This studys concerns with a critical issues of urban and rural integration for rurban development. Todays, many of urban-rural integrated cities are confronted with the negative effects of administrative boundary integration. The first problem is induced from the developmental gaps and different residential demands between the core-city and peripheral-county. The second problem is social-economic and administrative unification costs neglected. The third problem is the environmental pollutions and degradations in peripheral-county by rapid urbanization. The forth problem is the inequality of the public services and regional investments in the urban-rural Integrated cities. The fifth problem is the administrative relation and financial distribution between core-city and residual province when the urban-rural integrated core-city becomes large urban city. The results of the questionnaire analysis as follows. The first point, the preference of administrative boundary integration is different in intra-areas of urban-rural integrated county by it's location. The second point, the diversity of preference of residents depends on theirs job, age, resdential period, education and income level. So, administrative boundary integration must consider the many important factors which affect the socio-economic situations between the core-city and peripheral-county. In conclusion, residents' preference for the admistrative boundary integration depends on their situation without rational approach for macro regional development. In this contexts, comprehensive approach for the urban-rural administrative boundary integration is needed in consistent with rapid change of local government's functions.

Two cases of congenital hyperostosis at a pig farm were observed and examined pathologically in Landrace piglets. Twenty two piglets from 2 litters: 10 alive piglets in a litter and 2 stillborn and 10 alive piglets in another, were born with thickened forelimbs and some of them with thickened hindlimbs too. These piglets stowed symptoms of staggering and incoordination. Only one of these piglets could be reared normally and all the others died within 3 days of age. The thickened parts of their limbs were felt firm and not well pitted by finger pressing. An apparent ossification was identified on the central regions of the cross sections of the thickened limbs, and some pale, gray and ossiferous signs were found in the peripheral soft areas. On histopathological examination of the thickened limbs, it was found that the bone trabeculae were newly proliferated in a concentric form in central regions and in a radiated form in peripheral regions. The peripheral regions of the periosteum and perichondrium of new bone were proliferated with connective tissue and the edematous muscle bundles were atrophic and degenerative. Both the sows which produced piglets of congenital hyperostosis were mated with a different boar at next breeding and farrowed normal piglets. It was concluded that the swine congenital hyperostosis in the present cases was expressed by autosomal recessive gene of first mating boar.

Peripheral gangrene, characterized by distal ischemia of the extremities, is a rare complication in patients with falciparum malaria. Patients with this complication have generally undergone early amputation of the affected areas. In this report, we describe 3 adult Thai patients presented at the Hospital for Tropical Diseases, Bangkok, with high grade of fever ranged 6-9 days, jaundice, acute renal failure, respiratory failure, alteration of consciousness and shock. Two patients had gangrene developed at the lower extremities on day 1 of hospitalization and 1 patient had gangrene developed on day 3. Blood smears revealed hyperparasitemia with Plasmodium falciparum. These patients were diagnosed as having severe malaria with peripheral gangrene. The resolution of gangrene was successfully achieved by treatment with artesunate and conservative treatment in 2 of 3 cases.

목적: 구면 RGP 렌즈 및 비구면 RGP 렌즈를 양호하게 피팅할 때 중심부와 주변부의 플루레신 염색 면적이 난시도 및 각막형상에 따라 어떻게 달라지는 지를 비교하여 렌즈와 각막과의 정렬상태가 렌즈의 디자인에 따라 어떠한 차이가 있는지를 알아보고자 하였다. 방법: 직난시를 가진 19~30세($25.12{\pm}3.52$세)의 90안을 대상으로 구면 및 비구면 RGP 렌즈를 착용시키고 플루레신 염색 패턴을 분석하였으며, 이의 정량적인 평가를 위하여 중심부와 주변부의 면적을 계산하여 비교하였다. 결과: 양호한 피팅이 되는 렌즈의 베이스커브가 구면 RGP 렌즈와 비구면 RGP 렌즈가 동일한 경우는 72%에 달하였으나, 대칭나비형 각막과 높은 난시도를 가진 경우에는 동일한 베이스커브에서 구면 RGP 렌즈와 비구면 RGP 렌즈가 양호한 피팅이 될 가능성이 적어졌다. 양호하게 피팅된 비구면 RGP 렌즈의 주변부 플루레신 염색 면적은 구면 RGP 렌즈보다 더 작았으며, 두 디자인의 렌즈 모두 난시가 심해질수록 주변부 면적은 감소하였고 원형 각막보다도 대칭 나비형 각막에서의 주변부 면적이 더 작았다. 동일한 난시도의 각막에서는 두 각막 형상 모두에서 양호하게 피팅된 비구면 RGP 렌즈의 주변부 플루레신 염색 면적이 더 작았다. 결론: 본 연구를 통하여 RGP 렌즈의 각막과의 정렬상태의 달라지는 정도가 렌즈 디자인, 각막의 난시도, 각막 형상에 의해 차이가 있음을 알 수 있었다. 따라서 렌즈 디자인과 각막의 정렬상태의 정량적인 고찰을 통한 본 연구결과는 RGP 렌즈의 피팅 가이드라인 설정, 적합한 디자인 개발, 부분별 누액양에 대한 기초자료로 사용될 수 있을 것이다.

The Chinese began migrating to Vietnam very early (in the third century BC) and continuously underwent either mass or small migration afterwards. Their long processes of living and having contact with different ethnic communities in Vietnam made the Chinese worship of Goddess Tianhou change radically. By examining these practices of worship in two areas where the Chinese settled the most, Thừa Thiên Huế province (central Vietnam) and Hồ Chí Minh City (southern Vietnam), this paper aims to understand the patterns of acculturation of the Chinese community in its new land. An analysis of information from both field research and archival sources will show how the Chinese have changed the worship of the Tianhou goddess during their co-existence with ethnic communities in Vietnam. It argues that there is no "peripheral fossilization" of the Chinese culture in Vietnam.

Purpose: The study was done to explore variations in physiologic parameters of the stratum corneum (SC) of the dorsal hand and cord area during early days of life in high-risk newborns. Methods: In this longitudinal study, a total of 77 high-risk newborns were assessed for pH, temperature and hydration of the SC of the dorsal hand and the cord area on the $1^{st}$, $2^{nd}$, $3^{rd}$, $5^{th}$ and $7^{th}$ days of life. Results: Results showed that an acid mantle (AM) was formed in 57.1% for dorsal hand and 35.1% for cord area, implying significant delay regardless of decrease in pH (F=103.60, p<.001), and hydration (F=4.00, p=.003) across days in both areas. Peripheral hypothermia with low hydration level was also observed in both areas. There was a positive relation between hydration and temperature (.14

Primary non-Hodgkin's lymphoma of the lung is rare among extranodal lymphomas. The most common form is low grade B-cell type originated from the mucosa-associated lymphoid tissue (MALT) of the lung and primary peripheral T cell lymphoma of the lung is extremely rare. We recently experienced a case of fine needle aspiration cytology of primary peripheral T cell lymphoma of the lung in a 39-year-old male patient. The cytologic smears revealed some sheets of reactive epithelial cells, epithelioid histiocytes, and numerous polymorphous population of lymphoid cells composed of small and intermediate sized lymphoid cells and mature lymphocytes. Lymphoid cells were slightly larger than normal mature lymphocytes and showed significant irregularity of nuclear membrane. The internal nuclear structure was marked by chromatin clumping, clear parachromatin areas, and inconspicuous nucleoli. Histopathologically, atypical small lymphocytes infiltrated in the interstitium and alveolar sac. By the immunohistochemical study and molecular biologic study of gene rearrangement, the T cell clonality of atypical lymphoid cells was confirmed.

Objective: To assess the regional ventilation in patients with asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) using xenon-ventilation dual-energy CT (DECT), and to compare it to that in patients with COPD. Materials and Methods: Twenty-one patients with ACOS and 46 patients with COPD underwent xenon-ventilation DECT. The ventilation abnormalities were visually determined to be 1) peripheral wedge/diffuse defect, 2) diffuse heterogeneous defect, 3) lobar/segmental/subsegmental defect, and 4) no defect on xenon-ventilation maps. Emphysema index (EI), airway wall thickness (Pi10), and mean ventilation values in the whole lung, peripheral lung, and central lung areas were quantified and compared between the two groups using the Student's t test. Results: Most patients with ACOS showed the peripheral wedge/diffuse defect (n = 14, 66.7%), whereas patients with COPD commonly showed the diffuse heterogeneous defect and lobar/segmental/subsegmental defect (n = 21, 45.7% and n = 20, 43.5%, respectively). The prevalence of ventilation defect patterns showed significant intergroup differences (p < 0.001). The quantified ventilation values in the peripheral lung areas were significantly lower in patients with ACOS than in patients with COPD (p = 0.045). The quantified Pi10 was significantly higher in patients with ACOS than in patients with COPD (p = 0.041); however, EI was not significantly different between the two groups. Conclusion: The ventilation abnormalities on the visual and quantitative assessments of xenon-ventilation DECT differed between patients with ACOS and patients with COPD. Xenon-ventilation DECT may demonstrate the different physiologic changes of pulmonary ventilation in patients with ACOS and COPD.
