최근 들어 리얼 버라이어티가 TV 프로그램의 주를 이루면서 인체 기관에 자극을 주는 다양한 음식을 먹는 것이 게임에 등장하고 있다. 특히, 까나리액젓이나 레몬 빨리 씹어 먹기 등 인체에 자극을 주는 벌칙 게임들이 펼쳐지고 있다. 레몬은 모든 독의 해독제라고 할 만큼 우리 몸에 이로운 점이 많으나 과하거나 급할 경우 오히려 병이 될 수도 있다. 따라서 본 논문에서는 대체 및 예방의학에 이용되는 중요한 요소 중 하나인 식이요법에 대한 효능을 입증하기 위한 방법으로 음성신호 분석 기술을 적용하여 레몬 섭취에 따른 성대 진동의 변화를 측정하고 이에 대한 분석을 통해 레몬과 음성과의 관계를 규명하는 연구를 수행하고자 한다.

인간의 본능적인 욕구 중 생리적 욕구는 생존을 위해서 불가결한 것 중 하나이며 이러한 생리적 요구엔 성욕이 포함되어 있다. 성욕은 외부자극으로 인하여 욕구가 충동되며 도파민과 테스토스테론의 호르몬 분비가 일어나 성적 충동을 증가시켜 신체변화에 영향을 미친다. 따라서 본 논문에서는 성욕을 자극하여 성적 충동이 증가되었을 때 목소리의 변화를 분석하는 연구를 수행하였다. 이를 위해 성적 충동이 증가되기 전과 후의 음성을 수집하고 성대 관련 음성분석 요소인 Pitch, Intensity 기술을 적용하여 변화된 음성의 특징을 추출하였다.

Cu-Zn-Al catalysts were prepared via co-precipitation method for low-temperature water-gas shift (LT-WGS) reaction under practical reaction condition. Aging time was systematically changed to find optimum point for LT-WGS under practical condition. The Cu-Zn-Al catalyst aged for 72 hours showed the highest CO conversion within low-temperature range as well as very stable catalytic activity for 200 hours despite the practical reaction condition.

This study was carried out to investigate effect of irradiation doses on quality of vacuum-packed dry-cured ham during storage. Dry-cured pork slices were vacuum-packaged in nylon/ polyethylene bags. Vacuum-packed dry curd pork was stored at $10{^{\circ}C}$ for 12 weeks after irradiation (0 kGy, 2.5 kGy, 5 kGy, 7.5 kGy and 10 kGy) and physicochemical properties of dry curd porks, such as meat color surface, thiobarbituric aicd reactive substances, volatile basic nitrogen, pH, microbial (total plate count, Lactobacillus) and sensory properties (color, flavor, overall acceptability) were investigated. Irradiation treatment decreased a*-value, TPC and Lactobacillus. Irradiation dose significantly (p<0.05) increased irradiation flavor and TBA value. However, irradiation dose decreased redness and sensory color in dry-cured ham. The quality of dry-cured ham was affected by the irradiation dose. The results suggested that dry-cured ham irradiated at 5 kGy dose may show optimum quality characteristics of the products as well as microbial safety.

A total of one hundred twenty pigs were used to investigate effects of silage feeding on pork quality among three breeds (Gagoshima Berkshire, American Berkshire, $LY{\times}\;D$). Pigs weighing about 70 kg of body weight were randomly alloted into three breeds [B (Gagoshima Berkshire), D $(LY{\times}\;D)$, A (American Berkshire) by two dietary treatment [C (commercial diet feed) and T (commercial diet with 80% silage)]. All pigs were fed 67 days of period and then slaughtered to examine meat characteristics. A chemical compositions and physico-chemical characteristics were measured in pork loin. The crude protein content was higher in pig fed diets containing silage than that of the control group. $L^*$ of meat color, appearance, meat color, marbling score and overall acceptability in sensory score of fresh meat were higher in the pigs fed silage (T) than those fed commercial diet (C). In fatty acid compositions of loin, stearic acid and oleic acid were lower in T than C, whereas arachidonic acid, EFA (essential fatty acid) and EFA/UFA (unsaturated fatty acid) were higher in T.

The objective of this study was to provide basic information for selecting the right timing and the right place of erosion control of stream on Gyeongsangnam-do. In order to achieve this objective, a total of 526 erosion control dams and 230 mountains stream conservation facilities on the constructed places and construction planned places for the erosion control were investigated on site, forest physiognomy, and hydrologic conditions. The erosion control dams and mountain stream conservation facilities were mostly constructed in the area, which has the sedimentary rock, 200-400m of altitude, a slope of 21~30°, and II of landslide hazard map. Among the forest environmental factors, it was only similar to the construction frequency in the areas that have small diameter class, III age class. Also, we investigated the hydrological environmental factors that determine the size and numbers of erosion control dam. The places constructed to the highest frequency were below 50ha in the area, 2.1~4.0km/㎢ of drainage density, longitudinal water system, 61~90mm of maximum precipitation per hour, and 201~300mm of day maximum precipitation. As the results, the sites and floodgate conditions between the constructed places and stream conservation facilities for the erosion control showed to be very similar. Therefore, these results indicate that the erosion control of the stream of the areas, which have the disruption of mountain peaks and the high erosion risk areas, should be used on both the erosion control dam and stream conservation facilities.

Purpose : This study aims to assess the impact of the emotional labor on female dental clinic employees' intention to leave, and the moderating effect of internal marketing, reducing the intention to leave and providing basic data for an effective human resources management of dental clinics. Methods : The structured self-administered questionnaires were distributed to dental hygienists, dental assistants and other employees (including administrative staff and dental coordinators, but excluding dentists) working at a dental hospital and at dental clinics in the Busan and Gyeongnam area. This study used SPSS Windows version 18.0 program (Chicago, IL, USA) to perform frequency factor, reliability, correlation, and hierarchical regression analyses were performed using SPSS. Results : First, emotional labor had a positive effect on the intention to leave. Two components of the internal marketing, communication and employee welfare system, had a significant moderating effect on the relationship between employees' emotional labor and their intention to leave, while the education/training component of the internal marketing showed no moderating effect. Conclusion : Enhancement of communication and the employee welfare system will help dental care organizations reduce their employees' emotional labor and hence employees' turnover.

The purpose of this study was to numerically analyze the heat flow characteristics of an automotive radiator. Heat flow analyses were conducted on the cooling water and outdoor air of the radiator, as well as the temperature distribution of the cooling water after heat transfer. The results of the study revealed that neither heat transfer nor radiator volume was affected by the position of the inlet of cooling water. However, temperature distribution was affected by the position of both the inlet and outlet. In case of heat transfer, three models underwent about 158 kW of heat transfer. The difference in cooling water temperature was about $10^{\circ}C$. In case of pressure drop, the core external air side was reduced to about 1,375 Pa, and the internal cooling water side about 14,570 Pa.
