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.

This study was to investigate the factors which influence foodservice dietitians' job satisfaction and dissatisfaction by the elementary school foodservice type using questionnaires. The results of the study are as followings : 1) Foodservice types of the subjects were urban 49(23.2%), country 141(66.8%) and island 21(10.0%). 79.6% of the urban type were operated by the conventional, independent management system, where 38.3% of the country and 52.4% of the island type were operated by conventional, joint management system. 2) Urban type dietitians showed significantly lower satisfaction on their salary & promotion(1.5) compare to country & island types(p<0.05). Island type dietitians showed significantly lower satisfaction on the student's health improving(2.4) compare to country &urban types(p<0.05). 3) Dietitians of urban type were dissatisfied more 'personnel management(3.2)' than dietitians of other two types. Dietitians of country type and island type were dissatisfied more 'extra work load(2.6)' than dietitians of urban type. 4) Work load was lots orderly island, country and urban types. Working attitudes were the most positive at dietitians of urban type and the most negative at dietitians of island type. 5) Job satisfaction and dissatisfaction of dietitians were correlated with number of meals, number of school transfer, cook license, additional job and school foodservice location type.

Recently, a project to build a carbon zero island with no carbon emissions has been carried out by replacing diesel generators with renewable energy sources in island areas where diesel generators supplied local loads as independent systems. To minimize damage to the lives of islanders, low noise wind generators should be installed by adjusting the rated speed. In islands with low loads, wind turbines that are more efficient than medium-sized wind turbines should be installed. In this study, the generator field analysis and characteristics were analyzed to develop 230 kW-class low wind medium-wind turbine technology. The electromagnetic field analysis program used Maxwell. As a result, the cogging torque was reduced, and the initial maneuver wind speed and loss value were lowered. Hence, the output amount was increased with high efficiency.

Islands that is far away from onshore have used internal-combustion engine driving alternators to secure electric power. However, with Paris convention on climate change, there is a growing interest in eco-friendly energy independent island that replaces microgrid(MG) consisting of photovoltaic, wind power, and energy storage system with alternators for internal combustion engines. And also, national emission trading has been implemented, and the price of certified emission reduction(CER) has a influence on system marginal price(SMP). Because, the low cost generation source decides SMP when CER price is low, while the more expensive generation source decides SMP when CER price is high. Therefore, the increasing of CER price has a strong influence on the annualized return of MG independent power producer. Moreover, the fixed RPS price is implemented from 2017, which the increasing of CER price under the fixed RPS price or the variable RPS price affects annualized return differently. In this paper, the annualized return according to CER price is analyzed for large, middle, and small scaled islands, the effect of CER price on the annualized return was confirmed.

HyangGyo had been built for teaching peoples as a place of educational practice, and also for the order and stability of country through Confucianism. This study analyzed and researched the building structure of Daejeong-HyangGyo in Jeju Island In Daejeong-HyangGyo, unique architectural characteristics are shown as they have been built in an island independent from the mainland. Also up-down system was well reflected in detailed architectural styles. The main temple of Daejeong-HyangGyo was built in the type of one-Chulmok(a subsidiary material of Gongpo and a piece of wood to support the eaves) of which ancon supports a purline from the center of a pillar and two-Ikgong(a piece of wood engraved to put on an ancon), but in the case of the lecture hall, its Gongpo(a piece of wood to support the eaves) was inferior in quality. In the case of Jeju abutments were used in main temples and fire walls were mostly used. In particular, their abutments are difficult to be observed in HyangGyo in the mainland. It is presumed that the abutment and the fire wall used in Jeju Island might be the best solution to protect structures from rain and moisture. To sum up, local characteristics and traditional rules were thoroughly reflected in Dajeong-HyangGyos built in Jeju Island from the aspect of arrangement and detailed style. In conclusion, it is significant that architectural styles, not to mention the other aspects of Jeju culture, were suitably adapted to Jeju Island.

This study was conducted to develop stem volume models for the volume estimation of Quercus glauca Thunb. in Jeju Island, Republic of Korea. Furthermore, this study validated the developed stem volume models using an independent dataset. A total of 167 trees were measured for their diameter at breast height (DBH), total height and stem volume using non-destructive sampling methods. Eighty percent of the dataset was used for the initial model development while the remaining 20% was used for model validation. The performance of the different models was evaluated using the following fit statistics: standard error of estimate (SEE), mean bias absolute mean deviation (AMD), coefficient of determination (R²), and root mean square error (RMSE). The AMD of the five models from the different DBH classes were determined using the validation dataset. Model 5 (V = aD^bH^c), which estimates volume using DBH and total height as predicting variables, had the best SEE (0.02745), AMD (0.01538), R² (0.97603) and RMSE (0.02746). Overall, volume models with two independent variables (DBH and total height) performed better than those with only one (DBH) based on the model evaluation and validation. The models developed in this study can provide forest managers with accurate estimations for the stem volumes of Quercus glauca in the subtropical forests of Jeju Island, Korea.

Objective: This study aimed to determine the predictive performance of non-contrast CT (NCCT) signs for hemorrhagic growth after intracerebral hemorrhage (ICH) when stratified by onset-to-imaging time (OIT). Materials and Methods: 1488 supratentorial ICH within 6 h of onset were consecutively recruited from six centers between January 2018 and August 2022. NCCT signs were classified according to density (hypodensities, swirl sign, black hole sign, blend sign, fluid level, and heterogeneous density) and shape (island sign, satellite sign, and irregular shape) features. Multivariable logistic regression was used to evaluate the association between NCCT signs and three types of hemorrhagic growth: hematoma expansion (HE), intraventricular hemorrhage growth (IVHG), and revised HE (RHE). The performance of the NCCT signs was evaluated using the positive predictive value (PPV) stratified by OIT. Results: Multivariable analysis showed that hypodensities were an independent predictor of HE (adjusted odds ratio [95% confidence interval] of 7.99 [4.87-13.40]), IVHG (3.64 [2.15-6.24]), and RHE (7.90 [4.93-12.90]). Similarly, OIT (for a 1-h increase) was an independent inverse predictor of HE (0.59 [0.52-0.66]), IVHG (0.72 [0.64-0.81]), and RHE (0.61 [0.54-0.67]). Blend and island signs were independently associated with HE and RHE (10.60 [7.36-15.30] and 10.10 [7.10-14.60], respectively, for the blend sign and 2.75 [1.64-4.67] and 2.62 [1.60-4.30], respectively, for the island sign). Hypodensities demonstrated low PPVs of 0.41 (110/269) or lower for IVHG when stratified by OIT. When OIT was ≤ 2 h, the PPVs of hypodensities, blend sign, and island sign for RHE were 0.80 (215/269), 0.90 (142/157), and 0.83 (103/124), respectively. Conclusion: Hypodensities, blend sign, and island sign were the best NCCT predictors of RHE when OIT was ≤ 2 h. NCCT signs may assist in earlier recognition of the risk of hemorrhagic growth and guide early intervention to prevent neurological deterioration resulting from hemorrhagic growth.

The purpose of this study is to interpret a house as material into culture. Main method is an ethnographic interview with dwellers as a part of a participant observation, a kind qualitative study. Significantly two different types of folk housing are discovered in East and West areas of the Cheju Island. In the East, kitchen itself forms a separated building, Jeongji-gori, whereas in the West, kitchen is within a main building, An-gori. Different type of kitchen is formed by the different family system. While independent family system of son and father selects a separate kitchen building as a general rule of Cheju Island, an extended family system between father and son selects same kitchen, Jeongji-gori, in the east area. Natural environment of infertile soil of east area makes family work together and eat together. Inner space of the kitchen building is utilized not only in cooking but also in eating, working, and sleeping. In order to explain folk house type, a 'culture area' concept is suggested. The interrelated 'cultural type' of architecture behind a physical surface 'type' is suggested as a new typology.
