Purpose - This study examines the effects of Dubai oil price and the volatility on the asymmetry of domestic gasoline price adjustment. Additionally, the study investigates the effects of "Altteul" gas-station and tax-cut policies on asymmetry. Design/methodology/approach - Firstly, the study calculates proxies for asymmetry and volatility of each window(every 3-month) by error-correction model and GARCH(1, 1) using daily domestic gas price and Dubai oil price from 2008/04/15 to 2022/12/31. Secondly, the study investigates the effects of the increasing rate of Dubai oil price, volatility, "Altteul" gas-station and tax-cut policies on asymmetry. The autoregressive distributed lag regression model is employed for estimations. Findings - The study finds that changes in the increasing rate of Dubai oil price and both types of volatility of Dubai oil price increase asymmetry. While "Altteul" gas-station and tax-cut policies decrease asymmetry. Additionally, the study fails to find that asymmetry in the Korean gasoline market in the estimation with total observations. Research implications or Originality - An increase in Dubai oil price volatility means an increase in cost uncertainty for gas-station owners. Since cost uncertainty is a kind of financial risk, the increase in volatility reinforces the asymmetry. The study provides supporting evidence for the idea.

This study investigated solutions of not only weak organization but also poor communication with customers from point of view of SNS such as Naver blog, Naver band, Kakao Talk and Facebook to promote local business market. The study gave strategies: First, SNS marketing strategy shall be used to do public relations and communicate in accordance with features of each SNS. Naver Blog that is opened SNS shall be used to do public relations and to invite new customers, and Kakao Talk that is closed SNS shall be used to increase customers having high loyalty, and Facebook that has both properties of SNS, that is to say, openness and closure, shall be used to raise effects of word-of-mouth to make use of new sales window. The communication can find out customers' needs to provide customers with customized services. Second, Naver Band and/or cafe shall be opened to increase link and friendliness and to have community consciousness realizing common goal and to destroy merchants' helplessness and individualism and to make change of the market for the place of community. Changes among the merchants may get better ideas to do events continuously and to get more SNS marketing effects and synergy. Third, the merchants shall make change not momentarily but continuously by making efforts steadily. Good communication in and out of the market may create inherent brand value to differ from super chain and/or SSM and to increase sales as well as traditional market image and to attain customers' loyalty.

Evaluation on the environmental noise is carried out by surveying subjective response of residents with physical measurement of noise during long period in field. Particularly field survey is used to make regulations from the analysis on how many people are annoyed for specific noise level, and laboratory test used to analyze the relationship between physical parameters of noise and subjective responses. In the laboratory controlling the variables is easy but the results could be biased because the condition in room would be different with field. Most of all noise exposure time is considered to be different with real situation, and this study aimed to evaluate the subjective response by exposure time of transportation noise, by applying three kinds of variable how much they give effects on the annoyance as the exposure time is operating condition, windows type and sound level. As a result there was somewhat difference between operating type and annoyance, which is caused by the sound characteristics operated in different condition. However the window type didn't give much effect to the annoyance as much as sound type. This means that the subjective response could give similar result by exposure time even for different window types. Most of all, the main factor affecting subjective response is considered to be the sound level and the exposure time.

In this study, the spatiotemporal surface temperature changes were analyzed in the Korean peninsula. The surface temperature variation was estimated using the split window method and NOAA/AVHRR data in 1991, 1995 and 2000. The ranges of differences in temperature between day time and night time were $3-15^{\circ}C$ around the peninsula. The differences in seasonal variations and yearly fluctuations in big cities were lower than those in rural areas and showed clearly the effects of the urbanization. The characteristics of urban heat affects were further determined based on the day and night time temperature comparison on Busan metropolitan area between these periods. Finally, the future use of this technology was suggested for the urban environmental planning.

The material world around human is normally composed of opaque one, with which human has made the spaces. The opaque material to make space has played a role to control the relationship among people and has produced socio-cultural things since the history started. The opening of opaque material(wall) connects one space with the other. Therefore, the meaning of opening is a connection among people who are in different spaces in terms of sociology. In conjunction with this, socio-cultural situation has been deployed differently. In the traditional european domestic space, the glass has been applied to this opening since they found the glass. It disconnects two spaces physically but connects them visually. Therefore, without blocking the opening visually, the glass became to protect people with their interior space from outside environment. The important thing is that the application of the glass in a building had been restricted because of opening size. However, after Industrial Revolution with the advanced technology of architecture, the glass came to be applied to the building and it became widen. So, the concept of glass window became to be the one of glass wall. This change made a transformation of visual character between two spaces which are separated with glass wall. This means that the glass wall gave two directional visibility while the glass window gave one directional visibility from inside to outside of space. This is because the amount of the natural light to the interior space increased due to widen glass in a space. This gave a change of visual authority and the space of surveillance(interior space) became to the one of communication. The space of surveillance, Michel Foucault mentioned in his book surveillance and punishment, is a very private one that is not visually permeable from the people outside, while the space of communication is a public one which needs other eyes. In the space of publicity, there needs a rationality, morality and ethics because of public surveillance and in the space of privacy, there restores a desire for sex and assaults.

Jeonju is well-known as a native place of traditional Hanji from ancient times because of it's proper weather, soil, and sunlights. Traditional Hanji is selected one of the Traditional Cultural Contents Industries of Jeonju nationally, and can produce synergy effects on gaining competition if we develop traditional Hanji industry into high-technology by relating cultural contents. The purposes of this study was to identify consumer attitudes and behaviors toward traditional Hanji products. The results of this study were as followed: 1. Representative products of Jeonju City were a rice with vegetables, a traditional Hanji, and a Korean-style house, and these results showed a consistancy with Han-Brand products promoted by Ministry of Culture and Tourism. 2. Many consumers experienced of a box, a copy paper, a book or notebook made of Hanji, but less experienced of fashion accessary products. Consumers had higher interests in wall or window paper and copy paper, but had lower interests in fashion accessary products such as necktie, shawl, and folding fan. More consumers intended to use wall or window paper and copy paper, but intended fashion accessary products less. Many kinds of Hanji products were produced and displayed on a Hanji Crafts House, but only few consumers had experiences. 3. Younger generations had higher interests and experiences of Hanji products, and unmarried officiers or full-time house wives had experiences Hanji crafts more. 4. Consumers were interested in daily necessaries or interior products made of Hanji.

There have been several efforts to avoid unnecessary retransmission timeouts (RTOs), which is the main cause for TCP throughput degradation. Unnecessary RTOs can be classified into three groups according to their cause. RTOs due to multiple packet losses in the same window for TCP Reno, the most prevalent TCP version, can be avoided by TCP NewReno or using selective acknowledgement (SACK) option. RTOs occurring when a packet is lost in a window that is not large enough to trigger fast retransmit can be avoided by using the Limited Transmit algorithm. In this Paper, we comparatively analyze these schemes to cope with unnecessary RTOs by numerical analysis and simulations. On the basis of the results in this paper, TCP performance can be quantitatively predicted from the aspect of loss recovery probability. Considering that overall performance of TCP is largely dependent upon the loss recovery performance, the results shown in this paper are of great importance.

The purpose of this study is to dimensionally examine the factors of policy changes by applying the ACMS model to KEPCO's structural reorganization privatization policies and study its implications. As a result of the analysis, among the external variables that affect as a financial source or restriction to advocates, all areas except for the difference in opinion of the people as well as policy decision and effects of other subordinate systems were shown to be in an advantageous condition acting as a financial source to advocates of structural reorganization privatization. On the other hand, advocates affected by the external variables share a certain belief system in which the advocates of privatization share the justification of profitability while the advocates of collectivization share the justification of publicness. In these flows, the announcement of the privatization plan of public enterprises of the committee of planning and budgeting acts as a matter of contact which opens the windows for policy changes, and this window goes through ignition, explosion, and fixation which causes fierce interactions among advocates of both sides. Eventually, in accordance with the contents of excluding electricity(KEPCO) from the list for privatization the window for policy changes has closed and things have changed to a transitional KEPCO privatization policy. Based on this, the first implication is that non-official participants such as the people, social organizations, labor unions, etc. influence policy changes more than they did before. Secondly, in the process of policy changes, there is an order of boundary even in the fierce interactions between each advocate. Thirdly, specific variables can play various roles in complex policy phenomenon. Fourthly, a logical analysis using the ACMS model is possible in Korea as well. Fifthly, as a result of analyzing the change process of the KEPCO structural reorganization privatization policy through the ACMS model, not all matched with the main research results implied by the ACMS model.

For the fabrication of a multilevel resist (MLR) based on a very thin amorphous carbon (a-C) layer an $Si_{3}N_{4}$ hard-mask layer, the selective etching of the $Si_{3}N_{4}$ layer using physical-vapor-deposited (PVD) a-C mask was investigated in a dual-frequency superimposed capacitively coupled plasma etcher by varying the following process parameters in $CH_{2}F_{2}/H_{2}/Ar$ plasmas : HF/LF powr ratio ($P_{HF}/P_{LF}$), and $CH_{2}F_{2}$ and $H_2$ flow rates. It was found that infinitely high etch selectivities of the $Si_{3}N_{4}$ layers to the PVD a-C on both the blanket and patterned wafers could be obtained for certain gas flow conditions. The $H_2$ and $CH_{2}F_{2}$ flow ratio was found to play a critical role in determining the process window for infinite $Si_{3}N_{4}$/PVDa-C etch selectivity, due to the change in the degree of polymerization. Etching of ArF PR/BARC/$SiO_x$/PVDa-C/$Si_{3}N_{4}$ MLR structure supported the possibility of using a very thin PVD a-C layer as an etch-mask layer for the $Si_{3}N_{4}$ layer.
