This study has focused 302 environmental ordinances enacted from 1974 to 2008 by 16 upper-local governments (7 deignated cities and 9 provinces) and the relationships between them and the development of the Korean local autonomy system. The ordinances have been categorized into three types, the voluntary ones without any obligatory stipulations in laws, the optional ones based on laws, and the law based obligatory ones, which have been examined the enactment years and the contents of them. The local ordinances have been enacted in four periods with a few characteristics, which are "the pre-local-autonomy period (1974-1991)", "the introductory-local-autonomy period (1991-1995)", "the local-autonomy-developing period (1995-1999)", and "the mature-local-autonomy period (after 2000)", along the local autonomy development. 57 ordinances were enacted in the first period, 20 enacted in the second period, 46 enacted in the third period and 179 ordinances in the fourth period. The obligatory ordinances were the most in the first period and in the second period, while the voluntary ordinances were enacted most in the third period. 7 designated cities have pretty more ordinances, 160 in all, than 9 provinces, 142. The tendency to enact earlier in the metropolitan area, SeoulCity, IncheonCity and Gyeonggi province, than the others can be seen. It can be said that the establishment of the local autonomy in Korea had accelerated the development of the local environmental management.

This study concentrates on the growth & developmental status of low birth weight infant for help their growth & development. Thus it can be provide a direction for scientific health education and counseling materials by investigating factor of growth & development. The subjects for this study were made up of 40 low birth weight infant who attended the well baby clinic of E university Hospital. The study method used was a questionnaire ＆ anthropometric assessment and DDST for normative data of development. The period for data collection was from July 1st to August 31th, 1982. Analysis of the data was done using percentages, $\chi$$^2$-test Stepwise Multiple Regression. The results of study were as follows. 1. The mean weight of birth was 2,068gm and mean of gestational period was 35.65 weeks. 2. The age at which weight ; 32.5%, head circumference : 67,5% chest circumference : 55.0%, height : 50. 0％ was normal range of physical growth. 3. The reverse age at which social development ; 87.5%, fine motor & adaptive development ; 70.0%, gross motor development ; 72.5% of children Passed by DDST to determine of normal range of development. 4. In the among variables, it was found that the infant who were the higher emotional & verbal response of mother and stimulus environment was the more normal range of weight & development than who was not. 5. The stepwise Multiple Regression between developmental status and predictors-birth order, weight at birth, sex, antenatal care, gestational period-are accounts for 34.1%.

Shenyang was one of the representative transportation hub of Northeast China during the modern period. The formation and development of the railway network gave great influence on Shenyang's city development. In order to understand the relationship between railway and city development, first, we classified Shenyang's city development period by the railway network's formation and expansion process. Then, we analyzed the relationship between railway and city space by five categories. The results of this study are as follows. First, before railway was constructed, Shenyang was a castle city, which also was the economic center of Northeast China. This was the main reason Shenyang was chosen as a railway zone. During the modern period, the castle structure became an obstacle to city transportation and environment, therefore, it was disposed. During the period of railways' expansion, South Manchuria, Jingfeng and Shenhai railway line was constructed in Shenyang. Since each line had different operation organizations, city sites along the railways were planned separately. However, these operation organizations had one common purpose, which was to use railway as an accelerator for economic development. During the period of railway's military usage, railway was reorganized as military supply transport for the Japanese, which also was used as a tool for the expansion of colonialism. Second, after Shenyang's city space was reconstructed along the railway, it created a close connection with city structure, city facilities, landscape and city transportation system. Hence, the railway system played a key role in modern city planning.

This study is to investigate the correlation of the period of child care support agency and child language cognitive development and to lead the development of the child in a positive side. For this purpose, Korea Children's Panel's 2012 data by the Korea Institute of Child Care and Education (KICCE) were used, selected 913 children of total 1703 parts. The result was derived from the results of frequency analysis, t-test, one-way ANOVA and multiple linear regression analysis. Analysis result, there was significant correlation between the period of child care support agency and child language cognitive development, and the longer the period of child care supper agency was the better child language cognitive development. Applying this results in health policy to expand the 'Free Childcare Policy', it will be higher for young child language and cognitive development.

Reproductive cycle of the blue-striped angelfish, Chaetodontoplus septentrionalis were histologically investigated. Fish were monthly collected in the coastal waters of Munseom, Seogwipo, Jeju-Island from February to December 2018. The gonadosomatic index (GSI) increased from May and maintained high values in August. The reproductive cycle of female fish can be classified by the characteristics observed during gonadal development as followed: growing stage (November to June), early mature stage (May to June), mature and spawning stage (June to September), and degenerative and recovery stage (September to December). In the male, testicular development period was similar to that of ovarian development period, but mature and spawning period was one month longer from June to October. Fecundity of mature female ranged from 4,601 to 22,840 and was correlated positively with total length and body weight. The histological analysis of gonadal development indicated that the C. septentrionalis was summer-spawning type and is considered a multiple spawner during spawning season.

The aim of this study was to compare community structure of larval fish species in the northern East China Sea during normal meteorological conditions in autumn 2009, during the El Ni$\tilde{n}$o period in 2009-2010, and during the La Nina period in 2010. Fifty taxa were recorded during the study period; the most dominant species were Benthosema pterotum and Gobiidae spp. In October 2008 during the normal period, warm water from the Tsushima Warm Current (TWC) intruded more into the surface and middle layers, and cold water affected by the Yellow Sea Cold Water (YSCW) intruded into the bottom layer. In October 2009 during the El Ni$\tilde{n}$o period, intrusion of the China Coastal Water (CCW), which has low salinity (<32.2 psu), was more apparent than intrusion of the TWC or YSCW. In October 2010 during the La Nina period, intrusion of the TWC and CCW was relatively weak, resulting in the lowest temperature and highest salinity observed during the study period in the eastern part of the study area. Hierarchical cluster, one-way ANOSIM (analysis of similarities), and SIMPER (similarity-percentages procedure) analyses provided two main results. First, the abundance of the most dominant larval fish species in autumn of the normal period was greater than that in autumn of the El Ni$\tilde{n}$o/La Nina periods, resulting in a significant difference in ichthyoplankton community structure between the periods. The abundance of Benthosema pterotum increased in the normal period, possibly influenced by the intrusion of cold water from the YSCW; the abundance of species residing in Korean waters (e.g., Gobiidae spp.) probably decreased during the El Ni$\tilde{n}$o/La Nina periods. The second finding was that the abundance of subtropical larval fish in autumn of the normal period was generally larger than that during autumn of the El Ni$\tilde{n}$o/La Nina periods. This could have been induced by the stronger intrusion of warm water from the TWC during the normal period. Although differences in oceanographic conditions between El Ni$\tilde{n}$o and La Nina periods were observed, the differences in ichthyoplankton community structure between the two periods were not significant.

Larvae of Palaemon serrifer were reared in the laboratory under three different temperature regimes ($15^{\circ}C$, $20^{\circ}C$, $25^{\circ}C$) to study the effects of rearing temperature on larval survival and growth, as well as other traits such as embryo volume, number of embryos (fecundity), incubation period, development. Mode and development period. Growth pattern was analyzed by measuring the molt increment and intermolt period. The intermolt period consistently increased with size and instar number and was shortest at $25^{\circ}C$. However, molt increments generally decreased with instar number. Number of embryos varied from 552 to 1355. The relationship between the number of embryos and carapace length was expressed by the equation (fecundity) y=2.7744x+0.208 ($R^2$=0.7961). Egg volume was a primary factor affecting other life-history traits. Egg volume was $0.078\;m^3$, which is relatively small thus embryos exhibited a relatively short incubation period and a comparatively short development period, and the nutritional mode was planktotrophic. Brood production was followed by a fast parturitional pattern. Most ovigerous females had mature ovaries when the parturial molt occurred soon after eclosion.

The purpose of this thesis is to trace the development of cotton Early Chosun Period by examining the historical literary sources : such as production of cotton various uses of cotton trade with other countries The developement process of cotton fabrics during this period can be divided into three stages. The first stage which can be discribed as a settling period lasted 27 years from A.D. 1392 to 1418. In this stage cotton fabrics were just about to be used as fabrics for popular clothing. The second stage which can be discribed as a developmental period lasted 50 years from A. D.1418 to 1468. In this stage cotton fabrics were mainly produced in the southern parts of the country which are Kyungasng-Do, Choongcheng-Do and Jeunla-Do. And cotton fabrics were used not only by the common people but also by the royal family. The third stage, that is the last one was an extensive period and lasted from A.D.1469 to 1592. In this stage as the demand for cotton fabrics greatly increased the production from southern parts of the country fell in short of the supply needed. Therefore the production was extended to the northwestern parts. In addition cotton fabrics finally came to be used as money to value the goods.
