The aim of this study was to clarify the origins of grubs which were used in the experiments, and to determine many other effects that are now written in the classical medical and herbal books. We compared the efficacy of grubs written in the herbal and medical books on the one hand, and studied the origins of grubs used in the experiments, on the other hand. The following results were obtained. There are three kinds of grub species for medicinal uses. Holorichia diomphalia Bates mainly produced in China, Cetoniidae species mainly produced in Korea, and Protaeria brevitarsis in Korean folk remedy are three species. Grubs were used in 25 experiments. Of these experiments, Holotrichia diomphalia were used 12 times, Larve of Protaeria brevitarsis 3 times, and Protaetia orientalis was used once. So, of total 25 experiments, 36%(9 experiments) did not clarify the origins of grubs used in the experiments. Currently, the grubs, which are imported from China and used in Korea, are Holotrichia diomphalia Bates from China. Current experimental study shows that grubs have efficacy for protecting liver. So the use of grubs in folk medicine is believed to be based on the scientific evidence. Efficacy of grubs, though it is not recorded in the medical books, has the effects of anti-cancer(anti-tumor), antioxidant, and anti-diabetes mellitus. The ingredients of Holotrichia are protein, peptide, fat, enzyme, mineral, and other several nutrients. Study on the grubs so far has a tendency to be done with little focus on the differen of origin of grubs. So, from now on, it needs that the origin of grubs be clarified, and the study on the efficacy from each origin be done. Considering the effects that the classical herbal books have recorded, it is necessary that more profound study proceed to prevent and treat diseases on eyes and ears, on the basis of the fact that grub has multiple ingredients to replenish the vital essence.

1985~1990년에 실내 및 야외에서 큰검정풍뎅이와 참검정풍뎅이의 산란활동을 조사하였다. 실온하에서 큰검정풍뎅이와 참검정풍뎅이의 산란기간은 31.70$\pm$13.33일, 61.17$\pm$23.15일, 실제산란일수는 9.00$\pm$5.03일, 22.33$\pm$11.72일, 자충당 총산란수는 23.43$\pm$16.26립, 65.67$\pm$37.97립, 자충당 1일 산란수는 2.60$\pm$2.50립, 2.94$\pm$2.34립으로 자충당 총산란수의 차이는 주로 산란일수에 기인하는 것으로 보였다. 큰검정풍뎅이에 있어 실온하에서의 산란시기는 야외에서의 산란시기보다 현저히 늦어졌으나, 참검정풍뎅이에 있어서는 실온과 야외에서의 산란시기가 거의 중복되었다. 야외에서 참거정풍뎅이의 장란충율은 큰검정풍뎅이보다 명백히 높았으나 장란충당 장랑수는 두 종이 거의 같았다. 참검정풍뎅이 성충은 망실 내에서 잡초의 초종간에 뚜렷한 산란 및 섭식선호성을 보이지 않았다.

Joint attention, language development, and the relationship between these two variables were compared in infants from multi-cultural and Korean families. Joint attention was observed in both the Early Social Communication Scale (ESCS) and in infant-mother free play. Language development was evaluated by means of the MacArthur-Bates Communicative Development Inventory-Korean. There were no group differences in initiating and responding to joint attention in ESCS. However, in infant-mother free play, joint attention episodes were less and shorter in duration with infants from multi-cultural families than in Korean infants. The size of both the expressive and receptive vocabulary was also smaller in infants from multi-cultural families than in Korean infants. In terms of Korean infants, mean duration of joint attention episodes in free play showed a significant positive correlation with the size of the expressive vocabulary and initiating joint attention in ESCS also showed a significant positive correlation with the size of receptive vocabulary. However, none of the measures of joint attention indicated a significant relationship with the size of either expressive or receptive vocabulary in infants from multi-cultural families.

Since 1990, the National Cancer Institute(NCI) has screened more than 60.000 compounds against a panel of 60 human cancer cell lines. The 50-percent growth-inhibitory concentration (GI$_{50}$) values encode unexpectedly rich, detailed information on mechanisms of drug action and drug resistance. Each compound's pattern is like a fingerprint, essentially unique among the many billions of distinguishable possibilities. These activity patterns are being used in conjunction with molecular structural features of the tested agents to explore the NCI's database of more than 460, 000 compounds, and they are providing insight into potential target molecules and modulators of activity in the 60 cell lines. For example, the information is being used to search for candidate anticancer drugs that are not dependent on intact p53 suppressor gene function for their activity. It remains to be seen how effective this information-intensive strategy will be at generating new clinically active agents.s.

The purpose of this study was to investigate whether young children with cleft palate differ from those of noncleft typically developing children in terms of expressive vocabulary size, phonological characteristics and lexical selectivity. A total of 12 children with cleft palate and 12 noncleft children who were matched by age and gender participated in the study. The groups were compared by size of expressive vocabulary reported on Korean version of MacArthur-Bates Communicative Development Inventories and the number of different words, consonant inventory, the percentage of words beginning with obstruents and vowels, nasal, and glottal sounds, and the percentage of words which do not include obstruents in a language sample. Also, correlation analysis were performed to examine the relationship between measures on size of expressive vocabulary and phonological characteristics. The results showed that expressive vocabulary size and consonant inventory for children with cleft palate produced significantly smaller than those for noncleft children. Children with cleft palate produced significantly more words beginning with vowel or which do not include obstruents, and fewer words beginning with obstruents than noncleft children. The two groups showed different results on significant correlations between measures on size of expressive vocabulary and phonological characteristics indicating that children with cleft palate show different lexical selectivity from their noncleft peers. The results suggest that children with cleft palate aged 18-30 months demonstrate a slower rate of lexical and phonological development compared with their noncleft peers and they develop lexical selectivity reflecting cleft palate speech. The results will have a clinical implication on speech-language intervention for young children with cleft palates.

Ingestion of shellfish-associated Vibrio parahaemolyticus is the primary cause of potentially severe gas-troenteritis in many countries. However, only Kanagawa phenomenon (hemolysin) positive (KP$\^$+/) strains of V. parahaemolyticus are isolated from patients, whereas >99％ of strains isolated from the environment do not produce this hemolysin (i.e. are KP$\^$-/). The reasons for these differences are not known. Following a temperature downshift, Vibrio parahaemolyticus enters the viable but noncultur-able (VBNC) state wherein cells maintain viability but cannot be cultured on routine microbiological media. We speculated that KP$\^$+/ and KP$\^$-/ strains may respond differently to the temperature and salinity conditions of seawater by entering into this state which might account for the low numbers of cul-turable KP$\^$+/ strains isolated from estuarine waters. The response of eleven KP$\^$+/ and KP$\^$-/ strains of V. parahaemolyticus following exposure to a nutrient and temperature downshift in different salinities, similar to conditions encountered in their environment, was examined. The strains included those from which the KP$\^$+/ genes had been selectively removed or added. Our results indicated that the ability to produce hemolysin did not affect entrance into the VBNC state. Further, VBNC cells of both biotypes could be restored to the culturable state following an overnight temperature upshift.

Mekong River is the world's $10^{th}$ longest river and runs through China's Yunnan province, Burma, Thailand, Laos, Cambodia and Vietnam. And Tonle Sap Lake, the largest fresh water body in Southeast Asia and the heart of Mekong River system, covers an area $2,500-3,000Km^2$ in dry season and $10,000-16,000Km^2$ in wet season. As previously noted, the water within Sap river flows from the Mekong River to Tonle Sap Lake in flood season (between June and October) and backward to Mekong River in dry season. Recently the flow regime of Sap River might be significantly affected by the development of large dams in upstream region of Mekong River. This paper aims at basic study about the large scale flood inundation of Cambodia using by CAESAR-Lisflood. CAESAR-Lisflood is a geomorphologic / Landscape evolution model that combines the Lisflood-FP 2d hydrodynamic flow model (Bates et al, 2010) with the CAESAR geomorphic model to simulate flow hydrograph and erosion/deposition in river catchments and reaches over time scales from hours to 1000's of years. This model is based on the simplified full Saint-Venant Equation so that it can simulate the interacted flow of between Mekong River and Tonle Sap Lake especially focusing on the flow direction change of Sap River by season.
