Objectives: The purpose of this study was to confirm the effects of an auricular acupressure (AA) program for smoking cessation in high school students from 2015 to 2017. Methods: The study investigated 12 high school students who had been smokers. Subjects were treated for three years. Each program was composed of five AA treatments. Average daily smoking and adverse reactions were checked for one week before each procedure. The AA was administered weekly at the endocrine point, lung point, throat point, nasal fossae point, bronchial tube point, and mouth point. Results: The mean number of cigarettes smoked per day after each year of treatment significantly decreased from 5.33±3.58 to 3.54±2.08 in 2015 (p=0.046). However, it increased from 5.75±2.30 to 6.00±3.61 in 2017 (p=0.80). The number of cigarettes smoked before treatment was found to be higher than the number of cigarettes after treatment in the previous year. No significant results were obtained from analysis of the change in the amount of smoking within each year. Conclusion: Social influence, such as the subject's academic stress and peer relationships, may have been a major factor in the change in the amount of smoking. Although the AA did not show a strong effect in smoking cessation, it appears to have value as a supplementary means of stopping smoking.

The result of this study may be abstracted as follows. 1) The study was done on 48.3% seniors(138), 34.3% sophomores. and 17.5% juniors mostly ranging in age from 21 to 22, the largest number of students at 38.1%(109) were Christian. followed by 31.5%(90) were Confucian. 20.6%(59) who were Catholic. and 9.1%(26)who were Buddhist. 2) Concerning the economic views. 46.8%(134) preferred Capitalism 40.9%(117) preferred a combination of Capitalism and Socialism, 8.7%(25) were for more or less Socialistic in view point, and 3.5%(10) for Socialism. 3) Among the internal factors causing poverty, 'lack of ability(knowledge)', scored the highest at 3.528, and 'beauty or appearance' scored the lowest at 1.570. Social factors scored high in 'bad economic/tax policies' at 3.374 and 'low average in wages' at 3.364. Among family matters, 'not much money at home' scored the highest at 3.273, and 'low expectation of success in poor families' scored the lowest at 2.315. On concerns of fate and destiny. 'bad luck' turned out to be the most likely cause of poverty with the score of 2.619. and 'destined poverty' was the least likely cause with the score of 1.969. 4) The high scoring economical consequences of poverty was 'not able to do as one desires' at 3.965, and 'no money to buy things wanted' at 3.804. 'Gets tired of life' (4.028) scored high in psychological consequences showing that poverty affects these matters greatly. 'Looked down on by others' (3.538) scored high in social circumstances, and 'feels like a burden to society' scored low at 2.080. Among family matters. 'hard life' scored high at 4.210, and 'low morality' scored low at 1.972. 5) Significant differences(p= .00) were found between economic views and what significance certain internal factors caused poverty these differences were also related to a reliance on religion, economic views, and economic status. Significant differences were also found between economic status and internal factors causing poverty(p= .04), economic point of view and social factors(p= .01). and economical point of view and luck related matters, (p = .01) When the consequences of poverty were considered. psychological factors such as 'hate towards oneself', 'tired of life', and 'afraid of the future' showed significant differences in relation to economic status. (p = .02) Family matters also showed significant differences in relation to economic status(p= .03), With personal characteristics and wealth causing factors, significant differences were found between a person's economic point of view and ecinomic status when considering and internal or social factors.

Purpose: To evaluate the difference of the movement of the mandibular condyles between trans cranial and panoramic TMJ radiographs to view the movement of the mandibular condyles. Materials and Methods: Thirty-four paired transcranial and panoramic TMJ radiographs of patients were used to evaluate the movement of the mandibular condyle. The distances, from the most superior point of the mandibular condyle to the most inferior point of the articular eminence on both radiographs, were measured. The measurements were taken at closed state and maximum opening state of each radiograph on both side. Differences between matched pairs were analysed by paired t-test, with significance established at P<0.05. Results and Conclusion: The mean distance, from the most superior point of the mandibular condyle to the most inferior point of the articular eminence on both radiographs, was statistically different at each side (P<0.05). At closing state, the mean distance measured on panoramic TMJ radiographs was longer than on transcranial radio-graphs (0.85 mm at right side, 1.20 mm at left side). But at maximum opening state, the mean distance on transcranial radiographs was longer (1.00 mm at right side, 0.62 mm at left side) than panoramic TMJ radiographs.

This study introduces an algorithm for determination of hypocentral parameters using phase analysis and two-point ray tracing to enhance accuracy and stability of computations. When the magnitude of earthquake is relatively small(usually $m_{b}$<3.2), the PmP phase which looks like the first arrival phase may be observed without observing the Pn phase. In this case, the hypocentral parameters calculated by the existing method using the first arrival of P and S phases and by the method developed in this study using PmP and SmS phases show large differences. The computational results of determination of hypocentral parameters for actual earthquake events show that this method gives much smaller rms errors than the existing methods do.o.

An automatic titration system using a PC-camera with a color filter on its lens was used in the $KMnO_4$ consumption test of tap water and distilled water in relation to blank tests. The very faint pink color of titration end point could be effectively detected by using a yellow cellophane paper as a color filter. The average hue value (Havg) of 192 pixels in the image of the sample solution being titrated was computed and followed up at regular time intervals during titration in order to detect the titration end point. The Havg decrease of 2 degrees from the average of first 10 Havgs was regarded as reaching the end point. The volume of 0.01N $KMnO_4$ consumed by a tap water sample was $0.728{\pm}0.022ml$ in manual titration and $0.735{\pm}0.013ml$ in automatic titration (p=0.580). The volume of 0.01N $KMnO_4$ consumed by a distilled water sample was $0.383{\pm}0.015ml$ in manual titration and $0.367{\pm}0.015ml$ in automatic titration (p=0.252). The high p-values for t-test suggested that there were good agreements between manual and automatic titration data and the automatic method proposed in this article was considered to effectively replace the manual titration.

In this paper, an attempt is made to analyze the impulsive stress directly underneath the concentrated impact point for a supported square plate by using the three-dimensional dynamic theory of elasticity and the potential theory of displacement (stress function) on the supposition that the load, F$_{*}$0 sin .omega.t, acted on the central part of it. The results obtained from this study are as follows: 1. The impulsive stress cannot be analyzed directly underneath the acting point of concenrated impact load in privious theories, but can be analyzed by using the three-dimensional dynamic theory of elasticity and the potential theory of displacement. 2. Theorically, with increasing the pulse width of applied load, it was possible to clarify that the amount of stress in the point of concentrated impact load was increased and that of stress per unit impulse was decreased. 3. The numerical inversion of laplace transformation by the use of the F.F.T algorithm contributes the reduction of C.P.U time and the improvement of the accuracy or results. 4. In this paper recommended, it is found that the approximate equation of impact load function P (.tau.) = A.tau. exp (-B.tau.), and P (.tau.) =0.85A exp (-B.tau.) sinC.tau. could actually apply to all impact problem. In compared with the experimental results, the propriety of the analytical method is reasonable.

This study was performed to analyze the influence of pollutant loads characteristics on the point and non-point sources in Saemangeum watershed area using Hydrological Simulation Program, Fortran (HSPF). The simulation items were flow, BOD, T-N, and T-P(2007~2010). The pollutant loads trend reflects the precipitation. Specifically, the point source loads were almost constant, but the non-point source loads were influenced in the precipitation. It was found that the effect of non-point source is larger than point source. The water quality had a clear trend by the season. However, pollutant loads did not show distinct seasonal changes. The reason is that the pollutant concentration is diluted by the increased flow at summer season. Therefore, it is important to control the non-point source in order to manage water quality in the region. For the management of Saemangeum lake, it is need to control of supplied pollutant loads from Saemangeum watershed.

This paper evaluated the influence of point source and flow events on inorganic nitrogen fractions at 17 sites of Taechung Reservoir during 1993${\sim}$1994. Total nitrogen (TN) averaged 1.53 mg/L during the study and ranged between 0.70 and 2.56 mg/L. Dissolved inorganic nitrogen(DIN) accounted for >90% of TN regardless of season and location, indicating a nitrogen-rich system showing eutrophic${\sim}$hypereutrophic conditions. Some 67${\sim}$94% of DIN was NO$_{3}$-N, whereas mean level of NH$_{4}$-N was less than 5% of DIN. During monsoon 1993, dilution of NO$_{3}$-N was evident in the headwaters as a result of mixing of lake water with rain water, while NH$_{4}$-N increased>100% compared to the premonsoon. Values of NH$_{4}$-N had a positive correlation with rainfall (r=0.85; p<0.001) and negative correlations with theoretical water residence time(r=-0.90; p<0.001) and conductivity(r=-0.78, p<0.001), respectively. These outcomes suggest that NH$_{4}$-N came from external input from the watershed during the monsoon. In both years, mean TN was greater in the mid-lake sites than any other sites. A great amount of TN in the mid-lake was most pronounced in monsoon 1994 because of an accumulated influence of the point sources during low inflow. Overall data suggest that concentrations of TN in this system did not show large differences along the longitudinal gradients and its distributions is likely determined by point-sources rather than inflow regime.
