This study aims to prove the relationship between a TPB(theory of planned behavior) variables (subjective norms, attitudes, and self-efficacy), need to belong and personal growth initiatives to explain the reasons for users' shared behavior. 959 participants who had shared online video were collected as a sample through an online survey and the collected data were analyzed through structural equation modeling. The study found that need to belong affected attitudes to online video sharing and subjective norms, and that personal growth initiative also affected attitudes to online video sharing and self-efficacy. In addition, all three variables of TPB were affect the intend of online video sharing, and attitudes to online video sharing were affecting subjective norms and self-efficacy. This study is meaningful in that it demonstrated the user's intention to share online video through variables of TPB along with their need to belong and personal growth initiatives.

Summarizing the past and recent data on pre-Cambrian System in Eastern Asia, it can be concluded that the pre-Cambrian System are composed of the sediments of having four cycles of sedimentation. It is also known that most of pre-Cambrian Systems known so far belong to either one of transgression facies or regression facies in the four sedimentation cycles. The pre-Cambrian Systems can be divided into four stages, that is, Sinian, Hutoan, Liahoan, and Taishanian stage. It is supposed that all pre-Cambrian Systems in Korea will belong to one of these four cycle sedimentations. Therefore, the reasonable way of study of Korean pre-Cambrian Systems is to investigate which stage they belong to.

The results from the consideration of this are as follows. A Study on the Dancer and Musician Costumes by the Murals in Tombs decorate with mural, which is of Liao Dynasty. The tombs belong to two families: eight of them located to the northeast of Xiabali Village belong to the Zhang Family. Another was located to the north of Xiabali Village belong to the Han Family. The bands of the "Sanyue" consist of five to twelve players wearing luxurious dresses(Jamhwasik hwagakBokdu, Danryung, Belt, Boots) and playing miscellaneous musical instruments: sometimes the female ones in the bands are disguised as male. Usually, each band is accompanied with one or a couple of dancers. which one wearing is luxurious dresses (Goge.1amhwasik. Yoo : Jaket : joegori, Sang: skirts: chima, and shoes).

This study was designed to investigate the malnutrition rate with anthropometric indices for the nutrient intake of 74 children aged 4-12 years old in three child welfare institutions in Cheonan city. The average heights and weights of the children are much lower than the Korean average height and weight. The mean BMI is $17.0{\pm}1.53$. In terms of height-for-age, 16.0% of the samples belong to below -2 standard deviation from the mean of the reference group. In terms of weight-for-age, 16.0% of the children belong to below -2 standard deviation. In terms of weight-for-height, 4.0% of the children belong to below -2 standard deviation. The standard deviation scores(Wt/Age, Ht/Age) indicate negative signs for seventy to eighty percent of the children. This is due to the lower consumption of the important nutrients that children consumed and almost all nutrients much less than the recommended daily allowances. Special nutrition welfare policies and programs targcting child welfare institutions should be developed to provide adequate nutrition for children in residential care.

Let G be a simple graph and let G denote its complement. We say that $\bar{G}$ is integral if its spectrum consists of integral values. In this work we establish a characterization of integral graphs which belong to the class $\bar{{\alpha}K_{a,a}\cup{\beta}K_{b,b}}$, where mG denotes the m-fold union of the graph G.

Eight species of Chironomidae (Diptera) which are new to Korea are described with illustrations. They are extremely rare species in Korea, as only one or two specimens have been collected since 1977 throughout the country. Microchironomus tener, Stictochironomus akizukii and Paratendipes nubilus belong to subfamily Chironominae, and the other five species: Diplocladius cultriger, Limnophyes minimus, Metriocnemus fulvofasciatus and Parametriocnemus stylatus belong to subfamily Orthocladiinae.

Previous studies on the host plant range of Metcalfa pruinosa were conducted without distinguishing between its stages of development. In this study, we investigated host plants by studying the nymph and adult development stages of M. pruinosa. M. pruinosa nymphs were found on host plants that belong to 78 families and 227 species, and, to the best of our knowledge, host plants that belong to 27 families and 38 species have been reported for the first time. The host plants were divided into woody and herbaceous at the nymph stage of M. pruinosa, and the nymphs were found in 110 herbaceous and 117 woody species. M. pruinosa adults were found on host plants that belong to 87 families and 233 species, and, host plants that belong to 26 families and 36 species have been reported for the first time. The host plants were divided into woody and herbaceous at the adult stage of M. pruinosa, and the adults were found in 105 herbaceous and 128 woody species. Therefore, the total domestic host plant of M. pruinosa was 98 families 345 species. The nymph and adult in preoviposition stage prefer Helianthus annuus and the adult in oviposition stage prefer Persicaria tinctoria and Rosa rugosa.

For the zoning of natural ecosystem, Vegetation Index is calculated from the vegetation data surveyed on Baekdudaegan (from Namdeogyusan to Sosagogae). Five factors-biodiversity, conservation value of the stand, environmental quality, longevity of the stand, site productivity- are considered in the calculation of Vegetation Index. Vegetation Index might be a useful zoning tool for management of Baekdudaegan. For Vegetation Index I, 8 sample plots 12.l％ of total 66 sample plots are belong to core area, 21 sample plots 31.8％ and 37 sample plots 56.l％ are belong to buffer zone and transition area, respectively. For Vegetation Index II, 37 sample plots 41.9% of total 60 sample plots are belong to core area, 19 sample plots 28.8％ and 19 sample plots 28.8% are belong to buffer zone and transition area, respectively.

Lee and author (2000) rearanged the list of mushrooms recorded in Korea, containing 1,554 species 388 genera from 90 families for the systematic classification of Korean mushrooms at Korea Forest Research Institute. In September, 2002, Lee, Tai-Soo and Kab-Hee Yoon made public ‘The Index of Korea-Japan Mushroom names in Korea’ that listed 1,610 species from 396 genera, 90 families and 23 orders of mushrooms recorded in Korea. Among the listed taxa, 1,369 species, 297 genera, 65 families, 15 orders belong to Basidiomycotina and 241 species, 99 genera, 25 families and 8 orders belong to Ascomycotina. A total of 56 species were newly added to the list of recorded Korean mushrooms for a period of 2 years. On the other hand, a total of 75 species, 3 varieties and 2 formae were added to the list of recorded Korean mushrooms by the author, and they were published by many researchers from 2001 to 2004. Among the published taxa, one forma, 20 species, 16 genera, 12 families belong to Ascomycotina and one forma, 3 varieties, 55 species, 33 genera, 17 families belong to Basidiomycotina.
