Hizb ut-Tahrir (HT) is an Islamic social movement that struggles to change the existing political system to the Islamic system. HT argues that all problems in the Muslim world are rooted in adopting secular thought and ideology and the separation between Islam and the state. Hence, HT works to persuade Muslims to abandon that way of life and only apply Islam as the country's only ideology and constitution. HT has spread this narrative since it started in 1953 in Jordan. With this ideological and political attitude, many countries consider HT a threat to their political and community life, suppressing this movement by arresting members and banning the group to reduce or end HT activities in these countries. The Indonesian government has also carried out this repressive policy to limit the influence of Indonesian HTI since 2017. This paper aims to discuss the strategy of Hizb ut-Tahrir to continue its political activities Indonesia after being dissolved by the Indonesian government in 2017. This article used content analysis method to interpret the data collected from interview and documents from Hizb ut-Tahrir. Responding to state repression, HTI sought other methods of action by changing the place of resistance or activities, and by changing its identity.

Contractor's opportunistic bidding behavior refers to contractor's deliberate low-bid, which cannot accord with the cost, and expectation for beyond-contractual reward (BCR), the compensation earned through cutting corners or claims after undertaking the construction project. This research applies System Dynamics to develop a model of contractor's pricing with consideration for dimensions of "cost", "market competition", and "BCR". Iterative computer simulations were performed to analyze the effects of contractor's pricing on the market price. The results were then examined by statistical analysis on data collected from 44 highway projects in Taiwan. It is found that the critical force driving the contractors to bid opportunistically is their excessive expectations in BCR under the current environment. Within the price competition mechanism, if the problem of BCR exists, even if the bidding system is further improved, contractors would still prefer opportunistic bidding behavior, and eventually make the whole construction industry operate ineffectively. Therefore, it is crucial to remedy the aforementioned BCR problem by more effective management policy.

The characteristics of food wastewater treatment in an anaerobic packed bed reactor (APBR) with polyurethane as a packing material and sludge bed reactor (ASBR) was studied. The reactor of 9cm-ID, 150cm-height was fed in a continuous mode from bottom of reactor. For the purpose of constant temperature of reactor, water jacket was installed. The used packing materials was polyurethane sponge foam. Methane which was produced by decomposed organics collected at the top of the reactor for using as a fuel. The substrates used were synthetic, mixed and food wastewater. For the acclimatization of microorganisms, mixed wastewater was used. The major analyses were gas production, COD, pH and volatile acids. Based upon the completed works, the results are as follows: When food wastewater was fed the quantity of produced gas was less than that of synthetic wastewater, but food process saw higher methane content than synthetic process. As well as COD removal efficiency of food process reached at about 85%. In aspect of effluent volatile acid, food process showed low concentration of below 500 mg/l, therefore anaerobic reaction stabled. Conclusively food wastewater used can be digested by anaerobic treatment, especially anaerobic packed bed reactor showed 82% of COD removal, 75% of methane content, 10 l of gas production, and anaerobic sludge bed reactor did 79% of COD removal, 75% of methane content, 81 of gas production at 4 kgCOD/m$^3$day, 36$\circ$C.

Purpose: Most if buildings need various repair works for preventing or delaying the deterioration which gives rise to affect the living condition or function after constructed. Therefore, a long-term repair schedule should be planned and a repair cost is required. In this paper, it aimed at providing the statistical forecast model for a repair cost in roof water-proofing work and elevator work using statistical approach with three variables such as number of household, management area and a elapsed year. Data are collected in apartment housings which are located in Seoul area and conducted with interview and questionnaire sheet. Each analyzed work is divided into a partly work and fully work. Results of this study are shown that, first, the regression model takes a multiplying type like a Cobb-Douglas function and is changed into the log-linear type to include the three variable simultaneously. Second, the goodness-of-fit of the repair cost forecasting model has a good statistics in determinant's coefficient and Dubin-Watson value. Third, the management area is stronger factor than other the number of household and an elapsed year in roof water-proofing work and elevator work.

In order to stabilize the price of fresh ginseng by extension of seasonal variation and marketing structure, and to reduce the cost of production by works of intensive and short term, studies were carried out. As fresh ginseng of 4 years old by the MA (modified atmosphere storage) and CA (controlled atmosphere storage) was stored for 12 week at 4$^{\circ}C$, samples were collected after every 1, 2, 3, 4, 6, 8, 12 weeks for processing red ginseng. Chemical characteristics on ginseng steamed red for the quality evaluation are summarized as follows. The composition of free sugar was consisted of fructose, glucose, sucrose, and maltose in fresh ginseng. And small change was revealed in free sugar composition during the storage period. Glucose and sucrose were largely increased in both treatments of MA (modified atmosphere storage) and CA (controlled atmosphere storage) after 4 week, wherein maltose was decreased. Fifteen different amino acids were identified, and total amount of histamine and arginine were over 40%. Phenylalanine was slightly decreased. As the volatile components in control red ginseng, six different ones including triisopropyl benzene were detected. B-1 ($CO_2$ : $O_2$ : N2=6 : 4.90, DF-100) of CA and E-1 (CPP, DF-100) of MA did not shown triisopropyl benzene as the volatile components. And ${\gamma}$-muurolene, guaiaene, and beta-patchoulene were reduced, but the other components showed the trend of increase.

Drago $Gali{\acute{c}}$ (1907-1992) has been acknowledged as one of most important modern Croatia architects of the 20th century and noted for his controversial apartment buildings at 35-35a and 43-43a blocks on Vukovar Street in Zagreb, Croatia. Although the two housings were highly regarded as the best examples of the post-war housing design in Croatia, a plagiarism controversy arose due to its similar exterior looks to Le Corbusier's $Unit{\acute{e}}$ d'Habitation in Marseille in 1952. This research intends to comparatively analyze architectural features implemented on the works of apartment of Drago $Gali{\acute{c}}$ and Le Corbusier's $Unit{\acute{e}}$ d'Habitation. The analysis focuses on architectural characteristics categorized in three parts: unit plan, community space, and unit combinations. The site survey was carried out to yield more useful information for the analysis. During this process, written and photographic documentations are collected for the further interpretation. In addition, scale drawings are reconstructed for the in-depth analysis of the project.

Simple statistical frequency based analysis, such as Pareto analysis, are widely used in conventional accident analysis. However, due to the dynamic and complex nature of construction works, many factors can simultaneously affect or involve the occurrence of accidents in construction projects. Therefore, the identification of the complex relationship between such factors is important to establish relevant and effective safety management policies and/or programs. In this study, characteristic factors and their relationships' contribution to non-fatal accidents in construction projects are analyzed using the association rule mining (ARM) technique. To this end, a total of 59,202 construction accident data are collected from 2015 to 2019 and the ARM is performed to retrieve specific relationships -named as association rules-among classified factors in the data. Characteristics of the retrieved relationships are analyzed and compared with the results of conventional Pareto analysis. Based on the results, it is found that both fall and trip are notable accident forms having characteristic relations with other factors for non-fatal accidents in construction projects. It is also found that small-scale construction, age of 50s, less than 1 month of working period, and architectural construction are important factors for non-fatal accidents in construction projects.
