This study estimated the size of ornamental fish market as the basis survey for the development of the ornamental fish industry in Korea. It presents improvement projects agendas for the development of the Korean ornamental fish industry by investigating the challenges of the ornamental fish industry and consumer awareness. First, looking at the size of the ornamental fish market, calculated on the basis of survey results, the size of ornamental fish market is analysed as 231.8 billion won. The actual ornamental fish market is presumed to be much larger than this considering unclear gross sales from e-commerce and group sales, goods excluded from the ornamental fish export, expensive ornamental fish transaction from smuggling are missing. Ornamental fish industry and consumer awareness survey results can be described as follows: First, revenue structure of the ornamental fish market depends on a handful of expensive purchasing group rather than on low-cost consumption group. Second, many members of the ornamental fish producers, wholesalers, road shops are small-scale. Third, the sale of aquarium fish and aquarium fish related supplies in road shop have different market structures. Fourth, ornamental fish consumption is in the ongoing recession. Fifth, ornamental fish industry hopes for expansion of distribution and Research & Development. Sixth, satisfaction of ornamental fish consumers is generally low. As described above, ornamental fish industry in Korea are vulnerable in the market structure and industry is small and the consumer's satisfaction degree is staying in the 'normal' level. If current state will continue, future consumption can be reduced. It is necessary to increase the competitiveness by using various method including reorganization of the structure of the ornamental fish industry even though it is hard to reach conclusion only with the results of the survey.

Uiseong subbasin belonging to Kyungsang basin resulted from volcanic activity in the late Cretaceous. In this study, we carry out MT and gravity survey at the Hwasan caldera, which was formed of volcanic and abyssal rocks complex, then analyze and identify geological substructure. Potential survey such as gravity and magnetic survey has been mainly carried out in former studies, so depth information for understanding substructure was not enough. To complement a potential survey, we use MT method, which has high vertical resolution. Moreover we make a simple 2D model comparing with former study. The result of MT and gravity 2D modeling shows that this area is roughly composed of 3 layers; The bottom layer is a basement. In the second layer, intrusive rocks having high resistivity is placed along the ring faults and the sedimentary layer of low resistivity is inside caldera. The highest layer is alluvium. To comprehend the 3D structure of the Hwasan caldera, we perform 3D gravity inversion, and construct the 3D model from the result of 3D gravity inversion. MT responses are calculated by using the constructed 3D model and the 3D model of the Hwasan caldera's structure is suggested after comparing the calculated values with the observed values at MT line.

Though an internet survey, an alternative method for the off-line survey, has various merits is, it still has some problems such as sampling bias and low reliability from insincerity during survey. Especially the exogenous variables such as sample respondents of the environment should be controlled to make internet survey trustworthy. This study attempts to design and implement such system that can help researchers to control the network and sampling environment and behaviors on respondents. Thru the various Question forms and structured Questionnaire design, this study tries to contribute the improvement of survey satisfaction and the reliability for survey result in internet survey system.

The aim of this study is to find out the pattern of Ger form, inner spatial composition of Mongolian Ger house, and to take a dig at the structural or symbolic elements of nomadic architecture of Ger. To the point of view of corresponding to living and space of housing, remarkable characteristics of Ger Architecture is able to pull down and recombine the structures of nomadic house. Even though urbanization of Mongolia has spreading rapidly in a whole nation, most of people preserves traditional housing pattern within Ger. The ways of survey are to study of traditional home of Mongolia, and then field work at residence or mountain area in Ulan Bator and Gorkhi Terelj National Park area. This survey contains the form, size, structure, spatial composition of living space, structure, and materials. There are three results as follows: First, the form of Ger house is like a pyramidal or crown roof style to approximate to the round shape of it. Usually they had lived in nomadic way of life, so the Ger had a movable and flexible structure. Second, the Ger is easy to build up and deconstruct to move or find a new pasture. Third, the Mongolian Ger structure is composed by mainly five elements that are Khana, Khaalga, Toono, Bagana, and Uni. It has a hierarchy of internal spaces which are classified to gender, orientation, and property.

Purpose - The purpose of this study is to investigate the role of Teamwork on Engagement among employees of private primary and secondary schools in Plateau State, Nigeria using the dimensions of Teamwork, which are Communication, Leadership, Team Structure, Situation Monitoring, and Mutual Support on Employee Engagement. Research design, data, and methodology - To analyze the relationship among the variables, the study adopted the descriptive and explanatory research design, and a cross-sectional survey method using a survey questionnaire containing 29 items, with a 5-point Likert scale. The samples of 274 employees (both academic and non-academic) were selected using a simple random probability sampling technique. Multiple Regression was used to analyze data with the aid of the statistical package for social sciences (SPSS version 23.0). Result - This shows that Communication, Leadership, and Situation Monitoring have a positive and significant relationship on Employee Engagement, while Team Structure and Mutual Support show a negative direction but still maintained a significant relationship. Conclusion - The management of private primary and secondary schools should pay attention to Communication, Leadership, Team Structure, Situation Monitoring, and Mutual Support among their employees to promote Employee Engagement in the workplace. It also recommends that future studies should be carried out in other sectors.

In urban area, urban forests work as an ecological center that mitigates the environmental pollution of the area. In order to maintain the ecological function of a forest, the management method should be established based on ht through investigation of the vegetation structure of the forest. In this study, the vegetation structure of Namsan in Kyungju area was investigated in order to study the ecological value of Namsan and to suggest a desirable management alternative. 21 plots were selected as survey areas. Using the TWINSPAN technique, the forest of Namsan was classified into four communities: Quercus serrata community(I), Castanea crenata-Q. serrata-Q. mongolica community(II), Pinus densiflora community(III) and P. densiflora-P. rigida-Robinia pseudoacacia community(IV). The survey results were summarized by five: 1) the distribution of vegetation showed 2) P. densiflora was the absolutely dominant species in Namsan, 3) number of the average species was 12.6$^{\circ}$$\pm$3.1, 4) number of individual was 131.1$^{\circ}$$\pm$47.8 per a plot(100$m^2$), 5) the results of annual ring analysis revealed that the age of P. densiflora in Namsan was about 3 0$^{\circ}$~60$^{\circ}$years old. From the above results, it was found out that the forest has two problems. One thing is maintenance of P.densiflora against succession, another is artificial forest dispersion. The problems of Namsan forest management will be solved with further studies related.

Recently, electrical resistivity survey is used in the various fields and applied to urban area with many electrical noises. Therefor it's necessary to observe the electrical noise effect of the geological structure. The physical scale modeling was conducted for measuring the electric noise effect of the two geological models at various distances, depths and diameters of the electric noise objects. The results are as following. 1. When conductive noise object was vertical to the strike of geological structure and moved to the strike direction, the effect of conductive noise object at various separated distances to the measurement line was disappeared at a half distance measurement line length regardless of electrode arrays. 2. When conductive noise object was vertical to the strike of geological structure and moved to the strike direction, the effect of conductive noise object at various depths was disappeared at 4unit apart from the measurement line regardless of electrode arrays. 3. When conductive noise object was vertical to the strike of geological structure and moved to the strike direction, the effect of conductive noise object at various diameters was disappeared at 4unit apart from the measurement line regardless of electrode arrays.
