The purpose of this study was to investigate determinants of stop smoking. The data on which the analysis was based come from a survey of 355 middle-aged men in Seoul. The data was analyzed using proportion, x²-test, Pearson's Correlation Coefficient and Stepwise Multiple Regression. The following were the results; 1. Success rate of stop smoking is 19.9% of 229 persons who attempted to quit smoking. 2. As for the number of quit attempts, 33.3% of ex-smokers tried once; 25.4% of current smokers tried twice. 3. As for methods of quit attempts ex-smokers showed higher tendency in using will power and books/guides than current smokers who in using will power alone. 4. For the attitudes on smoking of family, the majority of ex-smokers and current smokers were opposed absolutely. 5. The main opposite to smoking were wives in cases of both ex-smokers and current smokers, but More ex-smokers answered that the main opposite to smoking were others than current smokers. 6. As for the measures of smoking in the office, more ex-smokers answered inviting than current smokers and more current smokers assigned a smoking spot than ex-smokers. 7. Majority of ex-smokers approve of restriction at public spot strongly. 8. As for the attitude about caution on a cigarette case, more ex-smokers insisted than current smokers. 9. There was a relation between the degree of exposure about knowledge and the degree of knowledge. 10. Stepwise Multiple Regression portray that following factors influence stop smoking in order named. (1) attitude on the smoking restriction at public spot, (2) methods of quit attempt, (3) attitude about caution on cigarette case. Even so, it turned out that these factors alone can explain only 20% of self-examination. Therefore study for the other factors ought to be continued. I submit following suggestions ending this study. 1. Continuous study of the other factors affecting stop smoking must be carried on. 2. Since there was a relation the degree of exposure about knowledge and the degree of knowledge, efficient health education is required using campaign and mass media.

The spread and damage of COVID-19 are putting significant pressure on the world, including Korea. Most countries place restrictions on movement and gathering to minimize contact between citizens and these policies have brought new changes to social patterns. This study generated traffic volume data on the scale of a road network using taxi movement data collected in the early stages of the COVID-19 third pandemic to analyze the impact of COVID-19 on movement patterns. After that, correlation analysis was performed with the data of confirmed cases in Daegu Metropolitan City and Local Moran's I was applied to analyze the effect of spatial characteristics. As a result, in terms of the overall road network, the number of confirmed cases showed a negative correlation with taxi driving and at least -0.615. It was confirmed that citizens' movement anxiety was reflected as the number of confirmed cases increased. The commercial and industrial areas in the center of the city confirmed the cold spot with a negative correlation and low-low local Mona's I. However, the road network around medical institutions such as hospitals and spaces with spatial characteristics such as residential complexes was high-high. In the future, this analysis could be used for preventive measures for policymakers due to COVID-19.
Tumuli located in Chodang-dong in Kangreung City are sitesexcavated by the Museum of Kangreung University in 1993.Ofthese sites, a gilt bronze crown and gilt bronze sword with ring pommel with a tri-leaf ornament were excavated from the B-16tumulus. Underneath the gilt bronze crown was the gilt bronzes word with ring pommel with tri-leaf ornament, and these artifacts were treated with Polyurethane foams on the spot followed by special measures for conservation. This manuscript describes measures for conservation andanalysis with regard to the gilt bronze crown, gilt bronze sword with ring pommel with tri-leaf ornament and gilt bronze beltornaments. Bronze on the gilt bronze crown was completely corroded, therefore it was consolidated together with soil in the back of the artifact with Paraloid B72 after cleaning. Polyurethanefoams bottom was finished by applying the mixture of Epoxy resinAW106 and HV935K with soil. On the sword with ring pommel, the wooden part of the hilt was coated with Paraloid B72 (in Xylene) and the blade was consolidated with Paraloid NAD-10 30% after desalting with Sodium sesquicarbonate method. The gilt bronzebelt ornaments were treated with 3% Benzotriazole, coated with Paraloid B72 and then joined by using Cyanlacrylate. Specimens for the gilt bronze crown and gilt bronze belt ornaments were produced and gilding layers were examined under a metallographic microscope. The gilt bronze crown and the gilt bronze belt ornament maintained relatively good gilding quality with uniform gilding layers. Analysis of wood for the sheath of the sword with ring pommel revealed it to be Juglans mandshurica. Further more, analysis of constituents for a blue colored grassbead from dissolution of Polyurethane foams found it to be from the $Na_2O$-CaO-$AI_2O_3$-$SiO_2$ family.
As year passes, terrorism is gradually increasing. Its target has becom various and arbitary, and recently, terrorists are aiming for national major facilities wich include multiplex facilities. Although special security guards took charge of its defence system from 2002, they have failed to establish its system firmly due to some institutional inertia. And 'Professionalism' appeared to be the mattter, according to the spot-probe and interviews. The purpose of this essay is to devise measures to develop sepecial security system including its specialization through investigating current educational training system. In order to attain professionalism, establishment of new proffessional school, division of current education system(into common education and full-course education), and reinforcement of substantial inspection activity should be preceded. Moreover, inspection activity should include standards for engaging instructors, establishment of compilation committee for editorial supervision, and establishment of clear educational policy. I hope the developmental measures in this essay to be speedily actualized with endeavor from police, security association, academic circles.
The performance of ultrasonic testing systems for industrial or medical purpose largely depends on the performance of ultrasonic transducers. Generally, the information about an ultrasonic transducer performance characteristics are expressed by the ultrasonic R/F signal back from a reflector and its frequency characteristics in the data sheet provided by manufacturers. In case of focused ultrasonic transducers, the two pieces of information can, however, hardly assure that the focused ultrasonic transducer would produce well-focused C-scan images. Therefore, we propose the measured size of focal spot and the reconstructed shape of effective focal zone in the focused sound field as novel measures for the performance evaluation of the focused ultrasonic transducers. The process of getting the both measures of the transducers is conducted by the implemented software including sound field scanning and virtual 3D reconstruction functions which requires the echo of a point reflector. The proposed method could, otherwise impossible in the existing method, effectively and simply distinguish superior ones among many transducers made in the same specification and be also used to detect the performance degradation due to the aging of the transducers. Eventually, the quality of performance of the ultrasonic testing systems for industrial or medical purpose is secured.

As a large city advanced, the urban environment is becoming an issue. The contribution of vehicle emissions in air pollutants was very high according to the clean air policy support system (CAPSS). In order to improve the air quality in large cities, it is necessary to establish improvement measures by sources, analyzing the air quality of roadside. We divided Bucheon city into 4 regions to investigate the roadside pollutants of each district using the mobile laboratory (ML) and air quality monitoring station (AQMS). ML was used to measure pollutants emitted from vehicles and AQMS data was used as a comparison group of ML data. As a measurement result of pollutants in the roadside, the concentration of air pollutants in industrial & engineering complex area was the highest and concentration of air pollutants in residential & forest complex area was lower. By street, Bucheon-ro, Sinheung-ro, Sosa-ro, and Gyeongin-ro were identified as high concentrations. Therefore, further researches on preparing management measures for roads in the hot-spot area are needed.

The death toll in the Korean construction industry accounts for more than 50% of all business deaths. This is the highest level among OECD countries, and the government has proposed various solutions to this, but has not seen any significant effect. In order to strengthen safety responsibilities and obligations to CEOs of companies in the blind spot of punishment, including those who have the greatest authority and influence in the construction industry, the Moon Jae In government strengthened various laws, including legislation of the Serious Accidents Punishment Act. However, at this point in time, half a year later, it is still questionable whether such punishment has been strengthened and the effectiveness of fragmentary measures has been exerted. This paper attempted to present legislative policy directions for the problems of the current system and future improvement measures to contribute to reducing significant accidents in the CM/supervision industry among the various subjects of the construction industry.

Purpose : This study examined the relationship between oral health management behavior and subjective health perception by using a tool that measures health-related quality of life named EQ-5D. The findings are expected to provide fundamental data for developing diverse programs, including health- and oral-health-related educational media, to ultimately enhance people's health-related quality of life. Methods : Adults over the age of 20 were extracted from the raw materials of the 8th national health and nutrition examination survey conducted in 2019. Among them, 4034 were finally chosen as the study subjects after checking the response distribution of relevant questions and excluding inadequate samples. Variables included general characteristics, health management behavior, oral health management behavior, subjective health perception, and EQ-5D level. Cross-tabulation test, independent t-test, one-way analysis of variance, and linear regression analysis were conducted using SPSS 25.0. Results : EQ-5D, which measures the level of health-related quality of life, was high when the subjects had a medical check-up experience, no experience of unsatisfactory medical service, and did not get an influenza vaccination (p<.001). The quality of life was higher when the subjects received dental inspections, did not require treatment, and used oral care goods (p<.005). Health-related quality of life was also higher when the subjective health level and subjective oral health level were high. Conclusion : Results indicate that subjective health, oral health perception level, and quality of life together were high when people had a regular check-up, did not neglect treatment, and used oral care goods. Considering the findings of this study, check-up programs that are customized for each age group are necessary. Health-related quality of life could be enhanced through the provision of diverse medical services and active efforts to prevent any medical blind spot.

Since Equipment-Noises occurring in machine room penetrate wall-body and travel to the adjacent room in the form of air-borne sound and structure-borne sound, it is appearing as the main factor that injures a peaceful residential environment, and due to this, such noise-damage is currently increasing rapidly. Consequently, despite the measures for sound-insulation and soundproof against the equipment-noise penetrated wall-body is urgently required, but as the subjective evaluation considered for psychological response about the equipment-noise was not practiced, many dissatisfactions are still raising even after some measure was taken. On such point of view, this Research, at the spot, has actually measured the equipment-noise that had permeated various wall-bodies, and examined its physical characteristics, thence based upon this, has conducted Psycho-Acoustics Experiment and investigated the interrelation between the physical evaluation value and psychological reaction value. It is considered that such study result could be utilized as the useful material at the time of establishment of the Grading Standard for the insulation performance against the Architectural Plumbing Noise, in the future.
