Basuki Tjahaja Purnama, Jakarta's Ex-Governor, lost his re-election bid in 2017 and then was jailed on a charge of blasphemy. After his defeat, the rhetorics of Indonesian politics was divided into two opposing sides: anti-Communism and 'pribumi' of the radical Islamic movements and Pancasila of the Jokowi administration. Although Islamic political parties are now preoccupied with their own coalitional politics and survivals, rather than solidarity of Islamic forces, the rising Islamic sentiments confirmed by the Jakarta election indicate that religion will continue to be a key variable in Indonesian politics. Meanwhile, ex-military generals who declared themselves as candidates in the 2018 regional election and the 2019 presidential election, as well as a few measures used by the Jokowi administration against extra-parliamentary political opponents, remind us of Suharto's New Order. Steady growth continues in economy. The raise of minimum wage enlarged middle classes and led to a decline of the poverty rate. Jokowi's commitment to building infrastructure has made tangible achievements. Under these circumstances, enhanced cooperation between Indonesia and South Korea is laudable, though any such cooperation must fully incorporate local sociocultural contexts, such as the strengthened halal certification system.

최근, 산업의 발달로 인하여 생활수준이 향상되어 대량생산과 대량소비현상이 발생하고 도시의 밀집도가 높아 단위 면적당 거주하는 인구가 증가되면서 거주지역에서 발생되는 부산물이 현저히 증가되어 환경측면에서 복합적인 환경문제에 직면해 있다. 최근까지 대책마련에 고심하고 있는 도시에서 발생된 다량의 쓰레기 처리문제는 경제적인 측면에서 몇 년 전 까지는 대부분을 매립에 의존해 왔으나, 매립 방식에 의존하였으나 지가 및 공사설비의 상승, 일부 비위생적으로 조성된 매립장에서 배출되는 침출수 및 악취 등의 환경오염이 심각한 사회문제로 대두되면서 매립장의 확보나 증설은 해당 지역주민의 반발로 지방자치단체의 골치 아픈 과제로 등장하였다. 이러한 문제점을 보완하기 위해, 최근에는 매립지 확보의 어려움과 환경보존을 위하여 쓰레기를 정적이고 위생적으로 처리하기 위하여, 소각시설이 표 1과 같이 증가하고 있으나 소각 때 발생하는 다이옥신 등 인체에 치명적인 오염을 유발시키기 때문에 소각로 건설에 대한 환경운동단체와 주민들의 반발이 거세게 제기되고 있는 현실이다. 이러한 영향에 의해 앞으로는 소각보다는 쓰레기 자체를 감량.재사용.재활용하는 처리방식이 표 1과 같이 증가되는 현실이다. 쓰레기를 소각하는 것은 제 2오염을 유발시키고, 소각장 건설비용과 유지관리에 많은 예산이 소요된다. 쓰레기소각장을 건설할 때, 인근주민이나 환경단체로부터 반대의견에 직면하게 되는데, 그 사유는 쓰레기 처리과정의 전 단계인 반입.공급 과정에서 악취발생과, 후단계인 소각설비에서 발생되는 배출가스 오염원을 완전히 제거하라는 것이다. 최근에는 소각장의 설계.시공과정에서 최대한 악취발생과 확산을 억제하는 시설에 투자를 하고 있으며, 또한 주민 편익 시설과 부대 복리 후생시설은 소각시설 주변지역 주민틀의 소각시설에 대한 부정적 이미지를 불식시키며, 외부 방문객이나 운영 관리 요원들에게 쾌적한 환경조성과 업무효율 및 근무환경의 개선에 일익을 담당하고 있다. 본 고는 환경 친화적인 쓰레기 소각장을 설계하는 측면에서 1998년도에 턴키방식으로 발주되었고 2001년 12월에 준공하여 운전하고 있는 경기도 구리시 자원회수시설의 환기설비에 적용된 설계 및 시공개념을 소개하고자 한다.

PURPOSE: This study examined the comparative effects of an ankle sensorimotor training program combined with hip strengthening exercise (ASTPCHSE) and ankle sensorimotor training program (ASTP) alone on muscle strength, static balance, and dynamic balance in individuals with functional ankle instability. METHODS: Sixteen research participants with functional ankle instability were enrolled in this study. The participants were divided randomly into the ankle sensory motor training program group and the ankle sensory motor training program combined with the hip strengthening exercise group. Each group performed a series of exercise programs two times per week for four weeks. The Cumberland ankle instability tool (CAIT) was used to measure the participants' functional ankle instability. A Balance trainer 4 was applied to assess the static and dynamic balance, and a Primus RS multimodal dynamometer was used to evaluate the muscle strength. RESULTS: No significant differences in static balance, dynamic balance, and muscle strength were found between the ASTP and ASTPCHSE groups (p > .05). On the other hand, the dynamic balance and muscle strength improved in the ASTP and ASTPCHSE groups after the intervention (p < .05). The static balance was not enhanced in both groups after the intervention (p > .05). CONCLUSION: Ankle exercise and an ankle sensorimotor training program combined with hip strengthening exercise are effective in improving muscle strength and dynamic balance in individuals with ankle instability. On the other hand, there are no meaningful differences between ankle exercise and ankle and hip combined exercise.

This paper assesses the structural performance of the Daeungbojeon Hall of Magoksa in Gongju, a representative multi-tiered roof traditional timber structure from the Joseon Dynasty, under vertical loads. Employing midas Gen, a structural analysis software, we developed a three-dimensional analysis model closely resembling the actual structure. Static analysis was employed to evaluate the safety and serviceability of the main vertical and horizontal members under vertical loads. While all members met the safety and serviceability criteria, structural weaknesses were identified in the Daelyang of the lower floor, particularly as a transitional beam, necessitating improvement. For the evaluation of dynamic behavior characteristics, eigenvalue analysis was conducted, assuming a relative rotational stiffness of 5% at the main joints. The natural period was determined to be 1.105 seconds, placing it within the category of a Hanok of similar size. The first mode manifested as a translational movement in the forward and backward direction of the building.

Background: This study aimed to determine the effects of static stretching on the pain and range of motion (ROM) of shoulder joints in middle aged women patients with frozen shoulders. Design: One group pretest-posttest design Methods: The participants were 15 middle aged women patients with frozen shoulders in their 40s to 60s. Subjective and objective pain and joint ROM(range of motion) were measured, and the static stretching intervention consisted of 15 minutes of flexion, abduction and external rotation stretching. Results: The results of this study indicated that the daily pain of shoulder joints and pressure pain thresholds of the muscles surrounding the shoulder joints were generally improved after the intervention with the static stretching, for which significant differences were observed (p<0.05). The ROM of shoulder joint flexion, abduction, and external rotation was significantly increased (p<0.05) after the intervention with the static stretching. Conclusion: Static stretching intervention in patients with frozen shoulders relieved shoulder joint pain and had positive effects on the ROM of shoulder joints. Thus, the application of static stretching in middle aged womenpatients who experience severe pain could be effective at enhancing the function of shoulder joints without pain.

The purpose of this study is to validate learning progressions for Earth's motion and solar system from two different perspectives of validity. One is construct validity, that is whether a hypothetical pathway derived from our study of LPs is supported by empirical evidence of children's substantive development. The other is consequential validity, which refers to the impact of LP-based adaptive instruction on children's improved learning outcomes. For this purpose, 373 fifth-grade students and 17 teachers from six elementary schools in Seoul, Kangwon province, and Gwangju participated. We designed LP-based adaptive instruction modules delving into the unit of 'Solar system and stars.' We also employed 13 ordered multiple-choice items and analyzed the transitions of children's achievement levels based on the results of pre-test and post-test. For testing construct validity, 64 % of children in the experimental group showed improvement according to the hypothetical pathways. Rasch analysis also supports this results. For testing consequential validity, the analysis of covariance between experimental and control groups revealed that the improvement of experimental group is significantly higher than the control group (F=30.819, p=0.000), and positive transitions of children's achievement level in the experimental group are more dominant than in the control group. In addition, the findings of applying Rasch model reveal that the improvement of students' ability in the experimental group is significantly higher than that of the control group (F=11.632, p=0.001).

Objectives : This study was designed to investigate the relationship between gastric emptying, psychopathology(especially anxiety and depression), and various factors that can mediate stress and response, such as coping style, social support and level of perceived stress. Methods : A total 30 patients who complained of the non-ulcer dyspepsia and did not have any abnormal finding on the gastroduodenal endoscopic examination, 24 hour ambulatory esophageal manometry and conventional gastroesophageal manometry were tested with gastric emptying that would be a functional examination of stomach. The correlations between the gastric emptying and psychological vaiable such as quantity of perceived stress, Symptom Checklist-90-Revision(SCL-90-R), Beck Depression Inventory(BDI), Spielberger Stait-Trait Anxiety Inventory(STAI), Ways of Coping Checklist and Interpersonal Support Evaluation List were evaluated. Results : 1) The mean and standard deviation of the time for half of the meal to empty(T50%) was $118.50{\pm}23.64$ minute which showed no gastric stasis in terms of gastric emptying test. 2) There were significant positive correlations between T50% and the state anxiety, T50% and thedepression. 3) There was no significant correlation between T50% and the quantity of perceived stress, T50% and mediating factors(coping style and social support). Conclusion : These results suggested that psychopathology, especially emotional components such as depression and anxiety, could affect on the current physiological functional gastric activity(gastric emptying), but quantity of perceive stress and mediating factors of stress and response such as coping style and social support could not affected on the functional gastric activity. These results showed that psychological interventions should considered in management of the patients with functional dyspepia.

The aim of this study was to analyze word frequency effects on eye fixation duration in Korean reading with a one-boundary diffusion model and to show how these phenomena differ between adults (20-28yrs) and adolescents (13-14yrs). We predicted that the drift rate parameter in the boundary diffusion model would reflect the information processing of the fovea during silent reading. Through an eye movement tracking experiment while controlling word properties such as the word frequency and the age of acquisition, Experiment 1 and Experiment 2 show that the information processing pertaining to words to be placed in the fovea is connected to the drift rate of the one-boundary diffusion model parameters. In Experiment 1,in the adult group, the mean difference in the fixation time in the response proportion between the presence of high-frequency condition and low-frequency condition in the adult group was higher in quantile 0.9 than it was in the 0.1 quantile, but in the adolescent group, the mean difference in the fixation time in the response proportion between the two conditions was not significantly in the 0.9 quartile.In Experiment 2, the mean difference in the fixation time in the response proportion between early-acquired condition and late-acquired condition in both groups was also higher in the quantile 0.9 than in the 0.1 quantile. The distribution of the two conditions in the both groups was positively skewed, and the difference showed the same pattern found in the results of Ratcliff(Ratcliff & McKoon, 2008). Based on the experimental results, we propose one-boundary diffusion model as a tool to explain word property effects and individual differences in reading. In particular, we suggest that the drift rate parameter in the boundary diffusion model reflects the information processing of the fovea during reading. In addition, the results show that one-boundary diffusion model can be used to predict the aforementioned phenomena in reading.

Dose distribution throughout the clinical organ range of motion was analyzed using a respiratory-motion simulator that was equipped with a polymer gel dosimeter and EBT2 film. The normoxic polymer gel dosimeter was synthesized from gelatin, MAA, HQ, THPC and HPLC. The gel dosimeter and EBT2 film were irradiated with Co-60 gamma rays that were moved along the x-axis and y-axis in ${\pm}1.5cm$ steps at five-second intervals. The field size was $5{\times}5cm^2$. The SSD was 80 cm and set to 10 Gy at a depth of 2 cm. The PDD at a depth of 50 mm was 75.2% in the ion chamber, 82.3% in the static state and 86.1% in the dynamic state in the gel dosimeter. The penumbra for the dynamic state target, which was measured using the gel dosimeter, averaged 10.89 mm, this is a 40.5% increase over the penumbra of the static state target of 7.74 mm. In addition, when measuring with gel dosimetry, the value for the penumbra is 36.6% smaller in the static state and 29.4% smaller in the dynamic state compared to measuring with film. The aim of this study was to investigate the dosimetric properties of a normoxic polymethacrylic acid gel dosimeter in static and dynamic states and to evaluate the potentiality as a relative dosimeter for dynamic therapeutic radiation.

Purpose: To evaluate the accuracy of a target position at static and dynamic state by using Dynamic phantom for the difference between tumor's actual movement during respiratory gated radiation therapy and skin movement measured by RPM (Real-time Position Management). Materials and Methods: It self-produced Dynamic phantom that moves two-dimensionally to measure a tumor moved by breath. After putting marker block on dynamic phantom, it analyzed the amplitude and status change depending on respiratory time setup in advance by using RPM. It places marker block on dynamic phantom based on this result, inserts Gafchromic EBT film into the target, and investigates 5 Gy respectively at static and dynamic state. And it scanned investigated Gafchromic EBT film and analyzed dose distribution by using automatic calculation. Results: As a result of an analysis of Gafchromic EBT film's radiation amount at static and dynamic state, it could be known that dose distribution involving 90% is distributed within margin of error of 3 mm. Conclusion: As a result of an analysis of dose distribution's change depending on patient's respiratory cycle during respiratory gated radiation therapy, it is expected that the treatment would be possible within recommended margin of error at ICRP 60.
