This survey was conducted to monitor the food additives, heavy metals, and microbial contamination of the dried marine products like squids, pollacks, and shrimps, including jerked beef. They were purchased from supermarkets and traditional markets in Gwangju from February to December 2009. A total of 101 samples were tested. Sorbic acid, one of the additives, was detected in 29 samples of them (32.2%) and the contents were from 21.4to 244.2 mg/kg. Among heavy metals, lead was detected, ranging from 0.000 to 0.594 mg/kg and cadmium, from 0.000 to 0.679 mg/kg and mercury, from 0.001 to 0.947 mg/kg. Sodium was detected, ranging from 0.6 to 1.7%. Aerobic bacteria were detected from 81 samples (80.2%), coliform bacteria, from 10 samples (9.9%) and Bacillus cereus,causing food poisoning, was isolated from 3 samples (3.0%).

For an effective management of fisheries resources, we need fisheries informations necessary for the establishment of reasonable fishing effort and TAC distribution. To study the present state of by-catch and discard of gill-net fishery in the East Sea, we carried out fishing research using trammel nets in the coastal sea of Susan-port (Yangyang), Jangho-port (Samcheok) and Hupo-port (Uljin). As a result, a total of catch of Susan was 259,172g and that of Hopo was 577,638g. Thus Catch of Susan was 1.49 times more than that of Hupo considering the number of used fishing gear. And catch of Janho was 7.4 times more than that of Susan considering the number of experiment. Two methods of by-catch analysis in this study were used, one method is standardizing of listed species catching possible in fishing license, another method is regarding catch species under 1% of total catch as by-catch. As a result of by-catch analysis of two method, by-catch rate of Susan was 6.55% and 5.87% respectively, that of Hupo was 44.70% and 5.24% and that of Jangho was 0.96% and 2.31%. Discard rate of fish in Susan, Hupo and Jangho were 1.59%, 3.42%, 2.23% respectively.

The current study examined Ag migration from the Ag paste bump in the SABiT technology-applied PCB. A series of experiments were performed to measure the existence/non-existence of Ag in the insulating prepreg region. The average grain size of Ag paste was 30 nm according to X-ray diffraction (XRD) measurement. Conventional XRD showed limitations in finding a small amount of Ag in the prepreg region. The surface morphology and cross section view in the Cu line-Ag paste bump-Cu line structure were observed using a field emission scanning electron microscope (FE-SEM). The amount of Ag as a function of distance from the edge of Ag paste bump was obtained by FE-SEM with energy dispersive spectroscopy (EDS). We used an electron probe micro analyzer (EPMA) to improve the detecting resolution of Ag content and achieved the Ag distribution function as a function of the distance from the edge of the Ag paste bump. The same method with EPMA was applied for Cu filled via instead of Ag paste bump. We compared the distribution function of Ag and Cu, obtained from EPMA, and concluded that there was no considerable Ag migration effect for the SABiT technology-applied printed circuit board (PCB).

This survey was conducted to monitor the total sugar, sodium, and artificial sweetener contents of light meals from the school zone in Gwangju, from November, 2008 to April, 2009. A total of 100 samples were tested. HPLC/ELSD was used for the determination of total sugar contents and AAS for sodium contents. Total sugar amounts were the sum of both mono-and disaccharide according to nutritional information standard defined by the Korea Food and Drug Administration. The results were as follows by the form of total sugar content(sodium content): 5.7 ± 1.9%(4.6 ± 1.6 mg/g) for Tteokbokki, 7.6 ± 5.1%(5.4 ± 2.7 mg/g) for Chicken(skewed), 15.4 ± 3.2%(3.0 ± 0.9 mg/g) for Bun(fish-shaped), 0.6 ± 0.3%(3.7 ± 1.0 mg/g) for Sundae, 0.9 ± 0.3%(7.4 ± 1.4 mg/g) for Oden(with broth), 20.5 ± 6.2%(2.9 ± 0.6 mg/g) for Waffle, 6.8 ± 2.2%(4.7 ± 1.0 mg/g) for Hotdog, 14.2 ± 2.8%(3.1 ± 1.6 mg/g) for Hotteok, 6.6 ± 2.1%(3.9 ± 0.6 mg/g) for Toast, 10.1 ± 3.7%(2.3 ± 0.7 mg/g) for Fry(sweet potato), 1.6 ± 0.7% (4.0 ± 0.7 mg/g) for Fry(etc), and 9.3 ± 2.4%(4.0 ± 0.6 mg/g) for Doughnut. In addition, sodium saccharin, one of the artificial sweeteners, was tested. Among 60 samples from February to April, 2009, 11 samples had sodium saccharin(6.7~101.0 mg/kg).

Since the end of 1960s, an era of internationalization, Interculturalism has been reflected in intercultural plays which borrow concepts of foreign-cultural aesthetics for the performance and create a new stage language. Among many writers and performers, Oh, Tae-seok created his own unique aesthetic performances through experimental and avant-garde methodologies connected with various areas of art. His plays are worth studying since they suggest us a point of view which helps us to get out of the ordinary, fixed thought and try to see variety of reality. Therefore, our study categorized Oh, Tae-seok’s play into four areas according to grotesquery interculturalism : Evil sprit, Abhorrence, Exaggeration and distort, and Heterogeneity. Based on this category, we analyzed plastic artistic characteristics of his plays’ stage costume, for example, shapes, materials, and color, and tried to enhance the aesthetic value of his plays. We made a conclusion that the play showed grotesquery features in stage costume, which represented death, tragedy, evil sprit of human negligence, surprising and grotesquery abhorrence by deformity of the body, exaggeration and distortion, ridiculousness, and heterogeneity, the mixture of abnormality and unstableness. Our study could help produce adequate stage costume matching the features of the performance, and be the cornerstone of grotesquery aesthetic interculturalism study reflected in stage costume.

This survey was conducted to monitor the safety of children snacks circulated in a stationary store or small shop around the elementary school from March to October, 2008, in Gwangju. A total of 309 samples was tested. Of these samples, 254 were confectioneries, 41 were ready-to-eat foods like kimbap, 4 were beverages and 10 were the others like fishery products. 259 were domestic products and 50 were imported. By the origin of imported samples, 17 were from china, 6 from U.S.A., 5 from india and etc. We found out that in acid value, 2 cases of fried snacks(3.9 and 4.4) proved to exceed regulatory guidance(2.0). And among ready-to-eat foods, two kimbap had Staphylococcus aureus, and one had Escherichia coli, which microorganism could cause food poisoning.

For an effective management of fisheries resources, we need fisheries informations necessary for the establishment of reasonable fishing effort and TAC distribution. We carried out fishing research using trammel nets in the coastal sea of Susan-port(Yangyang, Gangwondo, Korea) and Hupo-port(Uljin, Gyeongbukdo, Korea) and analyzed fishing power variation of the fishing gear in terms of species composition, condition and so on for both sites. A total of 29 species were caught with most dominant species of Hippoglossoides dubius followed by Pseudopleuronectes herzensteini, Lophius litulon and Alcichthys elongatus in Susan. The total number of species caught in Hupo was 37 species with most dominant species of Todarodes pacifius followed by Lophius litulon, Hexagrammos agrammus and Pseudopleuronectes herzensteini. CPUE of Susan fishing area per trammel net was 12.74 fish and 2.00kg on average, while it was 6.80 fish and 2.27kg on average for Hupo. The fishing power index for both sites was 1, placing the two fishing grounds in a same level.

The fishing lamp is a fishing gear that gathers fish at night. But the cost of oil, which is used to light fishing lamp, has been risen significantly up to 30-40% of total fishing costs. Therefore it is very urgent to develop an energy economical fishing lamp in order to solve the business difficulties of fisheries. Under this background, this research aims at developing a fishing lamp for squid jigging and hairtail angling fishery using the LED, which has excellent energy efficiency and durability. The LED fishing lamp developed can be controlled to fix a fit direction of fish shoal deep because a fishing lamp can be adjustable up and down directions. One unit of fishing lamp has about an 80Watt capacity and the frame of fishing lamp is made of aluminium to emit generated heat of LED to outside. The LED lamp developed was highly durable, only 5.7% of emitting efficiency decreased for 18 months. The illuminance of a unit LED lamp was 2,070lux at 1m and 21lux at 10 m distance, and the intensity of LED lamp system emitted 2,580lux and 400lux at the respective distances. After development of this fishing lamp, 100 units are installed on operating fishing vessels. Experimental results show that energy consumption of squid jigging and hairtail angling was reduced by 40% and 87%, respectively. In conclusion, our methods showed elevated fishing power, compared with traditional fishing method: 37.7% for squid jigging and 24.5% for hairtail angling.
