The purpose of this study was to expand the utility of the Polygonum multiflorum. Also, we fermented P. multiflorum by mushroom mycelial, and analyzed for chemical compositions and biological active of fermented P. multiflorum root. The crude protein content did not show a significant difference between control and fermented P. multiflorum root, crude fat, ash and crude fiber content of fermented P. multiflorum root were lower than control. The content of soluble nitrogen free extract of P. multiflorum root was significantly higher than fermented P. multiflorum root. The major amino acids of P. multiflorum root were determined the arginine. The content of arginine and glutamic acid were 586.67 mg%, and 283.78 mg%, respectively. Sixteen kinds of amino acids were detected in fermented P. multiflorum root, and the major amino acids were determined the arginine and threonine. The total amino acid contents of control and fermented P. multiflorum root were 3,469.03 mg%, and 3,630 mg%, respectively. As the results of antioxidant activity test, the antioxidant capacity of fermented P. multiflorum had a higher than the control. As the mushroom fermentation progresses, it is confirmed that the amino acid content and antioxidant capacity were increased, and it is expected to develop the product using the fermented P. multiflorum using mushroom mycelials.

목 적: 본 연구는 제5기 국민건강영양조사(2012) 자료를 이용하여 한국 성인의 건성안 유병률과 위험요 인을 알아보고자 하였다. 방 법: 19세 이상 성인 중 안과의사에게 건성안 검진을 받은 5,698명(남자 2,368명, 여자 3,330명)을 대 상으로 인구사회학적 특성, 전신질환 특성, 건강관련행위 특성에 따른 건성안의 유병률과 위험요인을 분석 하였다. 결 과: 전체 연구대상자의 건성안 유병률은 13.5%이었다. 인구사회학적 특성별 건성안 유병률은 남성보 다 여성이, 50세 미만군보다 50세 이상군이, 농촌지역보다 도시지역에서 통계적으로 유의하게 높았으며, 전 신질환별 건성안 유병률은 고혈압, 이상지혈증, 골관절염, 류마티스 관절염, 우울증, 신부전증이 있는 경우 에 유의하게 높았다. 건강관련행위별 건성안 유병률은 비흡연자, 비음주자, 수면시간이 짧은 군이 높았다. 건성안 빈도는 여성에서(OR 2.29, CI 1.89-2.77)와 50세 이상군에서(OR 1.21, CI 1.01-1.46), 농촌지역에 서(OR 1.96, CI 1.56-2.47)에서 더 높았다. 유의한 모든 변수를 보정한 후에 건성안의 위험인자는 신부전 (OR 2.82, CI 1.48-5.69), 갑상선(OR 1.62, CI 1.16-2.26), 류마티스 관절염(OR 1.54, CI 1.01-2.33), 이상 지혈증(OR 1.42, CI 1.13-1.78), 우울증(OR 1.36, CI 1.11-1.66), 골관절염(OR 1.27, CI 1.02-1.57)이었다. 결 론: 우리나라 19세 이상 성인의 건성안 유병률은 13.5%으로 높은 수준이며, 50세 이상, 도시지역 거 주자, 여성과 신부전증, 갑상선, 류마티스 관절염, 이상지혈증, 우울증, 골관절염 환자에서 건성안의 위험이 높으므로 해당 위험요인을 가진 사람들을 대상으로 한 교육과 홍보를 통해 건성안증상을 조기 발견하여 적 절하게 대처하도록 할 필요가 있다

Nano sized FeAl intermetallic particles were successfully synthesized by plasma arc discharge pro-cess. The synthesized powders shouted core-shell structures with the particle size of 10-20 nm. The core was metallic FeAl and shell was composed of amorphous Because of the difference of Fe and Al vapor pressure during synthesis, the Al contents in the nanoparticles depended on the Al contents of master alloy.

Iron-carbon nanocapsules were synthesized by plasma arc discharge (PAD) process under various atmosphere of methane, argon and hydrogen gas. Characterization and surface properties were investigated by means of HRTEM, XRD, XPS and Mossbauer spectroscopy. Fe nanocapsules synthesized were composed of three phases with core/shell structures. The surface of nanocapsules was covered by the shell of graphite phase in the thickness of nm.

이 연구는 일반적인 인지이론을 조종사 기술의 범위로 확대시켜, 조종사가 얼마나 빠르고 정확하게 상황인식을 하는지를 제시문과 비행 장면 일치성 측정을 통해 알아보았다. 이 연구의 목적은 두 가지 측면의 변인에 따라 상황인식이 전문성의 영향을 받는지를 알아보는 것이다. 비행 요소간의 관계를 나타내는 비행 상황 변인들과 비행 요소의 내용을 나타내는 비행 상황 변인들 모두 비행 상황인식에 영향을 주었다 그리고 작업기억은 다양한 정보들을 통합시키는 데 결정적인 역할을 하는 것으로 나타났다. 이러한 결과는 비행 상황인식의 바탕인 인지적 과정을 나타내는 구조화통합 모델의 이론적 틀 안에서 설명되어진다.

This study is designed to analyze the production, employment, value added and income impacts tha, in the event of designation and development of Haeundae as 'Convention, Movie, Marine Leisure Special Zone', its marine sector would have on the local economy. The realization of marine leisure special zone of Haeundae in Busan is expected to lead to a direct and indirect investment of approx. \13.6 billion, resulting in \68.0 billion in production impact, 850 jobs in employment impact, \28.0 billion in value added impact and \14.5 billion in income impact. This is expected to give a boost to a stagnant local economy, offering opportunities for the revival of Busan's tourist industry.

A theme park is a tourism destination attracting a lot of tourists. Many local authorities establish theme parks within their own territory. Busan Metropolitan City tries to host an attractive theme park, and to make the city known as the tourism destination for 21st century. The purpose of this paper is to suggest a policy and management strategy of theme park based on questionnaire analysis for international tourists visiting Busan. First, it is needed to supply low land price to reduce construction cost and to attract investors from the public and private sectors. Second, the theme park has to have attractive themes and new events for repeaters. Third, infra structures related to the theme parks should be provided for the easy accessibility. Finally more emphasis should be placed on public relation and service education for employees.
