This article aims to describe the institutional structuring strategy of independent smallholders in accelerating sustainable economic development, by taking the example of the cow-coconut integration system (SISKA) problem in Sialang Palas Village, Riau. The method used identified stakeholders related to SISKA; the stakeholder's goals and interests, farmers' social and institutional bases, and self-help farmer socio-economic networks. First, identification of various factors through strengths, weaknesses, opportunities, and threats (SWOT) analysis techniques. Second, through the Modern Political Economy analysis technique. Third, imparting knowledge and skills to the farmers and village officials through a collective learning process in utilizing natural resource waste and social resources. The results showed that the farmer management strategy in the reform era started by clustering the interests of farmers. The dynamics of structuring group relations between the chairman and members with farmers outside the group are the basis for strengthening the local ideology of independence in the future. This institutional structuring strategy that focuses on access to farm power in the village decision-making process encourages a more integrated work of farmer organizations. The analysis above shows that the independent smallholder institutional engineering through regulation, organization, and resources are determined by the farmer household economic factors and the application of the value of local wisdom.

When a workpiece is to be arc welded around the outside corner, continuous welding without welding seam in the neighborhood of comer still remains a very difficult technique. Skilled welders weld comers by delicate“hand-eye coordination”while turning the workpiece manually, However, there is not a very clear solution to this problem in robotized arc welding process. In order to solve this problem, the coordination of a robot and a positioner with one or two axes is necessary. This paper presents a method of continuous welding around the corner of workpiece using the coordinated motion of a robot and a positioner. The positioner is either revolute jointed or prismatic jointed. In this paper, a clothoid curve is chosen for welding trajectory. The clothoid curve is excellent in connecting straight and curved weld-lines with good continuity and accommodates various welding conditions. By using this welding trajectory, the deceleration, which leads to widening of the melt and the heat affected zone, at comer area is reduced with strategic rotation of robot torch in coordination with a positioner providing smooth transition of welding torch orientation. Two types of special clothoid curves are developed for different weld slope conditions. These clothoid curves are applied to the case of linear and rotary Positioners at arc welding robot work-cell.

Providing visual field for a driver is one of the most important things for safe driving. Therefore, it will be a first step fur the safe driving that the driver recognizes front and back outside scenes within short time in the car. Specially, it is essential to take the visual field in frequently foggy area where the traffic accident can cause highest rank in the number of deaths. In this paper, our technique can provide the visual field by displaying the location of neighboring vehicles on the monitoring system, embedded board navigator in the car, using the location information of the vehicles from GPS(Global Positioning System) in real time. It is expected that this system can contribute to help safe driving and to lower collision accidents by guiding to cope with unexpected circumstances.

The purpose of this paper is to examine and analyse the features of plan type and space composition of the Siheyuan(courtyard house) which is one of the most remarkable types of the traditional dwellings in China. With the passage of time this house developed into one of the chinese house style. The technique of Siheyuan's spatial composition goes so far back in the New Stone Age. The relics of this are the colony layout, the system of four sides, the layout type of a palace, the picture of lacquered ware, the pictured brick, the earthenware of house type, the cave painting, the paintings of painters and others. The fundamental spatial conception of it arranges one or more courtyards to compose, sometimes in a very complex way, a general walled compound. The main longitudinal axis is mainly north-south, but the chief buildings, or halls are always placed transversely to it. These rectangular buildings mayor may not connect, by means of open galleries variously planned, with rows of smaller buildings flanking the courtyards on both sides. On this system, enlargement is never carried out by adding to height, but by continual duplication of existing units, and growth in breadth or preferably depth. The need for family security is thought to have led to the development of this rectangular houses with walls mainly blank on the outside, defensible entrances, and public service facilities in the center of the houses.

This study is a basic experiment on quality management of the compression strength of high strength concrete, aiming. at quality management of high strength mass concrete by giving the temperature hysteresis of the mass test pieces to managerial test pieces. Different from ordinary concrete, high strength concrete generally shows the temperature high rising caused by hydration heat inside the concrete. It is known that, in mass concrete, thermal stress occurs due to the difference in temperature between the inside and the outside, which causes a significant difference in compression strength between structure beams and managerial test pieces. It is also reported that there is a large difference between the compression strength of cylindrical managerial test pieces of standard underwater curing and the strength of structure beam concrete. Thus, this study made concrete test pieces in an optimal mix ratio for each strength level, and also created thermal insulation curing box and managerial test pieces. Then it carried out comparative analysis in relation to core strength and suggested equipment and a technique that can control the strength of high strength concrete mass more conveniently and accurately.

The objectives of this study are (1) to describe the changes in the tourism industry that have occurred due to COVID-19; (2) explain the adaptation strategies of tourism industry stakeholders to maintain the resilience of Tanjung Puting tourism destination during the COVID-19 pandemic, and (3) explain the government's strategy in supporting tourism industry stakeholders to maintain the sustainability of Tanjung Puting tourism destinations during the COVID-19 pandemic. This is qualitative research; data was collected through in-depth interviews and the collection of published documents or information related to the Tanjung Puting tourism destination. The data analysis technique used in this study was interactive analysis. The results of the study found that the COVID-19 pandemic caused the tourism industry to experience dormancy, tourism stakeholders who lost income, switched to other sectors and looked for other alternative jobs. Tourism workers are currently doing jobs outside the tourism sector to survive, but when tourism is running normally, will return to their main jobs. The strategy undertaken by the government is to build resilience at the meso level, focusing on tourism destinations. The findings of this study suggest that tourism industry players are required to be creative and innovative in facing this pandemic.

In the present paper, we study the entropy analysis of boundary layer flow over a slender stretching sheet under the action of a non uniform magnetic field that is acting perpendicular to the flow direction. The effects of viscous dissipation and Joule heating are included in the energy equation. Using similarity transformation technique the momentum and thermal boundary layer equations to a system of nonlinear differential equations. Numerical solutions are obtained using the shooting and fourth-order Runge-Kutta method. The expressions for the entropy generation number and Bejan number are also obtained using a suggested similarity transformation. The main objective of this article is to investigate the effects of different governing parameters such as the magnetic parameter ($M^2$), Prandtl number (Pr), Eckert number (Ec), velocity index parameter (m), wall thickness parameter (${\alpha}$), temperature difference parameter (${\Omega}$), entropy generation number (Ns) and Bejan number (Be). All these effects are portrayed graphically and discussed in detail. The analysis reveals that entropy generation reduces with decreasing wall thickness parameter and increasing temperature difference between the stretching sheet and the fluid outside the boundary layer. The viscous and magnetic irreversibilities are dominant in the vicinity of the stretching surface.

The use of public Wi-Fi has increased in recent years with many people like to spend their time outside in malls or café shops which provide public Wi-Fi for their customers. However, since the public Wi-Fi can be accessed from any device the security of public Wi-Fi plays a big role to prevent the stealing of information by an attacker with methods and techniques such as WPA, WPA2 and WPA3. However, it is well known to the attackers that these methods are not difficult to get hacked by the attacker device to take the client precious information. Some researches were done in increasing the security of public Wi-Fi each with their own different technique or algorithm to provide more secure connection to the public Wi-Fi and prevent any unauthorized user to connect to avoid stealing the data of another legal user. Theses research paper are evaluated to learn which method excel in protecting the public Wi-Fi security by giving an analysis to the methods provided by the research paper with comparing the pros and cons of each algorithm. Moreover, the research displays that there are methods to actually provide security to the public Wi-Fi with each being very different in implementation.

Nigeria is a country with multiple ethnic groups; as a result, English language is used as a lingua franca to enhance information flow. Despite this, the Indigenous languages of communities are mostly used for interactions, even in university environments thereby affecting smooth interaction for those who do not understand them. This study therefore investigated the impact of being a linguistic outsider on information access, learning and social wellbeing of students. Descriptive research of a case study was used for this study. The population for this study consisted of non-Yoruba indigenous students. Judgmental sampling technique was used to select 50 non-indigenous students; structured interview was used. Results showed that Yoruba indigenous language was used lightly in the classroom and heavily outside the classroom, with mixtures of pidgin and English languages. It was found that being a linguistic outsider had a negative influence on information access. However it was not a total dependent factor to social wellbeing of students who desire for their various languages to be predominantly used and for them to enjoy equal benefits with Yoruba indigenes. This study also revealed that being a linguistic outsider does not have negative influence on academic learning. It was recommended that the stakeholders in university management promote the complete use of English language in the classroom while students should be encouraged to interpret Yoruba language when spoken in the midst of non-indigenes.

Acoustic emission (AE) is one of the most powerful techniques for detecting damages and identify damage location during operations. However, in case of the source location technique, there is some limitation in conventional AE technology, because it strongly depends on wave speed in the corresponding structures having heterogeneous composite materials. A compressed natural gas(CNG) pressure vessel is usually made of carbon fiber composite outside of vessel for the purpose of strengthening. In this type of composite material, locating impact damage sources exactly using conventional time arrival method is difficult. To overcome this limitation, this study applied the previously developed Contour D/B map technique to four types of CNG storage tanks to identify the source location of damages caused by external shock. The results of the identification of the source location for different types were compared.
