  • Unrecorded fern species of Korean flora, Thelypteris interrupta (Willd.) K. Iwats. (Thelypteridaceae) and Dryopteris subexaltata (H. Christ) C. Chr. (Dryopteridaceae), were collected from Jeju island off the south coast of Korean peninsula and reported here. T. interrupta is most similar to T. acuminata (Houtt.) C. V. Morton in morphology, however, the two species are readily distinguishable by the plant color including rhizome, stipe base and spore, and the presence of glandular hair as well as the distribution pattern of sorus on lower leaf surface. D. subexaltata is also well distinguishable from its relatives, D. sparsa (D. Don) Kuntze, D. sabaei (Franch. & Sav.) C. Chr., and D. yakusilvicola Sa. Kurata by the presence of proliferation, shape of pinnae, distribution pattern of sori on lower leaf surface, and shape of indusium.

  • This study conducted tunnel blasting to evaluate the blasting effect of a shear thickening fluid-based blasting stemming material and a sealed plug device under development. STF single stemming and STF stemming materials were combined with plugs to a tunnel blasting to which the SAV-Cut method was applied, and the advanced rate and fragmentation of tunnel blasting muck pile were compared when sand stemming was used. Tunnel advanced rate was evaluated using a 3D laser scanner. When the STF stemming material and STF stemming material with the plug were compared to the sand stemming material, it increased by 5.7 and 5.36%, respectively. As a result of evaluation of the fragmentation of tunnel blasting muck pile, it was the best when the STF stemming material was applied, and it decreased by about 61% compared to the case of sand stemming blasting. However, no significant improvement in blasting effect was observed with the application of plug devices.

  • Korean folk medicine 'Jil-Kyung-Ee' has been used to cure female disease, acute gastritis, edema, abdominal pain and pleurisy. The botanical origin of the crude drug has not been confirmed pharmocognostically. To clarify the botanical origin of 'Jil-Kyung-Ee', the morphological and anatomical characteristics of the leaves and roots of Plantago species growing in Korea, i.e. P. asiatica L., P. camtschatica Cham., P. depressa Willd., P. lanceolata L., P. major L. var. japonica (Fr. et Sav.) Miyabe were compared. As a result, it was determined that 'Jil-Kyung-Ee' was the whole plant body of Plantago asiatica and Plantago camtschatica.

The community of evergreen broad-leaved trees comprised a total of 44 species including Sasa coreana Nakai and camellia japonica L. and the distribution of evergreen broad-leaved trees was good in this island as a whole. Sasa coreana Nakai, Castanopsis cuspidata var. sieboldii Nakai, Ficus erecta Thunb., Ficus nipponica Fr. et Sav, Stauntonia hexaphylla (Thunb.) Decne, Cinnamomum japonicum Sieb., Machilus thunbergii S. et Z., Lozoste lancifolia (S. et Z.) Bl., Ilex intergra Thunb., Camellia japonica Thunb., Hedera rhombea Bean and Ardisia japonica Bl. etc. in this island were autochthonous flora and their preservation is required.

  • The purpose of this paper is to measure the international competitiveness of insurance business and to analyze its determinants empirically. I have attempted to use Revealed Comparative Advantage(RCA) index to measure domestic competitiveness. confining to OECD countries only. Among domestic competitiveness advantage countries in the insurance, there are Austria, Denmark, France. Japan, Korea... etc. The factors of domestic competitiveness determinants were found out through multivariate regression analysis with panel data$(1990{\sim}1995)$. In insurance industry, statistically significant variables are employee's per capita premium of insurance company (Pro), stock market capitalization/GDP(MVESR), saving rate (SAV) and real interest(RMMR), while they are Pro, MVESR, and real interest in Korea insurance industry.

  • Objectives : The purpose of this study was to explore comparison of clinical characteristics among Anxiety disorder, Depressive disorder, and Co-morbid of Anxiety disorder and Depressive disorder. Methods : Since January, 2017 to May, 2019, patients were recruited from the department of psychiatry of Hanyang University Guri Hospital. Participants were diagnosed Anxiety disorder, Depressive disorder, and Co-morbid of Anxiety disorder and Depressive disorder using DSM-5 criteria by board certified psychiatrists or clinical psychologists. And each of participants tested with MMPI-2 and clinical psychologists were converted MMPI-2 to MMPI-2-RF. The data were analyzed using SPSS 18.0. Results : The results indicated EID, RC2, HLP, SAV, and INTR-r were the highest in Co-morbid of Anxiety disorder and Depressive disorder group. And BXD, RC4, JCP, and AGGR-r were the highest in Depressive disorder group. Conclusions : The results indicated that Co-morbid of Anxiety disorder and Depressive disorder group were more severe internalizing dysfunction like lower positive emotion, helplessness, social avoidance and discomfort than single-diagnosed group. Single Depressive disorder group were more serious externalizing dysfunction like anger and aggression than single Anxiety disorder and Co-morbid of Anxiety disorder and Depressive disorder. The implications and limitations were discussed.

  • Objectives : The purpose of this study was to examine psychological characteristics of patients who visited psychiatric clinic for medical certificate for military service using MMPI-2-RF. We compared target group with general psychiatric patients with same age range. Methods : A total of 165 male patients for medical certificate and 154 general psychiatric patients were collected from the Department of Psychiatry of three university hospitals. There were significant differences of age and educational level between two groups. We used independent t-test, ANCOVA, ${\chi}^2$ test to examine differences between two groups. Results : Medical certificate group scored higher on the validity scales, the Higher-Order(H-O) scales, the Restructured Clinical(RC) Scales, the Specific Problems(SP) Scales, and the Personality Psychopathology Five (PSY-5) Scales. Especially, EID, RC7, HLP, SFD, SAV, SHY, DSF, and INTR-r showed significant differences between two groups on all three statistical tests. Conclusions : The present study showed that psychiatric patients who received psychological evaluation for military service have significantly higher emotional distress, helplessness, lower self-confidence, and lower quality of interpersonal relationships. And the difference of validity scales between two groups could be related with psychological burden of compulsory military service in the study sample which causes elevation on scales of infrequent responses. MMPI-2-RF would be helpful instrument to assess these emotional and psychological characteristics.

  • Objectives: The current study aims to develop Korean Social Affective Visual Stimuli (K-SAVS) to arouse social affect. Methods: K-SAVS is composed of pictures of social situations among East Asians. Each picture contains a negative, positive, or neutral affect. Positive and negative stimuli were presented to one group of subjects. Negative and neutral stimuli were presented to another group of subjects. All subjects were required to fill out Affective Valence and Arousal Manikin. Results: In the initial test, 18 positive affective stimuli pictures (1 set) and 36 negative affective stimuli pictures (2 sets) were chosen from 95 stimuli pictures. Positive affective stimuli pictures showed higher valence (p < 0.001) and lower arousal (p < 0.001) than negative affective stimuli pictures. In the confirmatory test, 18 neutral stimuli pictures (1 set) were additionally selected out of the total of 79 pictures of neutral stimuli pictures and the pictures used in the former experiment. Neutral stimuli pictures showed higher valence (p < 0.001) and lower arousal (p < 0.001) than negative affective stimuli pictures. Conclusion: K-SAVS can be a valid and useful tool for inducing specific social affects of Koreans.
