An insect faunal survey was carried out to investigate insect community structure along the vegetation community to monitor insect species in forest ecosystem. We performed day and night collections from June to August along three vegetation communities of Is. Nam-hae in 2014: the first stand with Pinus thunbergii, the second P. thunbergii with Quercus serrata and the third P. thunbergii with various Quercus species. In total 2,259 individuals of 532 species, 99 families, 13 orders are identified. Cluster Analyses (CA) showed that all three vegetation communities were relatively similar between vegetation community types. According to indicator species analysis (ISA) result, nine significant indicator species were identified (p < 0.05); five species were found to be affected by the vegetation cluster and four species the month cluster.

In this work, the onset of failure induced by severe strain at elevated temperature was numerically estimated with crossformedempirical hardening law describing material softening. The hardening law can replicate the rate-sensitive behaviorof aluminum alloy 7075 sheets (thickness of 2.0 mm) with initial hardening and progressive material deterioration causedby dynamic recrystallization, dynamic recovery, and micro-void development. The characterized material was applied to thetwo-step hybrid forming process consisting of a drawing at 400 °C followed by a pneumatic forming at 470 °C to produce ashock absorber housing with an extremely complex shape. The user-defined subroutine codes, VUMAT (ABAQUS/Explicit)and UMAT (ABAQUS/Standard), were sequentially utilized for the drawing and the pneumatic forming, respectively. Theidentified hardening parameters based on uniaxial tensile tests were validated by simulating the two-step hybrid formingprocess and compared with the conventional Voce type law (converging function) and the combined Swift-Voce type law(ever-increasing function) since they play a key role in accurately predicting the onset of failure induced by severe strainlocalization. Finally, simulation results are reasonably well matched with experiments in terms of the moment of failureoccurrence, failure location, final blank shape, and thickness distribution.

구종남 대한언어학회 1999 언어학 Vol.7 No.1

Koo, Jong-Nam. 1999. On the Connective Endings '-ilk'εmi', '-ingεmi' in some Dialects. Linguistics, 7-1, 243-265. This paper aims to explore the morphological structures and the meanings of '-ilk'εmi' and '-ingεmi' which are used as connective endings in dialects. By some morphological, syntactic and semantic evidences this paper concludes that '-ilk'εmi', '-ingε mi' had been made by '-ilk'a(interrogative ending) + ha(auxiliary verb) + m(nominalizer) + c(postposition)' and '-inga(interrogative ending) + ha(auxiliary verb) + m(nominalizer) + ε(postposition)' structure respectively, through fusion. And it was revealed that '-llk'εmi' has the meaning of 'connective doubtful reason' and '-ingεmi' has the meaning of 'doubtful reason'. (Chonbuk University)

This study is for the purpose of examining effects related to duty stress & duty satisfaction due to Police of officers' Physical exercise participation, helping more efficient duty Performance, and positive self-formation. Furthermore, providing basic data that can be helpful to the improvement of police duty. The objects of the study were police officers who were taking part in education program in Police Comprehensive Academy, and the number of police officers who answered the questionnaire is 356 police officers, but data used for real analyzation consist of 300 police officers. The tools for the study were based on Ivancevich's duty stress model in order to measure stress. And also questionnaire used on Kim yoon hee, Kim mae ja, Jo kyung soon, Lee hart kyung's study was used as a complementary tool. The instrument for measuring duty satisfaction rate was developed by Paula. And I used the instrument based on questionnaire that was used by Ko hee soon, Park ki hyung, Kim bum sik, Lee jong kil, Lim bun jang, Jo young chang, Hackeman, Lawlar and Oldham's study. Data analysis is Processed statistically with SPSS/PC+, I Performed T-verification, ANOVA-verification in accordance with the purpose of study after getting the percentage and the real number in case of general characteristics of the objects, and examine an average and standard variation in case of duty satisfaction and duty stress rate. And I set an err rate to 0.5. I verificated co-relation between stress and duty satisfaction with Pearson Correlation Coefficient. The result of the study is as follows, The first, among sociological characteristic and external factor of duty satisfaction, The married is more significant statistically(p< .01, p<.05) compared to the unmarried in terms of compensation system and working condition , which are subfactor of duty satisfaction . In terms of the length of one's service, the longer service term one has the higher significance level one shows in compensation system, working condition, safety, and external factor which are sub-factors of duty satisfaction In terms of an academic background, one who graduated from a high school shows significance statistically only in working condition which is a subfactor of duty satisfaction compared to other people (p<0.5) The second, among sociological characteristic and internal factor of duty satisfaction, the married is more significant statistically(P<.05) compared to the unmarried in terms of achievement which is a subfactor of duty satisfaction. In terms of age the older one shows higher significance level in stability which is a subfactor of duty satisfaction compared to younker one(p<.05) In terms of the length of one's service the longer service term one has ,the higher significance level one shows(p<.01, p<.05). The third, in terms of duty stress due to sociological variable, the married is more significant statistically(p<.05) in case of stress stems from police duty than the unmarried Interms of age, welfare and duty stress are significant statistically(P<.05) Interms of the length of one's service, police's work is significant statistically(P<.05). One who graduated from junior college is significant statistically in police's work, welfare, stress and gets a lot of stress in personal relations(p<.05). The forth, groups participating in exercise are more significant statistically in stability(p<.001), feeling of stability(P<.001), achievement(p<.001), internal factor(p<.01), external factor(p<.05) than croups not Participating in exercise. The fifth, groups participating in exercise are more significant statistically only in personal management than groups not participating in. The sixth co-relation between duty satisfaction and duty stress is r=-0.3814, (P<.001) ,which shows opposite co-relation. so, a result the more stress one has, the lower duty satisfaction he gets.

Koo, Jong-Nam. 1999. On the Discourse 'eodi'. Linguistics 7-3, 217-234. This paper aims to examine the characteristics of 'eodi'(where) and discuss the grammaticalizational principle and discourse functions of 'eodi' in korean. 'Eodi' is used as a interrogative and indefinite pronoun originally. But it is used as a discourse marker. There exist 8 evidences that 'eodi' is used as a discourse marker. This paper argued that 'eodi' had been grammaticalized as a discourse marker through the conext-induced reinterpretation in discourse. And 10 discourse functions of 'eodi' were discussed.

싶다' 구문의 격과 부가어 : HPSG의 확대 논항 구조적 분석 An Extended Argument Structure Analysis in HPSG

최종주,이남근 대한언어학회 2000 언어학 Vol.8 No.1

Choe, Jong-Joo and Lee, Nam-Geun. 2000. Case and Adjunct in the Siphta Construction: An Extended Argument Structure Analysis in HPSG. Linguistics 8-1, 133-152. The siphta construction in Korean shows some intriguing properties such as the case alternation in the complement NP of the lower verb and the optional - but not arbitrary - case marking on the adjunct. We will show that the 'argument structure' alone is not enough to deal with the case marking on the adjunct simply because the adjunct cannot be contained in the argument structure. Therefore, in the framework of Head-driven Phrase Structure Grammar (HPSG for short), we will take advantage of the new feature DEPS (or dependendy structure) proposed by Bouma, Malouf and Sag (1999). The extended argument structure DEPS will enable us, with the help of Case Principle and the notion of structural/lexical case, to take care of the case alternation and case marking on the adjunct in the siphta construction.

It has been hypothesized that jobs that have both high psychological demands and low decision latitude("job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome(MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model(16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects(n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-stain group, and OR of musculo skeletal disorder was 2.446(95% C. I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.
