This study was to examine the analysis level of implementation of the Nuri Curriculum of age 3 ~ 4 child-care teachers. It recognized general tendencies about the perception and satisfaction and the relation among level of implementation and perception, satisfaction of the Nuri Curriculum of age 3~4 Child-care teachers. And it also recognized the effect of level of implementation on perception and satisfaction. A survey was therefore administered to 264 child care teachers in Seoul and Gyoung-gi do. The collected data were by mean, standard deviation for recognize general tendency about perception and satisfaction, other data were by pearson relation, multiple regression analysis. Results were as follows: Firstly, general perception on Nuri Curriculum of age 3~4 Child-care teachers were a little above average, and there were positive relationships between perception and teachers' the level of implementation. Specially perception of practice and support had a significant positive correlation with theoretical basis and character. Secondly, general tendency of satisfaction were above average, and there were positive relationships between Satisfaction and teachers' the level of implementation. Specially satisfaction of curriculum had a significant positive correlation with assessment and practice and support had a significant positive correlation with teaching material. Thirdly, the practice and support perception exerted the largest influence on the teachers' the level of implementation, and satisfaction of curriculum exerted influence on the teachers' evaluation of the level of implementation.
Process of resuspension and accumulation well explaines the characteristics of surface sediment size distribution and suspended material in Deukryang Bay. Most of the surface sediments of the bay show asymmetric unimodal size distribution, which is found also in sediments from western part of the inner shelf mud area between Keomundo and Yokchido islands. Investigation of the size curves indicates that surface sediment in Deukryang Bay is a deposit of suspended coastal sediment transported east along southern coast of Korea. The distribution pattern of coarse sit fraction content in the surface sediment is very similar to that of computed current velocity (Lee, 1994), suggesting that fine sediment on the bed may reassumed and accumulate repeatedly due to shallow depth and strong tidal current in Deukryang Bay. The process of repeated resuspension and accumulate repeatedly due to shallow depth and strong tidal current in Deukryang Bay. The process of repeated resuspension and accumulation seems to be responsible not only to the asymmetric size distribution of the surface sediment, but also to the amount of suspended material in the bay. The difference of suspended material concentration between surface and near bottom water in summer is two times as large as that the in winter. This seems to derive from the fact that stratification of water mass prevails in summer, while total water mass is vertically mixed in winter. It was found that the most important factors to decide distribution of suspended material in Deukryang Bay are the physical properties of water mass such as current velocity and stratification, and water depth, in part with the supply of suspended sediment by rivers.
The distribution of stock density and larvae of Atrina pectinata was examined in Deukryang Bay. Sampling of adult stock was seasonally conducted from 29 stations in the bay in May, August, and November 1995 and February 1996. And the larvae were sampled with interval of 3 to 7 days from 12 stations from July to October 1996. Seasonal abundance of the adult in number and in biomass were the highest in August ($18\;inds./m^2$) and in November ($2,790\;g/m^2$), respectively, at G1 station located in the most inner bay. In frequency distribution of shell height, the mode in May appeared in 10-14 cm group with 62%, and that of the other seasons in $15{\sim}19\;cm$ group. The larvae were also distributed mainly at G1 as the adult were. The larval abundance showed a periodical cycle which seemed to be related to lunar cycle. The highest abundance of the larvae occurred on August 16 with $8\;inds./m^3$, and then decreased continuously. With regard to frequency distribution of larval shell height, the larvae less than $200\;{\mu}m$ occurred from July to October. And the mode in July appeared in small size group ($200{\sim}249\;{\mu}m$) with 38%. These results mean that A. pectinata spawned from July to October, mainly middle July to middle August. The larval distribution showed the same geographical tendency to adult distribution. Both the adult and the larvae mainly distributed in the most inner bay and west area of Deukryang island, where was shallower, warmer, and higher primary productivity than the entrance area of the bay and east area of the island. However, larval abundance of A. pectinata in this study was so low compared to adult biomass. The reason for this unusual phenomenon should be understood with the detail research in future.

This study was conducted to investigate the macrobenthic community in Ulsan Bay and Onsan Bay, in November of 1997. The density of benthic animals was 535 md./m2, and the number of species was 117. Polychaeta was the most dominant faunal group, comprising a total of 63 species, and its density was 380 md./m2 The most dominant benthic macrofauna was Cirratulrus cirratulas (2.7%), and followed by Tharyx sp. (16.6%), Ruditapes philippinarum (16.1%), Lumbrineris longifolia (10.3%) and so on. The dominant species occupied their distinct unique distribution area. Tharyx sp., R. philippinarum and Grandidierella sp.1 occurred mainly in Ulsan Bay, L. longifolia and Euchone sp. in Onsan Bay, and C. cirratulas and Cirriforimia tentaculata in both bays. By cluster analysis, study area was divided into 4 station groups: Northern Ulsan Bay (Al), the middle area of Ulsan Bay (Bl), offsea area between Ulsan Bay and Onsan Bay (Bll), and Onsan Bay (C). Northern Ulsan Bay was characterized by low species number and high density. The dominant species were C. cirratulas R. philippinarum and Tharyx sp. The middle area of Ulsan Bay was by low species number and density, and its characteristic species was Grandidierella sp.1. The offsea area between Ulsan and Onsan Bay was by high species number and low density. Onsan Bay was by high species number and high density, and its important species were L. longifolia and Euchone sp.

The descendants of Jang, Chang-woo(張昌雨) reconstructed the Mangwijung (晩歸亭), which is currently located at Seha-dong, Seo-gu, Gangju Metropolitan City, in the context of succeeding the work of their ancestor. This study investigated the management viewpoint of Mangwijung that has been altered in going through the reconstruction and repairs processes, and examined the chronological history for a landscape of the Mangwijung Garden. First, in the Mangwijung Garden, three gazebos such as Mangwijung, Seubhyanggag(襲香閣) and Mukamjeongsa(墨庵精舍) stand in a row with three bridges between each of them in the middle of a wide pond. This is a group of gazebos that is a quite unique structure. Second, Hyowoodang(孝友堂) Jang, Chang-woo (張昌雨) built Mangwijung as a role of thatched cottage in order to teach younger students and enjoy the arts in his later life. The Mangwijung was reconstructed by the descendants of Jang, Chang-woo at the collapsed place later on in order to commemorate the achievements of their ancestor. By the way, it was revealed that the management of Mangwijung has been altered during the process of reconstruction. Third, when comparing the current appearance with those depicted in the 8 scenic views(八景) by Jang, Chang-woo and the literary works of his descendants, it was confirmed that the landscape and shape of the pond were damaged due to a road expansion caused by a construction of Seubhyanggag and Mukamjeongsa as well as an advancement of the city. Fourth, it is speculated that the pond of Mangwijung Garden is probably a spring not a reservoir to store the water stream that flows in.
This study has an objective of suggesting the ways to improve infant's sense of self-respect and peer competence, by examining what effect infant temperament has on infant's sense of self-respect and peer competence. The notable study results through analysis are as follows; First, it was shown that, in regard with adaptability and activity of infant temperament, cognitive ability of the sense of self-respect and peer acceptance, the average score of day care centers was higher, while it was shown that, in regard with response of infant temperament, the sense of self-respect's mother acceptance, peer relationship, sociability of peer competence, the average score of kindergartens was higher, and the boy infants' physiological regularity was shown to be higher than that of girl infants. Second, as a result of looking into the difference of infant temperament, sense of self-respect, and peer competence according to infant's age, we found that, in case of 'response' of infant temperament, age 5 group was classified into 'group a', and age 3 and 4 group was classified into 'group b', and two groups showed the difference, and in case of 'physiological regularity', age 3 group had the biggest regularity while age 5 group had the relatively low regularity, thus two groups showed the difference. In regard with sense of self-respect and peer competence, it was shown that age 4 and 5 group had higher one than that of age 3 group.
In this paper, we propose the development of high resolution $360^{\circ}$ omnidirectional IP camera with 12 million pixels. The proposed 12-megapixel high-resolution $360^{\circ}$ omnidirectional IP camera consists of a lens unit with $360^{\circ}$ omnidirectional viewing angle and a 12-megapixel high-resolution IP camera unit. The lens section of $360^{\circ}$ omnidirectional viewing angle adopts the isochronous lens design method and the catadioptric facet production method to obtain the image without peripheral distortion which is inevitably generated in the fisheye lens. The 12 megapixel high-resolution IP camera unit consists of a CMOS sensor & ISP unit, a DSP unit, and an I / O unit, and converts the image input to the camera into a digital image to perform image distortion correction, image correction and image compression And then transmits it to the NVR (Network Video Recorder). In order to evaluate the performance of the proposed 12-megapixel high-resolution $360^{\circ}$ omnidirectional IP camera, 12.3 million pixel image efficiency, $360^{\circ}$ omnidirectional lens angle of view, and electromagnetic certification standard were measured.
Any significant inflow of fresh water due to flood or snow melting can rapidly reduce salinity at the bay. In such a case, the habitat environment in the sea near river mouth can be partly destroyed. Therefore, research to understand the salinity distribution quantitatively at the bay for the utilization of natural environment and for the inhabitant conservation must be very important. In this study, the investigation on the relationship between satellite image and turbidity is carried out first, and then the salinity distribution at the bay using the relationship between turbidity and salinity is derived. The main results are as follows. First the reappearance ability of RGB bands respectively of the satellite image is investigated, and then it was confirmed that the combination of band2 and band3 expressed best the movement characteristics of turbid water at the bay is chopped up into 4 small areas. Second the turbidity of river mouth is estimated using the travel time from the upward monitoring station to the river mouth. Finally the satellite image is converted into the salinity distribution by the correlation of salinity and turbidity. It is confirmed that the salinity distributions obtained from above three investigation methods are quite reasonable and clear.

This paper presents the evidence on the considerably strong stratification - destratification(SD) phenomena during spring - neap tidal cycle in summer of 1992 based on the observed temperature, salinity and density data. To find out the main factors causing SD in the bay, we computed the rate of potential energy balance of the surface heat flux, tidal and wind stirring proposed by Simpson and Hunter (1974) and Simpson and Bowders (1981) using observed data. It was found that the energy of the wind stirring was one - order smaller than those of the heat flux and the tidal stirring. It means that the variation of stratification phenomena in the bay mainly depend on tidal stirring and sea surface heating in summer if there was no exceptionally strong wind event like a typhoon. Finally, we tested the effects of typhoon on the mixing characteristics of the bay using the example of a empirical typhoon model. It was found that when wind speed is larger than 15m/sec in Deukryang Bay, the wind energy was always larger than the average heating energy based on empirical typhoon model test. Particularly, typhoon passed on the left side of the bay, strong wind energy happened, which is almost the same as tidal energy of spring tide.
