The cadmium contents of environment and human body were measured for the health status of the residents in the selected area near an old zinc-mining site assuming that cadmium contamination in the environment would affect the health status of the residents and the results were as follows: 1. The cadmium contents of the environment were 0.021±0.012 mg/m3 in the air. 0.019±0.011 mg/ml in the water, 0.382±0.233 mg/g in the rice and 0.342±0.211 mg/g in the tooth. 2. The major complaints of the residents were excessive sputum, dyspnea and pains on both extremities. F드믿 complained more frequently than male in dyspnea, lumbago and pains on both extremities. 3. An assessment of the nutritional health status of residents revealed that for male 8.5% were weak, 10.1% were fat and 32.5% were anemic, while for female 17.6% were weak, 15.3% were fat and 30.1% were anemic. 4. The prevalence rate of hypertension was 152.8?(male; 84.7?. female;200.0?) and the prevalence rate of diastolic hypertension was higher than that of systolic hypertension. 5. The diagnostic variables verifing the assumption mode in this study were blood pressure(0.76, p〈0.05) and E.S.R.(0.57, p〈0.01). From the above results, the environmental cadmium contamination affects the health status of the residents in the area near an old zinc-mining site to a certain extent, but not to a great extent(R2=0.55).

박종구 THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2004 Journal of biomedical laboratory sciences Vol.10 No.2

Massive identification of differentially expressed patterns has been used as a tool to detect genes that are involved in disease related process. We employed circular single stranded sense molecules as probe DNA for a DNA chip. The circular single stranded DNAs derived from 1,152 unigene cDNA clones were purified in a high throughput mode from the culture supernatant of bacterial transformants containing recombinant phagemids and arrayed onto silanized slide glasses. The DNA chip was examined for its utility in detection of differential expression profile by using cDNA hybridization. Hybridization of the single stranded probe DNA were performed with Cy3- or Cy5-labeled target cDNA preparations at 60℃. Dot scanning performed with the hybridized slide showed 29 up-regulated and 6 down-regulated genes in a cancerous liver tissue when compared to those of adjacent noncancerous liver tissue. These results indicate that the circular single stranded sense molecules can be employed as probe DNA of arrays in order to obtain a precious panel of differentially expressed genes.

The purpose of this paper is to observe and record Coaching behaviors of Judo Coaches and compare the difference between Judo Coaches by field. This study observed and recorded the coaching behaviors of 12 coaches (private hall 1 : 3, secondary school coach : 3, college coach : 3, national team : 3) complying with the standard of research subject and agreeing on the research intent of Judo coaches working for private hall, secondary and tertiary schools and national team located in Kyungin Region as of 2001 year by Coaching behaviors Observational Recording System (CBORS), and observational reliability coefficient was Scott's pl coefficient, over .90. As a in-depth interview to Judo Coaches' sports behaviors, the interview questionnaire used by Grossman (1990) and open type interview questionnaire made out based on precedented research was used. As for the collected data, percentage and frequency by the field of CBORDS coaching behaviors was compared by the field of Judo Coaches through systematic observational analysis, and the collected data through in-depth interview was analyzed using inductive category analysis. The authenticity of in-depth interview was confirmed by diverse analysis through members' review and expert groups' consultation. The observatory analysis and conclusion to Judo Coach Behaviors through the above method and procedure is as follows. First, there is difference in learning behaviors between Judo Coaches according to coaching field. National team coaches show significant difference to practicing time, middle and high school coaches show significant difference in coaching time, and college coaches show difference in operation time, and social sports coaches show significant difference in stand-by time. Second, there is difference in interactional behaviors among Judo Coaches according to coaching field. National team coaches was indicated to perform interactions by simplifying the experimented as individuals rather than diversified interactions at interactions with trainees. Third, there is difference in coaching behaviors among coaches by coaching field. At the coaching behavior of sub-areas of coaching behavior areas, social sports coaches was the highest in coaching time ratio, while there is any remarkable difference between national team and middle and high school coaches. At the demonstrating behavior of sub-areas of coaching behavior areas, national team coaches were the highest in coaching time ratio. At the social behavior of sub-areas of coaching behavior areas, social sports coaches was the highest in coaching time ratio. Middle and high school coaches were indicated to use trainee's voluntary depressible physical punishment for the effective progress of classes. And social sports coaches and national team coaches were indicated to use praise as social behavior. At the encouraging behavior of sub-areas of coaching behavior areas, college coaches were the highest. Especially, coaches with less experienced in coaching performed pressing behavior during coaching hour, but they were aware that coaching behaviors to be ultimately pursued are encouraging behaviors. At the technical feed-back behavior of sub-areas of coaching behavior areas, national team coaches were the highest. Al1 coaches provided positive feed-back for trainees, especially corrective feedback has been provided by national team coaches. At non-coaching behavior of sub-areas of coaching behavior areas, national team coaches were the lowest, and the absence status of coaches by outside figures during classes. suggests the need of more responsible and independent classes.

戰略的 經營을 爲한 生産戰略의 內容

The enterprise can grow up and continue to exist, when it pursues the business strategy which properly copes with the management condition and the change of industrial structure. As the business strategy is a means of attaining the goal of the enterprise, it is an all-out plan containing all parts for long - term purposes, and it is a king of operation which harmonizes supply of resources with distribution. As the ultimate goal of the business strategy lies in having an advantage over a rival company, the substances of the competition strategy are a differentiation and an advantage and a focus strategy. The cost leadership strategy can minimize costs and make profits above the average through effective economy, accumulation of experience, cartailment of indirect cost and an outlay for advertisement. However, the cost leadership strategy can't disregard the quality of the goods and service. As the differentiation strategy has an advantage over a rival company through the quality of the goods and the design based on up - to- data technology, it can also make profits above the average in business. Even by the differentiation strategy, the advantage in cost can't wholly be disregarded. But only in the order of priority, the differentiation strategy gets the lead.. While the subject matters (substances) of the business strategy are a long - term object of the enterprise and a distribution of resources, the production strategy is a long - term goal that the production parts pursue. The goals of the production fields are productivity, delivery, quality, delivery speed, adaptability, design and so on. As these subjects are related to "trade off", the establishment of the subject on the order of priority is required. In other words, when the competition strategy of the enterprise consists in the advantage in cost, the goal of the production part lies in productivity and efficiency. And when the enterprise pursues the differentiation of the competition strategy, the object of the production part lies in quality, adaptability, diversification and design. In the courses of all the policy decisions, the competition strategy and the production strategy as a goal of part must be kept consistent and be harmonized.

재조합 아데노 바이러스 생산을 위한 효과적인 Shuttle 벡터의 개발과 검증

박종구 啓明大學校 醫科大學 1998 계명의대학술지 Vol.17 No.4

Recombinant adenovirus is an attractive vehicle to deliver a foreign gene for the virus can infect many cell types including non-dividing cells. Production of a recombinant adenovirus requires co-transfection of a shuttle vector which harbors a gene of interest and a rescue vector. Adenoviral shuttle vectors currently in use contain limited numbers of cloning sites for insertion of a foreign gene. They also lack a promoter and a signaling sequence for the poly(A) tail. Therefore, we set out to construct two adenoviral shuttle vectors, pAd-YC and pAd-YC2, in an effort to facilitate cloning and expression of foreign genes. pAd-YC contains the CMV promoter and multiple cloning sites but without a poly(A) signal sequence. pAd-YC2 contains the CMV promoter, the multiple cloning sites and the poly(A) signal sequence. The functionality of pAd-YC and pAd-YC2 was tested by cloning and expression of a chimeric Fcγreceptor cDNA and the β-galactosidase gene. Fcγreceptor expression was confirmed by binding of opsonized erythrocytes to COS-1 infectants, and β-galactosidase expression was assayed for X-gal staining. The results demonstrate the functional efficacy of the two shuttle vectors. We have since successfully constructed several recombinant adenoviruses by employing the two versatile shuttle vectors.

Novel Trimeric Complex for Efficient Uptake of Plasmid Vector into HepG2 Cells

박종구,-- THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2003 Journal of biomedical laboratory sciences Vol.9 No.2

Viral and :ion-viral vectors have been used in the delivery of genetic materials into animal cells and tissues, with each approach having pros and cons. Non-viral vectors have many useful merits such as easy preparation, low immunity and size tolerance of a transgene when compared to those of viral vectors. Delivery specificity may be achieved by complex formation between receptor ligands and a non-viral vector. In the present study, non-viral vector systems are investigated in an effort to find a practical delivery means for gene therapy, Receptor-ligand interaction between transferrin-receptor and transferrin was utilized for efficient gene transfer into cancer cells. A plasmid vector, pcDNA3 (LacZ) was ligated with a small duplexed oligo fragment in which a Biotin-VN^(TM) phosphoramidite was placed in the middle of the oligo. The plasmid vector labeled by biotin was then conjugated with biotin-labeled transferrin via streptavidin. This trimeric conjugates were delivered to a hepatoma cell line, HepG2. The delivery efficiency of the trimeric conjugate was 2-fold higher than that of cationic liposomes used for transfection of a plasmid vector. These results demonstrate that a plasmid vector can be efficiently transferred into cells by forming a trimeric complex of plasmid vector-linker-ligand.
