Squid jigging fishery is very important in that there are about 1,000 jigging vessels more than 10 tonnage and about 5,000 ones less than 10 tonnage in Korea. But the cost of oil which is used to light fishing lamps, goes significantly up to almost one hundred million won for 50 tonnage vessels and forty million won in case of vessels less than 10 tonnage. This cost has almost taken 40% of total fishing costs. That is, the fishing business condition of squid jigging fishery is recently in the very difficult situation. As oil price increases, the business condition of the fishery gets worse and worse. Therefore it is very urgent to develop an economical fishing lamp, to solve this problem of fishery's business difficulty. This research aims at developing a fishing lamp for squid jigging fishery using the light emitting diode which has very excellent efficiency and durability. We made a water tank with 20 meters width which is a shape of raceway to research behavioral characteristics of Japanese flying squid to LED light, and made an experiment to investigate optimum wave of LED light to lure squid. The method is to establish LED lamps on both ends of water tank and to observe squid's behavior. Colors and wave lengths of LED lamps, used in experiment, are red(634nm), yellow(596nm), green(523nm), blue(454nm) and white(454nm+560nm). In experiment for attractive capability of LED lamp to squids, Japanese flying squid are highly attracted to blue lamp and white lamp. However, they are dispersed to red and yellow lamps. In addition, Japanese flying squid have moved and stayed in both dark ends of water tank. When compared intermittent lamp with continuous lamp, Japanese flying squid are highly attracted to intermittent lamp when intermittent interval is 0.25 second.

In order to develop the substitutive materials for natural baits of swimming crab pots, the attracting effects of swimming crab such as the preference of baits which were made of the by-products of marine and stock raising through the water tank experiments and fishing experiments. On the investigation of mean entrapped catch number to the pot by the baits after putting the 4 kinds of baits, mackerel(M), mackerel with grinded mackerel s internals(MMI), mackerel with tuna s internalsMMI) and makerel with grinded krill(MK) each in one pot by turns, MMI and MK were entrapped mean 3.9(13.0%) and they were a little more comparing to M, and MTI is least with mean 2.1(7.0%)(F=12.913, P 〈 0.05). Otherwise, on the preference investigation of swimming crabs by the baits after putting the 4 kinds of baits in the 4 pots each, M was entrapped mean 3.0(10%), but MMI, MTI and MK were mean 1.2(4.0%), 1.0(3.3%) and 1.5(5.0%) each and they were only 30-50% of M(F=13.398, P 〈 0.05). On the preference investigation of swimming crabs by the 5 kinds of baits, mackerel(M), and krill(K), manila clam(MC), pig s fat(PF) and chicken s head(CH) which were used in substitutive baits, M was entrapped mean 3.2(10.7%), but K was about 50% of catch of M with mean 1.6(5.3%), and MC, PF and CH were very few with mean 0.1-0.2(0.3-0.7%)(F=89.186, P 〈 0.05). On the preference investigation of swimming crabs by the pots which were put each the 3 kinds of baits, original krill(K), grinded krill with gluten and soybean oil cake(KGGS) and grinded krill with gluten, soybean oil cake and glycine(KGGSGL) in the blue fluorescent hexahedral plastic bait cages(BF), and which were put the mackerel(M) in the non-fluorescent hexahedral red plastic bait cage(RFN), it was entrapped mean 3.0(10.0%) in the pot which was put the mackerel in the RFN, and the same level in the pots which were put the K and KGGSGL in the BF, but it was mean 2.0(6.7%) in the pots which was put the KGGS in BF and it was decreased by 30% of catch comparing to RFN(F=3.750, P 〈 0.05). On the preference investigation of swimming crab by the pots which was put grinded tuna with gluten, soybean oil cake and glycine(TIGSGL) in the blue fluorescent hexahedral plastic bait cage(BF), and which was put mackerel(M) in the nonfluorescent hexahedral red plastic bait cage(RFN), it was entrapped mean 3.3(11.0%) in the pot which was put mackerel in RFN, and mean 2.7(9.0%) in the pot which was put TIGSGL in BF and it was about 15% less comparing to use bait M(t=1.387, P 〈 0.05). As a results of fishing experiments, a plan for enhancing catching efficiency of TIGSGL will be required because catching efficiency of TIGSGL, alternative bait, was half of fish catching efficiency of natural bait using mackerel. Fishing experiments were conducted 3 times using reinforced substitutive artificial bait that is reinforced attractive effect of TIGSGL and composed of tuna intestine, grinded mackerel, gluten, soybean cake, glycine and alanine(TIMGGSGLA). Catching efficiency of TIMGGSGLA was about 80% of that of natural bait made of mackerel.

Since 1884, many western Protestant missionaries came to Korea. The missionaries initially treated of the spiritual perspective of Koreans as superstitious and ignorance-oriented. Especially in the field of medicine, the Western perspective seemed to be far advanced than the Korean traditional perspective. According to the Korean traditional view, sicknesses was in many cases caused by intrusions of spiritual beings. Therefore, to cure the sick, one had to cast out those spiritual beings out of the bodies through placations or by force. With such perceptions, Korean people were not able to overcome the hard situations caused by the contagious diseases such as pestilence, small pox, and typoid fever. Western missionaries could take advantage on those matters in order to help Koreans and thereby achieving the trust of Korean government. Even though Western science and medicine proved their effectiveness through such medical works, excessive reliance can cause one to fall into the idolatry of worshipping medicine instead of God. Throughout the development in the area of science and technology, Westerners have tended to look everything through the scientific perspectives. Through such trends Western societies were believed to run the course of secularization throughout the 19th and 20th centuries. God and His supernatural world have been marginalized especially in public areas. According to Professor Paul G. Hiebert, even missionaries with severe Western cultural backgrounds have difficulties in understanding the spirit world of the native people. Early missionaries to Korea were not exceptions. They also had difficulties when they first met the Koreans and tried to understand their spiritual view points. In contrast to the Westerners who generally do not recognize the spiritual beings around them, the Koreans recognized the spiritual beings such as ghosts, ancestors in almost every aspect of their lives. Koreans were famous in maintaining the practices related to such spiritual beings throughout their ancient history. When the missionaries first observed practices related to the spiritual beings, they judged Koreans to be ingnorant or superstitious. However, the missionaries continuously tried to understand the people and their worldviews. When they were unable to understand the Korean worldview on the spiritual beings, they resorted not to the Western naturalistic perspective but to the Bible. Through comparison between the Korean traditional perspectives and the Biblical perspectives, they discovered that the Biblical perspectives were more similar to the Korean traditional perspectives. And with careful observation and examination of the Korean ministers’ deliverance works, they changed their thought about the spirit world. The demons and spiritual beings which were regarded to harass Korean people were not supterstitions or fatacies. They were real beings confirmed by the Bible. The native Korean ministers contributed a lot in the paradigm shift from Western perspective to the Korean perspective on the reality of spiritual beings. The Korean ministers viewed the Bible differently. They believed Bible stories where the possessed were released by Jesus and his disciples. The faith of Korean ministers proved to be simple and firm enough to follow the practices of Jesus and his disciples in casting out demons. When the missionaries heard about the stories of deliverances by the Korean ministers and believers, they did not stop but rather carefully examined such behaviors in light of the Bible. The final criteria of missionaries were not the western but the Biblical perspective. With such criteria, they accepted and recognized the deliverance ministries of the Korean believers. Some missionaries, when asked if they could cast out demons out of troubled, succeeded in the deliverance ministries. In my estimation, the Nevius mission plan contributed greatly in making harmony and cooperation between the missionaries and the Korean ministers. God brought Koreans who were troubled with spiritual bondage into the Kingdom of God through such faithful servants of God. The reasons the early protestant missionaries to Korea brought such great success in evangelizing Korea were foremost their deep reliance to the Bible as the Word of God and secondly their deep understanding of Koreans and their ways of thinking.

Growth behavior of InGaN/GaN self-assembled quantum dots (QDs) was investigated with respect to different growth parameters in low pressure metalorganic chemical vapor deposition. Locally formed examples of three dimensional InGaN islands were confirmed from the surface observation image with increasing indium source ratio and growth time. The InGaN/GaN QDs were formed in Stranski-Krastanow (SK) growth mode by the continuous supply of metalorganic (MO) sources, whereas they were formed in the Volmer-Weber (V-W) growth mode by the periodic interruption of the MO sources. High density InGaN QDs with 1~2nm height and 40~50nm diameter were formed by the S-K growth mode. Dome shape InGaN dots with 200~400nm diameter were formed by the V-W growth mode. InN content in InGaN QDs was estimated to be reduced with the increase of growth temperature. A strong peak between 420-460 nm (2.96-2.70 eV) was observed for the InGaN QDs grown by S-K growth mode in photoluminescence spectrum together with the GaN buffer layer peak at 362.2 nm (3.41 eV).
