Large accidents such as the recent to the ringing years Pat disaster they become apparent in the human resources, the cause of the accident is also the site corresponding manual member and management blind spots, are aggregated such as safety frigidity. Big problem is safe frigidity of workplace than accident. It is also a reason to introduce a punitive damages system in offices and business owners that caused the direct safety accident from this point. Punitive damages agent and compensation for mental damage, by so as to compensate for far more money than the actual damages, which carry a punishment nature to prevent a situation where the tort is repeated. Currently, it admits "compensatory damages system" corresponding to the damage that gave basically damage by law, but are subject to criticism that not properly relief victims. However, there is a need for the introduction of punitive damages system for safety accident prevention. This is, this system, while to prevent the recurrence of the reverse safety accident, strive to investment and management for safety, healthy companies can operate in the direction of giving more opportunities, national companies that are ignoring and threatening the safety, but to leave because the match also to social justice.

Asphalt Plug Joint(APJ) is an buried expansion joint that enabling the smooth connection of expansion gap and road pavement by filling the gap with bituminous mixture of 20% bitumen and 80% aggregate by weight, so it secures evenness and expansion or contraction using the material's properties. Although APJ is designed to have a 6-7 year lifecycle, there are some cases where it is damaged within the first six months. This early damage cause traffic congestion due to frequent repair works, and social cost exceeding the installation cost of the joint. So, in this research, we have developed a new system of Buried Folding Lattice Joint(BFLJ) which can overcome the disadvantages of APJ, and have analyzed and compared it's performance with the conventional APJ through experiment with specimens. As a result of the experiment, APJ had crack formation on both ends of the gap plate, spreading to the surface of the expansion joint. With this result, we can conclude that the reason for early damage is the tension failure due to the concentration of strain in the asphalt mixture along the end of gap plate and the debonding along the joint section. In contrast, the newly developed BFLJ induced even transformation in the joint by applying moving stud and high performance material, and resolved APJ's disadvantage of strain concentration. Therefore, it could be seen that the newly developed BFLJ could overcome the disadvantages of APJ and prevent early damage.

Lately due to the sudden growth of the construction of an apartment complex in domestic market, many construction companies are eager to provide various public facilities to increase the apartment distribution rate. An introduction of a fitness center is popularized as a part of such development. There has been a continuing development in a private fitness based on analyzing the user's data. However a public fitness is quite different from the private in terms of a user's classification, preference rate, the pattern of use, and location which requires a different facility plan. Nevertheless, all these days a public fitness in an apartment house has been developed without a specific facility plan based on relevant materials. It is worried that such development would cause the facilities not to function as appropriate resident facilities and sink to idle ones. Therefore the purpose of this paper is to make the standard considered in facility planning in future and the base to guide an applying method. In the paper the present condition of fitness centers inside apartment houses has been compared to analyze the progress of the existing facilities and the appropriateness of the organization and the structure division. The result of the research shows that public resident facilities is not the place to perform passive role for fixed activities but one to form a community through the human relationship based on the facility. Therefore a fitness center inside the apartment complex have to be designed to provide service and leisure space as one of main community facilities for residents. To obtain this purpose, when choosing facilities of an apartment complex, first of all the residents' standard of living, apartment size, residents' distinction rate of age and sex, the needs of the times should be fully considered Secondly, the size of each facility space have to be decided based on the practical data analysis in facility use such as space preference, average staying time. Also, future living culture requires the change of the function and space according to the change of social values, so continuing research and data analysis are required to related to fitness center inside an apartment complex in order to present systematic approaching method and the paper will be expected to be a little step toward it.

This research aims to provide a solution for the improvement of private security according to the change in criminal environment. The main cause of crime can be found in the anti-functional dimensions including value set disorder, social phenomenon variation, information-based, globalization and urbanization. In this environment, the private security sector has dramatically increased in a quantitative viewpoint, but it is insufficient in a qualitative viewpoint. This paper recognized this problem and demonstrates a solution for improvement through classifying elements of private security into relevant legislation, education institutions, security companies and security associations. The analysis result is a follows: First, motivation and satisfaction rate of escort and security related major has shown to be high. However, respondents evaluated the guard educational institution negatively. Second, the motivation of entering into the private security sector for internal staffs has shown to be positive and sound. However, the job satisfaction rate has shown to be low due to excessive competition, negative perception of occupation and low earning. Third, respondents gave an average mark to the Security Association's management and operation. In addition, the mutual-aid project received the same mark. Negative feedbacks were given to the protection of member's interest and to association operation and policy, while positive feedbacks were given to the degree of member's cooperation towards association policies.

Purpose: We conducted this retrospective epidemiological study to assess the incidence and severity of lower extremity injuries in Korea Methods: For this study, we retrospectively reviewed nationwide lower-extremity injury data compiled from 2001 to 2003 based on the National Injury Database, what included National Health Insurance Corporation (NHIC), Car Insurance, and Industry Insurance data. Data were standardized in terms of demographic characteristics, region, and socioeconomic status by using NHIC data. To assess the degree of the injuries, we used the Modified Abbreviated Injury Scale (MoAIS), what has been changed from the International Classification of Disease-10 (ICD-10) code. By using the Excess Mortality Ratio-adjusted Injury Severity Score (EMR-ISS), we classified the degree of severity into four categories: mild, moderate, severe and critical. Results: From 2001 to 2003, lower extremity injuries increased slightly, with a yearly average of 2,437,335. Insurance data should that lower-extremity injuries were the most common, followed by upper-extremity injuries. Significant difference were seen in the numbers of lower extremity injuries based on gender and age. As for provinces, Seoul and Gyeongi provinces had the highest numbers of cases. Junlabukdo had the highest rate of 55,282 cases per 1 million people for standardized gender and population. The annual incidence of the insured patients with lower extrimity injuries was higher than the employer's medical insurance contributions to the medical insurance program. Daily cases occur most often in May and June, with the lowest occurrences being in January and February. Conclusion: The result of this study shows that lower extremity injuries comprised common cause of all injuries. In addition, differences associated with gender, location and socioeconomic status were observed. Further studies are needed to find reasons and then this knowledge will allow strategies to prevent the lower extremity injuries.

The purpose of this study was to ascertain whether or not to recover the spontaneous circulation of patients with cardiac arrest before arrival in the emergency room for 5 years (2012 to 2016), and try to investigate the factors affecting this. In this research, we used the "raw material for acute cardiac arrest survey" conducted in "Disease management headquarters" from 2012 to 2016 for the whole country of our country as the main material. In this study, 136,212 cardiac arrest patients were analyzed in the study data of the cardiac arrest in the country during the 5 years from 2012 to 2016. We performed a Chi-square analysis to analyze the recovery of spontaneous circulation before arrival in the emergency room according to general characteristics, social·demographic characteristics, and developmental characteristics. and We performed a Binary logistic regression analysis to determine the factors affecting the recovery of spontaneous circulation. The analysis results of this study show that whether CPR sustained transport before endoplasmic reticulum arrival, whether to witness an acute cardiac arrest before arrival in the emergency room, the type of general cardiopulmonary resuscitation, the location of acute cardiac arrest, the acute heart Causes of stoppage cause factor of whether spontaneous circulation recovery recovers before arrival of the endoplasmic reticulum(P<0.001, P<0.01). Therefore, it is necessary to strengthen systematic government health policy implementation and dissemination and health education focusing on factors that affect recovery of spontaneous circulation of cardiac arrest patients.

Leaks in underground pipelines can cause social, environmental and economical problems. One of relevant countermeasures against leaks is to find and repair of leak points of the pipes. Leak noise is a good source to identify the location of leak points of the pipelines. Although there have been several methods to detect the leak location with leak noise, such as listening rods, hydrophones or ground microphones, they have not been so efficient tools. In this paper, acoustic emission (AE) sensors and accelermeters are used to detect leak locations which could provide all easier and move efficient method. Filtering, signal processing and algorithm of raw input data from sensors for the detection of leak location are described. A 120m-long pipeline system for experiment is installed and the results with the system show that the algorithm with the AE sensors and accelerometers offers accurate pinpointing of leaks. Theoretical analysis of sound wave propagation speed of water in underground pipes, which is critically important in leak locating, is also described.

Bankruptcy of firms in Korea can cause distress of financial institutions because these institutions have disterssed bond. Accordingly, social and economical spill-over effects by these results are very big. Even after the difficult times of IMF crisis had ended, bankruptcy of information-based small-medium companies and venture firms listed on the KOSDAQ has been continued. In this context, this study developed and adopted failure prediction models for which discriminant analysis was used. Samples of this study was 81 firms respectively for both failed and non-failed firms listed on the KOSDAQ between the year of 2000 and 2007. The results of this study are as follows. First, the accuracy of classification of the model by years was $74.5%{\sim}76.5%$, and the accuracy of classification of the mean model was $69.6%{\sim}80.4%$. Among the models, the mean model of -one year, -two years, and -three years was highest in accuracy of classification (80.4%). Second, accuracy of prediction of final model adopted on validation samples showed 85% before one year of bankruptcy. The results of this study may be significant in that the results may be used as early warning system for bankruptcy prediction of KOSDAQ firms.

The 16 century Yulgok had lived have been evaluated as the golden age of Seonglihak(性理學) in Korea. However, on the contrary, excessively desperate was the real social and political situation which Yulgok had descirbed. Therefore, eventhhough the Seonglihak centered-reseach is meaningful, this research had the limitation in analyzing the politics in those times. In studying Yulgok's thought, the established researches had focused on philosophic theory centered-orientation. However escaping from that orientation, in this essay I try to restructure Yulgok's enlivened political experience that he had worldly seen, felt, heard and performed in 16th's real politics. While the established researches had absorbed in Kyeonghak(經學, the interpretaion of Confucian Cannon), I try to restore Kyeongse(經世, governing and managing the state) based on Yulgok's worldly political experience. The major concept on which I have focused is Pye(弊, the abnoxious custiom in political and official sphere). Yulgok's offical life had begun with the problematic of how to overcome Pye inherited by Kwongan(權奸, a politically villainous retainer). In the process, he had focused on the worldly performable issue, Minsaeng(民生, the livelihood of the people), not on the abstract and theoritical concept, Min(民, the people). He recognized the cause of desperate situation had resulted from Pyebeob(弊法, the obnoxious law, its system and its execution), and tried to reform Pyebeob in the various way. The next concern of Yulgok came to Pyejeong(弊政, the obnoxious politics, its system and its execution), which interrupted not to reform Pyebeob. According to Yulgok, Pyejeong resulted from the wrong fulfilment of official-scholar elite in government, and the distorted public opinion in governemt. This fact demonstrates two elements mentioned above had common root of the absence of communication of public opinion. Yulgok recognized the importance of Ui(議, the discussion) than of Ron(論, the dabate) and then reviving Ui, Yulgok had tried to arrange the foundation for the communication of public opinion in political sphere.

A joke (才談, 재담) is "the most interesting and witty language unit" in our speech. However, the search of a joke is still starting. Although joke are related to the witty and interesting talks, stories, songs and plays, the actual object of a joke is only the witty and interesting talk. A joke is witty talk that is interesting or laughter-inducing. Many Jokes can be found in the traditional Korean funny performing arts (演戱, 연희). This is because these art forms are performed in open yards, which necessitated amusing the audience, amusement, in its turn, required jokes. Jokes in the traditional funny performing arts can generally be classified as follows: 1) Jokes related to a situation: These include right words at a given situation, exaggerating words, diminishing words, deviancy words, and cause-effect words. 2) Jokes related to discourse: These include enumerating words, amplificatory words, contrasting words, fluently lying words, undeniable words, purposely unknowing words, and deliberately incorrect words. 3) Jokes related to vocabulary: These include synonym, similar words, changed word-ordering words, and incorrect words. 4) Jokes related to pronunciation: These include homonyms, and anti-homonyms. Although there may be other jokes, those presented above are typical ones. A joke is "the result that human being can achieve when he/she has overcome natural and social difficulties and is left with only a free and creative spirit." Jokes are necessary in all ages and everywhere. Today, more varied and high-level jokes can be created by developing the diversity of jokes in traditional funny performing arts. Also, I expect new sorts of jokes, because a joke always demands a creative spirit.
