Ami-dong Crematorium in Busan was established as one of the public facilities in 1929(the period of Japanese Occupation). It is the originator of Busan Yeongnak-Park(永樂公園), the funeral facilities of Busan municipality. The crematorium of Busan region was accepted at an earlier stage inside Japanese Concession in accordance with the opening a port. As Ami-dong Crematorium was constructed as a public facilities, the precedent has been maintained so far, providing a background equipped with the leading public corporation facilities in Busan area. This study was based on the expansion construction document founded by National Archives in Korea. Above all things, this research revealed the establishment and change of Busan Ami-dong Crematorium as the historical point for the formation process of recent public funeral facilities.

본 연구는 1998년 9월 11일부터 11월 10일까지 경주에서 개최되는 '98 경주 세계 문화 엑스포를 중심으로 한 관광상품을 개발하기 위한 목적으로 연구를 수행하였다. 그 결과 경주지역의 기존관광코스의 경우 경주시내의 사적지 관광에만 국한하였고, 경주시에서 설정한 5개 관광권의 경우에 기존의 관광루트에 전혀 포함되지 않는 관광권(동해안권 북부문화권)이 있어 새로운 관광코스의 개발이 절실하다 하겠다. 따라서 본 연구에서는 이에 대한 해결책으로 6개 관광권을 묶어 '테마가 있는 문화 엑스포 관람'이라는 주제로 관광상품을 계획하였다. 경주시내권 서악권 불국사권을 묶어 '신라 유적 답사', 보문단지권은 '새 천년의 미소와 함께', 남산권은 '남산 불교 박물관 견학', 동해안권과 북부문화권을 끓어 '자연과 문화의 조화'라는 테마가 있는 여행을 제안한다.

It is well known that the area U of the triangle formed by three tangents to a parabola X is half of the area T of the triangle formed by joining their points of contact. In this article, we consider whether this property and similar ones characterizes parabolas. As a result, we present three conditions which are necessary and sufficient for a strictly convex curve in the plane to be an open part of a parabola.

The aims of this study are to investigate rib geometries of reinforcing bars commercially available in Korea, Japan and USA, and evaluate bond performance using beam-end test specimens. Measurement of rib geometries of the bars include nominal area, average distance of rib, height of rib and an angle of rib perpendicular to bar axis. The result of this study show that rib height of Korean reinforcement bars are much less than those of Japan and USA resulting in the lowest value of relative rib area. Average bond strength of Korean D25 deformed bars is known as 9 % less than that of bars produced in USA. Bond strength depends primarily on the relative rib area. Bond strength of the high relative rib area bars produced in USA show 18% higher than that of bars produced in Korea.

In patients with severely atrophic mandibular posterior area, implant placement is a problematic surgical procedure. Inferior alveolar nerve transpositioning technique offers better initial stability of implant and reduce the risk of permanent nerve damages. In this case report, the patient has bilateral atrophic mandibular posterior edentulous area. We placed 3 implants on each mandibular posterior area in conjunction with bilateral inferior alveolar nerve transpositioning to achieve sufficient bone height. The patient complained of paresthesia in lower lip and chin area and ptosis of lower lip after surgery. Neurosensory function was normal in 10 weeks after surgery.

Recently, strong interest in the well-being and healthy food trends lead a spreading of rice processing products such as rice noodles, rice breads, and rice cakes. However, most of rice varieties developed in Korea showed very limited processing properties in processing of noodles compare to that of wheat flour. Moreover, low competitiveness as a raw processing materials due to high price give poor evaluations for rice noodles processing. To cope those barriers, 'Saemimyeon' a Tongil type high yielding variety with a high amylose contents was developed in RDA. 'Saemimyeon' showed about 10~32 % of increase in yield as 7.08MT/ha and 26.7% of high amylose contents together with easy grinding property of 65.7% of high chalkiness ratio. The both of milled as well as brown rice of 'Saemimyeon' were well fit for processing properties in rice pasta where the contents of rice flour for rice pasta was 99% (1% of Tapioka starch was intermixed in to the rice flour). A spaghetti type for wet noodles and macaroni type for dry noodles were developed, respectively. Each of pasta were showed relatively more or less an equal quality and panel test compare to that of durum wheat pasta products. Finally, rice pasta products could suggest an alternative idea for a new rice processing items where rice noodles market was stagnant.

The officetel introduced into Korea in the mid-1980s has thus far been in the limelight as the object of investment for the substitute for small-sized housing and for lease income. But to raise the possibility of succeeding in officetel investment in the future, it has been necessary to make a systematic analysis of the changed direction of the officetel market and the profitability and stability of investment. Accordingly, this study attempted to analyze demand for officetel with a focus on the possibility of increase in the households composed of one or two members, the major consuming bracket of small-sized housing. And it attempted to analyze the possibility of investment in officetel as the investment goods for lease income due to the entry of Korea into aging society. And past analysis of investment in officetel was confined to profitability analysis, but this study sought to develop the stability indicator of the officetel for the analytical purpose. As a result, it is predicted that demand for small-sized housing will increase due to the increase in 1-to 2-person households. Accordingly, it is predicted that demand for officetel as the place of residence will come to increase. And taking into consideration the more serious degree of sustained aging in the population, older people's preference for real estate and need for lease income, it is predicted that preference for officetel as the object of investment will increase. An attempt was made to analyze the profitability and stability of investment in the metropolitan area which the officetel has principally been supplied, in order to analyze the profitability and stability of officetels. For the purpose of this study, Yeoksam-dong in Kangnam-gu, Yeoui-dong in Youngdeungpo-gu, Bongcheon-dong in Kwanak-gu were selected in Seoul as the area for analysis. Jung-dong in Wonmi-gu, Bucheon, Seohyun-dong in Bundang-gu, Seongnam, Janghang-dong in Ilsan-gu, Koyang were selected in Kyonggi province as the area for analysis. As a result, it was found that the small-sized officetel had higher profitability and stability than the large-sized officetel. It was found that the area of Kyonggi Province had the larger deviation by size. That is, it was found that the small-sized officetel in the area of Kyonggi Province was significant as the object of investment for stable lease income.

본 연구는 GIS공간분석기법과 Huff의 확률모형을 이용하여 근린생활권중심의 상권분석을 수행하였다. 연구에 사용된 기본도는 청주시 복대동을 대상으로 하여 업종, 세대수 등을 현장 조사하여 구축하였으며, 기 구축된 LMIS에 있는 연속지적도를 활용하였다. 분석에서는 커널밀도함수(Kernel Density Function)와 최근린지수(Nearest Neighbor Index)를 활용하여 근린생활권내 점포분포 중심권역을 설정하였다. 상권분석을 수행하기 위하여 설정된 중심권역에 따라 중심지(점)와 규모를 산출한 후 상권분석의 모형인 Huff 확률모형에 적용하여 중심권역별 상권을 추출하였으며, 추출된 상권을 지도로 도식하였다. 따라서 본 연구에서는 GIS 공간분석기법 중 커널밀도함수와 최근린지수를 통해 Huff 확률모형에 적용할 수 있는 방법을 제시하였다. 이러한 방법들을 이용함으로써 보다 정확하게 상권분석을 할 수 있으며, 향후 창업하고자 하는 소상공인들에 도움이 될 수 있으리라 사료된다.

Three stage(CIC-FIR-FIR) decimation filter in delta-sigma A/D converter for audio is designed. A canonical signed digit(CSD) code method is used to minimize area of multipliers. This filter is designed in 0.25um CMOS process and incorporates $1.36\;mm^2$ of active area. Measured results show that this decimation filter is suitable for digital audio A/D converters.

Purpose: The purpose of this study was to investigate the concentrations of volatile organic compounds at elementary, middle, and high schools in Ulsan and its surroundings. Methods: To assess the hazardous chemicals of the 66 classrooms in the 22 schools, the 6 volatile organic compounds such as TVOCs (Total Volatile Organic Compounds), benzene, toluene, xylene, ethyl benzene and stylene were measured and analyzed from the beginning of May to the end of December, 2009. Results: The mean concentrations of TVOCs in the elementary schools were higher than those of middle and high schools, and multi-purpose classrooms was higher than that in general ones. The benzene and toluene level in schools in Dong-Gu in the vicinity of assorted industrial complexes was higher than that of schools located in other districts around the Ulsan Metropolitan Area. Conclusion: In case of schools in Ulsan Metropolitan Area, elementary school, schools in Dong-Gu, and multipurpose classrooms over general classrooms should be given a high priority for the management of volatile organic compounds.
