As the importance of interface became emphasized recently, function of icon as an element that helps operation and formative function as an aesthetic element are becoming emphasized. Specially, various research methodologies for measuring the understanding degree of users are being attempted in functional aspect, however, they are facing limitations as user evaluation method of quantitative investigation for statistical analysis became overly dependent on the consent from majority. To overcome such limitation, a methodology of measuring sensibility as aesthetic impression or individuality based on the system of emotion or system of understanding of users and designing icon based on the measurement is being attempted continuously. Therefore, this study suggested an evaluation method using reminding words and conducted an empirical study to apply results on the icon design by applying the evaluation method on icon design of printing products to measure the user sensibility and understanding level. Through this process, this study intended to research summaries on the design evaluation method which based on the evaluation of user sensibility and understanding level and to debate effective design methodologies through the process of applying these summaries on the project. The intention was to progress discussion from practical application perspectives apart from the textbook type discussion by applying a research methodology through concrete cases. This study objectified sensibility and understanding level of users in the icon design aspect, suggested a methodology that can be applied on the design, and it is expected to be used when progressing the icon and GUI design.

Objectives : The objective of this study is the Basic research for mind and body cure protocol construction through the Sim(心) study at Buddhism Medicine, Constitutional Medicine, and Oriental Medicine. Methods : 1. The Sim(心) in Buddhism is a target of spiritual culture and subjective awareness of An ascetic person in interior psychology. In this research, the Sim(心) has been modified within a concept of Early Buddhism and You-sic in order to have medical logicality. 2. Since the study deep into Sim(心) within Confucianism has various aspects, each Confucian's theory argument or era. We limited the significance of the Sim(心) to be associated with the category of the Sim(心) in Sasang Constitutional Medicine which is a product of practical Confucianism. 3. The criteria of debate for the Sim(心) is based on the "Hwang-je-nae-gyoung", because "Hwang-je-nae-gyoung" is founded to definite the term regarding spirit or mind in Oriental medicine Results : 1. "Hwang-je-nae-gyoung" which came from thought of You-Sic, thought of Taoism, and Early Buddhism becomes the theoretical basis for the Sim(心) in Buddhism Medicine, Sasang Constitutional Medicine, and Oriental Medicine. 2. The Sim(心) in the mind psychology of Buddhism Medicine, Sasang Constitutional Medicine, and Oriental Medicine has active aspects. but the visual thing // There are visual aspects being contrasted with 'Sim(心)' of mind psychology and aspects of activity in Buddhism medicine, Sasang constitutional Medicine and Oriental Medicine; which are 'Hrd', 'Hrdaya', 'four-large' 'five base', 'chin, chest, navel and abdomen', 'head, shoulder, waist and buttocks' consisting 'the body', and the heart and 'four interorgans' from the study of symbolical interorgans). In Buddhism Medicine, Sim(心)'s Epistemology is the most extensively understood fact about 'Sim(心)', and for Sasang Constitutional Medicine and Oriental Medicine. 'Sim(心)' is limited as an 'Element' that comprises the body. 3. The Functional area of the Sim(心) in the Buddhism Medicine, Sasang Constitutional Medicine, Oriental Medicine is composed with 'consciousness(意識)' 'manas-vij_na(末那識)', '_aya-vij_na(阿賴耶識)', 'mind greed(心欲)', 'Li(理)' and 'Sin(神)', about the interpretive area of 'Sim(心)', 'Sin(神)' of Oriental medicine is the most comprehensive concept, and on the side of the depth of 'thinking' and 'consciousness', '_aya-vij_na(阿賴耶識)' from Buddhism Medicine in the key point. 4. The Sim(心) in the Buddhism Medicine, Sasang Constitutional Medicine, has the positive and negative aspects, such as the 'Dukkha(煩惱)' and A merciful heart or Human Sim(心) and Taoism Sim(心).

The purpose of this review is to discuss the debate concerning the interpretation of epidemiologic studies on particles and health effects. Study of the 1952 air pollution disaster in London established that very high levels of particulate-based smog can cause dramatic increases in daily mortality. However, recent epidemiologic studies have reported statistically significant health effects and mortality due to low levels of air pollution. The statistical significance does not prove causation in observational studies; therefore it is necessary to evaluate these associations. There are arguments for and against each of the numerous studies using Hill's criteria, however the body of accepted evidence supports the causal association. In particular, a high level of consistency in the estimated effect of PM10 has been observed across studies worldwide. The mechanism of the relationship between air pollution and health effects is not obvious. The mechanism of particle-induced injury may involve the production of an inflammatory response by the particulate. The harvesting and the threshold effect are also major concerns regarding the health effects of air pollution. However, current epidemiologic findings indicate that linear models lacking a threshold are appropriate for assessing the effect of particulate air pollution on daily mortality even at current levels.

In online communities, a large number of participants can exchange their opinion using replies without time and space restrictions. While the online space provides quick and free communication, it also easily triggers unnecessary quarrels and conflicts. The network established on the discussion participants is an important cue to analyze the confrontation and predict serious disputes. In this paper, we present a quantitative measure for polarity observed on the discussion network built from reply exchanges in online communities. The proposed method uses the comment exchange information to establish the user interaction network graph, computes its maximum spanning tree, and then performs vertex coloring to assign two colors to each node in order to divide the discussion participants into two subsets. Using the proportion of the comment exchanges across the partitioned user subsets, we compute the polarity measure, and quantify how discussion participants are bipolarized. Using experimental results, we demonstrate the effectiveness of our method for detecting polarization and show participants of a specific discussion subject tend to be divided into two camps when they debate.

A crude oil leakage from a large atmospheric storage tank occurred on 4 April 2014 at 14:50 in Ulsan City, while storing the crude oil in the tank. Emergency Rescue Control Group was deployed in the scene. The company, Fire Service Headquarters and associated agencies got together in Command Post (CP) for discussing an effective corresponding strategy. Many solution plans were drafted in the debate such as power down, stopping the facilities, checking the density of inflammable gas, suppressing oil evaporation, moving the leaked crude oil to a nearby tank and a processing plant and avoiding marine pollution. All the solutions were carried out in cooperation with several agencies and partners. The oil leakage accident was successfully settled up within the process of responding, The Fire Service Headquarters and the company thought that the most important thing was the suppression of oil evaporation and the elimination of ignition source. With Fire Service Headquarters and several agencies' every effort, an explosion and a fire didn't occurred in the scene. This study suggest the improvement of the operating system in Emergency Rescue Control Group in case of petroleum leakage, explosion and fire accidents of atmospheric storage tank, different from a ordinary disaster. Assuming that petroleum leakage in atmospheric storage tank develop the explosion and fire accidents, the spreading speed of the flame and the burning time was experimented and compared with each other. Furthermore, this study concentrates on the effective field response plan prepared for the afterward explosion and fire accidents from petroleum leak in a storage tank, with the database experimented and analyzed in accordance with the angle of radiation in the foam nozzle and the pressure of pumping in a fire engine.

In the context of knowledge sharing, network position has been a controversial subject. A central position in the network provides access to non-redundant knowledge, leading to more opportunities of knowledge sharing. On the other hand, as "bridging" relationships, its characteristics as a "weak tie" suggest innate lack of trust and reciprocity which is considered an impediment to share knowledge. This paper attempts to enlighten the underlying dynamic by examining the interaction between network centrality, motivation and ability in knowledge sharing. Furthermore, this paper examines the concept of knowledge sharing ability in depth by operationalizing the construct into three aspects: extensive and diverse knowledge, social media utilization ability and self-efficacy. The results show a partially supported three-way interaction, where the highest level of knowledge provision is reported when the employee has low network centrality, high autonomous motivation and high knowledge sharing ability, i.e. extensive and diverse prior knowledge. Though all models indicate strong associations between network centrality and knowledge sharing, this suggests an even greater power of motivation and ability that gives the strength to overcome unfavorable environments of peripheral position. Therefore, this paper offers an alternative explanation to the existing debate whether network centrality positively or negatively influences knowledge sharing.

Total fertility rate (TFR) increased from the lowest 1.08 in 2005 to 1.13 in 2006, and a debate is made whether the increase is temporary or continuous as a result of various pro-natal policies. This study intends to explore policy implications revealed in recent fertility change using vital statistics. For this purpose, tempo-adjusted fertility rate by birth order, fertility rate by age of mother and birth order, age-specific fertility for married, and age-specific divorce rate for married are analyzed. The increase of TFR and births for 2006 is largely due to increase of first births at early thirties with slowdown of delayed first marriage and first child birth. The increase of female population (the third wave effect of baby boom) and first marriages of late twenties in 2006 and 2007 would lead to increase of fertility during 2007-2008. But further increase is uncertain because of the decrease trend of marital fertility and increase trend of never-married for twenties. TFRs for first and second births reduced rapidly, while TFRs for third and above births showed no changes, and second births were largely affected by tempo adjustment of fertility. Thus, constructing social environment for first and second births is more effective and necessary than encouraging third births. In addition, social responsibility of child care, child-women health issues due to delayed births, and the need for multi-cultural family support system are discussed.

The primary utilization of recently improved (U-Th)/He thermochronometry is to reveal the low-T thermal histories of shallow crustal sections or transient episodes (such as wildfires or meteorite impacts) because of the high sensitivity of He diffusion to temperature in host minerals. In this contribution, we present reviews and perspectives regarding how this method can be used to characterize the ejection-related shock metamorphism of Martian meteorites. The temperature conditions of shock metamorphism can be constrained through shock recovery experiments, paleomagnetism, and $^{40}Ar/^{39}Ar$ and (U-Th)/He dating. The most reliable constraints can be deduced when these independent approaches are combined. However, the thermal history of the ALH84001 Martian meteorite has been under serious debate because the different methods have yielded contrasting results. Recent work has shown how single-grain (U-Th)/He and $^{40}Ar/^{39}Ar$ dating, two noble-gas based thermochronometries with different T sensitivities, can be used to resolve this issue, providing a good example for future research on other meteorites.

Purpose: This study was conducted to study the attitude of Korean lawyers toward withdrawal of life sustaining treatment, and compare and analyze different types of their attitudes. Methods: Research design of this project was Q methodology approach. The study population was 24 lawyers, aged from 32 to 69 years. Q sample to investigate the attitude of the lawyers toward withdrawal of life sustaining treatment included 34 statements obtained from literatures, TV debate, and depth interviews of 5 lawyers among the lawyers included. After listening to the purpose and method of the study, the 24 lawyers agreed to fill out a survey asking sociodemographic information, and the information was distributed in 9 scale Q-sample. Results: The collected data were processed through QUANL PC program and sorted into 5 types as follows: The first type was 'Choosing to withdraw life sustaining treatment', the second 'Withholding life sustaining treatment' regardless of the cost, the third is neutral type that claims that humans have the right to decide the death and life, and demands the proper legalization to protect such rights, the fourth type agrees to withdrawal of life sustaining treatment, nevertheless, admits that one has a rigt to withhold one's own life treatment, categorized as self contradiction type. The fifth type believed that 'Life and death are providential' with the faith, therefore, such authority to decide life and death belongs to God, but not human beings. Conclusion: In conclusion, the lawyer's attitudes toward withdrawal of life sustaining treatment were grouped into five different types as follows: 'Choosing to withdraw life sustaining treatment', 'Withholding life sustaining treatment', 'Demanding legalization', 'Self contradiction type', and 'Life and death are providential'.

Manpower demand forecasting in private security industry can be used for both policy and information function. At a time when police agencies have fewer resources to accomplish their goals, forming partnership with private security firms should be a viable means to choose. But without precise understanding of each other, their partnership could be superficial. At the same time, an important debate is coming out whether security industry will continue to expand in numbers of employees, or level-off in the near future. Such debates are especially important for young people considering careers in private security industry. Recently, ARIMA model has been widely used as a reliable instrument in the many field of industry for demand forecasting. An ARIMA model predicts a value in a response time series as a linear combination of its own past values, past errors, and current and past values of other time series. This study conducts a short-term forecast of manpower demand in private security industry using ARIMA model. After obtaining yearly data of private security officers from 1976 to 2008, this paper are forecasting future trends and proposing some policy orientations. The result shows that ARIMA(0, 2, 1) model is the most appropriate one and forecasts a minimum of 137,387 to maximum 190,124 private security officers will be needed in 2013. The conclusions discuss some implications and predictable changes in policing and coping strategies public police and private security can take.
