Korea's pet-related society has been fast growing without the base and preparations of socio-cultural animal welfare. For the most part, Korea's current public parks, in particular, have a space structure in which a lot of friction between the general public who are not fond of dogs and dog owners in public places has been happening unavoidably. A lot of countries that are taking a lead role in animal welfare have built dog parte that the general public and dogs can enjoy together. This research starts with the realization that the concept of 'dog park' needs to be introduced in Korea as more and more Koreans own dogs and other pets. This research aims to provide guidance for dog park planning by drawing a dog park planning model and to promote basics for co-existence of dogs and people in a park and set in place animal welfare early and raise the level of awareness. Total 7 types of dog put 56 planning items including dog zone, dog playground, and agility, and a selective matrix by which it is possible to select essential recommendatory optional items by each type of dog park were drawn in this research. Overall there were the highest needs in separated area for dogs in park. A dog park planning model is designed as follows. 1) To select a dog park type that was introduced. 2) To set up facilities applicable in common and planning items desired in advance by each type. 3) To zone dog park areas by the priority order of planning items that were introduced and to position necessary facilities. 4) To plan program that should be were introduced. A dog park was expected to take some positive roles such as providing opportunities to socialize dogs, activating social communities, more effective park management by participating local community members and so on.

We estimated the potential area roof greening in Gyeonggi-do that will mitigate the heat island effect. The estimation was based on building age, roof shape, and building use which were recorded in the building register from "Sewoomteo, the Building Administration System in the Ministry of Land, Transport and Maritime Affairs. The estimated potential roof greening area in Gyeonggi-do was approximately 102.5㎢ assuming that the buildings for residence, public, education(school), office, shopping mall are appropriate for roof greening. The area occupied by apartment buildings over six-story was 76.3% of the potential roof greening area 10.2% for individual houses, 5.9% for under five-story apartment buildings, and 3.7% for school buildings. The result indicated that it is residential buildings that we need to pay attention for roof greening, especially high-rise buildings over six-story. Greening of the whole estimated area, 102.5㎢, in Gyeonggi-do will result in the increase of green space per capita by 8.74㎡. This is 1.65 times greater than the area of current urban parks, and 1.97 times greater than the total area of neighborhood parks, children`s parks, and pocket parks. Greening of the estimated roof area will increase green coverage of urban area by twice, adding to current green coverage of the urban areas, 11.3%, in 10 major cities. In particular, the effect of roof greening would be remarkable in inceasing the green space of Anyang City, Gwangmyeong City, and Guri City where neighborhood park area falls short.

Body condition score (BCS) is a useful management tool for distinguishing differences in nutritional needs of cows in the herd. Although it is not always possible to quantify the nutrient content of the feed supplied to the donor cow, the nutritional status can be determined by the BCS. The objective of this study was to evaluate in vivo embryo production, return to estrous of donor and pregnancy rate of recipients following BCS in Hanwoo superovulation. Sixty nine Hanwoo donor cows were flushed on day 7 of estrus cycle with same FSH and artificial insemination by the same technicians. Embryos were recovered on 7 days after the third insemination by flushing the uterus with Embryo Collection Medium. The results obtained were as follows: No differences were observed in the efficiency of superovulation rates regardless of BCS (≤2.0, 2.5 to 3.0, and ≥3.5). The mean number of total embryos was each 5.20±0.86, 11.56±1.04, and 6.23±1.07. The mean number of transferable embryo from ≤2.0, 2.5 to 3.0, and ≥3.5 of BCS was 2.60±0.87, 7.94±0.89, and 4.75±1.32, respectively (p<0.05). Return to estrous regardless of donor BCS was no difference. The pregnancy rates of recipient were BCS ≤2.0 11.76%, 2.5 to 3.0 40.79%, and ≥3.5 11.11%, following transfer of fresh embryos produced in vivo, respectively. These results indicate that if the Hanwoo with BCS 2.5 to 3.3 are used for donor and recipient, the embryo production and the conception rate will be greater.

박양수,김현규,문남두,이명준 울산대학교 1999 공학연구논문집 Vol.30 No.2

분산응용시스템은 서비스의 효율향상을 위해 일반적으로 병행성을 지원하는 것이 바람직하다. 그러나 병행성을 지원하기 위한 프로그래밍 기법은 난이도가 높은 구현 기법이며, 대부분의 프로그래밍 언어에서 이를 직접적으로 지원하지 않으므로, 분산응용시스템을 위한 개발자의 부담을 가중시키고 있다. 본 논문에서는 현재 분산응용시스템의 작성에 널리 쓰이고 있는 Java에서 병행성을 체계적으로 지원하기 위한 기반으로서, 세미포어나 조건변수와 같은 고수준 동기화 도구의 개발에 대해 소개하였다. 이러한 Java고수준 동기화 도구는 순수한 Java로 개발되어 이식성을 지니고 있으며, 개발자가 쉽게 기술할 수 있는 인터페이스를 제공하고 있다. 또한 Java가 지닌 대중성으로 인해 대부분의 분산응용시스템의 구축에 널리 사용될 수 있을 것으로 기대된다. In a development of distributed applications, it is desirable for a server to support concurrency in order to provide effective services. However, the programming mechanism for concurrency is difficult to implement correctly, so most programming languages do not support this facility directly. Therefore, the fact imposes extra burdens to the developers for distributed applications. The high-level synchronization tools such as Semaphores and Condition Variables in Java are suggested as a basis for systematically supporting concurrency control. The suggested high-level synchronization tools also have a good portability since it has developed in pure Java. In addition, due to the popularity of Java, these tools will ho a long way with developers in building distributed systems.

박남규 한국공업화학회 2004 공업화학 Vol.15 No.3

빛에너지를 전기에너지로 직접 변환 시키는 태양전지는 구성하는 물질에 따라 무기물 태양전지와 유기물 태양전지로 나눌 수 있다. 무기물 태양전지는 실리콘, 화합반도체 등의 소재가 pn 접합으로 구성되어 있으며, 유기물 태양전지는 염료분자가 나노결정 입자 표면에 흡착되어 있는 것을 특징으로 하는 염료감응형과 donor-acceptor 특성의 유기(고)분자형으로 나눌 수 있다. 특히 염료감응형 유기태양전지는 높은 에너지변환 효율(약 11%)과 매우 낮은 제조가격 때문에 차세대 태양전지로 각광받고 있다. 본 총설에서는 염료감응 태양전지의 구조 및 작동원리를 설명하고, 최근의 연구개발 및 산업동향을 소개하였다. Solar cells, converting directly light into electricity, can be categorized by materials comprising solar cells: inorganic-type and organic-type solar cells. Inorganic solar cells are composed of inorganic n-type and p-type materials such as silicon and compound semiconductors, where the structure of inorganic solar cell is typically built by pn junction. For the organic solar cells, there are two types: dye-sensitized solar cell and organic donor-acceptor solar cell. Dye-sensitized solar cell, consisting of nanocrystalline oxide film sensitized with dye molecule, redox electrolyte and metal counter electrode, is consideed as alternative to conventional solar cells due to its high solar-to-electricity conversiton efficiency (ca. 11%) and low cost. In this article, the structure, the operation principle and the recent R&D and industrial trends of dye-sensitized solar cells are discussed.

The purpose of this study is to analysis of difference between preferences and actual science teachers' an inquiry based instruction. Data were gathered though preferences questionnaire and practice questionnaire of the country from 363 science teachers. Preferences questionnaire and practice questionnaire were gathered different termination of question composed the same contents. Recognition for inquiry based instruction, student behavior, teacher behavior, data collection and inflection composed 4 categories, Likert 5 steps compared with difference preference and practice of each question. The results were as followings: First, teachers preferences inquiry based instruction and an practice condition of education came out meaningful of difference to inquiry based instruction(p<0.05). Also variable of teachers came out practice mean lower than preferences mean an inquiry based instruction. Accordingly, one of the reason haven't constituted to inquiry based instruction different preferences and practice. Second, especially student behavior in 4 categories of inquiry based instruction came out the lowest preferences mean and practice mean. Third, science teachers "they have to set up enough to scientific knowledge in relation to instruction" show up the highest preferences mean (4.5 point) to question "I have progressed to include to conceptual foundation of science" came out the highest practice mean (4.0 point) to question. On the other hand, teachers came out the lowest role of coagent and experiments with explain terms to preferences mean (3.6 point) as colleague researcher and institution came out the lowest practice mean (2.6 point) to question in relation to conduct of unity inquiry process. 본 연구의 목적은 탐구수업에 대한 과학 교사들의 선호와 실제 차이를 분석하기 위한 것이다. 탐구수업에 대한 인식,학생행동,교사행동,자료수집 및 활용 4개의 범주로 설문지를 구성 하였다. 과학교사들이 선호하는 탐구수업과 실제 교육현장에서 이루어지고 있는 탐구수업은 유의미한 차이가 있는 것으로 나타났다 (p<0.05). 또한 교사의 변인 모두에서 실제 평균이 선호 평균보다 낮게 나타났다. 따라서,탐구수업이 이루어지지 않는 이유 중 하나는 선호와 실제의 차이 때문이라 할 수 있다. 그리고 탐구수업의 4개 범주 중 특히 학생 활동에서는 선호와 실제의 평균이 모두 낮게 나타났다. 또한 과학 교사들은 ‘교사는 수업 내용에 관련된 과학적 지식 을 충분히 갖추고 있어야 한다’의 문항에서 선호 평균(4.5점)이 가장 높게 나타났으며 ‘나는 과학의 기본 개념’이 포함 ‘되도록 수업을 진행한다’의 문항 에서는 실제 평균(4.0점)이 가장 높게 나타 났다. 반면에,교사들은 수업에서 동료조사자로서의 역할과 직접 실험을 통한 용어 설명에서는 선호 평균(3.6점)이 가장 낮게 나타났다. 그리고 수업에서 학생들의 통합탐구과정의 수행에 관한 문항에서는 실제 평균(2.6점)이 가장 낮게 나타났다. 교사들이 탐구수업에 대한 의욕이 강해야 실제 수업에 반영될 수 있을 것이며 탐구수업은 결국 탐구를 가치 있게 여기는 교사에 의해 실천될 수 있다. 과학 지식과 함께 과학 과정과 기능을 과학 수업의 목표로 인식할 수 있는 탐구지향적인 교사 양성을 위한 교육과 학생틀을 탐구적인 방법으로 지도할 수 있도록 과학 교사에 대한 연수가 이루어져야 할 것이다.

Park,Yong-Jin,Cho,Gyu-Taek,Ma,Kyung-Ho,Lee,Sok-Young,Lee,Jung-Ro,Kim,Young-Chang,Cho,Eun-Gi,Kim Chang-Yung,Nam,Jung-Hyun,Rao,V,Ramanatha,Kang,Hee-Kyoung 한국자원식물학회 2004 Plant Resources Vol.7 No.2

Genetic background and phylogenetic relationships among 20 Korean wheat cultivars were assessed using microsatellites after amplifying with 13 SSR primer pairs. Average allele number per primer pair was 3.36. Genetic similarities for every pair of cultivars ranged from 0.42 to 0.97, with 0.69 of overall average. Korean cultivars were divided into two major groups based on microsatellite DNA polymorphisms. Group I consisted of relatively old cultivars developed until 1970s, and group II contained the recent cultivars developed during 1980s and 1990s. Amongst old elite cultivars/lines, ‘Yukseung 3’, ‘Norin 12’ and ‘Norin 72’ contributed most to the genetic background of cultivars belonging to group I, and ‘Norin 4’, ‘Norin 12’, ‘Norin 43’ and ‘Norin 72’ to group II, respectively. The phylogenetic relationship of Korean wheat cultivars was in accordance with the genealogical data of each cultivar. The genetic background of each cultivar was assessed from the point of breeding and germplasm management such as variety identification and duplicated accessions for assisting in developing a system for the registration of new variety based on the molecular characterization in future.

It has been hypothesized that jobs that have both high psychological demands and low decision latitude("job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome(MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model(16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects(n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-stain group, and OR of musculo skeletal disorder was 2.446(95% C. I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.
