Differential absorption LIDAR (DIAL) is frequently used for atmospheric gas monitoring to detect impurities such as nitrogen dioxide, sulfur dioxide, iodine, and ozone. However, large differences in the on- and off-line laser wavelengths can cause serious errors owing to differential aerosol scattering. To resolve this problem, we have developed a new DIAL system for iodine vapor measurements in particular. The suggested DIAL system uses only one laser under seeded and unseeded conditions. To check the detection-sensitivity and error effects, we compared the results from a system using two seeded lasers with those from a system using a seeded and an unseeded laser. We demonstrate that the iodine concentration sensitivity of our system is improved in comparison to the conventional two seeded or two unseeded laser combinations.

Phytophthora species, classified under Oomycota, cause significant damage to various crops and trees. The present study introduced Phytophthora species, P. nagaii and P. tentaculata, new to Korea, which pose notable risks to their respective host plants. Our research provided a comprehensive description of these species taking into account their cultural features, morphological characteristics, and molecular phylogenetic analysis using the internal transcribed spacer rDNA region and cytochrome c oxidase subunit mtDNA genes (cox1 and cox2) sequences. In addition, this study first evaluated the sensitivity of P. nagaii and P. tentaculata to five anti-oomycete fungicides, finding both species most responsive to picarbutrazox and P. tentaculata resistant to fluazinam. The data can guide targeted treatment strategies and offer insights into effective control methods. The findings expand our understanding of the diversity, distribution, and management of Phytophthora species in Korea.

This paper aims to investigate a dynamic mechanism underlying the process of knowledge creation and growth with a focus on the 'knowledge-friendly culture' conceptually coined by Davenport and Prusak in 2000. To achieve this objective, key attributes of knowledge are first identified by exploring the generic characteristics and information and interpreting the definitions of knowledge, from which four modes of knowledge growth (Socialization, Externalization, Combination, Internalization) are delineated into a dynamic SECI model by identifying cultural attributes underlying each mode and modeling their casual relationships based on the systems thinking. Further, a series of sensitivity analysis through computer simulation were made to find how 'knowledge-friendly' cultural factors affect the knowledge growth. It is found that individual knowledge is most influenced by organization's cohesion whereas organizational knowledge is most affected by the openness of organization.

Many global business failures have been ascribed to a lack of intercultural competence, especially to a lack of an adequate conceptualization and definition of intercultural competence, focusing instead on the knowledge, skills, and attributes that appear to be its antecedents. Intercultural competence should be perceived as multifaceted important components of global management capabilities. Depending on the related concepts of intercultural competence, such as global mindset, intercultural sensitivity, and cultural intelligence, dynamic aspects of intercultural competence as learning process are suggested. Also, the domain of intercultural competence in the context of global management or business comprised three dimensions - perception management, relationship management, and self management. Each dimension is characterized by facets that further delineate aspects of intercultural competence. With respect to the domain of intercultural competence, appropriateintercultural training methods should be designed. In practice, human resource managers may benefit from gaining knowledge about which measures to use for identifying employee's weakness in intercultural competence in order to create appropriate training programs.

Cobweb disease symptoms were observed in a mushroom farm in Buye, Korea during a disease survey in 2008-2011. Five isolates of Cladobotryum sp. were obtained from the infected caps and stipes. These isolates of Cladobotryum sp. were identified as C. mycophilum based on their morphological, cultural characteristics and analysis of the ITS sequences. Early symptoms were noticed as round, fleshy, yellowish brown lesions on mushroom caps. Late symptoms progressed when the parasitic fungus formed white cobweb circular colonies on dead or damaged pinheads, spread on the surface of the casing, and covered entirely fruiting bodies. Optimal temperature and pH for mycelial growth on MEA is $23^{\circ}C$ and 6.0. Microscopically the spores of the fungus are large and most 2~3 celled produced on vertically branched conidiophores. Mushroom caps turned dark brown and shrunk due to soft rot. Testing of sensitivity to selected fungicides showed that isolate was highly resistance to Mancozeb and Thiophanate-methyl, moderately sensitivity to Iprodione, and highly sensitivity to Benomyl, Prochloraz-Mn and Carbendazim.

The purpose of this study was to investigate and compare the multicultural perceptions (multicultural acceptability, multicultural sensitivity and judging multicultural children) of elementary school students. The subjects comprised 1,252 students (583 third graders and 669 sixth graders), promoted from 20 elementary school in J province. The findings are as follows. First, the independent t-test showed that the lower graders had higher scores in cultural openness and national identity of multicultural acceptability, as well as the cognitive element of multicultural sensitivity than upper graders. In addition, the upper graders had higher scores in unilateral expectations for assimilation of multicultural acceptability, as well as the cognitive element of judging multicultural children. Second, all subscales were found to be interrelated, except for unilateral expectations for assimilation and two subscales (cognitive and righteous) in judging multicultural children. These results imply that in order to help have more positive perceptions of multiculturalism, it is necessary to develop more diverse multicultural education programs for elementary school students which take into consideration their grade levels.

In domestic construction site, convenient facilities for worker are much lacking up to now. These things exert negative influences in the occurrence of construction disaster because a safety-aware of worker-self is been lacking ultimately, and 3D(Dirty Dangerous Difficult) evasion phenomenon for construction site spreads more to workers and actuality that is going through manpower problems may be heavier. This research applied sensitivity safety cultural institutions that make aware of worker's sensitivity in spot to search solution way of these problems from resource of human original nature. By the result, there were affirmative sides that sensitivity safety cultures facilities make created a safety-aware during work to worker-self. Also, these facilities gave as member of a constituent by workers, it examined that become many helps in operation efficiency.

The aim of this study is to define the concept of the matchless, and its social and cultural origins. I shall also define the different types of Matchless style, the respective characteristics of each style, and the distinguishing features of this style in domestic street fashion. In order to do this, 1 have referred to several published studies and a number of Web-sites of Korean fashion information companies for my research. The results of this study are the following; 1. The concept of matchless is a positive way of self-expression by coordination, created by consumers who attach great importance to their image and to developing their individual style. Also, this concept constitutes a new approach to code which reanalyzes existing styles with a new sensitivity. 2. The social & cultural origins of matchless are the expansion of fear of war and terror, and economic depression, the extension of the 5-day workweek, interest in 'Well-being', and the phenomena of cultural diversity. 3. The types of Matchless are Style Matchless, Theme Matchless, Texture Matchless, Season Matchless, and Complex-Layered Matchless. 4. The distinguishing features of Matchless in street fashion are the distinction of formal & Casual wear's Matchless, the creation of a new Look in Sports & Casual wear's Matchless, the development of a new coordinated, layered look, the immense popularity of Denim, the new fashionable versions of Military style, and the renaissance of the Romantic Feminine Look.

The purpose of this study was to investigate the relation between perception of family environment and mental health of boy's high school students. In order to obtain the appropriate data, a questionnaire was administered to 240 boy's high school 2nd-grade students in Pohang city from March 19 to March 28, 1992. The instruments used for this study were Moos's Family Environment Scale Form R and Kim's Symptom Check List-90. The conclusions were as follows : The level of perception of family environment was lower than mean score. Cohesion, achievement orientation, independence, organization, expressiveness were percepted high but active-recreational orientation, intellectual-cultural orientation were percepted low. Mental health of most respondents was well. The scores of obsessive-compulsive reaction and interpersonal sensitivity were high, the scores of somatization and phobia were low. General characteristic variables significantly related to the level of perception about family environment were father's occupation and mother's education level. There were no significant differences between general characteristic variables and mental health. There were mostly negative correlations between perception of family environment and mental health. Cohesion, expressiveness, independence, intellectual-cultural orientation, active-recerational orientation, moral-religious emphasis, organization were negatively correlated but conflict, achivement orientation, control were positively correlated. Cohesion, expressiveness, conflict, achivement orientation, active-recretional orientation, organization, control were significantly related, but independence intellectual-cultural orientation, moral-religious emphasis were no significant correlation.
