Objectives :The purpose of this study is to investigate the effects of aroma therapy on sleep disorder patients with musculoskeletal pain. Methods :The 44 patients were divided into 2 groups: Experimental group(Exp. group) was treated with aroma therapy and control group was treated except aroma therapy. To evaluate the efficiency of aroma therapy, the Korean sleep scale A(Jin-Joo Oh, Mi-Soon Song, Sin-Mi Kim. 1998) and visual analogue scale(VAS) were applied before treatment and after 5 days treatment. Results :1. The Experimental group has improved statistical significance in sleep disorder score as compare to the control group. 2. The improvement of sleep disorder score of Exp.group has difference according to impression. 3. The improvement of sleep disorder has an effect on pain decrease. Conclusions :Aroma therapy has effects of improvement on sleep disorder with musculoskeletal pain.

본 연구의 목적은 김만덕이 성공한 CEO로서 보여준 기업가정신을 체계적으로 살펴보고, 그녀가 지녔던 기업가정신이 우리에게 주는 시사점을 도출하는데 있다. 논문은 크게 두 부분으로 구성되어 있다. 첫 번째는 김만덕의 생애와 김만덕이 CEO로 역할을 수행했던 당시의 시대적 배경을 살펴보았다. 두 번째는 김만덕이 보여준 기업가정신을 분석하여 시사점을 도출하고자 하였다. 이를 위하여 먼저 기업가정신의 일반적인 내용을 살펴본 후, 조선시대 최초 여성 CEO 김만덕의 기업가정신을 분석하여 시사점을 찾고자 하였다. 김만덕이 보여준 기업가정신을 파악하기 위하여 개인 차원에서 기업가정신을 연구한 Chrisman et al.(1998)이 제시한 특성 중에서 창업 경험을 제외하고 인성적 특성, 가치 및 신념, 능력, 행동적 특성 등 4가지 관점에서 김만덕이 보여준 기업가정신을 분석하였다. 김만덕에 관한 대부분의 기록과 작품들은 김만덕의 삶과 행적을 긍정적으로 묘사하고 있다. 따라서 김만덕의 삶을 객관적으로 조명하는 가운데 김만덕이 보여준 기업가로서 의 정신적 가치를 발굴하고 현대적 관점에서 재평가하는 작업은 필요하다. 다만 제한된 지면의 사료나 자료에 의존하여 이루어진 평가이기 때문에 주의가 필요하다고 생각된다. The purpose of this paper was to identify the entrepreneurship of Kim Man Deok. This paper was divided into two parts : first is the Kim Man Deok s life stages and characteristic of the age, second is the entrepreneurship of Kim Man Deok. Kim Man Deok‘s life was divided into three time periods : fight against fate, as a CEO, donating her possession to society.

Hydrogen for the Future Green Energy
( Ha Suck Kim ),( Sung Yul Bong ),( Seung Hee Woo ) 경남대학교 신소재연구소 2012 신소재연구 Vol.24 No.-
Many agree that the future energy will be hydrogen after the recent energy crisis which brought us to reconsider seriously about possible alternatives after fossil fuel for mankind. There are abundant sources for hydrogen-water, and it burns to form water. However, in order for us to adopt the new energy system, many hurdles have to be overcome. They are how to produce hydrogen economically, ways to store and transport safely, and ways to generate electricity efficiently, to name a few. Electrochemical generation of hydrogen needs a high overvoltage, thus, it is a very expensive way at the moment. Also, storage and transport require many fundamental researches. Efficient use of hydrogen is fuel cell. Fuel cells have been received a considerable interest as power sources because they exhibit high energy efficiency and are environmentally friendly. Despite these advantages, fuel cells in general need to overcome economic barriers for wide applications. Main barriers are the cost of materials such as platinum used in catalysts and proton conducting polymer. Catalysts are the core material for fuel cell and many attempts have been made to find out the most active, efficient and durable formulae in the MEA preparation step.[1-2] In this respect, works performed in our group for fuel cell catalysts will be summarized, they are preparation of by galvanostatic pulse electrodeposition on Nafion-bonded carbon layer [3-5], and effect of carbon supports for catalysts. Improved catalytic performance by choosing appropriate flow channels in the support was also observed. Also in this presentation, energy statistics and efficient way of use energy, possible future energy scheme will be discussed. [1] Hubert A. Gasteiger, Shyam S. Kocha, Bhaskar Sompalli, Frederick T.

Backgrounds/Aims: Historically, incidence and survival analysis and annual traits for primary liver cancer (LC) has not been investigated in a population-based study in Korea. The purpose of the current study is to determine incidence, survival rate of patients with primary LC in Korea. Methods: We conducted a retrospective cohort study using Korea Central Cancer Registry based on the Korea National Cancer Incidence Database. Statistical analysis including crude rate and age-standadized rate (ASR) of incidence and mortality was performed for LC patients registered with C22 code in International Classification of Diseases, tenth revision from 1999 to 2019. Subgroup analysis was performed for hepatocellular carcinoma (HCC, C22.0) and intrahepatic cholangiocarcinoma (IHCC, C22.1). Results: The crude incidence rate of HCC (21.0 to 22.8 per 100,000) and IHCC (2.3 to 5.6 per 100,000) increased in the observed period from 1999 to 2019. The ASR decreased in HCC (20.7 to 11.9 per 100,000) but remained unchanged in IHCC (2.4 to 2.7 per 100,000). The proportion of HCC patients diagnosed in early stages (localized or regional Surveillance, Epidemiology, and End Results or SEER stage) increased significantly over time. As expected, 5-yeat survival rate of HCC was greatly improved, reaching 42.4% in the period between 2013 and 2019. This trait was more prominent in localized SEER stage. On the other hand, the proportion of IHCC patients diagnosed in localized stage remained unchanged (22.9% between 2013 and 2019), although ASR and 5-year survival rate showed minor improvements. Conclusions: A great improvement in survival rate was observed in patients with newly diagnosed HCCs. It was estimated to be due to an increase in early detection rate. On the contrary, detection rate of an early IHCC was stagnant with a minor improvement in prognosis.

The purpose of this study was to determine the effect of cows parity and calving seasons on the subsequent reproductive performance of the herd of Korean native cows raised under the same condition. With the parity of the cows ranged 1 to 4 (mean: 1.9), significant associations were found between parity and calving interval (p<0.05). Calving interval of the primiparous cows group was 395.0 16.5 days, which was the longest calving interval among the four groups. On the other hand, calving interval of the second parity group was 333.7 3.6 days. The primiparous cows had tendencies that long interval from calving to conception and small number of service per conception relatively when compared with the multiparous cows. In the case of calving season, the interval from calving to first service was short in summer and winter relatively. The interval from calving to conception in summer was the shortest in four seasons. The number of service per conception was larger in spring and winter and smaller in summer and autumn. Calving in spring showed delayed reproductive performance and calving in summer showed desirable reproductive performance.

Purpose: Using agricultural machinery was not easy in the conventional shading structure, specified as a standard facility by standard cultivation methods for ginseng. Thus, this study designed the new types of facility allowing machine access by modifying the conventional type. Methods: Two types of facility (i.e. wide roof type and long & short roof type) were designed and installed in an experimental site to evaluate its growing environments and applicability of riding-type cultivator. Results: From the results of incoming light measurement, all three types (i.e. two new types and a conventional type) of shading structures blocked the incoming light after 9:00 am. The temperature distribution inside the new types was similar with the one in the conventional type, so the growth of ginseng was in good condition in all three types of facility. The riding-type cultivator was operated well with the low speed first gear of 0.13 m/s in the new types. However, a long & short typed roof needs to be raised 18 cm height in order to use the cultivator. Conclusions: With the results of this study, the new types of roof can be used in the ginseng farm in that they satisfied the growing environments for ginseng and the needs for agricultural mechanization.
