Seasonal adjustment is useful to provide a better understanding of underlying trends in Korean economic statistics. The seasonal component also includes calendar effects such as Seol and Chuseok. Most popular seasonal adjustment methods are X-12-ARIMA of the U.S. Bureau of the Census and TRAMO-SEATS of the Bank of Spain. Statistics Korea and the Bank of Korea compile seasonally adjusted series of several Korean economic statistics. This paper illustrates basic principles for seasonal adjustment and the current status of seasonal adjustment in Korea based on previous research. In addition, several issues on seasonal adjustment are addressed.

This study aimed to explore the methods to provide life service for hinterland villages, which is the biggest function of the seat of myeon in rural areas, and enhance central functions/roles. This study also aimed to provide basic information to establish a direction of the future projects of the seat of myeon through empirical study on the comprehensive improvement projects of the seats of eup and myeon and related demanders' perception for sustainable rural area. Based on the results, a variety of hardware manuals are correspondent with present rural situations in the comprehensive improvement projects of the seats of eup and myeon. Therefore, community-based welfare facilities should be expanded. Also, village infrastructure facilities and village landscape projects should be promoted to improve pedestrian environment. Finally, switching into an ecological environment project should be considered to improve village environment as well as supply energy saving facilities.

Purpose - This paper examines the "Arrangement Concerning Mutual Assistance in Court-ordered Interim Measures in Aid of Arbitral Proceedings by the Courts of the Mainland and of the Hong Kong Special Administrative Region" (the Arrangement), which became effective on October 1, 2019, calling on courts of mainland China and Hong Kong for reciprocal commitment in support of court-ordered interim measures in aid of arbitral proceedings. Because the Hong Kong courts have granted interim measures in aid of arbitral proceedings seated in and outside of Hong Kong even prior to the Arrangement becoming effective, this paper focuses on the significance of the Arrangement making Hong Kong the first and only seat outside of mainland China from which parties to arbitral proceedings may successfully obtain interim measures to preserve of assets, properties, and/or evidence from Chinese courts to be enforced in China. Design/methodology - The significance of interim measures in international arbitration and the existing circumstances of interim measures in support of international arbitral proceedings in mainland China and Hong Kong are discussed first in this paper. Due to the confidential nature of arbitral proceedings, while the details of applications for interim measures pursuant to the Arrangement cannot be discussed, in examining the implications of the Arrangement, the relevant and necessary information was made available from the Hong Kong International Arbitration Centre, as it is one of the six qualified arbitral institutions under the Arrangement. Findings - This groundbreaking Arrangement provides a mechanism for parties with China-related matters to more effectively resolve their disputes, the opportunity for Hong Kong to become an unparalleled seat of arbitration, and for mainland China to overcome some of its negative perceptions in international arbitration. Because the Arrangement also allows parties to directly apply for interim measures from mainland Chinese courts, parties with China-related matters should take note of this potential bypassing of the procedural hurdle, which usually requires an arbitral institution to submit such applications in China, and make strategic decisions accordingly as may be appropriate. Originality/value - Because the Arrangement is a recent yet a significant agreement calling on courts of mainland China and Hong Kong for reciprocal commitment in support of court-ordered interim measures in aid of arbitral proceedings, this study will provide useful guidance for parties with China-related matters all over the world, especially in light of China's rapid economic growth and extensive and prominent trade relationships in today's world. Parties who foresee the need for interim measures from mainland Chinese courts should designate Hong Kong as their seat of arbitration and select one of the six qualified arbitral institutions under the Arrangement to administer their arbitral proceedings in order to benefit from the Arrangement.

In this paper, we propose a new safety system composed of wearable devices, driver's seat belt, and integrating controllers. The wearable device and driver's seat belt capture driver's biological information, while the integrating controller analyzes captured signal to alarm the driver or directly control the car appropriately according to the status of the driver. Previous studies regarding driver's safety from driver's seat, steering wheel, or facial camera to capture driver's physiological signal and facial information had difficulties in gathering accurate and continuous signals because the sensors required the upright posture of the driver. Utilizing wearable sensors, however, our proposed system can obtain continuous and highly accurate signals compared to the previous researches. Our advanced wearable apparatus features a sensor that measures the heart rate, skin conductivity, and skin temperature and applies filters to eliminate the noise generated by the automobile. Moreover, the acceleration sensor and the gyro sensor in our wearable device enable the reduction of the measurement errors. Based on the collected bio-signals, the criteria for identifying the driver's condition were presented. The accredited certification body has verified that the devices has the accuracy of the level of medical care. The laboratory test and the real automobile test demonstrate that our proposed system is good for the measurement of the driver's condition.

As the number of objects connected to the Internet increases rapidly, intelligent device development projects are gradually expanding that provide direct value to humans, away from simple monitoring functions, including sensors and communication functions, or delivery to servers.It is expected that the device will develop a technology that analyzes surrounding sensing information and changes the surrounding environment in consideration of users' preferences or safety. By establishing a biosignal measurement system in a developed product that can bring various effects using air, it will be possible to grasp the user's condition through a pattern of change in pressure distribution when seated. This paper proposes a construction system that enhances the comfort of using an air car seat through contact between a temperature measurement sensor and a user, and enables effective management of measured biosignals by linking them with an air pump control system.

Purpose: Recently, there has been a movement to guarantee the right to watch sports for the disabled. However, the sports stadium is designed without considering the wheelchair users, so the right to move in the stadium is not secured. Restrictions on the movement of the disabled make the evacuation vulnerable in an emergency. This study aims to develop a plan to ensure the safety of movement and evacuation of wheelchair users by conducting simulations targeting indoor sports stadiums. Method: The simulation was performed by constructing a scenario with the shape of the stands as a variable. The effect of the installation of wheelchair seats on evacuation was confirmed. Result: The results according to whether wheelchair seats are installed, the evacuation route of wheelchair movement, and whether wheelchair seats are separately arranged were compared. The impact of wheelchair seat installation on evacuation and its characteristics were derived. As a result, upward and separation seat was the most vulnerable to evacuation. Conclusion: A plan to secure evacuation performance was derived for the top floors of upward and separation seat. It is judged that the content can be use as a way to secure the safety of movement and evacuation of the disabled in sports stadiums.
