Objectives: The mandible and other parts of the maxillofacial region suffer significant morbid injuries following road traffic accidents. Our study gives epidemiological description of mandibular fractures in Ghana and also evaluates the relevance of closed reduction and indirect fixation for managing mandibular fractures in low-resource health facilities in low-income countries like Ghana. Patients and Methods: This is a retrospective study involving 268 patients who reported to the Department of Oral and Maxillofacial Surgery of the Sunyani Regional Hospital with mandibular fractures from January 2010 to December 2019. Patient medical records were assessed for information on age, sex, fracture etiology, anatomic location of fracture, time of day of road traffic accident, and other associated injuries. Results: A total of 268 patients were included in this study (males, 216 [80.6%]; females, 52 [19.4%]). Motor vehicular accident (MVA) was the leading cause of mandibular fractures (202 injuries, 75.4%). Other etiologies included assault (39, 14.6%), gunshot (13, 4.9%), falls (12, 4.5%), and industrial accidents (2, 0.7%). Of the 161 male cases caused by MVA, 121 (75.2%) occurred at night and in the evening while the remaining 40 (24.8%) occurred in the morning and afternoon. Among all managed 222 patients, 212 (79.1%) were treated with closed reduction and indirect fixation technique while 10 (3.7%) were treated with open reduction and direct fixation. Conclusion: Closed reduction with indirect fixation could successfully be used to manage mandibular fractures in low resourced health facilities, especially in low-income countries. The poor lightening system on roads in Ghana is a major contributory factor to motor vehicular accidents.

In this study, various usage patterns were analyzed after establishing a data mart for micro mobility analysis based on the rental history of public bicycles in Seoul. Rental history data is origin-destination data that includes the rental location and time, and the return location and time. About 1500 rental locations were classified according to the characteristics of the location to create a 'station type' dimension. We also created a 'path type' dimension that displays whether the rental location and return location are the same. In addition, a derived variable called speed, which is obtained by dividing the distance used by the time used, is added, and through this, the characteristics of the riding area and the reason for the rental can be estimated. Meanwhile, administrative district link, administrative neighborhood link, and station type link were created to apply network analysis. Through this analysis, the roles and proportions of administrative districts, public facilities, and private facilities engaged in micro-mobility services were visualized. 49.9% of rentals occur at rental offices near transportation facilities, and half of them occur at rental offices near subway stations. The number of rentals during the evening rush hour is more than double that of the morning rush hour. When the path type is unidirectional, there is a fixed destination, so the distance and time used are short, and the movement speed tends to be high. In the case of round-trip, the purpose of use is exercise or leisure, so the distance and time used are long, and the movement speed is slow. It is expected that the results of the analysis can be used as reference materials for selecting new rental locations, providing convenient services for users, and developing user-specialized products.

The purpose of this study is to identify the direction of future Christian ministry by examining the educational/pastoral ministries of Korean churches during the COVID-19 period. The study used the case study method, where pastors from four different churches were the primary sources of data. Although each church has its own unique ministry, special early morning prayer meetings, family worship services, family Vacation Bible Schools, Bible writing and reading programs, and on-line discipleship training programs were common. In addition, each church implemented special programs that reflected the characteristics and needs of the church, like a talk show, visible radio, surfing meeting, and book-making of Bible manuscripts. Based on these results, ministry programs reflecting the church's pastoral philosophy, strengthening community consciousness, restoring the spiritual function of the family, utilizing online teaching methods, and psychological support for the underprivileged are proposed. In addition, the recovery of Christian publicity and the help from denomination or specialized institutions to develop the programs and online materials were suggested. Through this study, the direction of educational/pastoral ministry in a time of COVID-19 and post-COVID-19 is proposed.

The proper administration of melatonin has well been documented to induce testicular regression in seasonal breeding animals. The subcutaneous injections of melatonin in the afternoon, not in the morning, consistently occurred testicular involution in the male Syrian (golden) hamsters whose reproductive activity is regulated by the photoperiod. But the effects of daily melatonin via gavage have not been estimated. Golden hamsters housed in long photoperiod (LP) were divided into 5 groups: the control animals housed in LP or in short photoperiod (SP) and animals treated daily with low (15 ㎍), middle (150 ㎍), and high dosages (1,500 ㎍) of pure melatonin by using gavage in the evening for 8 weeks. As results, LP control animals had large testes and SP controls displayed small and entirely regressed testes. The animals treated with various dosages of melatonin showed collectively degenerating effects on the weights of testes, epididymides, and seminal vesicles in the middle and high dosage groups, with the individual differences as well. The high dosages induced testicular regression in more proportion than the middle dosages did. The low dosage had large testes like the LP control animals. The small and inactive testes shown in some animals of both middle and high groups presented the complete regression as those of the animals maintained in SP. These results strongly suggest that the administrations of melatonin lead to testicular involution in the male golden hamsters when it is administered through gavage.

Background and objective: The purpose of this study was to comprehensively analyze the user behavior in order to cope appropriately with the increasing demand for mountain usage of those in their 20s and 30s and to allocate resources efficiently. Methods: To analyze the behavior of mountain hiking users, an exploratory data analysis (EDA) was conducted on the data which had been collected in the app Tranggle. The main target are users in their 20s and 30s who visited the mountains in the metropolitan area in 2019-2020. Among them, we have selected data on the top 13 mountains based on the frequency of visits. After data pre-processing, mountain usage patterns were analyzed through statistical analysis and visualization. Results: Compared to 2019, the number of users in 2020 increased 1.36 times. The utilization rate of the well-established hiking trails has also increased. The usage of mountain on weekends (Saturday > Sunday) was still the highest, and the difference in the usage between the days of the week decreased. Outside of work hours, early morning usage has increased and night-time usage has decreased. There was no significant change in usages depending on activity type, level (experience point) and exercise properties. Conclusion: Since the COVID-19 outbreak, the usage of mountains has been changing towards low user density and short-distance trip. in the post-COVID-19 era, the function and role of forests in daily life are expected to increase. To cope with this, further research needs to be carried out with consideration of the wider demographic and social characteristics.

Objectives : The purpose of this study was to investigate the efficacy of Abelmoschus manihot (A-M) on the facial skin by observing the changes in the skin caused by continuous use of the essence containing A-M. Methods : Fifty-one participants were enrolled, 38 were classified as experimental group and 13 were classified as control group. Before the beginning of the test, the skin condition of the participants was investigated with the facial analyzer. An essence containing A-M was provided to the experimental group, and an essence base not containing Abelmoschus manihot was provided to the control group. Participants were asked to use the product in the morning and evening after washing their face. We checked the skin change status every 2 weeks and performed the test 3 times for 6 weeks. Results : In the case of t-zone oil and pores, there was a significant decrease in the experimental group. In the case of moisture, a significant increase was observed in the control group, but the significance was significantly increased when the essence containing A-M was used. In the case of elasticity, it was found that the experimental group continued to increase with the period of use. Conclusion : It is thought that the essence containing A-M will be effective in preventing skin aging through the reduction of t-zone oil, the size of the pores, and the increase in moisture and elasticity.

Objectives : Acne is a common disease that affects more than 70% of adolescents. Acne patients have a poor quality of life compared to patients with other skin diseases. We tried to demonstrate the effectiveness of acne treatment using cleansing soap which is easily used in daily life. Methods : We selected 20 students with acne symptoms on their facial skin. We made herbal Cp (Cold process) soaps using Seosiokyongsan, Kyungohkgo, Hwangryunhaedoktang and Baeksoooh and distributed them to experiment participants. We let them wash their face in the morning and evening for 6 weeks using herbal Cp soap. Prior to the experiment, their skin condition was checked and assessed using A-ONE Smart One-Click Automatic Facial Diagnosis System three times at 3-week intervals. Acne status was classified into 6 stages according to KAGS and acne status was also measured 3 times in total. After the experiment, the changes of skin were analyzed through facial analysis test. Results : Based on the KAGS classification, the condition of acne has improved as a whole. The state of moisture was gradually increased and the state of skin oil was significantly decreased after 6 weeks of using soap compared to before using soap. Conclusions : Cp soaps made from four kinds of herbal medicine are believed to improve the condition of acne by increasing the moisture of the facial skin and decreasing the skin oil content.

Background and objective: This study was conducted to investigate the effect of an agro-healing program on the relationship satisfaction and emotional change between parents and children. Methods: We sent an official letter to D Office of Education with information and recruitment for the agro-healing program. Then D Office of Education has sent the official letter to elementary schools under the jurisdiction to recruit parents who were willing to participate in the programs with their children. The subjects were recruited by order of application, and 27 families participated, but 20 parent-child teams who attended all sessions and fully participated in the program were ultimately selected. From October 12 to November 16, 2019, a total of 6 sessions of the programs were held once a week at a care farm in Gyeongsangbuk-do. In the morning, they participated in a program that utilizes the resources of plants and animals in the care farm, and later participated in an indoor horticultural program in the afternoon. Results: In the parent-child relationship satisfaction test, it was found that communication was significantly increased after participating in the agro-healing program (p = .047). There were no statistically significant changes in the sentence completion tests written by the children, but their potential perception or attitude towards their parents changed more positively than before according to the content of the sentences. Conclusion: The agro-healing program could strengthen the relationship between parent and child by improving the parent-child relationship satisfaction and children's emotional attitude towards their parent.

Objectives : The pores are the openings of sebaceous glands or apocrine glands. They are enlarged by various factors such as sex, age, genetic influence, sebum secretion, acne and so on. When the pores are visually recognizable, they become aesthetically problematic. There are various methods of treating pores, but we have tried to develop a method to reduce pore size by using daily cleanser. Methods : Facial skin examination was performed on 104 students of A university. Among them, 10 persons with large pore size were selected. We surveyed 72 students to determine their subjective skin condition, lifestyle, and washing habits etc. We made herbal fermented soaps using Seosiokyongsan and distributed them to experiment participants. We let them wash their face in the morning and evening for 6 weeks using herbal fermented soap. Prior to the experiment, their skin condition was checked and assessed using A-ONE Smart One-Click Automatic Facial Diagnosis System three times at 3-week intervals. After the experiment, the changes of skin were measured and analyzed through facial analysis test. Results : In our experiment, the early 20s, 9.6% of the students had slightly larger pores. For students with large pores, there was a high likelihood of side effects from using facial products. Using the fermented soap made of Seosiokyongsan, the average size of the pores and the number of large-sized pores were significantly reduced. Conclusion : Seosiokyongsan fermented soap can effectively reduce especially the large size of pores.

Objective : We have reported the effects of Seosiokyongsan (SSOOS) cp soap on increasing skin moisture, decreasing pore size, and reducing acne symptoms on previous studies. But in the case of SSOOS soap, many soap bases were used in the making process. So we could not determine whether the above test results were the effect of soap bases or SSOOS herb medicine. Therefore, We conducted this clinical test to find out the effect of SSOOS itself. Methods : We made two kinds of soap. One type was made of cp soap using only soap bases and gave them to 10 subjects. The other type was cp soap made by adding SSOOS to the soap base and gave them to 25 subjects. The other 10 subjects did not limit the soap. Subjects were asked to wash their face with soap in the morning and evening for six weeks. The test was conducted three times and the results were compared and analyzed. Results : In the test group using the SSOOS soap, the oil in the U zone was significantly decreased and the moisture was significantly increased compared to other two control groups. Pores size and pigmentation were decreased but not significant. There was a significant increase in moisture in the soap base group, but that was a slight increase compared to SSOOS soap. There was no significant results in the without soap control group. Conclusion : SSOOS soap was found to have a significant effect on facial skin as cleansing products.
