김영호,이선근,김신혜,송윤주,정주영,박미정,Kim, Young-Ho,Lee, Sun-Gun,Kim, Shin-Hye,Song, Yoon-Ju,Chung, Ju-Young,Park, Mi-Jung 대한소아소화기영양학회 2011 Pediatric gastroenterology, hepatology & nutrition Vol.14 No.2

목적: 한국 영유아의 영양 섭취 실태에 대한 연구가 매우 제한적으로 진행되고 있어, 본 연구에서는 국민건강영양조사를 이용하여 한국 유아들의 식이 행태, 식이보충제 및 영양소 섭취 실태를 알아보고자 하였다. 방법: 2007~2009년까지의 제4기 국민건강영양조사에 참여한 4세 미만의 영유아 930명(남 499명, 여 431명)을 대상으로 영아기의 식이 행태, 식이보충제 및 영양소 섭취 실태를 조사하였다. 결과: 식이보충제를 복용하는 유아는 48.7%로 절반가량이었으며 비타민/미네랄제가 35.3%로 제일 많았고 정장제 14.2%, 초유 8.2%였다. 식이보충제를 시작한 동기로는 95.4%가 친척이나 친구의 권유로, 0.7%가 자신의 판단으로 보충식을 시작했다고 답하였으며 의사의 권유로 보충제를 시작하는 비율은 0.3%에 불과하였다. 영양소 섭취 조사에서 유아의 51.6%는 탄수화물의 적정 비율을 섭취하고 있었고 32.7%가 적정 비율을 초과하여 섭취하고 있었다. 단백질의 경우 대상아의 94.8%가 적정 비율을 섭취하고 있었고, 지방의 경우 53.4%는 적정 비율을, 38.8%는 적정 비율 미만을 섭취하고 있었다. 칼슘을 평균필요량 미만으로 섭취하는 유아의 비율은 1세 53.9%, 2세 55.2%, 3세 65.6%, 철을 평균 필요량 미만으로 섭취하는 유아는 1세 52.0%, 2세 48.7%, 3세 48.4%였다. 영아기의 수유 패턴은 혼합 수유가 57.4%로 제일 많았고 32.2%가 모유 수유만, 10.4%가 분유 수유만을 하고 있었다. 이유식 도입시기는 4~6개월이 64.5%로 가장 많았고, 우유 도입시기는 12~17개월이 71.1%로 가장 많았다. 결론: 우리나라 만 1~만 3세 이하 유아의 절반가량이 의사의 상담 없이 식이보충제를 복용하고 있었으며, 칼슘, 철 섭취가 부족할 위험이 높았다. 이 시기의 영양관리를 위해 소아청소년과 의사를 비롯한 전문가의 역할이 보다 강조될 필요가 있다. Purpose: The aim of this study was to investigate the feeding patterns, use of dietary supplements, and nutrient intake of Korean toddlers. Methods: We used data for 930 toddlers who participated in the 4th Korean National Health and Nutrition Examination Survey (KNHANES) from 2007 to 2009. Feeding patterns and use of dietary supplements were assessed using standardized questionnaires, and nutrition intake was assessed using the 24 hr recall method. Results: In 2007~2009, 48.7% of toddlers used dietary supplements. Most parents (95.4%) initiated a regime of dietary supplements for their children following the advice of friends or relatives. Only 0.4% of parents followed the advice given by their doctors for dietary supplements use. In the survey of nutrient intake for toddlers, the prevalence of inadequate calcium intake was 53.9% for subjects aged 1 year, 55.2% for 2 years and 65.6% for subjects aged 3 years. The prevalence of inadequate iron intake was 52.0% for subjects aged 1 year, 48.7% for 2 years and 48.4% for subjects aged 3 years. In the survey performed on feeding patterns of toddlers during the infant period, mixed feeding accounted for 57.4%, breast feeding for 32.2%,and formula feeding for 10.4%. Sixty-five percent of toddlers began weaning between 4 and 6 months. Conclusions: This study indicated that a number of toddlers were at risk of inadequate calcium and iron intake. The role of professionals in counseling for qualified dietary intake and dietary supplement use is therefore necessary for Korean toddlers.

경제 발전에 따라 레저, 해운, 수산, 국방, 해난사고 등 해양을 이용하는 활동이 증가하면서 해양예보에 대한 수요가 크게 증가하고 있다. 기상에서 해양의 역할이 새롭게 인식되면서 정확한 기상 및 기후변화를 예측하기 위한 해양 예측의 필요성도 증가하고 있다. 사회적인 요구와 관련 기술의 발전에 힘입어 선진국을 중심으로 해양예측시스템이 수립되어 왔다. 이 연구에서는 세계적으로 해양예측시스템을 발전시키고 확산시킨 국제협력프로그램 GODAE(Global Ocean Data Assimilation Experiment)의 진행과정과 기여를 정리하였다. 그리고 현재 해양예측시스템을 운용 중인 미국, 프랑스, 영국, 이탈리아, 노르웨이, 호주, 일본, 중국이 해양예측시스템을 구축하면서 세웠던 목적과 비전, 역사, 연구 동향을 조사하고 각 나라의 해양예측시스템 현황을 비교하였다. 우리보다 앞서 해양예측시스템을 구축하여 사용하고 있는 나라들이 취한 개발 전략의 특징은 다음과 같이 요약해 볼 수 있다. 첫째, 국가적인 역량을 집중하여 성공적인 현업 해양예측시스템을 구축하였다. 둘째, 국제적인 프로그램을 통해 선진 기술을 공유하고 상호 발전시켰다. 셋째, 각 기관의 역할과 고유 목적에 따라 기여분야를 나눠가졌다. 국내에서도 최근 현업 해양예측시스템에 대한 수요가 증대되고 있다. 기상청, 국립해양조사원, 국립수산과학원, 국방과학연구소의 해양예측시스템 개발에 관한 현재 상황과 향후 장기적 계획을 조사하였다. 국지 해양예측 또는 기후예측 모델을 위한 개방경계 초기장 제공이 가능한 광역의 정확도 높은 해양예측시스템을 구축하기 위해서는 국내의 유관 기관 간 협력 관계가 필수적이다. 이를 위해 관련 기관과 연구자들이 함께 참여하는 컨소시엄 형성이 바람직하다. 컨소시엄을 통해 경쟁력 높은 예측 모델과 시스템을 구축할 수 있으며, 제한된 재원을 효율적으로 활용할 수 있고, 연구 개발 인력이 전문분야에 집중할 수 있으며, 중복 투자를 막고 각 기관은 고유 업무에 역량을 집중할 수 있다. 비록 해양예보에 있어 우리나라가 현 단계로는 국제적인 수준에 뒤쳐져 있지만, 각 유관 기관들이 고유 업무를 정립하고 국가적인 역량을 집중하여 현업 해양예측시스템을 공동 개발하면 곧 추격하여 해양예보 분야를 선도할 수 있을 것이다. National demands for the ocean forecasting system have been increased to support economic activity and national safety including search and rescue, maritime defense, fisheries, port management, leisure activities and marine transportation. Further, the ocean forecasting has been regarded as one of the key components to improve the weather and climate forecasting. Due to the national demands as well as improvement of the technology, the ocean forecasting systems have been established among advanced countries since late 1990. Global Ocean Data Assimilation Experiment (GODAE) significantly contributed to the achievement and world-wide spreading of ocean forecasting systems. Four stages of GODAE were summarized. Goal, vision, development history and research on ocean forecasting system of the advanced countries such as USA, France, UK, Italy, Norway, Australia, Japan, China, who operationally use the systems, were examined and compared. Strategies of the successfully established ocean forecasting systems can be summarized as follows: First, concentration of the national ability is required to establish successful operational ocean forecasting system. Second, newly developed technologies were shared with other countries and they achieved mutual and cooperative development through the international program. Third, each participating organization has devoted to its own task according to its role. In Korean society, demands on the ocean forecasting system have been also extended. Present status on development of the ocean forecasting system and long-term plan of KMA (Korea Meteorological Administration), KHOA (Korea Hydrographic and Oceanographic Administration), NFRDI (National Fisheries Research & Development Institute), ADD (Agency for Defense Development) were surveyed. From the history of the pre-established systems in other countries, the cooperation among the relevant Korean organizations is essential to establish the accurate and successful ocean forecasting system, and they can form a consortium. Through the cooperation, we can (1) set up high-quality ocean forecasting models and systems, (2) efficiently invest and distribute financial resources without duplicate investment, (3) overcome lack of manpower for the development. At present stage, it is strongly requested to concentrate national resources on developing a large-scale operational Korea Ocean Forecasting System which can produce open boundary and initial conditions for local ocean and climate forecasting models. Once the system is established, each organization can modify the system for its own specialized purpose. In addition, we can contribute to the international ocean prediction community.

김영호,김재열,Kim, Young-Ho,Kim, Jae-Yeol 한국공간구조학회 2011 한국공간구조학회지 Vol.11 No.3

ETFE막재는 PTFE막재에 비해 상대적으로 두께가 매우 얇고 유연하기 때문에 다양한 온도환경에 따른 막재의 재료특성을 알아볼 필요가 있다. 본 논문에서는 ETFE 막재에 대해 다양한 온도하에서의 재료특성 실험을 수행하였다. 첫째로, -20$^{\circ}C$, 0$^{\circ}C$, +20$^{\circ}C$, +40$^{\circ}C$ 하에서 각각 5 시험편을 이용하여 인장실험을 수행하였으며, 각 온도하에서의 항복응력, 인장강도, 영계수를 도출하였다. 두 번째는, 25$^{\circ}C$, 40$^{\circ}C$, 60$^{\circ}C$ 하에서 각각 3MP, 6MP, 9MP의 하중을 가하여 각 온도에 따른 크리프 변형도를 알아보았다. 마지막으로, -15$^{\circ}C$, 0$^{\circ}C$, 20$^{\circ}C$ 하에서의 인열강도 시험을 수행하였다. 시험결과분석에 따르면, ETFE막재의 전제적인 거동은 크게 변하지 않았으나, 재료특생은 온도의 영향을 받고 있음을 알 수 있었다. It is needed to investigate the material properties of ETFE foil under various temperatures because ETFE membrane foils have very thin depth and relatively high flexibility. In this paper, the material properties of ETFE membrane foil obtained from 3 testes under various temperatures are presented. First, the uniaxial test under four temperatures as -20$^{\circ}C$, 0$^{\circ}C$, +20$^{\circ}C$ and +40$^{\circ}C$ was performed. Each 5 specimen was tested and the yield stress, tensile strength and the Young's modulus of the foils are obtained. Second, the creep testes under three temperatures as 25$^{\circ}C$, 40$^{\circ}C$ and 60$^{\circ}C$, 3MP, 6MP and 9MP tension load was subjected to the specimen and the creep characteristics was investigated. Finally, the tear test under $5^{\circ}C$, $^0{\circ}C$ and $20^{\circ}C$ was performed. It is concluded that the shape of stress-strain curve or general behaviors are similar with that of normal temperatures but the mechanical characteristics of ETFE membrane foils were affected by the temperatures, obviously.

김영호,최영복,정성훈,홍필영,문동찬,김선태,Kim, Young-Ho,Choi, Young-Bok,Chung, Sung-Hoon,Hong, Pil-Young,Moon, Dong-Chan,Kim, Sun-Tae 한국전기전자재료학회 1998 전기전자재료학회논문지 Vol.11 No.7

Thin film deposition of InN, which is a less-studied III-nitride compound semiconductor because of the difficulty if crystal growth, was performed by rf reactive sputtering method using In target and $N_2$reactive gas. The structrual, electrical, and optical properties of the produced films were measured and disussed according to the sputtering parameters such as deposition pressure, rf power, and substrate temperature. From the result of deposition pressure, rf power, and substrate temperature, we could obtain optimal conditions of 5m Torr, 60W, $60^{\circ}C$ for preparing InN thin film with high crystallinity, low carrier concentration, and high Hall mobility. The carrier concentration, Hall mobility, and optical bandgap of the fabricated InN thin films at optimal condition were $6.242\times10^{18}cm^{-3}, 212.526cm^2/V\cdot$s, and 1.912eV, respectively.

Puromycin Aminonucleoside 투여로 인한 사구체 족세포의 초미형태학적 변화

김영호,박관규,김영만,조수열,Kim, Young-Ho,Park, Kwan-Kyu,Kim, Young-Man,Cho, Soo-Yeul 한국현미경학회 1998 Applied microscopy Vol.28 No.4

Puromycin aminonucleoside (PAN) nephropathy was induced in a group of Sprague-Dawley rat by a single dose of intraperitoneal Injection to study an ultrastructural change of glomerulus. The experimental rats developed proteinuria three days after PAN injection. Electron microscopic studies of glomeruli showed the loss of epithelial foot processes, formation of cytoplasmic vacuoles, microvillous formation and increased numbers of lysosomes in the cytoplasm of podocytes. It is strongly suggested that proteinuria in PAN nephrosis may be primarily due to a glomerular epithelial lesion, leading to focal disarray of anionic sites or focal defects in the epithelial covering of the basement membrane. The loss of anionic sites in the basement membrane nay be caused by the foot process fusion and the epithelial detachment from the basement membrane.
