The purpose of this study is to investigate the state of the dental health of adults, used self-reporting qestionnaire as objects of 923 residents living in nine districts at random among the sites of eleven town located in a County. The level of knowledge on dental health of adults in a County was 65.6 points out of 100 points, comparatively low. Accodingly, it is necessary for entire adults to have a dental health-related education and get high standard of knowledge. Especially, educational approach should be performed for groups of 40-49 years old, 50-59 years old, above 60 years old, male, no educational background, having only elementary and middle school education, not having any jobs, engaging in agriculture, doing business on their own and so on. When planning the contents of health education, one actually has to include the habit of amalgam, the factor in influencing on dental health as well as show an example such as how to brush teeth, checking point of proper brushing, how to grip toothbrush. The attitude score related to dental heath was 71.2 points out of 100 points, relatively low. Consequently, the change of attitude related the dental health among entire adults is necessary, particularily, the strategical approach is essential to change dental health connected to attitude positively for groups of male, having high school education background, office workers and the civil service. Besides, among dental health related symtoms, more that 30-40％ of objects showed negative attitude toward as the following cases; in case that plaque or food debris are attached to the teeth (40.8％), upper and lower teeth do not fit together(40.3％), you cannot sleep well because of toothache(31.0％), more than one tooth fall out(31.0％), you have loosing teeth(30.6％), the approach should be conducted to form attitude that dental care is necessry. The state of dental health through dental health related symtoms was 33.3 points out of 100 points, which was fairly satisfactory. However, dental treatment for the state of dental health should be executed in case of comparison of the dental health state according to general characteristics, the group who are above 60 years old, have elementary school education background, engage in aggriculture who are not good in dental health state as opposed to other groups. Furthermore, there should be dental care needs according to dental health related symtoms, particularly, more than 60-70％ of objects have experienced symtoms that plaque or food debris attached to the teeth, tartar is on the teeth so dental treatment should be peformed for a large number of adults. In addition, for the people who have indications that there was a cavity, more than one tooth loss, chilled teeth, toothache when chewing, loose teeth, upper and lower teeth do not fit together, you cannnt sleep well due to the toothach, etc, there should be care through dental treatment. The actual conditions of the hygine of the mouth was relatively good and the difference of the actual state of dental health care in terms of general characteristics showed in only gender; female was more careful in dental health. Comparing the state of oral health synthetically, when they have symtoms, only 34.8％ of objects go to a dentist, 60.7％ are using passive or negative care such as gargling, tolerating or ignoring. There was many symtoms to care through dental therapy such as plaque or food debris get in between the teeth, tartar on the teeth, teeth are very cold, more than one tooth fallout, loose teeth, there is wrong amalgam, and so on, among symtoms to care passively or negatively. Therefore the education for proper treatment program should be performed. As a result of dental health-related knowlege, attitude, health state, verification of correlation between the actual condition of care, the higher the dental heath-related knowldege becomes, the more positive the dental health-related attitude is, and the state of dental health, that is, the standard of the symtom of dental health diminishes. the care for dental health executed through more active method and the more positive dental health-related attitude is, the more active means they performed. Consequently, the high level of dental health-related knowledge should be necessary, the more positive the dental health-related attitude was, the more active method they adopted, therefore, the program is needed to form attitude related to the dental health positively. As the knowledge on dental health is increasing, the attitude is also positive, after all, the plan to increase the standard of knowledge on dental health should be contrived through education program related to dental health.

To investigate the applicability of hot water extract from Codonoposis lanceolata (CL) and fermented Codonoposis lanceolata (FCL) as functional food and cosmeceutical material, its total phenolic contents, total flavonoids, electron donating ability (EDA), SOD-like activity, nitrate-scavenging ability (NSA), reducing power were examined. Total phenolic contents of CL and FCL were 0.54 mg/100 g and 2.79 mg/100 g, respectively, and total flavonoids contents were estimated as 2.26 mg/100 g for CL and 6.16 mg/100 g FCL. The EDA of CL and FCL were 8.0$\sim$17.9% and 32.9$\sim$74.9%. The SOD-like activities of CL and FCL were 0.6$\sim$16.5% and 3.5$\sim$21.6%, respectively, and the activity was dependent on the sample concentration. The NSA was pH dependent, and was the highest at pH 1.2 and the lowest at pH 6.0. The NSA of FCL was higher than that of CL. The FCL extract showed the highest reducing power (0.65) at the concentration of 1,000 $\mu g$/mL. Based on the above results, we deemed that the FCL might have potential antioxdant activities.

Aspect Based Sentiment Analysis (ABSA), which analyzes sentiment based on aspects that appear in the text, is drawing attention because it can be used in various business industries. ABSA is a study that analyzes sentiment by aspects for multiple aspects that a text has. It is being studied in various forms depending on the purpose, such as analyzing all targets or just aspects and sentiments. Here, the aspect refers to the property of a target, and the target refers to the text that causes the sentiment. For example, for restaurant reviews, you could set the aspect into food taste, food price, quality of service, mood of the restaurant, etc. Also, if there is a review that says, "The pasta was delicious, but the salad was not," the words "steak" and "salad," which are directly mentioned in the sentence, become the "target." So far, in ABSA, most studies have analyzed sentiment only based on aspects or targets. However, even with the same aspects or targets, sentiment analysis may be inaccurate. Instances would be when aspects or sentiment are divided or when sentiment exists without a target. For example, sentences like, "Pizza and the salad were good, but the steak was disappointing." Although the aspect of this sentence is limited to "food," conflicting sentiments coexist. In addition, in the case of sentences such as "Shrimp was delicious, but the price was extravagant," although the target here is "shrimp," there are opposite sentiments coexisting that are dependent on the aspect. Finally, in sentences like "The food arrived too late and is cold now." there is no target (NULL), but it transmits a negative sentiment toward the aspect "service." Like this, failure to consider both aspects and targets - when sentiment or aspect is divided or when sentiment exists without a target - creates a dual dependency problem. To address this problem, this research analyzes sentiment by considering both aspects and targets (Target-Aspect-Sentiment Detection, hereby TASD). This study detected the limitations of existing research in the field of TASD: local contexts are not fully captured, and the number of epochs and batch size dramatically lowers the F1-score. The current model excels in spotting overall context and relations between each word. However, it struggles with phrases in the local context and is relatively slow when learning. Therefore, this study tries to improve the model's performance. To achieve the objective of this research, we additionally used auxiliary loss in aspect-sentiment classification by constructing CNN(Convolutional Neural Network) layers parallel to existing models. If existing models have analyzed aspect-sentiment through BERT encoding, Pooler, and Linear layers, this research added CNN layer-adaptive average pooling to existing models, and learning was progressed by adding additional loss values for aspect-sentiment to existing loss. In other words, when learning, the auxiliary loss, computed through CNN layers, allowed the local context to be captured more fitted. After learning, the model is designed to do aspect-sentiment analysis through the existing method. To evaluate the performance of this model, two datasets, SemEval-2015 task 12 and SemEval-2016 task 5, were used and the f1-score increased compared to the existing models. When the batch was 8 and epoch was 5, the difference was largest between the F1-score of existing models and this study with 29 and 45, respectively. Even when batch and epoch were adjusted, the F1-scores were higher than the existing models. It can be said that even when the batch and epoch numbers were small, they can be learned effectively compared to the existing models. Therefore, it can be useful in situations where resources are limited. Through this study, aspect-based sentiments can be more accurately analyzed. Through various uses in business, such as development or establishing marketing strategies, both consumers and sellers will be able to make efficient decisions. In addition, it is believed that the model can be fully learned and utilized by small businesses, those that do not have much data, given that they use a pre-training model and recorded a relatively high F1-score even with limited resources.

Objectives: This study was performed to evaluate the analytical method for PAH metabolites in human urine using enzyme hydrolysis and solid-phase extraction coupled with LC-(ESI)-MS/MS technique. Methods: We employed HPLC tandem mass spectrometry techniques with appropriate pre-treatment for analysis of 16 OH-PAHs in human urine. Samples were hydrolysis by ${\beta}$-flucuronidase/Aryl sulfatase, and target compounds were extracted by solid-phase extraction with a strata-x cartridge. Cross-validation was performed between Eulji University and Green Cross laboratories with 200 human urine samples. Results: The accuracies were between 90.3% and 118.8%, and precisions (relative standard deviations) were lower than 10%. The linearity obtained was satisfying for the 16 OH-PAH compounds, with a coefficient of determination ($r^2$) higher than 0.99. The results of cross-validation at the two organizations were compared by ICC (interclass correlation coefficient) values. The cross-validation results were excellent or good for all compounds. Conclusion: An analytical method was validated for low nanogram levels of 16 OH-PAHs in human urine. Also, satisfying results were obtained for method validation such as accuracy, precision and ICC of cross-validation.

This study attempts to find optimum mixing proportion of rice dasik with yam powder by adding rice powder in different quantity and using honey and oligosaccharide as a sweetener. The results of the mechanical test and the sensory test on rice dasik are as follows. Moisture content of honey added one had less moisture than oligosaccharide added one did while having more sugar content than that. In color, honey added one showed the higher L-value and a-value than those of oligosaccharide added one, but it had the lower b-value. In hardness, chewiness, gumminess, and cohesiveness, oligosaccharide added one was higher. As a result of the preference test, the group which was added with 20% of yam powder was the highest. Based on the results above, adding yam powder makes the preference of rice dasik high, and the one added with 20% of yam powder is the best for rice dasik when using honey and oligosaccharide. This study used honey and oligosaccharide as a sweetening ingredient to make rice dasik, but it is necessary to research dasik with various sweetners and their different ratios.

As the WTO system launches through the agreement of Uruguay Round, the Government has to revise the office regulations or reform the system. Also, Integrating and Coordinating the like affair in health care (i. e., children's home, industry health, school health, health manpower, the administration of health center, the administration on food hygiene, health environmental education, and so on.) which is now scattered into some government departments like the Ministry of Labor, the Ministry of Education, the Ministry of Home Affairs, the Ministry of Agriculture, and the Ministry of Environment, the Government has to prevent unspecialty, inefficiency, inconsistency, and uneconomy. The Government has to review and adopt above suggested the Proposal 1),2),3),4) of the Health Centers on the basis of the local autonomy law and it will help the successive settlement of the local autonomy system in Korea. According to the suggested proposal, the Central Government mainly takes charge of the Macro affairs as hardware, and transfer the Micro affairs as software into the Local Governments to attempt the appropriate functional allocation. To achieve it successfully, the Central Government also has to do the financial support, manpower training and technical support, allocation of health care resources, direction and control, research and development and the health care plan on the macro level. Local Governments which divided into the wide local government and basic local government also have to do their best for health improvement of the community societies like plan of health care program, implementation of health care service program, taking charge of the affairs of health insurance, activation of community residents' participation and security of health care resources etc. To achieve this goal, the Government have to be more active and reformative, the related social and health agencies and educational agencies have to cooperate and support for the goals, and especially, the community residents have to participate actively and voluntarily, When all these conditions promote, local health care administration will be developed, and health level of community residents will be secured. And going one step forward, the country and people will be more healthy
