Many Korean university campuses are located on hilly terrain where the hierarchy of the path system is unclear. Therefore, it is difficult to analyze the pedestrian network through space syntax, in which only horizontal direction changes are considered as depths of space. The purpose of this study is to compare pedestrian movement patterns and space syntax analysis in order to find their relevance to each other and the relationship between them. We conducted a survey regarding the most-visited buildings and pathways at S-University, which is located on a hilly area in Seoul. The survey results were compared with the Space Syntax integration map by regression analysis. For the segments where the relationship between pedestrian volume and integration was weak, field observations were conducted. As a result, topographical aspects, functional aspects, and location aspects were observed as the main influential factors. In addition, the research proposes that adding an extra axial line per vertical directional change can potentially compensate for the low relevance of stairs. This study suggests the possibility and the necessity of three-dimensional space syntax programs and emphasizes the importance of campus planning for the pedestrian environment.

YAG:Ce yellow phosphor particles were synthesized by spray pyrolysis with changing the solution properties and their luminous properties, crystal structure, and morphological changes were studied by using PL measurement, XRD, and SEM analysis. It was clear that the solution properties significantly affected the crystal phase, crystallite size, the PL intensity, and the morphology of YAG:Ce particles. At low calcination temperature, the addition of urea only to the spray solution was helpful to form a pure YAG phase without any impurity phases, as the result, the highest luminescence intensity was achieved at the calcination temperature of $900^{\circ}C$. When the calcination temperatures were larger than $1300^{\circ}C$, however, the YAG particles prepared without any additive showed the highest luminescent intensity. Regardless of the solution conditions, the emission intensity of YAG:Ce particles prepared by spray pyrolysis showed a linear relation with the crystallite size. In terms of the morphology of YAG:Ce particles, the addition of both DCCA and $NH_4OH$ to the spray solution was effective to prepare a spherical and dense structured YAG particles.

The epidemiological researches on the inpatients hospitalized at the oral medicine ward have been continuously carried out since 1970, and most researches have been performed by centering around the oral medicine wards of college hospitals. Numerous specialists have been produced after the establishment of oral medicine, and they have been active in various fields. As dental clinics have gotten bigger, the function of oral medicine in the secondary clinics is being brought out. As admissive channel, case features, case composition and otherwise have not been researched for a long time, the related researches should be carried out from now on. Hereupon, this study was carried out by targeting the 100 inpatients hospitalized at the oral medicine ward of Sun Hospital located in Daejeon Korea, through questionnaire. As the result, the following results were derived. 1. The ages of the inpatients in Sun Hospital were $29.21{\pm}11.31$ on the average; 71 females' mean average was $29.63{\pm}11.29$ and 29 males' mean average was $28.17{\pm}11.48$. In regard of school career, the patients who finished high-school course or higher accounted for 78%; the patients' school career seemed to be relatively high. The patients who complained of temporomandibular pain accounted for the highest proportion with 65%. In motivation to visit this hospital, internet surfing was 11%, mass media was 10%, acquaintance's introduction was 38%. The patients, who were hospitalized at another hospital due to the same symptom, accounted for 56%. The dental clinics, which made the patients visit this hospital, accounted for 20%. The patients, who were previously aware that the present symptom should be treated by oral medicine, accounted for 38%. The patients, who were not aware of the fact in advance, were 62%. The respondents of 51% answered that they were aware of the fact one month or below before hospitalization. 2. The patients, who complained of craniocervical ache, accounted for 58%; the patients, whose ache aches affect dailylife, were 22%. Continuous ache was 14% and intermittent ache was 68%, and dull pain was 23%. 3. Life variations were compared with each other by using SRRS (Social Readjustment Rating Scale). In consequence, the variation within 3 years indicated a significant difference in the both groups but the variation within 6 months did not indicate any differences. 4. In regard of the questionnaire on the incidents happened for a week, the ache-group was compared with the group free from the ache. As the result, the number of strain arisen for a week, the decrease of favorite works and sudden fear indicated a significant difference. Pleasant feeling and the decrease of interests in looks did not indicate a significant difference, but came close to the significance. 5. In the questionnaire on impatience, the ache-group indicated higher value but there was not a significant difference. 6. In the questionnaire on the symptoms caused by stress, the two groups indicated significant differences in the item of 'the teethridge itches and feels a tooth rising' and 'the occiput or the nape is stiff.' In the item 'the inside of the cheek or the teethridge are widely peeled off, accompanied with ache and hemorrhage', 'the face has acne or pimple' and 'headache frequently attacks', a significant difference was not observed but the two groups came close to the significance.

말기 신부전증에 의한 이차성 부갑상선 기능항진증 환자에서 부갑상선 조직의 세포자가사멸 연구

이유미,이재복<SUP>1<,SUP>,Yu Mi Lee,Ph,D and Jae Bok Lee,Ph,D,<SUP>1<,SUP> 대한갑상선-내분비외과학회 2008 The Koreran journal of Endocrine Surgery Vol.8 No.4

Purpose: The cause of renal hyperparathyroidism is unclear and the role of hyperphosphatamia is the only well established cause of renal osteodystrophy. The long life span of the parathyroid cells and the absence of a definite tissue marker for nodular parathyroid gland prohibit the timing of surgical intervention. The discrepancy between proliferation and apoptosis has been proposed as one possible cause of nodular development of the parathyroid gland in patients suffering with renal osteodystrophy. In the present study, we investigated the apoptotic labeling index of the parathyroid tissue in patients with renal hyperparathyroidism. Methods: The parathyroid tissues of 76 patients with renal hyperparathyroidism and those of 33 normal glands were used for determining the level of apoptosis by performing a Tdt-mediated dUTP nick end labeling (TUNEL) assay. The patients' information was collected by a review of the clinical charts. Statistical comparison was done via two tailed t-tests. Results: The averages of the TUNEL indices were 0.19 in the normal parathyroid glands and 1.84 in the hyperplastic parathyroid glands (P=0.00). The TUNEL index was higher in the oxyphil type of cells than in the chief cells and the water clear cell types (P=0.01). There was statistically significant correlation of the TUNEL index with the duration of the dialysis and less than 10 years dialysis showed a 2.23 index, which was higher than that of the longer term dialysis patients (P=0.00). The preoperative PTH level, recurrence, the Ki-67 labeling index and the pathologic type didn't show any statistical correlation with the TUNEL index (P>0.05). Conclusion: Our findings showed that the TUNEL index is useful for separating the cases of advanced renal hyperparathyroidism from the early ones and the TUNEL index is well correlated with hyperplastic types of cells. A decrease of apoptosis could be a probable cause of the progression of parathyroid hyperplasia in renal patients who are on dialysis support. (Korean J Endocrine Surg 2008; 8:250-255)

인산염의 첨가와 침지가 저지방 소시지의 냉장저장 중 품질과 저장성에 미치는 영향

이유미,진구복,Lee, Yu-Mee,Chin, Koo-Bok 한국축산식품학회 2012 한국축산식품학회지 Vol.32 No.1

This study was performed to determine the quality characteristics and shelf-life of low-fat sausages (LFS) with 0.4% sodium tripolyphosphate (STPP) alone or in combination with a 10% trisodium phosphate (TSP) solution during refrigerated storage. When 0.4% STPP was added, no differences in pH values were observed. However, pH values increased with the addition of the TSP solution when 0.4% STPP was incorporated. The addition of STPP into LFS decreased redness and the dipping in the TSP solution increased yellowness (p<0.05). Total bacteria and Listeria monocytogenes, which inoculated Log $10^{3-4}$ colony forming units (CFU/g) were increased with increased storage time. At 4 wk of storage, total bacteria and Listeria monocytogenes reached levels of 8.03-8.22 Log CFU/g, however they decreased to 7.89 Log CFU/g at 8 wk of storage time. Due to the pH increases, Listeria monocytogenes significantly increased in LFS dipping with 10% TSP. Based on these results, LFS dipping with 10% TSP solution promoted the growth of Listeria monocytogenes, regardless of STPP addition. These results indicated that 0.4% STPP addition and dipping with TSP affected the pH and color, however, it didn't extend the shelf-life of LFSs during refrigerated storage. 본 연구는 인산염의 첨가와 침지가 저지방 소시지의 저장기간에 따른 품질 및 저장성을 평가하기 위해 실시하였다. 저지방 소시지에 0.4% STPP를 첨가하고, 10% TSP 용액에 침지함에 따라 pH값이 증가하였다. STPP의 첨가에 따라 적색도가 감소하는 반면, 10% TSP 침지구의 황색도는 증가하였다(p<0.05). 저장기간이 경과함에 따라 명도는 유의적으로 감소한 반면 적색도는 유의적으로 증가하였다(p<0.05). 약 5 Log CFU/g로 접종된 Listeria monocytogenes(LM) 균수는 저장기간이 경과함에 따라 4주에 8.03-8.22 Log CFU/g로 나타났고 8주에는 7.89 Log CFU/g로 약간 감소했다. 접종된 저지방 소시지의 저장 중 총균과 LM균의 성장은 10%의 TSP 침지에 의해 pH의 증가로 유의적으로 더 촉진된 것으로 판단된다. 이와 같은 결과를 종합하면 인산염 첨가 및 침지는 pH와 색도(명도와 황색도)에 영향을 주었으며 저장기간 중 뚜렷한 항균 및 항산화 효과는 없었다.
