Objectives: Myxomatous odontogenic tumors (MOTs) are the third most common odontogenic tumors in the oral and maxillofacial region. Due to its slow-growing, but locally invasive nature, the tumor is usually detected by accident or only when it becomes a large mass, which causes facial deformity. Materials and Methods: Current study reports three unusual cases of MOT including huge myxoma involve the mandible in middle-aged man, MOT with ossifying fibroma pattern in mandible, and MOT in maxilla of young female patient. The diagnosis and treatment strategy of MOTs was also summarized and updated. Results: In reported three cases of patients with large MOTs, surgical treatment was indicated with fibular free flap reconstruction in the mandible and plate reconstruction in the maxilla. The tumors were successfully treated with radical resection and did not show signs of recurrence during the follow-up period. Conclusion: Surgical treatment indication depends on size, the position of the lesion, patient systemic condition and surgeon individual experience. In the case of a large tumor, radical resection and reconstruction is the standard surgical strategy. The conservative surgical treatment including enucleation with wide curettage is still under controversy. The recurrence rate for MOTs is significantly high, up to 30%, therefore long-term follow-up is essential.

Background and objective: Moth orchids in the vegetative stage are suitable for a multi-layer growing environment in a closed-type plant factory which can be a good alternative that can reduce production costs by reducing cultivation time and energy cost per plant. This study was conducted to find out the optimal rhizospheric environment for different irrigation methods without a potting medium and rhizospheric ventilation for the vegetative growth of young Phalaenopsis hybrid 'Blanc Rouge' (P. KV600 × P. Kang 1) and Phalaenopsis Queen Beer 'Mantefon' in a closed-type plant factory system. Methods: The one-month-old clonal micropropagules with bare roots rapped with a sponges were fixed on the holes of styrofoam plates above growth beds, and were watered using the ebb-and-flow (EBB) and aeroponic (AER) methods with Ichihashi solution (0.5 strength) once a day at 06:00 (P) or 18:00 (S), and both (PS). Rhizospheric ventilation (V) was also applied to change the temperature, relative humidity, and CO₂ concentration of the beds. Plants potted into sphagnum moss and watered once a week were used as the control group. Results: After 12 months of treatment, the growth characteristics of the EBB groups were the best among the treatment groups without a medium, but no effect of irrigation timing was observed. V reduced the temperature, relative humidity and CO₂ concentration of the beds. Whereas, EBB+V (ebb-and-flow with ventilation) improved plant growth and reduced the occurrence of disorders and withering. Especially, EBB+V showed a similar performance to the control group. Conclusion: The results indicated that the optimal irrigation method without a potting medium for producing middle-aged potted moth orchids was the EBB system with forced rhizospheric ventilation. Therefore, further studies on the optimal ventilation method and moisture control of the crown need to be carried out to develop the irrigation system without a potting medium for vertical farming in closed-type plant factories.

지역 간 인구이동요인은 개인의 라이프코스에 기인하여 세대별·연령별로 차이가 존재하므로 지역경제성장이 인구이동에 미치는 영향도 연령별로 다를 수 있다. 이에 본 연구는 지역경제성장의 변화가 지역 간 인구이동에 미치는 영향을 연령별로 구분하여 실증 분석하였다. 분석결과를 요약하자면, 첫째, 연령층과 상관없이 지역의 경제성장률과 일자리 증가율의 상승은 순이동률을 증가시키는 것으로 나타났다. 둘째, 청년층은 중장년층에 비해 지역경제성장률과 일자리 증가율이 순이동률에 미치는 영향이 큰 것으로 나타났다. 셋째, 25-29세 연령층은 개인소득수준, 40-64세 중장년층은 지가변동수준의 지역 간 격차가 순이동률에 영향을 주는 것으로 나타났다. 이와 같은 분석결과를 볼 때, 지역 간 인구이동에서 지역경제성장은 여전히 중요한 요인으로 작용하고 있으며, 특히 청년층에게 영향력이 큰 것을 알 수 있었다.

Objectives: The purpose of this study is to report on the efficacy of Korean medical treatment for treating menopausal vasomotor symptoms (heat flashes and sleep disorders). Methods: We treated a menopausal female patient with heat flashes and sleep disorders using Korean medical treatments (herbal medicines, acupuncture, pharmacopuncture, moxibustion, and chuna). To evaluate the results of this treatment, we used Kupperman's Index and the Numerical Rating Scale to measure heat flashes and total sleeping time, respectively. The patient's general health status was evaluated using the European Quality of Life 5 Dimensions Scale. Results: We observed improvements in Kupperman's Index, the Numerical Rating Scale, the patient's total sleeping time, and the European Quality of Life 5 Dimensions Scale following the treatments. Conclusions: This study suggests that Korean medicine may be an effective treatment for menopausal vasomotor symptoms (heat flashes and sleep disorders).

Background and objective: Juvenile crimes tend to intensify and become habitual in South Korea and juvenile delinquencies must be corrected during adolescence. This study aimed to investigate the effects of a forest therapy program on the self-esteem and resilience of juveniles under protective detention. Methods: We designed the forest therapy program titled "A Dreamy Child, One More Forest!" for one night and two days and a total of 122 juveniles under protective detention participated in the program. Self-esteem scale (SES) and resilience scale for adolescents (RSA) were used and the collected data were analyzed using frequency analysis and T-test. Results: Most of the participants were male (96.7%), and the number of those aged 17 years was highest (35, 28.7%). The number of those enrolled in middle and high school was 69 (56.0%) and that of those who dropped out was 39 (31.9%). Their self-esteem significantly increased from 3.102 before participation to 3.636 (p < .001) after participation in the forest therapy program. Resilience also increased remarkably from 2.950 before participation to 3.829 (p < .001) after participation, showing positive changes after participation in both cases. Conclusion: The results indicated the forest therapy program could enhance the self-esteem of juveniles under protective detention, provide them with an opportunity for developing their inner positive power and reinforcomg resilience, helping them return to society in a healthy state. Further research needs to be conducted on how the effects over the program period will differ from one another and how long the positive effects will last.

Background and objective: This study was conducted with 10 men and women in their 50s-60s to investigate the effect of agro-healing activities on the improvement of mental health. Methods: The experimental group participated in total 8 sessions of agro-healing activities, once a week for 2 hours each, at a care farm in Wanju-gun. Physiological measurements were taken with an electroencephalogram (EEG), Salivettes samples, and blood pressure before and after the activities. Results: As a result of analyzing the changes in brainwaves of the experimental group before and after agro-healing activities, relative slow alpha (RSA), relative fast alpha (RFA), and ratio of alpha to high beta (RAHB), the indices of stability and relaxation, increased after the program with statistical significance. Also, the ratio of SMR to theta (RST) of the attention index increased on the right frontal lobes, temporal lobes, and left occipital lobes, and relative low beta (RLB) increasd on the frontal lobes, temporal lobes, and occipital lobes after the program with statistical significance. The sympathetic nervous system activity, which is a stress index, decreased after the program, whereas the parasympathetic nervous system activity, which is a relaxation index, increased, showing statistical significance (p < .05). As a result of analyzing the changes in blood pressure after the program, systolic blood pressure and diastolic blood pressure decreased from prehypertension to normal blood pressure, showing statistical significance. SThese results indicate that participating in agro-healing activities at a care farm for the 50-60s helps reduce stress and improve stability and relaxation as well as attention. Conclusion: Thus, developing and applying customized agro-healing programs for participants will have a positive effect on brain activity and psychophysiological improvement by relieving tension and stress. However, there are limitations in generalizing the results of this study since most of agro-healing farms have low accessibility that leads to a low level of participants.

BACKGROUND/OBJECTIVES: Adolescents who skip breakfast have an increased prevalence of chronic diseases. Thus, we aimed to evaluate whether the intake of rice-based breakfast had positive effects on blood glucose indices and to determine the possibility of diabetes prevalence in Korean youths who habitually skip breakfast. SUBJECTS/METHODS: In this randomized parallel-group controlled trial, 81 subjects who were suitable for compliance among 105 middle-and high-school students aged 12-18 years who usually skipped breakfast were included in this study (rice-meal group [RMG], n = 26; wheat-meal group [WMG], n = 29; general-meal group [GMG], n = 26). The RMG and WMG received a rice-based breakfast and a wheat-based breakfast for 12 weeks, respectively. The anthropometric indices, blood glucose indices, and metabolites were measured at baseline and the endpoint, respectively. RESULTS: The mean body weights in the RMG, WMG, and GMG groups at the endpoint were 62.44 kg, 61.80 kg, and 60.28 kg, respectively, and the mean body weights of the WMG and GMG groups at the endpoint were significantly higher than that at baseline (P < 0.05). The levels of fasting insulin and homeostasis model assessment of insulin resistance (HOMA-IR) values were significantly decreased in the RMG group at the endpoint compared to baseline (P < 0.05, P < 0.05, respectively). The levels of tryptophan and tyrosine in the WMG group at the endpoint were significantly higher than that those at baseline (P < 0.01, P < 0.05, respectively). CONCLUSIONS: Rice-based breakfast has positive effects on fasting insulin levels and HOMA-IR in Korean adolescents who skip breakfast. Additionally, it was found that a skipping breakfast could increase the prevalence of diabetes in adolescents who skip breakfast. Therefore, in addition to reducing breakfast skipping, it is vital to develop a rice-based menu that fits teenage preferences to prevent chronic diseases such as diabetes.
