Communication network numbers are used in classifying each kind of network, identifying the communication companies and choosing services that are supplied by the companies. In the present, a new numbering system is needed to distinguish a new additional communication network. However the present numbering system of domestic communication network has some problems such as exhaustion of network number, excessive local numbers, and so forth So, in this thesis we call the wire and the wireless telephone network, the pager network and the personal number as communication networks, and consider the present condition and problems of our country, Korea, and foreign countries. Then we propose the efficient numbering plan. Firstly, the present 10 numbering systems that are distributed, such as communication networking number $\ulcorner$01X$\lrcorner$ are diminished into 5 communication network numbers that have same quality. Secondly, subscriber numbers are united to 8 digit and 144 area codes are made into widened 5 area codes. Thirdly, the personal numbering services are cross-distributed by century. And we examine the technical convening plan and the legal converting plan and investigate expecting efficiency of proposed numbering system. If this numbering plan is executed, subscriber's number on communication networks are unified at 8 digits, 5 reserve numbers are secured in exhausted communication network number of $\ulcorner$01X$\lrcorner$, and they can distribute subscriber numbers over twice as much. In addition, number acceptability is enlarged from 237,600 thousands to 400,000 thousands. Personal number can be classified at not only century but also a decade. Accordingly, acceptable numbers are increased two folds enough to provide unification and population increase. We were able to confirm all the efficiencies.

Korean TV program market has started since 1995 along with Cable TV and local TV stations and increased significantly due to Korean wave. Now the new platform such as IPTV makes a new opportunity of growth to the TV program market. This study will analyse the actual status and mechanism of Korean TV program market. To begin, Korean TV market is still dominated by terrestrial TV in domestic distribution market and in exportation even though the windows are diversified. This has influenced not only for the production market but also the distribution market as the following: continuous conflicts between terrestrial TV and independent production companies even though the significant increase of independent production in quantity ; terrestrial TV's dominance in distribution market with enormous libraries as for the major content provider. In addition, there are limited independent distributors due to the exclusive trade of TV programs by terrestrial TV. As for the exportation, foreign market for Korean TV programs are mainly Asian countries like Japan, China, etc. Furthermore, since the genre of distribution has been concentrated in dramas, it is time to make efforts to find a solution. Thus, this research can give a guideline as for the first step.

The present study was designed to observe the oestrus responses in the indigenous ewe induced by cloprostenol sodium manufactured by two different companies ($Ovuprost^{(R)}$, BOMAC, Newzealandand $Prostenol^{(R)}$, Techno, Bangladesh). Twelve local ewes were divided into 3 groups (n= 8). The ewes in Group I and II were induced by intramuscular injection of $100{\mu}g$ (0.4 ml) of cloprostenol sodium ($Ovuprost^{(R)}$ and $Prostenol^{(R)}$), respectively. The $2^{nd}$ injection in each group was given at 9 days apart. The ewes in Group III were kept as control for observing natural oestrus characteristics and comparing the responses with induced oestrus. Hundred and 75% ewes showed oestrus following $2^{nd}$ injection of $Ovuprost^{(R)}$ and $Prostenol^{(R)}$, respectively. The average time of onset of oestrus following $1^{st}$ and $2^{nd}$ injection of $Ovuprost^{(R)}$ and $Prostenol^{(R)}$ were $50.5{\pm}3.5$ vs $48.0{\pm}0.0h$ and $49.9{\pm}1.9$ vs $49.5{\pm}1.7h$, respectively. There was no significant difference between the two types of cloprostenol sodium group on the onset of oestrus. The average duration of oestrus was $27.5{\pm}0.7$ vs $27.5{\pm}0.0h$ and $25.9{\pm}3.3$ vs $24.2{\pm}0.3h$ in $Ovuprost^{(R)}$ and $Prostenol^{(R)}$ treated ewes, respectively. For natural oestrus, the duration of oestrus was $25.2{\pm}3.3h$. There was no significant difference among the cloprostenol sodium produced by two different companies and natural oestrous ewes on the duration of oestrus. The higher percentages of cornified cells were present in induced oestrus (90 and 85%) compared with natural oestrus (80%), although there was no significant difference among them. The pregnancy rates were 75, 66.7 and 100% in $Ovuprost^{(R)}$, $Prostenol^{(R)}$ and natural oestrous ewes, respectively. The above results indicate the suitability of using cloprostenol sodium for synchronization of oestrus in indigenous ewes in Bangladesh.

Femvertising campaigns are more easily observed in oversea rather than in Korea. Most recently, not only global companies but local consumer goods companies launched several femvertising campaigns. However, no research was done on effects of femvertising in Korea. Thus, this study will explore Korean college students' understanding of, attitude toward, and effects of femvertising through focus group interviews. Study results found that college students have low level of understanding on the concept of femvertising. However, they are somewhat familiar with contents of femvertising. Femvertising is believed to have positive impacts on gender equality and female empowerment whereas there are growing concerns over commercializing feminism. Study participants, regardless of gender, suggest that femvertising could influence consumers' attitude toward advertising and brand, but they are skeptical of purchase intention. Lastly, female participants suggest that femvertising, compared to traditional advertising, will enhance attitude toward ads and brand, and even have a positive impact on feminism. However, male participants suggest that femvertising may exacerbate the gender conflict between males and females which is called as 'misandry' or 'misogyny'.

The Korean government has been pursuing many supporting programs to enhance the competition of water transportation companies in recent years. To implement the policies effectively, which needs its monitering and evaluates about their business performance. The purpose of this study was to evaluate the business performance of water transportation company groups and determine the outranking between the groups using the Integrated Fuzzy AHP-PROMETHEE.. To achieve this purpose, first, the companies were classified into seven alternative company groups and the criteria for their evaluation was extracted Second, the weights of the criteria, by maritime and port expert survey, were calculated using the Fuzzy AHP. This paper, finally, determined the total priority orders of their company groups as the link Fuzzy PROMETHEE II with weights of the criteria and the local priority orders between them using the Fuzzy PROMETHEE I. In the proposal for this model, thus was collected four criteria such as growth ability, beneficial ability, technical ability, and productive ability. Through the result of this evaluation, the other marine transportation services group was determined as the highest outranking but the inland passenger & cargo transportation services group was lowest. Thus, the developing plan of the productive ability for the other marine transportation services group should be reviewed to continue its good performance, and all off the criteria for the inland passenger & cargo transportation services group to raise the performance should be reviewed.

Confined spaces are inherently dangerous workplace and many fatal and nonfatal accidents have been reported. Even though these accidents occur in various kinds of confined spaces, there has rarely been reported on the health hazard agent, i.e., the types of gases and their concentration ranges. Therefore in this study, we evaluated several toxic and asphyxiating gas concentrations in various confined spaces. We surveyed 57 manholes, 3 sewage treatment plants, 2 yellow radish manufacturing companies and 7 barges to measure the concentrations of oxygen($O_2$), hydrogen sulfide($H_2S$), carbon monoxide(CO), ammonia($NH_3$). Lower Explosion Limits(LEL) and Volatile Organic Compounds (VOCs). Those four types of confined spaces occupies 56% of accidents during last 9 years in Korea. In 57 manholes, the concentration varied according to the types of manholes; rainfall and sewage, and by location; residential and industrial areas. Sewage manhole in industrial area was evaluated as the most hazardous than other types of manhole like rainfall manholes, residential sewage manholes. The highest $H_2S$ concentration and the lowest $O_2$ concentration at sewage manhole in industrial area were 300 ppm, 8.7% respectively. In 3 sewage treatment plants, $H_2S$ and $NH_3$ concentrations were reached up to the 500 ppm and 200 ppm respectively. Two yellow radish manufacturing companies showed the concentrations of 316 ppm, 505.2 ppm, 90 ppm and 15.7% for $H_2S$, CO, VOCs and $O_2$, respectively. Seven barges showed 15.9%~20.9% oxygen concentration. Gas species and concentration ranges varied by the types and location of confined spaces; CO, $H_2S$, $O_2$ could be hazardous in manhole, especially manhole connected to sewage plants. CO, $H_2S$, LEL, $O_2$, $NH_3$ should be controlled in sludge silo and sluge pumping confined spaces in sewage treatment plant. The activity of lifting out radish from the storage tank was evaluated more hazardous rather than the other activities in yellow radish manufacturing industry. The employers must conduct the survey to identify all possible confined spaces in their local workplace prior to performing the tasks. At the national level to reduce the accidents in the confined spaces, we suggest that systemic approach and active education program including possible hazards, standard operation procedures, ventilation plan, and personal protective equipment in confined spaces should be implemented.

Holding conventions and exhibitions are deemed as a highly valued-added services. The conventions and exhibitions industry (CEI) contributes to the development of the region in which the venues are located by creating jobs, boosting the local economics, attracting dollars and increasing tax incomes. At the same time, the international awareness of the region rises after holding an international exhibition or convention. This study investigated the effects of outsourcing services quality that employed by corporations organizing conventions and exhibitions on business performance and customer satisfaction of organizing corporations. It was found that many convention organizing corporations relied on outsourcing services for the most of the process. Given that the staff members of outsourcing companies serve as the major source of services for events, the quality of their services has much effects on the business results of hiring corporations. In this study, major factors influencing the service quality and the importance of the service quality were addressed. And the ideas for effective method for controlling the outsourcing sources were also suggested for hiring corporations and outsourcing companies.
