernized elementary schools in response to the 7th National Curriculum. The results of this study are as follow; 1) A multi-purpose space is put with a corridor beside classrooms as a open classroom, therefore it is increasing to demand that the multi-purpose space should be separated from the classrooms and be closed up with fixed wall, because the property of open space, the use of sound-absorbing powerless finishing materials, scarce furnitures and deficient movable partitions raise noises. In addition, it is required to aid budget for teaching tools and furniture according to supplying multi-purpose space in response to various and particular education method, and it is needed to have mind to use multi-purpose space efficiently. 2) Teachers prefer that teachers' rooms (for a grade unit) are near to classrooms and they require to secure enough space to hold a grade unit meetings. 3) To solve the problems of the method of provision with meals, it is required to research and experiment. For example, I suggest to apply the method of classroom provision to low grade students and apply the method of dining room provision to middle and high grade.

목 적 : 주상골 골절 치료에 사용하는 Herbert/Whipple 나사못의 바람직한 삽입 위치를 알아보고자 하였다. 대상 및 방법 : 4개의 사체에서 분리한 주상골을 이용하여 각 주상골마다 12개씩 주물 모형을 제작하여 대상으로 하였다. 각 모형에서 핀 삽입 안내 장치(jig, Zimmer??)를 이용하여 안내핀(guide wire)을 원위부에서 근위부를 향해 삽입하되 원위부에 A, B, C, D의 4개 근위부에 0, 5, 10의 3개의 지점을 설정하여 총 12가지 방법으로 삽입하였다. 각 모형은 주상골의 장축에 직각인 방향으로 근위부, 요부, 원위부의 세 단면을 만들고 핀 삽입의 흔적과 가장 가까운 피질골 표면과의 거리를 측정하여 이 거리가 대적으로 길 때 안전한 것으로 평가 하였다. 결 과 : 핀 삽입의 흔적과 가장 가까운 표면과의 거리가 근위부에서는 D5, 원위부에서는 C10이 유의하게 길었다. 원위 삽입 위치를 기준으로 하였을 때 근위부에서 C가 유의하게 거리가 길었고 요부, 원위부, 그리고 근위 목표 지점을 기준으로 하였을 때의 측정된 거리는 유의한 차이가 없었다. 결 론 : Herbert/Whipple 나사못의 삽입 위치는 근위부 골절에서는 D5군, 원위부 골절에서는 C5군이 가장 바람직한 위치라고 할 수 있엇고 요부 골절에서는 A0군과 D0군을 제외하면 별 다른 차이 없이 비교적 안전하다고 할 수 있다. 바람직한 위치 선정을 위해서는 근위부의 목표지점보다 원위부의 지점을 정확히 하는 것이 중요하다고 사료된다. Purpose : To evaluate optimal placement of the Herbert/Whipple screw in scaphoid fracture Materials and Methods: Forty eight model molded from four cadaver scaphoids were used for this study. Using the Herbert/Whipple jig, the guide wire was placed distal to proximal into each scaphoid with twelve method which were four entry points and three target points. Guide wire placement was then evaluated with three planes in the proximal, middle, distal planes and distance from the nearest cortex. Results : The most concentric position in the proximal plane was D5, in the middle plane C10. As distal entry point, the most concentric position in proximal plane was C. There were no statistical concentric, as middle, distal plane, and proximal entry point, Conclusion : The most ideal placement were D5 in proximal fractures of the scaphoid, C5 in distal fractures. In waist fractures of the scaphoid, there were relatively safe, except A0 and D0. The position of entry points was more important than that of target points for ideal screw placement.

Objectives : Separation and reunion is common experiences in our life but enduring unwanted early-life separation from family members may be a distressful event. This study was executed to observe emotional resolution in the subjects who eagerly desire and experience reunion with their families after long-lasting separation. Methods : Thirty subjects who have participated in the reunion program of the Korean Broadcasting System (KBS) from April 2005 to July 2005 were interviewed to assess their demographic characteristics and memories about separation. Their anxiety and depressive mood were assessed using Spielberger’s State-Trait Anxiety Inventory, Beck Depression Inventory, Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale before the family reunion. At the time of the reunion, psychological states of 14 participants who were able to meet their family members were assessed again using the same assessment tools and the follow-up assessment was performed for one possible case at 7 months after the reunion. Results : The depression and anxiety levels of most subjects were significantly decreased after the reunion. Standardized T scores of their state-anxiety were mostly in abnormal range before the reunion but most of their anxiety levels were reduced within normal range after the reunion. Duration of education was negatively correlated with trait-anxiety level and duration of separation respectively even though trait-anxiety levels were not directly correlated with duration of separation. Emotional acceptability about childhood separation tended to contribute to the increased anxiety level. Conclusion : This is the first study to assess psychological distresses of the Korean people who have suffered from long-lasting separation with their families. The results in this study suggest that the eagerly desired reunion after long-lasting separation from family may have a resolutive effect for emotional distress, further study will be needed for larger population suffering from early-life separation.

Background : Since 1997, the annual case occurrence of vivax malaria in the Republic of Korea have exceeded 1,000 cases since 1997. The military is thought to be an important source of the current outbreak. We collected various informations about malaria cases (soldiers, veterans and civilians) which occurred in 2000, and analyzed the characteristics of the current outbreak. Methods : Informations about malaria cases of soldiers, veterans and civilians, including name, age, sex, day of onset, region, etc., were collected through the National Institute of Health. Results : Out of total 4,141 cases, 1,288 (31.1%) occurred in the military, 1,273 (30.7%) occurred among the veterans, and 1,580 (38.2%) occurred among civilians. The monthly case occurrence reached its peak in early August. Areas such as Cheolwon, Yeoncheon and Paju showed the highest prevalence. Conclusion : It is considered that the current malaria outbreak has escaped from the exponential growth phase, however, more attention should be paid to prevent further spreading of malaria infection.

Aims: Abdominal ultrasonography (USG) is recommended as a surveillance test for the high-risk group of hepatocellular carcinoma (HCC). However, there is lack of information about how USG examination is actually performed in clinical practice, and how the quality control related to USG examination is managed. We investigated the incidence of HCC by a reference point of 6 months after USG was conducted. Methods: We collected data of surveillance USG from high-risk group of HCC (liver cirrhosis, or chronic hepatitis B or C over 40 years) group during 2017 in 8 tertiary hospitals. To determine the accuracy of the ultrasound examination itself, patients who had a prior history of HCC or who had CT or MRI scan within 6 months of ultrasound were excluded. If ultrasound was performed more than twice during 2017, the results of the first test were used. Results: In 2017, 45 experienced hepatologists or radiologists performed 8,512 ultrasounds. Mean age was 53.5 ± 11.0 years and, 4817 (56.6%) were males. Chronic hepatitis B was the most common indication (6319, 74.2%), and 2429 patients (28.5%) had liver cirrhosis. Doctors had 15.0 ± 8.3 years of experience, and proportion of hepatologists was higher than that of radiologists (61.4% vs. 38.6%). The time taken for the ultrasound scan was 4.1 ± 3.3 minutes excluding the preparation time. The detection rate of HCC through surveillance USG was 0.3% (29 patients). During 27 months of follow-up, a total of 60 patients (0.7%) developed new HCC. Of these, 15 patients (0.2%) were diagnosed with HCC within 6 months of the surveillance USG, and 45 patients (0.5%) were diagnosed after 6 months of the surveillance test. Conclusions: This is the first study on the current status of USG examination as a surveillance modality for HCC. It is necessary to develop quality indicator and quality assessment of USG to increase the detection rate of HCC.

Aims: It is not yet known how much relative adrenal insufficiency (RAI) affects the prognosis of patients with liver cirrhosis. We evaluated the prevalence of RAI in hospitalized patients with liver cirrhosis, and examined their association with prognosis. Methods: This study included 297 consecutive cirrhosis patients who underwent rapid ACTH stimulation test. RAI was defined by a delta cortisol lower than 9 g/dL and/or a peak cortisol lower than 18 g/dL. Results: RAI was diagnosed in 183 patients (61.6%) of the 297 patients. The group in RAI (+) had older age, a higher rate with infection, and a deteriorated liver function than the group in RAI (-). In addition, the cause of death from infection was higher in RAI (+) group than RAI (-) group (26.8% vs. 11.8%). The presence of RAI increased significantly the risk of hepatic encephalopathy, acute kidney injury and 3-month mortality. The clinical effect of RAI was further enhanced in the subgroup with relatively higher muscle mass (> ~~)and lower white blood cell count group (< 10,000 μL). Conclusions: The presence of RAI is relatively frequent in cirrhotic patients with older age, poor liver function and infection In addition, RAI significantly affects the development of complications and the prognosis of liver cirrhosis.
