  • 선진 전력시장에서는 전력산업의 환경이 수용가 중심의 시장구조로 변화함에 따라, 이들을 대상으로하여 IT 기반의 다양한 전력부가서비스가 제공되고 있다. 이러한 서비스에 대한 연구개발은, 시간이 흐르면서 단방향이 아닌 양방향 통신 기반의 소비자 중심 서비스 분야로 확대되는 경향을 보인다. 특히, 미국 EPRI의 IntelliGrid 컨소시엄에서 제시한 수용가 포탈은 소비자 영역내의 장비와 에너지 서비스 기관 간의 양방향 통신을 지원하는 통합적인 개념의 서비스 기반으로, ESP(Energy Service Provider)와 소비자는 더욱 상세한 정보를 이용하여 더 많은 이익과 혜택을 기대할 수 있다. 이에 비해 국내의 전력부가서비스 제공 수준은 아직 시작 단계에 불과하지만, 머지않아 국내 전력시장 역시 양방향 통신 기반의 수준 높은 전력부가서비스를 요구하게 될 것으로 보인다. 따라서 국내환경에 적합한 수용가 포탈 기반의 전력부가서비스 개발이 필요하며 이를 통해 수용가에게는 비용 절감이 가능한 합리적인 소비 방안을 제시하고, ESP에게는 부하 수요관리 및 투자비를 절감할 수 있는 기회를 제공해야 할 것이다. 본 논문에서는 새로운 전력부가서비스를 기반이 될 수용가 포탈을 분석하고, 현행 전력부가서비스의 현황과 동향 분석, 적용가능 기술 분석을 수행하여 그 결과를 바탕으로 국내환경에 적합한 수용가 포탈시스템 기반의 전력부가서비스 선정 및 구축 방안을 제시하고자 한다.

  • A study was conducted to provide direct comparisons of the effect of variations in herbage use, grazing and social behaviour upon the flat, slope and forest grassland with a total 30 Korean Native Cattle and 5 Korean Native Goats under 4-year old grassland established by intensive sowing method in Daecheon. The results obtained are summarized as follows; 1. Relative intake index, dry matter intake per animal and dry matter digestibility by Korean Native Goats in flat, slope and forest grassland were 35.2%-462g-63.7%, 35.0%-459g-63.0% and 29.8%-391g-62.1%, respectively. 2. Grazing time by Korean Native Cattle was not different among the grassland types, but ruminating time was increased in slope grassland, whereas in forest grassland was decreased. Resting time was increased in forest grassland, whereas in slope grassland was decreased. Walking time was increased in flat grassland, but loafing time was increased in forest grassland. The number of rumination, chews per bolus and defecation number were decreased in forest grassland. The number of drinks, total drinking water and walking distance were increased in slope grassland. 3. Animal distance, occupied area per animal and sub group formation by Korean Native Cattle in flat, slope and forest grassland were $3.4m-11.9m^2-3.6head$, $3.56m-11.0m^2-3.7head$ and $3.70m-14.6m^2-3.4head$, respectively. The order of grazing movement was similar to the pear-shaped grazing formation, but the relations of dominance between first grazer and last grazer upon different grassland types was not clear.

  • A survey was conducted for 221 male and 191 female college students to study correlations between dietary food intakes and body composition. Among the subjects 75 male and 82 female students were analyzed body protein mass, body mineral mass, percent body fat, waist-hip ratio (WHR), body mass index (BMI) and fitness score using Inbody 3.0. The results show that 94.6% of the males and 24.7% of the females were observed at high level in body protein mass. As for body mineral mass, 86.4% of the males were observed below the normal range. As for WHR, 32.1% of the males and 43.5% of the females were evaluated as abdominal obesity. As for BMI, 34.8% of the males were observed above the normal range. In female students, correlation coefficient between sodium intakes and age showed significantly negative 0.232 while correlation between calcium intakes and self-reported health status showed significantly positive 0.234. In males, correlation coefficient between fiber intakes and self-reported health status resulted in significantly positive 0.237 and that between BMI and age showed significantly positive 0.276. In females, correlation coefficient between type of living and WHR showed significantly positive 0.253 and that between self-reported health status and percent body fat showed significantly positive 0.230. Also correlation coefficient between body protein mass and sodium intakes showed significantly negative 0.276 in female students.

  • Manjungpan Chunhyangga is established by Manjung Kim Sohee. She selectively chose and arranged the songs by Jung Jungryeol, Song Mangap, Jung Eungmin, Kim Yeonsoo, Park Dongsil, and Jung Kwangsil. Kim Sohee once stated that while a major section of Chunhyangga is based on the songs by Jung Jungryeol, Song Mangap, Jung Eungmin, and Kim Yeonsoo, the whole part of Okjungga is derived from Park Dongsil. However, there is not much material that will provide enough information with regard to what musical characteristics Park Dongsilje Chunhyangga possessed. Under the circumstances, the voice of Park Dongsilje, left by Kim Sohee, triggers curiosity on Park Dongsilje Chunhyangga. It can also be construed that there must be a good reason for choosing Park Dongsilje for Okjungga, unlike other parts. Therefore, this paper attempted to find out what the unique features of Par Dongsilje are and what the reasons behind Kim Sohee's musical choice were through comparison and analysis of Kim Sohee's musical features in Okjungga. The following are the results. Firstly, Okjungga is a created verse by its nature and it does not possess specific features to a school. Therefore, the reason for choosing Park Dongsilje could have been based on musical reason rather than verse. Secondly, the lyrics of Park Dongsilje Okjungga is closer to that of Song Mangap rather than that of Jung Jungryeolje. It can be argued that it falls between the two of them. Thirdly, the tone and melody of Park Dongsilje Okjungga falls in the middle section of Dongpyenje and Supyenje. Fourthly, the analysis of Jinyangjo rhythm out of the whole Manjungpan Chunhyangga shows that there are slight differences among Song Mangapje, Jung Jungryeolje, and Jung Eungminje. Park Dongsilje is very unique in the sense that it does not use utbutim in gyemyeonjo part in Manjungpan Chunhyangga. Park Dongsilje Okjungga is a song to which the tone, melody, and sigimsae of Supyeonje is added to lyric butimsae of Dongpyeonje. It can be seemed as simple and less sophisticated because, with its simple lyric butimsae, it shows a less complicated tone utilization rather than Jung Jungryeol. With lighter decoration of music, feelings can be conveyed more directly. That is probably why Kim Sohee commented on Park Dongsilje Chunhyangga that it is the most mournful song for Chunhyang and it is the song that moves anyone who listens to the song. Consequently, Kim Sohee accepted Park Dongsilje Okjungga and she created different feelings to Manjungpan Chunhyangga which has repeatedly displayed the color of Jung Jungryeol. Combining the lyric addition of Dongpyeon style and the melody of Supyeon style can crated a different language.

  • To evaluate orthostatic brain hypoxia from the passive tilt, anesthetized dogs were tilted from supine to $90^{\circ}C$ upright and $90^{\circ}C$ head down position. Blood pH, $Pco_2$ and $Po_2$ changes during tilt were measured on 8 dogs. Respiratory rate was decreased in upright position and increased in head down position comparing to that in rte horizontal position. pH in arterial blood was increased in upright position and decreased in venous blood comparing to that in the horizontal position. No significant changes were found in the head down position. $Pco_2$ of arterial and venous blood was decreased both in upright and head down. position A significant decrease was found in the head down position. $Po_2$ in arterial blood was increased both in the upright and head down position. However, it was decreased in the venous blood. The cause of increased $Po_2$ in arterial blood seemed to do due to hyperventilation and the cause of decreased $Po_2$ in venous blood was thought to be due to increased $O_2$ consumption of animals during the tilt.

  • This study was performed by questionnaire to investigate the recognition and prospect for Korean traditional Pyebaeck Foods. The subjects of this study consisted of 621 housewives in Daegu area. The results were summarized as follows: The most people(94.2%) had ever seen Pyebaeck refreshments before, and most had seen them in wedding halls(62.5%). The reason they do prepare Paebaek refreshments was “it's tradition”(44.9%), and they considered this tradition as a public moral. The peoples who had prepared Pyebaeck refreshments at home consisted 51.0% and those who had purchased at caterer was 59.5%. The reason for preparing the refreshments at home was usually “it's true-hearted”(48.8%) and the reason for hiring specialists was “it's more convenient”(38.7%). Opinions about cooking method were mostly “complicated”(79.8%), and the knowledge score for cooking methods was low in 2.80. 31.3% of respondents reported inheriting their recipes from their mother. 43.3% of the respondents thought it would be “transmitted only a part” on prospects for Pyebaeck refreshments. 31.5% of the respondents said the improvement plan should be “focused on development of various Pyebaeck refreshments with modern senses” and 30.4% that the industralization should be effected through “publicity activities and education about its excellence”. People had to experience the Pyebaeck in the right way and to understand its real meaning better in order not to consider it as an evil custom, empty formality and vanity.

  • The purpose of this study is to examine the effects of personal characteristics and social entrepreneurship on social entrepreneurship intention, and to determine whether the moderating effect of gender influences on the relationship between personal characteristics and social entrepreneurship. In order to achieve these research objectives, the personal characteristics affecting social entrepreneurship were identified with moral obligation, self-efficacy, and emotional intelligence. Also, prior studies on social entrepreneurship and social enterprise entrepreneurship intention were reviewed. As a result of the study, we find that moral obligation, self-efficacy, and emotional intelligence all had a positive effect on social entrepreneurship. Second, social entrepreneurship had a positive effect on social enterprise entrepreneurship intentions. Third, analyzing the moderating effect of men and women in the relationship between personal characteristics and social entrepreneurship, it was found that there was a difference in the value of the path coefficient representing the relationship between moral obligation and social entrepreneurship. However, there was no moderating effect in the relationship between self-efficacy, emotional intelligence, and social entrepreneurship by gender. Therefore, this study is expected to serve as a reference for people who want to start a social enterprise in the future to verify their characteristics and use them as a way to improve their social entrepreneurship.

  • This study aimed to derive theoretical and practical implications by analyzing the relationship between adversity quotient, entrepreneurial orientation, and customer orientation, which are the internal competency of start-up entrepreneurs affecting the performance of a small business CEO. As in previous domestic studies, we deviated from analyzing internal competency as a single-dimensional functional relationship to business performance, and attempted to explain the relationship between the internal competences of start-up entrepreneurs. Empirical analysis was conducted by setting the adversity quotient as an independent variable, the entrepreneurial orientation as a parameter, and the customer orientation as a dependent variable. As a result of the analysis, first, it was found that control and ownership, which are sub-elements of adversity quotient, have a positive effect on entrepreneurial orientation and customer orientation. Second, entrepreneurial orientation was found to have a positive effect on customer orientation. Third, it was found that only the ownership of the adversity quotient had a positive effect on customer orientation through the mediating effect of entrepreneurial orientation. In other words, it was found that the entrepreneur's ownership influences customer orientation through entrepreneurial orientation. On the other hand, endurance, sub-element of adversity quotient, was found to have no significant effect on entrepreneurial orientation and customer orientation. This means that in the rapidly changing New Normal era, endurance of entrepreneur can no longer have a large impact on entrepreneurial orientation and customer orientation. This study gives implications for the entrepreneur's competencies that must be developed first and the tendency to be developed together. Furthermore, it can be helpful in policy designing start-up support programs and guidelines for investors' investment standards.

  • The hexavalent chromium (Cr(VI)) is well known as a hazardous ion, presumably inducing dermatic diseases and if serious cancer. The present study concerns the binding capacity of Cr(VI) ions in the cement powder and matrix for a quantitative technique of Cr(VI) ions in cement to influence human health. Both the water-soluble and acid-soluble Cr(VI) ions present in 3 types of ordinary Portland cement (OPC), pulverised fuel ash (PFA), ground granulated blast furnace slag (GGBS), and silica fume (SF) were measured using the spectrophotometer. As a result, it was found that the concentration of water-soluble Cr(VI) ion in cement ranged from 10.5 to 18.9mg/kg-cement, and in the additional materials a very low value of Cr(VI) ion was measured. Acid-soluble Cr(VI) ion was even higher than water-soluble Cr(VI) ion, ranging from 172.4 to 318.2mg/kg-cement. Nevertheless, the concentration of acid-soluble Cr(VI) ion is not proportional to addition of acid. It depends rather the variable pH of solvent involving cement paste. As enough cement hydration occurs, the binding capacity of Cr(VI) ion increases, inhibiting this ions from leaching out in the presence of hydration products such as ettringite or tri-calcium aluminate which bind Cr(VI) ion by ion-exchange.

  • The mugilidae fishes are common euryhaline species that live in coastal marine waters to freshwater areas. The taxonomy and nomenclature of the mugilidae fishes still remain unresolved because of their morphological similarities. Among the mugilidae fishes, most commonly consumed in Korea, are grey mullet (Mugil cephalus) and red lip mullet (Chelon haematocheilus). It is generally called 'mullet' without distinguishing between two mullets. Therefore, the aim of this study is to examine the scientific names and common names of mullet species used in Korea from the domestic journals and Korean old documents. The scientific name of grey mullet is M. cephalus, but that of redlip mullet is C. haematocheilus. But the genus of redlip mullet is still mixed with Chelon, Mugil, and Liza. The standard name of two mullet is not distinguished in the Korean dictionary, but they were clearly distinguished in the Japanese, English, and Chinese dictionaries. In the ancient Korean references, the mullet was called 'Chieo' or 'Sueo'. In most of the old literature, the distinction between grey mullet and redlip mullet is not clear. However, in Jasaneobo, it was written separately from grey mullet and redlip mullet, and attaching "ga" was different from now. The Korean standard name of redlip mullet is 'gasungeo', however, the fishermen in Jeollado and Gyoungsangdo call it 'chamsungeo'. Considering the negative perception of 'ga' character, it is proposed to change 'cham(眞)' instead of 'ga(假)' to improve economic value of red lip mullet.
