2006/2007년 한반도에 이상적인 온난 겨울을 가져온 원인을 규명하기 위해 동아시아 지역 대기 순환의 특징을 조사하였다. 2006/2007년 겨울철 동안 대기 상태는 시베리아 고기압 및 알류산 저기압의 약화, 한반도 부근으로 하층 남동류의 강화, 일본 남쪽으로 상층 제트의 약화로 특징지워질 수 있다. 이러한 패턴은 시베리아 지역(60-140E)으로 블로킹 흐름이 없을 때 나타나는 대기 상태와 상당히 밀접한 관련성이 있다. 아울러 엘니뇨 및 북극 진동 역시 이런 패턴을 만들어 내는 것으로 보인다. 따라서, 블로킹과 무관한 대기 상태, 엘니뇨 및 양의 북극 진동이 원인이 되어 1958/1959-2006/2007 기간 중 2006/2007 겨울철에 한반도에서 가장 기온이 높았던 것으로 판단된다.

The purpose of this study was to measure the mediating effects of sacrifice, value and satisfaction on the relationship between restaurant service quality and loyalty. A total of 273 questionnaires were completed. Structural equation model was used to measure the causal effects of service quality, perceived sacrifice, value, satisfaction and loyalty. Results of the study demonstrated that the structural analysis result for the data also indicated excellent model fit. The influences of service quality and perceived sacrifice on value were statistically significant. The influences of service quality and value on satisfaction were statistically significant. The influences of value and satisfaction on loyalty were statistically significant. As expected, the service quality had a significant effect on loyalty. The results indicated that the effect of service quality on loyally was mediated by value. Moreover, the effect of service quality on loyalty w3s mediated by satisfaction.

This survey was conducted to illustrate insect pests and their natural enemies in soybean fields in Honam area. A total of 23 pest species in 13 families and 13 species of natural enemy were observed during 2002 to 2003. Delia platura, Medythia nigrobilineata, Spodoptera exigua and Aphis glycines occurred relatively with high population densities during the early growth stage of soybean. Dolycoris baccarum, Riptortus clavatus, Nezara antennata, Piezodorus hybneri and Halyomorpha halys began to occur between mid July to early August and lasted until the harvest time. Lepidopteran insect pests, Leguminivora glycinivorella, Pleuroptya ruralis, Scopula missaria, Macdunnoughia purissima and Spodoptera litura occurred significantly in late August in soybean field. Natural enemies of soybean insect pests observed in this survey were seven parasitoids, five predators, and an entomopahogenic fungus. Two egg parasitoid species for R. clavatus, two parasitoid species for P. ruralis, and five natural enemy species (including parasite, predator and entomopathogenic fungi) for either S. litura or A. glycines were identified, respectively. Among them two egg parasitoid species, Gryon japonicum and Ooenyrtus nezarae for R. clavatus, for and one parasitoid species for P. ruralis, that belong to Betbylidae, were new to Korea.

This study was conducted to explain degree of injury caused by P. panopealis larva which is the key component to develop economic injury level or control threshold in green perilla and was carried out in polyvinyl houses at Yuseong Daejeon, Geumsan and Yesan Chungnam from 2004 to 2006. Of 5 major pests in green perilla polyvinyl house, P. panopealis larva injured green perilla leaf by 48.5% on average under no insecticides application. The peak occurrence of P. panopealis adult was early August and late September in 2004 and 2005 studies. The feeding amount of P. panopealis larva among 1st to 3rd instar was not different, but from the 4th instar the feeding amount greatly increased and this result was consistent with daily feeding experiment in which the amount greatly increased from seventh day. The degree of injury which was investigated with different larval infestation levels showed that the degree of injury increased a little but was not different significantly as the density increased. The density of P. panopealis larva in damaged green perilla plant was less than three individuals/plant. This result indicates that P. panopealis adult lays egg on green perilla leaf dispersedly and larva hatched from egg injures only the leaf which egg is layed. These preliminary data seems to be very useful to design economic injury level and control threshold studies for P. panopealis in green perilla polyvinyl house.

This study was conducted to identify status of odor managing zones in incheon metropolitan city. There are four odor managing zones in incheon ; Namdong industrial complex, Seobu industrial complex, Seoknam-Wonchangdong industrial complex, Baekseok-Oryudong area. Each zone with 16 sampling sites consisted of three parts. One was inner area (1-1~1-4 site) and another was boundary area (2-1~2-4 site) and the third was outer area (3-1~3-8 site). We analyzed quarterly 18 items of odor pollutants in order to investigate air quality of odor managing zones during 2006. Data of inner area was higher than that of boundary or outer area and concentration of odor pollutants of night was higher than that of day. Overall results of this study showed that concentration of odor pollutants in some sampling sites of boundary and outer area was too low (about ND). Especially ambient hydrogen sulfide of inner area (1-1 site) and boundary area (2-1 site) in baekseok-oryudong odor zone were 0.82 ppm and 0.55 ppm respectively due to landfill gas.

The malodor control law enacted in 2005, regulated malodor substances ansmg from factory or service industry. In this work, an attempt is made to understand the actual conditions of malodor occurrence for types of industry and to settle trouble for a odor complaint. The odor concentration unit (o.u/㎥) of each major odor emitting industry was actualized by the indirect olfactory method including air dilution sensory test method in Korea. The industry that malodor complaint originate mainly were Chemical manufacturing industry, Waste disposal facilities and Livestock farming. As the results, Livestock farming were measured from 3 o.u/㎥ to 30 o.u/㎥ in the source boundary site, Waste disposal facilities were measured from 300 o.u/㎥ to 669 o.u/㎥ in the stack and Chemical manufacturing industry was analyzed from 300 o.u/㎥ to 1442 o.u/㎥ in the stack. Sampling of the source boundary site was demand the reform because malodor state at the field not expressed properly. In oder to solve such problem, propose total odor emission rate (T.O.E.R) introduction.

The state and its proper countermeasures of unreported industrial accidents in Gyungbuk area was investigated throughout a survey research. The goal of the study was to identify major factors that affect the number and causes of unreported accidents. Results from the survey indicated that significant number of unreported accidents exists especially in the small and medium sized industries. Types of the accidents, amount of increase in the insurance cost and level of the governmental enforcement due to the accidents were the major factors for deciding whether to report or not. These results suggested more compromising actions have to be taken by the government for revealing the present but unreported industrial accidents. A more efficient way for preventing the industrial accidents can be considered on the basis of true understanding about real industrial accident statistics.

A bridge is a space used as a passage. This space should be functional, solid, and beautiful. Since the beginning of human life, bridge architecture has given importance to function as a connection from one place to another. Stepping stones in the stream were the connections between divided spaces in the agricultural life, the bridge on the entrances of a town was the place for separation, expectation, and communication for people gathering around the community. Southern Chinese provinces such as Zhejiang, Hunan, Yunnan, and Guizhon is famous for it's spectacular scenary, and tribes like the 'Miao' and 'Dong' live in a cooperate community. The 'Dong' tribe is one of the 'Yue' genealogy where the people have settled down in this place in the days of 'Qin Shi Huang(Qin dynasty)'. As the population of the 'Dong' tribe growed, they used a bridge to connect town to town. The scale became larger with additional design, giving splendid achievement to bridge architecture. The 'Fungyu bridge' in Tongdao and 'Chungyang bridge' in Sanjiang are some fine examples. The Fungyu bridge could be defined as a bridge which blocks wind and rain, this has the same function as the lounge bridge in Taishun located in southern Zhejiang province. In Taishun, 5 minority races such as the 'Dong' and 'Miao' people have been living together as a clan society for centuries on mountains as high as 1000m following their own tradition. The 'Xiliu river' flowing thorough has a variety of bridges remaining in it's original form, and it is recently known as a museum of ancient bridges. The formation of the bridges in Tongdao and Taishun shows that it is different with the arch and straight bridges remaining in Korea. In this study, it is readjusting the base data, showing plan characteristics and describing the construction of the wooden structure above the bridge post.
