본 연구에서는 문화체육관광부의 "관광사업체 기초통계조사" 자료를 이용하여 2009년부터 2013년 사이 충남지역 관광산업 종사자 수 및 매출액 구조 특성을 분석하였다. 기존 관광분야 국내외 변이할당분석 선행연구의 한계를 보완하기 위해 동태적 변이할당분석을 실시하였다. 분석 결과 충남지역 산업환경은 유원시설업 및 관광편의시설업의 종사자 수와 매출액을 증가시키는데 있어 다른 광역지자체 대비 경쟁력이 우수한 것으로 나타났다. 또한 최근 세종특별자치시 출범, 충남도청 이전 등 내부적인 환경변화가 충남지역 관광산업 종사자 수 및 매출액 증가에 영향을 미친 것으로 추정된다. 본 연구 결과는 효율적인 충남지역 관광산업 정책 수립을 위한 기초적인 정보를 제공할 수 있을 것으로 기대된다.

동합금 가두리망에 6개월간 사육한 조피볼락을 대상으로 동합금 가두리 망에서 유출되는 물질이 어류의 생존, 성장 및 건강도에 미치는 영향을 조사하였다. 대조구와 실험구간의 생존율과 성장률 그리고 혈액 성상은 유의한 차이가 없었으며(P<0.05), 간세포의 형태 및 간 조직 내에 존재하는 모세혈관과 담관의 구조가 특이적인 차이를 보이지 않았다. 구리와 아연 축적량은 실험 초기에 비해 증가하였지만 실험구와 대조구 간의 차이가 없었으며 허용기준치에 비해 매우 낮게 나타나 본 연구에 사용된 동합금망은 어류의 생존, 성장 및 건강도에 영향을 끼치지 않는 것으로 여겨진다.

본 연구는 종업원의 태도에 영향을 주는 직무특성을 확인하기 위하여, 인적자원관리의 관점에서 소상공인의 핵심직무특성(기술다양성, 과업정체성, 과업중요성, 자율성, 피드백)과 태도(직무만족, 조직몰입, 이직의도)간의 관계를 확인하는데 연구목적이 있다. 이러한 연구목적을 달성하기 위하여 국내 기업의 종업원 315명을 대상으로 소상공인의 핵심직무특성이 태도에 미치는 영향, 소상공인의 핵심직무특성과 태도간의 관계에서 성장욕구강도의 조절효과 등을 분석하였다. 회귀분석결과 기술다양성과 과업중요성은 직무만족에 정(+)의 영향을, 기술다양성과 피드백은 조직몰입에는 정(+)의 영향을 그리고 이직의도에 부(-)의 영향을 미치는 것으로 나타났고, 성장욕구강도의 조절효과는 과업중요성과 이직의도간의 관계에서만 발견되었다. 마지막으로 이러한 연구결과를 토대로 소상공인의 직무 태도 증진 방안과 경영전략적 시사점을 제시하였다.

Titanium-iso-propoxide[$Ti(OC_3H_7)_4$]와 Tetra-ethyl-lead $[Pb({C_2}{H_5})_4]$를 사용한 MOCVD법으로 PbTi$O_3$박막을 55$0^{\circ}C$에서 증착하였다. Ar과 $O_2$를 각각 운반 및 반응기체로 사용하였으며, 열처리에 따른 박막의 두께와 굴절지수의 변화, Xtjs 회절 분석, CV 특성 측정등을 행하였다. 열처리에 따른 CV 특성 측정 결과 PbTi$O_3$는 Si기판과 계면 반응을 하는 것으로 생각되며, X선 회절 분석 결과 $PbTiO_3$의 특성 peak들이 관찰되었다. 열처리 시간 및 온도의 증가에 따라 박막의 두께는 감소하고, 굴절지수는 증가하는 경향을 보여 주었다.

Rapid economic development has led seafood consumption to its quality - oriented pattern as well as consumer's in China. This study concerns about The First, China is Seafood development background. The Second, China become emboldened seafood causes. The third, seafood consumption has characteristic. The fourth, seafood consumption has the organization of society. The study shows that there are economic developmental periods Chinas has three time. The First time$(1961\sim1983)$ is rapid growth. The Second time$(1984\sim1998)$ is growth accumulate. The third time$(1999\sim)$ is changing on seafood consumption as the consumption of seafood is changed according to economic variables changes in income, price, tastes and population. This changing pattern of seafood consumption is based on economic variables appears toward luxury and convenience seafoods. Consumption of food is also affected by non - economic variables. The most typical non - economic variables leading to changes of seafood consumption is local, seafood culture, $et{\ldots}$ Recently seafood consumption pattern shows that consumers paying more money to get their seafood preference for pursuing its hight growth and varienty.

Certain malocclusion are associated with specific "facial type," and it is important for the clinician to classify the common facial characteristic of each patient. Because the reaction to treatment mechanics and the stability of the denture is depended upon the analysis of the facial pattern. Basically, there are 3 district facial types or patterns under which almost all malocclusion can be classified. 1. mesofacial is the most average growth. 2. brachyfacial which is a horizontal growth pattern has a week muscle, with dental arch, deep bite. 3. dolichofacial which is a vertical growth pattern has a strong muscle, narrow dental arch, open bite. Brachyfacial pattern show a resistant to mandibular rotation during treatment can accept a more protrusive denture and are prominantly nonextraction, whereas dolichofacial patterns tend to open during treatment require a more retracted denture in order to assure post-treatment stability. Brachyfacial pattern would better treat to use extrusive force system, whereas dolichofacial pattern treat to use intrusive force system with head gear and intermaxillary elastics.

A bioassay is a test system using a living organism (in whole or in part) to determine the presence or relative potency of chemical substances. The development and uses of bioassay are intimately linked to the discovery and characterization of the major classes of plant hormones. An application of this relationship is helpful for understanding the concept of plant hormones as well as the use of bioassay. And plant bioassay have been development and employed not only for the discovery and characterization of the biological activity of plant growth regulators but also have served several important secondary roles. The ideal bioassay should possess the characteristic of high specificity. great sensitivity. short response time, low cost and ease of obtaining plant material. acceptable ease of manipulation, and minimal space and equipment requirements.

The fractal geometry is a non-Euclidean geometry which describes the naturally irregular or fragmented shapes, so that it can be applied to fracture behavior of materials to investigate the fracture process. Fractal curves have a characteristic that represents a self-similarity as an invariant based on the fractal dimension. This fractal geometry was applied to the crack growth of cementitious composites in order to correlate the fracture behavior to microstructures of cementitious composites. The purpose of this study was to find relationships between fractal dimensions and fracture energy. Fracture test was carried out in order to investigate the fracture behavior of plain and fiber reinforced cement composites. The load-CMOD curve and fracture energy of the beams were observed under the three point loading system. The crack profiles were obtained by the image processing system. Box counting method was used to determine the fractal dimension, D$_{f}$. It was known that the linear correlation exists between fractal dimension and fracture energy of the cement composites. The implications of the fractal nature for the crack growth behavior on the fracture energy, G$_{f}$ is apparent.ent.

Synthesis of carbon nanofibers on a metal substrate by an ethylene fueled inverse diffusion flame was observed. Stainless steel plates were used for the catalytic metal substrate. The effects of radial distance and residence time of the substrate were investigated. The role of hydrocarbon composition in the fuel was also viewed. Nanofibers with a diameter range of 30-70nm were found on the substrate. The carbon nanofibers were formed and grown in the region from 4 to 5.5mm from the central axis of a flame outside of the visible flame front in the radial direction. The minimum residence time required for the formation of carbon nanofibers were about 20 seconds, and over 60 seconds were required for the full-scale growth. The characteristic time of the formation of carbon nanofibers was much shorter than that of the substrate temperature growth. In this study, the variation in hydrocarbon composition had no significant effect on the formation and growth of the carbon nanofibers.

Thecodiplosis japonensis is an important insect pest in pine trees and hard to be controlled by chemical pesticides due to its characteristic life cycle. Experiments were conducted to determine the pathogenicity and growth temperature of several entomopathogenic fungi as potential microbial insectcides for T. japonensis. Beauveria bassiana SFB-SC and Paecilomyces fumosoroseus SFP-198 were highly pathogenic against T. japonensis. B. bassiana SFB-SC had also pathogenicity against a beneficial insect Bombyx mori. Growth rate and pathogenicity of P. funmosoroseus SFP-198 under 15$^{\circ}C$ was higher than those of B. bassians SFB-SC. These results indicated that P. fumosoroseus SFP-198 is a potential microbial control candidate for control of T. japonensis.
