목적: 위식도접합부선암의 임상병리학적 특성은 서구와 아시아 간의 많은 차이를 보인다고 알려져 있다. 그러나, 한국의 경우 위식도접합부선암의 유병율이 매우 낮고 이에 대한 연구 또한 부족하다. 따라서 저자들은 우식도접합부선암의 Siewert 분류에 따른 임상병리학적 특성을 조사하여 서구와 다른 국내 위식도접합부선암의 특성을 연구하고자 하였다. 대상 및 방법: 2004년 5월부터 2008년 2월까지 본원에서 위암으로 수술을 시행 받은 환자들을 대상으로 수술소견 및 병리 사진을 토대로 Siewert 분류법에 따라 위식도접합부선암을 분류하고, 의무기록을 바탕으로 환자들의 임상병리학적 특성들을 조사하였다. 결과: 위식도접합부선암은 전체 1,778예 중 70예(3.9%)였다. Siewert 1형은 3예(4.3%)로 매우 드물었으며, 2형과 3형이 각각 30예(42.8%) 37예(52.8%)였다. 2형이 3형에 비하여 평균연령이 높았으나(64세 vs 59세, P=0.049), 남녀비에는 차이가 없었다. 2형과 3형간에 Barrett 식도의 발현 정도나 Lauren 분류의 차이는 없었으나, 저분화암의 빈도는 3형에서 유의하게 높았다(P=0.045). 68예(97.1%)에서 근치적 절제가 시행되었으며, 각 아형간에 TNM 병기의 차이는 없었다. 결론: 국내의 위식도접합부선암은 매우 드물며 특히 1형의 유병율이 매우 낮다. 본 연구에서 서구의 보고와 부분적으로 일치하지 않는 병리학적 특성을 보였다. 향후 보다 많은 환자들을 대상으로 한국인의 위식도접합부선암의 특성을 연구할 필요가 있다. Purpose: Siewert's classification of adenocarcinoma of the esophagogastric junction (AEG) has been widely adopted, but there is a wide discrepancy of the clinicopathological features of AEG of the Asian patients as compared to that of the Western patients. The aim of this study was to investigate the clinicopathological characteristics of AEG according to the Siewert classification. Materials and Methods: Among the patients who underwent surgery for gastric carcinoma in our institution between May 2004 and February 2008, the AEG patients were selected based on their operation records and the photographs according to Siewert's classification. Results: There were 70 AEG patients (3.9%) among the total of 1,778 patients. There were 3 patients (4.3%) with type I, 30 patients (42.8%) with type II and 37 patients (52.8%) with type III. Curative resection (R0) was achieved in 68 cases (97.1%). No significant differences in gender, stage, Barrett's esophagus and the proximal margin were found between the patients with type II and type III AEG. The patients with type III were younger than the patients with type II (59 vs 64 years, respectively, P=0.049). Well differentiated histology (P=0.045) and the intestinal type (P=0.055) were significantly more frequent in the patients with type II as compared with that in the patients with type III. Conclusion: There was a striking difference of the Asian patients from the Western patients for the incidence of AEG (and especially type I). Some of the differences between type II and type III patients were similar to those of the previous Western studies. A large study is needed to investigate whether these features are typical in the Korean population.

Background and Objectives : The most important two factors of the voice production are the respiratory function which is the power source of voice and the glottic closure that transform the air flow into sound signals. The purpose of this study was to investigate the differences between trained singers and untrained controls under varying intensity at a constant vocal pitch by simulataneous using the airway interruption method and electroglottography(EGG). Materials and Methods : Under two different intensity condition at a constant vocal pitch(/G/), 20(Male 10, Female 10) trained singers were studied. Mean flow rate(MFR), subglottic pressure(Psub) and intensity were measured with aerodynamic test using the Phonatory function analyzer. Closed quotients(CQ), jitter and shimmer were also investigated by electroglottography using Lx speech studio. These data were compared with that of normal controls. Results : MFR and Psub were increased on high intensity condition in all subject groups but there was no statistically significance. Statistically significant increasing of CQ. were observed in male trained singers on high intensity condition (untrained male : 51.31${\pm}$3.70%, trained male :55.52${\pm}$6.07%, p=.039). Shimmer percent, one of the phonatory stability parameters, was also decreased statistically in all subject groups(p<.001). Conclusion : The trained singers' phonation was more efficient than untrained singers. The result means that the trained singers can increase the loudness with little changing of mean flow rate, subglottic pressure but more increasing of glottic closed quotients.

Based upon the research and analysis on the downtown residents' satisfaction with their current housing areas and preference for future housing areas, this study clarifies the following. First, the breakdown on various factors influencing the housing environment indicates that downtown residents are the most satisfied with the easy access to the public transportation, and cultural and commercial facilities. Second, they are not content with the amenity aspects such as the air, noise, and the surrounding views, and the economic aspects such as the prices of the houses and the prospects for future investment. The low satisfaction suggests that the amenity aspects and economic aspects should be considered for future downtown housing development. Third, more than half of the residents in downtown areas still prefer to dwell in downtown areas. In the future downtown development, the close analysis on the characteristics of downtown dwelling, and the researches on the right direction of downtown housing development for the whole citizens of Daegu should be done in advance. Last, the majority of people wishing to reside in downtown want medium- or large-scale apartment complexes. In the future downtown housing development, it should be focused on the downtown residence with complex functions rather than on the small-scale maintenance projects.

Vocal fold injections are usually performed with a patient wake in an office under local anesthesia. For comfortable and safe office-based procedures, thorough anesthesia and premedication should be provided to the following three regions; nasal cavity, oropharynx, and larynx. Topical lidocaine is most widely used anesthetics on office based procedure. Lidocaine has a low to intermediate potency, 45 minutes to 60 minutes' duration of action, and onset of sufficient anesthesia within 90 seconds of topical administration. Tetracaine, prilocaine, ropivacaine, and bupivacaine also have been used in the office-based procedures. Nasal decongestant, oxymetazoline, is also used for widening nasal cavity by constriction of nasal mucosa. The amount of topical and local anesthetics used in vocal fold injection rarely exceeds toxic doses. The physician should know proper anesthesia techniques and must be familiar with the safe dose and complication of all anesthetics used.

This study aims to analyze the on-site improvement area of residential environment improvement project based on research results derived from the on-site and questionnaire survey in case of Daegu. The main findings are as follows. First, residents complain about delay of project completion because a long time has been passed after on-site improvement area was designated. Experts and government officials agree that a new method of development is required. Second, future development should discriminate on-site improvement area according to its level of project completion. The area should be classified into project completion areas and on-going area, and new methods, such as redevelopment, apartment-housing construction method, should be allowed. Third, for better management of on-site improvement area, laws and regulations must be ready and government's will for improvement is crucial.

The primary purpose of this study is to suggest policy directions for redevelopment project based on analysis of residents' perception on needs and reasons of redevelopment, and development type in old settlements in Daegu Metropolitan City. The main findings are follows. First, the study area is short of public space such as road and parks, occupied by old single detached houses with small parcel. The living environment of the area consist with many 20 years or older two story houses is very poor. Second, most of residents (58.5%) consider economic factors or cheaper rent more serious than other factors such as convenience, amenity, and education facilities. Third, residents want new housing construction even though explanatory power of trash collection, bad smells, privacy is very high in residents' satisfaction. Fourth, most of residents (88.8%) agree redevelopment and show strong preference to high-density apartment construction through demolish-and-development type of redevelopment approach. They are willing to agree the parcellevel redevelopment if governments provides economic supports and temporary settlements. This finding suggests very important policy implications for current government efforts to improve living environment.
