In this study, containerized seedlings of Pinus densiflora (2-0) were planted in Iso-ri, Hwadong-myeon, Sangju-si, Gyeongbuk on April, 2015. It was planted by lightweight planting auger that Kyungpook University has developed and mattock which is the general planting method of containerized seedlings. With the square planting method ($1.8{\times}1.8m$), 225 trees were planted respectively and about 2 years of initial growth, survival rate and seedling quality index (SQI) were analyzed and investigated. According to the analysis result, the average root collar diameter (mm) of planted containerized seedlings that used lightweight planting auger and mattock reached 3.77 and 3.94 in 2015, 18.73 and 15.32 in 2016, and 27.8 and 23.9 in 2017 respectively. In addition, the average height of containerized seedlings rated 33.4 and 33.4 in 2015, 89.8 and 74.7 in 2016 and 120.7 and 97.9 in 2017. It turns out that the height of initial growth of containerized seedlings that are planted by lightweight planting auger were much higher than mattock. The survival rate of the containerized seedlings that used lightweight planting auger was also higher by 10% than that used mattock. Also, H/D rate (healthiness) and T/R rate were almost the same, however, for the SQI, 0.60 was for lightweight planting auger and 0.24 for mattock. It seems like the lightweight planting auger is more advantageous than mattock in initial growth.

This study examines children's responses on Audie music activity based on Gordon's Music Learning Method. Subjects of study were 3 five year old children(2 boys, 1 girl) in kindergarten. Data collection drew from participatory observation, researcher journal, the classroom teacher interview. Where more specific data were necessary, video and digital camera recorded. The data were described, analyzed, and interpreted. The main findings in this study are as follows : The children who participated in Audie music activity showed desirable changes in many ways. Their music listening attitude was the one that changed most remarkably. At the beginning activity application, the children were not naturally and could not listen attentively while researcher was singing song without words. Gradually children could listen attentively to the researcher's singing without words. Through the Audie music activity, the children began to think carefully the tone and rhythm of music and to express themselves freely and creatively. At the beginning activity application, the children who showed negative responses and blocked up activity became gradually able to show positive aptitude and to amuse. Also the children who showed passive attitude and no responses became gradually able to react spontaneously.

In order to investigate the relation between the phytoplankton and the catch fluctuation of set net fishing grounds located in the coastal waters of Yeosu, phytoplankton observations on the fishing ground were carried out by the training ship of Yeosu, Fisheries University from April to November in 1990, and the data obtained were compared with the catch data from the joint market of yeosu fisheries cooperative society in 1990. The results obtained are summarized as follows: 1) The phytoplanktons were more appeared in summer than in spring or autumn and their quantity was much in the shore of Dolsan-do, and little in the offshore waters distributed in the shores of Sori-do and Sejon-do, Thus, the quantity of the planktons could be used for estimating the distribution of watermass. 2) The fishes caught by the set net were arranged in the order of catch amounts as follows: Spanish mackerel > Hair tail > Common mackerel > Sardine > Anchovy > Horse mackerel > Yellow tail. The catches of anchovy and Sardine were high in April to May and Hair tail. Horse mackerel and Common mackerel were caught from June to October. But Spanish mackerel were caught during the whole period of fishing. 3) The catches by set nets showed a correlation with the quantity of phytoplanktons. The planktons appeared most in the inner waters. influenced largely by the inflow of land waters in summer. and the catches were high in summer when the offshore water was distributed least. Therefore, the most important factor influencing the catches were regarded to be the productivity of food organism in inner water into which abundant nutrients were supplied by the inflow of land waters. That is, the fluctuation of catches by set nets seemed to be influenced mainly by the productivity of food organism.

A retrospective study was conducted to determine the patterns of Temporomandibular Disorder(TMD) among adolescents (12-19 years) over last ten years. 174 patients who had visited the Oral medicine of Pusan National University Dental Hospital in 2000 and 491 patients in 2008 were found on chart review. The results obtained were as follows : 1. The number of adolescent patients was significantly increased in 2008 than in 2000, especially in male. 2. Bruxing, clenching, holding habits and bad sleep hygiene were highly increased more in 2008 than in 2000. 3. Osteoarthritis was significantly increased in 2008 than in 2000 and anterior disc dislocation without reduction was slightly increased. 4. The ratio of male to female adolescent patients with osteoarthritis was remarkably increased. Among the patients who had holding, bruxing, clenching habits, significantly increased osteoarthritis found to be common. This could imply holding, bruxing, clenching habits are prominently associated with increasing risk of developing osteoarthritis.

This study seeks to identify the effects of light pollution and environmental factors on Great Tits(Parus major) bird's chirping at dawn. For this research, the campus of Sanji University, Wonju, South Korea was selected as the area with light pollution and the western forest of the Chiaksan National Park was chosen as the natural area herein. The Recording period was between March 26th and May 30th, 2014. As a result of analyzing the chirping time according to light pollution, it was found that the light pollution area clearly showed earlier chirping time than the natural area (p<0.05). Great Tits(P. major) normally start their first chirping before sunrise and in most of the days under investigation of this research, those in Sanji University started to chirp earlier. This faster chirping time seems to improve the chance for the female birds to mate with immature males thus, baby birds hatch earlier than the appropriate breeding season and results in the lack of feed resources. The correlation between Great Tits'(P. major) dawn chirping and environmental factors were investigated herein including the time of sunrise, civil twilight, navigation twilight, astronomical twilight, average temperature, highest temperature, lowest temperature, time of moonrise and cloudiness. The first chirping time of wild birds in the day was found to have correlations with all of the environmental factors excluding the time of moonrise and cloudiness. Great Tits(P. major) started their first chirping before sunrise when the day started to break around civil twilight. Along with the earlier sunrise and higher air temperature, their dawn chirping time was also quickened. The time of moonrise and cloudiness did not show a correlation and further follow-up studies will be necessary in this regard.

Due to the growth of population and industrial development at the coastal cities, there has been much increase in necessity to effective control of the wastes into the coastal water and river. The amount of disposal at those waters has been increased rapidly and it is necessary for us to track of it in order to keep the water clean. The investigation and research related to the water quality in this region have been conducted continuously but the systematic survey of the disposed wastes at the bottom was neglected and/or minor. In this study we surveyed the status of disposed waste distribution at the bottom coastal water and river from the scanned images. The intensity of sound received by the side scan sonar tow vehicle from the sea floor provides information as to the general distribution and characteristics of the superficial wastes. The port and starboard side scanned images produced from a transducer borne on a tow fish connected by tow cable to a tug boat have the area with width of 22m∼112m, and band of 44m∼224m. All data are displayed in real-time on a high-resolution color display (1280 ${\times}$ 1024 pixels) together with position information by DGPS. From the field measurement and analysis of the recorded images, we could draw the location and distribution of bottom disposals. Furthermore, we made a database system which might be fundamental for planning the waste reception and process control system.

The purpose of this study was to examine the influence of type of malocclusion and orthodontic treatment awareness on quality of life among orthodontic patients in the region of Busan as well as to develop an educational program tailored to the type of malocclusion as a way to improve quality of life. A survey was conducted for approximately 6 months from December, 2015, and the answer sheets from 472 respondents were analyzed. The most common painful area was the teeth, and this case was most predominant in the respondents with level 2 malocclusion, who differed from others in that regard (p<0.001). Regarding the relationship between satisfaction with orthodontic treatment and quality of life, respondents who were more satisfied currently and who were neither quite confident nor quite unconfident were ahead of their counterparts in quality of life. Concerning the reason for receiving orthodontic treatment, quality of life was lower among patients who started to receive treatment due to pronunciation problems (p=0.013), chewing difficulty (p<0.001), and temporomandibular joint click sound (p<0.001). With regard to influential factors on oral health-related quality of life, time for starting to receive orthodontic treatment was most influential (p<0.001), followed by current satisfaction (p<0.001), changes in confidence (p=0.003), self-rated teeth status (p=0.008), and type of occlusion (p=0.019). Therefore, accurate analysis of the oral health status of orthodontic patients and customized oral health education are required to improve quality of life even during the period of orthodontic treatment.

This study was conducted to provide basic data for realistic applicable changes of sirens by identifying the stress due to the currently used sirens and the need for improving siren. The data was collected from an online survey of 267 subjects who voluntarily agreed to join this study from August 2019 to September, 2019. A structured questionnaire was used as a research tool. The results were analyzed by means and standard deviations, percentages and frequency analysis, and independent t-tests using SPSS. For the current workplace emergency siren type, it is believed that the number of hybrid formats was 143, the most negative opinion of the siren is high at 132, so periodic replacement is needed. For contextual stresses, the highest was 4.35 ± 0.94, when the siren was heard during bedtime. In the stress during sleep, which was based on the daily mean number of movements,, a statistically significant difference was shown between groups of 9 or more movements and below 9 movements (p <0.05). The type of siren paramedics wanted was 'soft music' and 'sound of nature'. More than half of 168 people (62.9%) wanted to replace the current siren, and 163 (91.6%) wanted that periodically within 24 months. Therefore, it is necessary to improve the siren.
