This study deals with the degree of enclosure on the Court Space in 'Suh-Won' that has warious perceptual composition elements. 1. The size of Court Space in which we can read the complexion of others and easily understand every behavior of them is similar to that of the 'Madang' in the Korean traditional houses. 2. The angles of elevation are within the range of suitable enclosure as going from the center of the court Space to 'Kang-Dang' and the space -from the center of the Court Space to 'Kang-Dang'- is restricted and surrounded. It is also within the range of the least enclosure as going from the center of the Court Space to the 'Mun-Ru'. 3. The degrees of enclosure based on the horizontal angle are within the degree we can perceive the objects of structure easily. 4. The degree of enclosure based on the ratio D/H is increased as approaching from 'Mun-Ru' to 'Kang-Dang'. The distance as approaching from 'Mun-Ru' to 'Kang-Dang' is changed from social distance to personal distance. To conclude this the Court Space in 'Suh-Won' represents the hierarchical system with variety and the degree of enclosure and the size of space are within the range of human scale.

The reconstruction of the suborbital area followed by resection of skin cancer has been used many methods including skin graft, local flaps, free flaps, and skin expansion. The radial forearm free flap has become a workhorse flap in this area because of its lack of bulk, ease of dissection, malleability, and hairlessness. When the suborbital defect especially including full-thickness defect of lower lid was reconstructed with many free flaps, the ectropion and the deformity of medial and lateral canthal area were common problems encountered as late complication due to gravitational descent. To improve the final aesthetic result in patients with suborbital defect, the radial forearm free flap was elevated as a composite radial forearm - palmaris longus free flap, in which the vascularized palmaris longus london was included and anchored to the periorbital bone with $mitek^{(R)}$ as sling, to suspend the flap against gravity and inferior descent, and thereby creating a more natural cheek contour. Two clinical cases were presented as an example of this procedure. Postoperative results emphasize the importance of suspension sling with palmaris longus tendon using $mitek^{(R)}$ in reconstruction of the suborbital defect with radial forearm free flap.

Fabrication of Micro/Nanostructures is come into the spotlight because of its potential at healthcare, electronic device and military related applications. However, existing fabrication processes contains limits in terms of rapid prototyping, due to its complicate manufacturing process, difficulties in achieving complex structure and limit of available materials. Herein, we developed novel nanoscale 3D printing system by integrating nanoparticle deposition system and focused ion beam.
혈액투석 환자의 통상 칼로리 및 단백질 섭취량이 18 개월 후의 영양상태 - 알부민 및 인체계측지표를 중심으로 - 에 미치는 영향

배 경 : 최근 단백질 섭취에 대한 DOQI 권장량에 대한 이견이 발표되고 있다. 또한 DOQI 권장량은 서구인 기준으로 체격과 식사패턴이 다른 한국인에서의 칼로리 및 단백질 권장량은 아직 명확하지 않다. 방 법 : 성균관대학교 마산삼성병원에서 혈액투석 중인 안정된 환자 50명을 대상으로 18개월간 식사량 분석과 알부민 및 인체계측 지표 등 영양상태를 연구 초와 후 사이에 비교 분석하였다. 결 과 : 두 기간에 걸쳐 칼로리 섭취는 각각 27.25±6.39, 28.99±6.38 kcal/㎏, 단백질 섭취는 각각 1.03±0.43, 1.06±0.35 g/㎏으로 모두 변화는 없었으나 권장량 이하였다. 하지만 체중은 55.22±9.48 ㎏에서 57.39±10.29 ㎏로(p=0.008), LBM(Lean Body Mass )는 42.79±7.49㎏에서 46.09±7.13 ㎏(p=0.000)으로, BMI (Body Mass Index )는 21.89±3.21 ㎏/m2에서 22.75±3.53 ㎏/㎡ (p=0.007)으로, 혈청알부민은 3.65±0.47 g/ dL에서 3.87±0.42 g/ dL(p=0.000)으로 증가하였다. Fat mass, Triceps Skin Fold thickness (TSF ), Mid- Arm Circumference (MAC), Mid- Arm Muscle Circumference (MAMC)는 변화 없이 안정되어 있었다. 결 론 : DOQI 권장량 이하의 칼로리 및 단백질 섭취에도 알부민 및 체중은 안정되었다. 칼로리 및 단백질 섭취 권장량이 한국인에서는 서구인과 차이가 있을 수 있다고 여겨진다. Background : Dialy sis patients as a group appear to have a caloric and a protein intake less than the recommended values; because their energy expenditure is not different from that of healthy adults and because amino acid loss and increased catabolism during dialysis they should be in negative caloric & nitrogen balance and lose body m ass and protein such as albumin progressively. Recently, papers dissenting about recommended protein intake in DOQI guideline were published. Because Korean people had different body size and dietary pattern from white races, recommanded protein and calorie intake may be different from that of white races. Methods : We retrospectively analyzed our data in a group of hemodialysis patients who had dietary evaluations and kinetic measurements performed two consecutive times over a period of 18 months. Results : Body weight (55.22± 9.48 ㎏ to 57.39±10.29 ㎏ , p=0.008), LBM (lean body mass, 42.79± 7.49 ㎏ to 46.09± 7.13 ㎏, p=0.000), BMI(Body Mass Index, 21.89± 3.21 ㎏/㎡ to 22.75± 3.53 ㎏/㎡, p=0.007) and serum albumin level(3.65± 0.47 g/ dL vs 3.87±0.42 g/dL, p=0.000) were increased compared to initial values . Fat mass, TSF (Triceps Skin Fold thickness), MAC(Mid-Arm Circumference), MAMC(Mid-Arm Muscle Circumference) were remained stable over this period of time. These results suggested that these patients are not in negative energy and nitrogen balance. Conclusion : Albumin and body weight remained stable over a period of 18 months in spite of 27.25±6.39 kcal/㎏ calorie intakes and 1.03± 0.43 g/㎏ protein intakes. Recommanded protein and calorie intake of Korean people may be different from that of white races.
