This study was conducted to investigate the effect of fine bubble water treatment on the growth of ginseng seedlings. The growth of ginseng seedlings which were treated with general water and fine bubble water was investigated. The above ground part, the growth of leaf was increased by about 10% and the growth of the stem was about 6%, as the ginseng seedlings which were treated with fine bubble water comparing to the ginseng seedlings treated with general water. Root length was increased about 5%, root width was increased about 8%, roots weight was increased about 9%, and dry weight was increased about 7%. This is not because the whole root growth was increased, but the main root growth was increased about 7%. These results suggested that the physical properties of the fine bubble water stimulated the growth of ginseng seedlings. These results are initial study in the case of ginseng seedlings. Therefore, it can be applicable to the 3-5 years old ginseng plants. Further research will be needed to find out the optimal cultivation condition by controlling the dissolved oxygen amount according to the soil condition and the research applied to the ginseng seedlings.

The purpose of the present study is to clarify the process of change to the pond at the Jongmyo Shrine(宗廟), from the Joseon Dynasty period to the modern and contemporary era. The consequent research results can be summarized as follows. The first record of the Jongmyo pond is confirmed in the "Annals of King Sejong(世宗實錄)". The pond, which was being constructed at the time, refers to the current upper pond(上池). A pair of islets(雙島) were constructed during the Sukjong(肅宗) period, with several trees planted on the middle islet(中池). The middle pond is thick with lotuses. In particular, the middle island on the middle pond subsequently changed into a single island(單島), which is likely to be related to the pond expansion during the reign of Youngjo(英祖). When the lower pond(下池), involving dualistic arrangement, was constructed in the modern and contemporary era, the pond of the Jongmyo Shrine underwent a drastic transformation phase. The lower pond was constructed before 1947 at the latest, and when the right side of the lower pond was filled in the mid 1980s, the dualistically arranged lower pond became a unified type of lower pond. On the other hand, the bank protections of the upper and middle ponds were constructed with earth, but was subsequently modified into its current form using stone.

The purpose of this article is to examine how the 'bodily culture' of older men who gather at Jongmyo Park serves to express and solidify their sense of a enduring self. The research was carried out based on the anthropological methods of participant observation and in-depth interviews at Jongmyo park and its adjacent areas. In later life, the image of a continuous self becomes harder to achieve due to the ageism prevalent in modern societies. The situation is worse at Jongmyo park since the park itself has been stigmatized as "the extraterritorial zone for the old" by the media due to the boisterous atmosphere of the park. It is dubbed as a place for those who have nowhere else to go. The singing and dancing, which used to be the dominant forms of activities at the park among older men until the 'sanctification' project propelled by the government, serves as an antidote against the ageist tendency to subjugate them. The 'bodily culture' embodies these men's image of themselves as a continuous being which has not been tarnished by the passage of time. The approach of 'body hermeneutics' is required to interpret the experiences of the body in later life.

At the Poryoung coast, the spawning season of the mullet, Chelon lauvergnii lasts from May to June. A combination of rotifer, Rotifer nauplii and synthetic feed supported significantly (P < 0.05) better survival and growth of 1-day old mullet larvae during 70-day rearing experiment than the other feeds consisting of rotifer or rotifer + Artemia nauplii. Significantly higher growth and survival were also observed, when the larvae were fed on rotifer, that were harvested from culture enriched with masimaTR, or Artemia nauplii from culture enriched with cuttlefish liver oil, At the feeding density of 97-98 individuals /200 l, the mullet larvae displayed maximum growth and survival in aquarium each with 100 larvae /200 l.

강도다리(Platichthys stellatus)는 분류학적으로 가자미목 강도다리속에 속하는 어류로서 우리나라 북부연안, 일본, 태평양 일대에 광범위하게 분포하며, 산란을 위해 강하류까지 거슬러 올라가는 연안정착성 어류이다. 최근 하천 및 연안의 오염으로 인하여 강도다리의 어획량이 감소하고 있어, 양식기술 개발을 위한 인위적인 어미의 성숙촉진 및 종묘생산에 대한 관심이 높아지고 있다. 그러나 넙치류와는 달리 수컷 어미의 정액량이 적어 종묘생산시 어려움을 겪고 있는 실정이다. 암컷에 비해 수컷의 정액량이 적어 종묘생산이 어려운 어종인 뱀장어(Ohta et al., 1996)와 감성돔(Lau et al., 1996)에서는 호르몬을 투여하여 정액량을 증산시켰다는 보고가 있다.

The purpose of this study is to analyze contents and process of rites about sacrificial rites related Royal Mausoleums in early Joseon Dynasty, and to conclude, to review the position of Royal Mausoleums in the whole National Rites System. The sacrificial rites related Royal Mausoleums started from building Royal Mausoleums of 8 persons-ancestors since King T'aejo's great-great-grandparents, in 1392, founding Joseon Dynasty. In 1408, King T'aejo had died and his Kŏnwŏnnŭng (健元陵) was builted in Yangju, Gyeonggi-do. Since then, after kings of many generations died, each of Royal Mausoleums was builted solemnlly. In the process of this, sacrificial rituals modified and supplemented, especially during the reign of king Sejong(1418~1450). After all, the sacrificial rites related Royal Mausoleums was settled in KukchoOryeūi(國朝五禮儀, Five State Rites) compiled during the reign of King Sŏngjong. In process of Institutionalization of sacrificial rituals, the argument between king and vassals about four-seasons' ancestral rites was properly or not was occurred. That was because the memorial times of Royal Mausoleums overlaped Chongmyo's and more important Chongmyo's ancestral rites was neglected. But four-seasons' ancestral rites of Royal Mausoleums was continued until 17th century. Sacrificial rites related Royal Mausoleums as royal personal rites had simple processes compared to sacrificial rites of Chongmyo, upper-graded formal ancestral rites, under National Rites system. Justifying to served his parents with devotion, the kings in early Joseon Dynasty went to Royal Mausoleums 2-3 times annually. During coming and going, he show off his presence as king in power to his subjects through magnificent guard of honor. On the one hand, he met his subjects directly and acceded to various petition. Above all things, The kings in early Joseon Dynasty emphasized his military power through military training, namely, hunting, disposition of troops, and so on.
