Sanitary evaluation of seawater and Pyropia sp. laver collected from the five major laver growing areas in Korea was performed four times over the course of a year. The seawater quality in four of these five areas was regarded as the clean area according to Korean criteria, but the seawater at one investigation site in Seoheon area was found to exceed the standard for fecal coliform. In the bacteriological safety analysis of laver (raw source), the percentages of samples not conforming to Chinese criteria at the five sites were 55.6% (Seocheon), 70.0% (Shinan), 81.8% [Jindo (Haenam)], 63.6% (Wando), and 28.6% [Goheung (Jangheung)]. Pathogenic bacteria were not detected in all laver samples. The food safety of laver (raw source) based on heavy metal concentration was confirmed using Korean criteria; the concentrations of heavy metals in laver samples collected from the major laver growing areas were 0.008-0.632 mg/kg wet weight (ww) lead, 0.024-0.137 mg/kg ww cadmium, 0.908-2.892 mg/kg ww total arsenic, and 0.003-0.013 mg/kg ww total mercury. Therefore, pollution source management and periodic monitoring of heavy metals may be required to improve the food safety of laver produced in these laver growing areas.

By using the plasma, which is operated by high temperature arc plasma torch, we tried to make an investigation for discomposing characteristic of PFCs gas flow. As we tried to get some information of each discomposing efficiency by each of electric power of PFCs gas flow, the quantity of flow of fluid, and the quantity of N₂, we found that the discomposing efficiency has been decreased when quantity of flow of each PFCs gas flow were increased under the same electric power in plasma reactor. Also as we generated the plasma with supplying Na gas and CF₄ gas, 96% more of decomposing efficiency of CF₄ were increased by contrast with electric power. As we made an experiment by using high temperature arc plasma which are operated by plasma torch, it seems to be required over 20㎾ electric power for high decomposing efficiency of PFCs gas flow (SF?, NF₃, CF₄) from semiconductor process emissions.
『세비야의 이발사 Le Barbier de Séville』 : 실재 Être와 외관 Paraître의 카니발적 역동성

보마르셰는 그의 첫 희극작품이 흥겨움으로 지배되기를 바랐다. 이 흥겨움은 기존의 질서와 권력을 전복하는 카니발적 의미의 그로테스크를 통해 생산된다. 피가로는 이 희극의 주체로, 알마비바는 가면을 통해 실재와 외양이 뒤바뀜으로써 변화와 생성의 욕망을 표현하는 웃음이 발현된다. 그들의 변신은 사회제도를 비틀어보는 그로테스크의 본질에 대한 은유이며, 세상의 법칙과 권력의 원리를 시대의 변화에 따라 다른 것으로 바꾸어야 한다는 작가의 의지와 맞닿는다. 하인과 주인의 역동성과는 달리 바르톨로와 바질은 우스꽝스러운 그로테스크를 구현한다. 변화는 기괴한 현상으로, 변신을 추구하는 자들은 적으로 삼는 이들은 바로 그러한 의미에서 반계몽주의적 인물들이다. 그로테스크의 전복성과 미래지향적 개방성, 자신 안의 타자를 가면으로 드러내기, 바르톨로와 바질의 기계적 순응성은 『세비야의 이발사』가 드러내는 진실임이 분명하다.

We analyzed how middle manager's leadership behavior according to formalization structure of organization had influence on follower's job performance in this study. By multiple regression analysis in case of middle managers when the level of formalization was higher than low, it was confirmed initiating structure behavior of leader had a certain influence on job performance of follower. In case of middle managers when the level of formalization structure of organization was high, initiating structure behavior of leader elevated follower's job performance. Especially this study supported that such variable as formalization appeared to be situation factor which had influenced the relationship between middle managers' initiating structure behavior and followers' job performance at local administrative organizations in Korea. In conclusion this study suggests us the need to introduce structural situation variable such as formalization in organization for elevating followers' job performance.
