Objective: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases Methods: l l hospital participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. Results: Between April 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. most of the HAVS cases came from shipbuilding, and 172 of them (92.7%) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9%). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6%) and 4 (12.1%) cases of occupational asthma, the agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10(58.8%) of the cases were diagnosed as squamous cell carcinoma and 5(29.4%) as adenoma. Conclusion: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

최영철(Choi, Young-Cheol),박현준(Park, Hyunjun) 한국경영교육학회 2020 경영교육연구 Vol.35 No.6

[연구목적] 본 연구에서는 제조환경의 패러다임 변화 속에 새로운 성장동력으로 스마트 팩토리를 도입한 기업의 경영자원을 분석하여 핵심역량을 파악하고 기업 전반에 미치는 영향을 진단, 시사점을 제공하고자 하였다. [연구방법] 2015년 이후 스마트팩토리를 도입한 포스코를 연구대상으로 선정하고, 자원기반관점에 의거 기업 내부역량 분석에 유용한 VRIO Framework를 통해 스마트팩토리에 영향을 받은 경영자원 분석과 핵심역량을 도출하였다. 또한, 이 핵심역량이 경영성과에 어떠한 영향을 미치는지에 대한 부분도 검토하였다. [연구결과] 포스코 스마트팩토리의 영향을 받은 경영자원을 VRIO 분석한 결과 7개 핵심역량을 도출하였고, 이 핵심역량의 효과로 생산성 향상, 설비고장 비가동율 최소화, 불량률 및 품질 실패비용 감소, 납기준수율, 생산계획 증대로 인한 에너지 비용 절약 등을 통해 재고비용 합리화, 매출액 증대, 비용 절감을 통한 이익 증대, 부가가치 창출, 기업의 가치 극대화 등의 재무적 성과도 거두고 있음을 확인하였다. [연구의 시사점] 스마트팩토리의 도입은 기업이 지속 가능한 경쟁우위를 갖게 하여 핵심역량으로 발전시키며 기업의 성과에 큰 역할을 하지만, 각 기업만의 고유 특성을 고려하여 기업의 대내외자원과 기업의 주변 환경을 결합한 실증연구도 필요하다. [Purpose] In this study, we tried to analyze the management resources of companies that introduced smart factories as new growth engines amid a paradigm shift in the manufacturing environment to identify core competencies, diagnose their impact on the enterprise as a whole, and provide implications. [Methodology] Through VRIO Framework, management resource analysis and core competencies affected by POSCO Smart Factory were derived. It also considered how these core competencies affect management performance. [Findings] The analysis of the management resources affected by POSCO Smart Factory resulted in seven core competencies. It confirmed that the effects of these core competencies have also resulted in financial performance, such as rationalizing inventory costs, increasing sales, creating value-added, and maximizing corporate value. [Implications] The introduction of smart factories plays a significant role in companies’ performance by making them have a sustainable competitive advantage and developing them into core competencies. Still, it is also necessary to conduct empirical studies that combine the companies’ internal and external resources with the environment surrounding.

In this study, a vehicle vector using cryptic plasmids was constructed for gene transfer in Helicobacter pylori. pHP51(3.9 kb) and pHP489(1.2 kb) were selected for constructing vectors from cryptic plasmid of H. pylori isolates in Korea. The HindⅢ-digestedDNA fragment(1.2kb) of pHP489 and 1.6kb DNA fragment of pHP51 were ligated with a kanamycin resistance gene(aph3'-Ⅲ) from C. jejuni to produce the recombinant plasmids pHP489K and pHP51K, respectively. Transformation frequency of pHP51K by electroporation was low. But pHP489K could be effectively transformed into various H. pylori strains. In order to design an intermdiate vehicle vector for gene transfer into H. pylori, pBlueHP489K was prepared by recloning pHP489K DNA into pBluescript and pTZ19R vector. This vector permitted the DNA fragment containing pHP489 sequence, aph3'-Ⅲ, and cloned DNA to be cut and self-ligated in the SacⅠ site after cloning. ureA and ureB gene were inserted into pBlueHP489K, resulting in pBlueHP489K/AB. The DNA fragment containing pHP489, kanamycin resistance gene(aph3'-Ⅲ), and urease structural gene was cut away from pBlueHP489K/AB and self-ligated to generate pBlueHP489K/AB. pBlueHP489K/AB made urease-negative H. pylori strains restore their urease activity. By this experiment, pBlueHP489K was confirmed to be the vehicle system for transferring H. pylori genes.

In this study, silicon nitride was fabricated from sludged silicon powders with nitrogen gas. Silicon nitride whiskers were synthesized from sludged silicon powders by heat-treating at 1200, 1300, and 1400℃ for several hours. Silicon nitride whiskers of variety size were fabricated, and these were well synthesized at higher temperature. Characteristics of the fabricated silicon nitride was analized by XRD and SEM.

The purpose of this study was to observe the effects of 12 weeks weight training on Body composition and Strength. The healthy male in che ju are randomly selected as subjects. The procedure of this experiment are as follows. 20 subjects are divided into two groups : G - 1 (High load - 10 Reps) , G - 2 (Low load - 20 Reps). All two groups trained for 12 weeks: Monday, Wednesday, Friday. During each workout following lifts are used : Bench press, Leg press, Barbell curl. Lat pull-down, Standimg press, Triceps extension, Dumbbell fly and Sit-up. The conclusion were as follows: 1. Changes of physique of before and after training. Body weight, chest girth, bicep girth did not increase significantly in G - 2 but Body weight (3.4 %) , chest girth (3. 0%) , bicep girth (2. 4%) and thigh girth (2. 7%) increased significantly (P < 0.05) in G - 1. 2. Changes of body composition of before and after training. % Fat and Fat weight did not decrease significantiy in both groups. Lean body mass did not increase significantiy in G-2, but increased (4.2%) significantly (P < 0.05) in G - 1. 3. Changes of muscular strength of before and after training. Hand grip (left, right), back muscle strength, bench press and lgg press incresd(P <0.001) significantly in both groups. but high load group (G - 1) slightly more incresed than in low load group (G-2).

To develop World Wide Web servire of Cyber Insect Garden(CIG) linked with database, we col-lected ecological information data of insect and host plant. This site can be accessed easily by the general public. Insects and host plants can be linked with various scenes and seasons. CIG was the first site developed in Korea and its Web site address is http://www.mast.go.kr/cig. As database information consist of text data and images of insects and host plants for the general public, we access to lots of ecological insects and host plants informa-tions. Therefore, all netizens can experience them indirectly and feel their childhood homesickness.

Openings through beams are required for the passage of utility ducts and pipes, and they are freqently encountered in the design of modern buildings. They are particularly important in multistory buildings where the use of openings in beams can mean lower story heights, leading in turn to a multiplicity of savings. Therefore, the designers are often faced with the necessity of providing adequate openings in the buildings. However, provision of openings may cause problems of excessive cracking and deflection, and may severly affect the strength of a beam. An experimental investigation is carried out on twelve reinforced concrete beams with square openings. The size of opening, and it's location are considered as major variables. The specimens were tested under two point loading. Loads were usually applied in steps of 0.5 ton up to failure to observe the crack initiation and propagation, initial diagonal cracking, midspan deflection, concrete strain and reinforcement strain.
