In Korea, the collapse of traditional Patriarchal family system has caused the weakening the patriarchal authority which represents the decrease of traditional attitude of respect for old age, influenced by the strong tendency of Materialism in ethics. The urgent problem is how to solve the conflicts of the alienation almost every old people has felt from the society and family which they belong to and how to harmonize the respect for old age who used to have had in the past. From 21st to 30th of July 1979, I explored the small village in Cheju Island with eight students which I selected on purpose that village had preserved the traditionalism. I collected the interview data form a sample of 221 persons of the village in Cheju Island. I studied this small village in Cheju Island for the intention of suggesting the ideal model of regional society which both traditional and non-formal, although the phenomena of nuclear family system and materialism and industrialism are overwhelming in ur present society. Generally people in Cheju Island are economically poor and major occupation is farming, since the industrialization proceeds very slowly and there still strongly remains the traditionalism. Alienation and dissatisfaction of old people from their family and society in Cheju island are less common in comparison to the main land. Old people in Cheju Island usually value the importance of labour. Divison of labour has been well observed in farming, and men and women in Cheju island are equally regarded in comparison to the main land. Old people are independent economically and spiritually from their offsprings and they organize the nuclear family system firmly. Also the old generation is ready to compromise with the new generation and they defy the authoritariansim.

Morphotaxonomic study was made on the Leathesiaceae of Cheju Island. One species of Petrospongium, P. rugosum, and three of Leathesia, L. difformis, L. sphaerocephala, and L. verruculiformis, were found in Cheju Island. Myriactula species was not found in the locality. L. verruculiformis was described as a new species of the genus Leathesia. L. verruculiformis was characterized by the less compact cortical layer, clavate assimilating filaments, and plurilocular sporangia born in tufts.

The characteristics of spring machanism In the Cheju Island were analyzed by statistical techniques. Basic characteristics, areal and altitudinal variations, and correlations of spring data were investigated. In this study. however, the subjects of the study are the 451 springs, the whole basin of Cheju Island derided Into four groups. In this study, analyzed the spring phenomena on the basis of both the geologic elements and the topogaphic elements. Also, the spring zone In Cheju Island are classified Into three types that the mountain area, the muddle area, the coastal area in spring distribution by attitude. The quentity of spring and variability show subvariety on the average according to Meinzer's classilfication and the whole basin of spring shows various distributions from Third to Sixth. The results of this study can be utilized to evaluate the condition of groundwater development In Cheju Island.

As the electrical power industry is restructured, the electrical power exchange is extended. One of the key information used to determine how much power can be transferred through the network is known as available transfer capability (ATC). To calculate ATC, traditional deterministic approach is based on the severest case, but the approach has the complexity of procedure. Therefore, novel approach for ATC calculation is proposed using cost optimization in this paper Cheju Island interconnected HVDC system with mainland in KEPCO (Korean Electric Power Corporation) systems, and the demand of Cheju Island increases about 10 ($\%$) every year. To supply for increasing demand, the supply of HVDC system must be increased. This paper proposed the optimal transfer capability of HVDC system between Haenam in mainland and Cheju in Chju Island through cost optimization. The cost optimization is considered production cost in Cheju Island, wheeling charge through Haenam-Cheju HVDC system and outage cost with one depth (N-1 contingency)

Purpose: The purpose of this study was to provide a fundamental data for improving nurses' working environment and securing quality of nursing care. Method: It was consisted of analyzing education system and employment status of nursing personnel, and focus group interviews in Cheju Island. Results: Total graduates were 4,139 by 2006 from two nursing schools in Cheju. Difficulties in working conditions from focal group interviews were classified into four categories; Lack of anonymity of nurses, the burden from performing nontraditional nursing roles due to shortage of physicians, irregularity of working schedule and too many night shifts for taking care of female colleague's condition related with pregnancy, and poor support for implementing and developing professional nursing. Conclusion: A survey revealing working condition of nursing personnel of all health care institutions in Cheju Island will provide the comparison between Cheju Island and other areas. It needs to cultivate the public opinion about the importance of quality of nursing care proceeded by the broad support for improving nurses' working environment. It is essential to support continuing education to bring professional nurses and establishing the system to utilize them to overcome the shortage of physicians in Cheju Island.

In order to carry out a systematic study of ascidians in Cheju Island, the authors identified and classified specimens collected from 11 sites around Cheju Island from December 1 1969 to January 1989. Using the information gathered from this study as well as previous s studies, the authors prepared a detailed list of the ascidians of Cheju Island. A As a result of this study, the ascidians of Cheju Island are 50 species in 10 families. Among them, 3 species (Dideηmum apersum, Didemnum translucidum, Botrylloides perspicuum) had not previously been known to exist in Korean waters. Description and drawings of these three species are presented in this report. It was also discovered that ten of the fifty species are found only in the Cheju Island area. The fifty species recorded in the Cheju Island area account for 68% of the seventy three species recorded from all Korea. Classifying them by t the temperature of the water where they are found, the authors found the following: one cold water species (2% of the total), seven cold-temperate water species (14%), thirty eight warm-temperate water species (76%) and four tropical water species (8%)

The marine hydroids of Cheju Island in this work identified into 46 species and/or subspecies of 25 genera in 10 families. Of which four species: Rhizocaulus chinensis, Obelia bicuspidata, Sertularia desmoides and Plumularia spinulosa are new to the hydroid fauna of Cheju Island and four species: Hebella parastica, Campanularia groenlandica, Campanularia everta and Sertulareffa natalensis are new to the Korean fauna. Adding these eight species to the previous known species (83 species and/or subspecies) in Cheju Island, the hydroid fauna in Cheju Island identified up to date consists of 91 species and/or subspecies of 41 genera in 12 families. Macrorhynchia phoenicea is dominant species which occur in 10 points, Aglaophenia suensonii in eight points. 71 species (78%) occur in Songsanp'o, 43 species (47%) in Munsom, 26 species (29%) in Supsom, 13 species (14%) in Wimi-ri and 11 species (12%) in P - omsom in order. Thirty-three percent (30 species) of the hydroids of Cheju Island was only found in Cheju Island.
