The total suspended particles (TSP) collected at the 1100 site of Mt. Halla have shown higher compositions for the anthropogenic components followed by marine and soil originated ones. The concentrations of the soil originated nss-$Ca^{2+}$, Al, Fe, Ca components have been increased in spring, and the anthropogenic $NH{_4}^+$, $K^+$, nss-$SO{_4}^{2-}$ components showed high concentrations in June. Meanwhile, the concentration of $NO{_3}^-$ as same as nss-$Ca^{2+}$ was higher in spring. It's likely due to the influence of its long-range transport from China. Compared to the non-Asian Dust periods, the concentrations of nss-$Ca^{2+}$, Al, Ca, and Fe have been increased 7.2~9.5 times in Asian Dust storm periods, and those of nss-$SO{_4}^{2-}$ and $NO{_3}^-$ were 1.3 and 3.8 times, respectively. From the factor analysis, the TSP compositions were influenced mainly by anthropogenic emission sources, followed by oceanic and soil sources. The backward trajectory analysis has shown that the concentrations of the anthropogenic and soil components were increased when the air parcels had been moved into Jeju island via China in a northwesterly wind.

Samples were obtained with a set net during 7 months between March and October in 1987 off the coast of Hwasun, southern part of Cheju Island. Most of organisms, representing 36 species, were less than 20cm(96%) in length, and 30g(74%) in weight. The four most abundant species were jack mackerel, Trachurus japonicus ; squid, Todarodes pacificus ; mackerel, Scomber japonicus ; and Apogon semilineatus, which comprised about 89% of the total individuals and about 70% of the total weight. Diversity index, the number of species and information index for individual were high in early spring, even though biomass was not abundant. On the other hand, diversity index and information index for individual were relatively high in August in spite of low occurrence of the species number. A cluster analysis of 24 species which appeared more than twice during the 7 samplings were illustrated from the similarity matrix. All of the 24species were grouped at the 0.14 similarity level. They were divided into four groups at 0.50 level.

In order to elucidate the mechanism of fishing condition variation of anchovy in the set net fisheries of Anggang Bay, the monthly catch of anchovy was analyzed and examined based on the data acquired from 2006 to 2010 in 13 different fishing grounds. Anchovy consistently appeared from April to December and reached the production of 840 to 1,424 t (average : 1,228 t), with a big annual variation. However, anchovy production in this area accounts for approximately 75% of the production by set net in Anggang Bay whereas it holds 6.8% of the nationwide production (=18,034 t) by set net. The school of anchovy starts to appear in April at the west mouth of the bay and move north-eastward. Afterward, having three of clockwise turns in the middle of the bay, they scatter to swim into the deep place of the bay and finally go out to turn back to their coming way. These behaviors of anchovy are likely related to thermal fronts as well as distributions of food. The production of anchovy (y, kg) relied greatly on frequencies of effective northeasterly ($x_1$) or northwesterly ($x_2$) wind (${\leq}$3.5m/s) which blow between April and June. Their relationships are as follows: $y=1086.27+21.499x_1-15.16x_2$ (r=0.901). Consequently, we concluded that the northeasterly wind, which appears in the breeding season of spring, played a role to retard the movement of anchovy school to the eastern sea, while the northwesterly wind inhibits the invasion of anchovy school into the bay.

With the recent increase in the number of foreign settlers in our country, we need a societal system which they can adapt well in. In order to successfully settle in our society, the marriage immigrants who especially plan a life in a new environment should be supported with support programs, especially to help them adapt to their very basic housing environment as their daily environment. From this research, through a program analysis of multi-cultural family support centre, the societal support helping to adapt to the residential environment for marriage immigrants in each nation was examined, and grasp an understanding on their adaptation to the housing environment by conducting interviews about housing environment adaptation examples. From the result of analyzing the 100 programs of the multi-cultural family support system, it could be seen that for the marriage immigrants to adapt, various programs are needed. In other words, there are effective programs for the early settlement of the marriage immigrants such as Korean education, tradition culture education, provision of district daily information, but it could be seen that heavier education was needed for, than for the sake of the marriage immigrants who took such education. Through adaptation case examples of 8 marriage immigrants from 5 different countries, it was realizable that the housing problems the marriage immigrants go through, are not limited to themselves, but also are related to the safety of their family and adaptation problems with their children. Therefore, by developing an adaptation program to help with housing environmental adaptation, the lives of the marriage immigrants' families will be supported, and will support early settlement, which then basic preparation for human resources as district societal use will be needed. By developing a program with a housing environmental professional, and if there is a positive effect and achievement, it is expected that there will be a standard program system available for all marriage immigrants.

A history of Chinese Costume is that of the accept and the struggle between the 'Shen- Yi' of Han(漢) race and 'Ho-Bok' of foreign races. There are the 'Shen-Yi Ko' and the 'Ho-Bok Ko' in their representative documentary. They are quite significant materials for the researchers of the Oriental costume. The purpose of this study about comparing and analyzing the 'Shen-Yi Ko' and the 'Ho-Bok Ko' give a guidance to Chinese costume's researchers. The results of study are as follows: The 'Shen-Yi', having made a dress joined an upper to the low clothing together(上衣下裳) and deeply covered the parts of all the bodies, was named, had appeared the Spring-Autumn & warring state period(春秋戰國時代) and later the former Han Dynasty(前漢). Not only everyone in spite of men and women, without distinction of rank, high and low alike but also even the court dress(朝服) and from latter Han Dynasty(後漢) only the housewives could have worn it. The 'Shen- Yi Ko' disappeared its records and remains and at present nothing leave behind. The 'Ho-Bok' is a costume of the nomadic horse-riding people among the foreign races, then influenced upon the Chinese costume. The style of the Chinese costume consists of 'Yi Sang'(衣裳) and the 'Ho-bok' of foreign races, 'Yi Ko'(衣袴). The 'Yi Ko'((衣袴), derived from the King Muryoung of Cho Dynasty, had greatly been changed the chinese men's clothing and After that 'Ko Sup'(袴褶). The Chinese have enjoyably and familiarly the accepted 'Ho Bok' for a long time.

With the growing traffic density and increasing comfort requirements, the automation of the drive train will gain importance in vehicles. The automatic clutch actuation relieves the drivers especially in urban driving and stop-and-go traffic conditions. This paper describes the dynamic modeling of a clutch actuator and clutch spring. The dynamic model of the clutch system is developed using MATLAB/Simulink, and evaluated by experimental data using a test rig. This performance simulator is useful to develop the clutch-by-wire (CBW) system for an automated manual transmission (AMT). The electro-mechanical type CBW system is also implemented as an automatic clutch for AMT. The prototype of CBW system is designed and implemented systematically, which is composed of an electric motor, worm gear and slider-crank mechanism. The test rig is developed to perform the basic function test of the automatic clutch, and the developed prototype is validated by the experimental data on the test rig.

A Double Facade System(DFS) is well known as an innovative solution of ecological facade in the west european countries. There are more than 200 various realized DFS in Germany. At the same time, the korean engineers have researched to find out the physical advantages of DFS in the moderate korean climate, which has a very humid summer with high temperature and a dry winter with low temperature. For example, the monthly mean temperature in Korea comes up to 28K, while that in Germany comes up to only 19K. That is, why a other solution of DFS is needed in Korea. This study has experimented the physical performance of the natural ventilation in the heating period. The preheating function of the cold air by DFS can improve no doubt the performance of the natural ventilation at the cold season as well as spring and autumn. The physical difference between single and double facade on natural ventilation has been tested at the newly constructed laboratory, which can turn $360^{\circ}$ to confirm the characteristic of a facade with the various directions. The results show the natural ventilation of the DFS has definitely much more comfortable than that of the single facade system. The air velocity of the inflow as well as the air temperature in the DFS provide a more stable condition than in the SFS. The theoretical limit(air velocity max 0.2m/s, air temperature min. $18^{\circ}C$, temperature difference between 100mm and 1700mm height max. 3K) on the indoor comfortableness doesn't go over in the DFS. On the other hand, the SFS showed an unstable condition with an excess of comfortableness limit on air velocity as well as temperature. In view of the researching results so far achieved, the research came to a conclusion, that the DFS can provide a more comfortable indoor condition by the preheating in the heating period than a SFS, and the period of natural ventilation in winter time could be definitely increased at the DFS.

As of 2018, total yield of lettuce and strawberry amounted to 93,543 tons (representing 1.0 percent) and 183,639 tons (2.0 percent), respectively, among total yields worth 9,185,889 tons in South Korea. Lettuce is affected by a combination of numerous elements such as varieties, cultivation methods and pests during each growth phase (Lee et al., 1999). It is mainly cultivated in spring and fall. Especially due to respiration rate after harvest leading to reduced quality and poor storage, maintaining annual supply is unavailable (Jang et al., 2018). With the distribution of new varieties, forcing culture and indoor insulated facilities for plant cultivation during winter, strawberries are produced every year except for late summer and early fall. Due to active respiration, transpiration, soft flesh and high water content, the fruit is vulnerable to go bad and got rotten compared to other fruits. Furthermore, it is difficult to maintain freshness due to the possibility of softening, discoloration and fungi (Lee et al., 2012). In this regard, developing improved storage and package techniques is needed to ensure maintaining quality and safety even just two to three days after harvest. In order to ensure improved quality and safety of strawberries and lettuce after harvest, the present study applied a modified atmosphere packaging (MAP) technology (Mostofi et. al., 2008). Going forward, it compared the quality and safety of the two products while being stored in a way that put them in an MAP-applied container and a plastic container at room temperature and 4 degree Celsius.
