Considerations of how to facilitate aging-in-place(AIP) are becoming increasingly pertinent as care-givers are overwhelmed by an aging population. Aging friendly home-care services combined with IT can satisfy the needs of the elderly suffer from chronic diseases such as depression and dementia. Therefore, we propose future smart phone services and application technologies which can estimate emotional states of the aged and respond to the desire to be happy with mental health, connectedness and consolation from peoples. Firstly, we introduce depression measurement techniques to estimate the severity of depression using multiple sensors. At second, the emotional responding services are categorized to four parts and the details are described. Lastly, we propose the process to implement emotional communication and the application techniques(services) to fulfill the emotional satisfaction and mental healthcare for AIP using smart phone as a mediator.

This research shows how the perception of digital shadow work varies depending on the user's period of use of digital services in applications, which are key areas of digital services. The purpose of this research is to investigate how the digital shadow work type changes over time. This research adopted a qualitative research method for location-based service "help application" users and examined the change in perception from the app service acceptance stage to the app service continuous use stage with two-times interviews of ten users by a longitudinal research design. This study conducted a longitudinal analysis focusing on how digital shadow work occurs in the application subscription process, exploring phenomenologically how the type changes throughout the process over time.

Location Based Services, or LBS refers to value-added service by processing information utilizing mobile user location. With the rapidly increasing wireless internet subscribers and world LBS market, the various location based applications are introduced such as buddy finder, proximity and security services. As the killer application of the wireless internet, the LBS has preconsidered technology about location determination technology, LBS middleware server for various application, and diverse contents processing technology. This paper describes the open architecture for LBS platform ensuring interoperability among the wireless networks and various location-based application services and the functional requirements for the LBS platform. The LBS platform in a narrow sense provides a standard interfaces for location management and network management for location services as follows, positioning (location acquisition through network or/and handset), location managing, location based functions, profile management, authentication and security, location based billing, information roaming between carriers and the system monitoring independent to specific network or ISP/CPs(Content Providers).

O2O service that combine online with offline service has been rapidly increasing and O2O service is the new trend that merges online commerce with traditional markets in various fields. The purpose of this study is to investigate influences of University Student's Perceived O2O application characteristics on O2O services satisfaction and continuous use intention. For this purpose, questionnaires including O2O application characteristics scale, customer perceived O2O satisfaction scale and O2O use intention scale were administered to 241 college students in Seoul. Regression analysis revealed that O2O application Characteristics showed influences of O2O service satisfaction. The O2O application charac*teristics showed influences of continuous use of intention of O2O services, O2O services satisfaction showed partial influence continuous use intention of O2O service. The result of this study is expected to provide implication as an initial study O2O service which is spreading with the growth of mobile ICT. Ultimately, the results of this study provide a number of theoretical and practical implications.

This study aims to evaluate patients' satisfaction with healthcare services in Hawtat Bani Tamim Governorate during the spread of coronavirus. The importance of this study stems from the fact that Covid-19 is challenging countries all over the world. The study adopted a questionnaire for collecting the data. The sample size reached 231 members. The study applied descriptive statistics and inferential statistical methods to obtain the result of the study. The analysis of the data revealed that most of the participants are satisfied with the healthcare services in hospitals and health centers during the Corona pandemic, Health precautions and distancing measures were applied appropriately, Vaccination against corona was available in health centers and easy to access, and rapid response of health care service providers to patients' requests. The participant's opinions showed that the application of Mawid is a suitable method to access healthcare services during Corona, the application is more efficient in providing the required healthcare services and facilitating their access to healthcare services.

The objective of this study was to ,determine trinexapac-ethyl [4-(cyclopropyl- $\alpha$ -hydroxy-me-thylene)-3,5-dioxocyclohexanecarboxylic acid ethyl ester] effects on lodging-related traits of rice varieties treated at different application rates and times. Trinexapac-ethyl WP was applied at the rate of 10, 20 and 30g ai/l0a to Heukjinjubyeo and Daeanbyeo, respectively. Effects of trinexapacethyl varied greatly with application time as well as application rate with little differences between rice varieties. As the application rate increased, lodging index, center of gravity and exsertion of panicle above flag leaf decreased, whereas breaking strength and phytotoxicity increased. Exsertion of panicle was greatly influenced by the application time with a little difference by application rate. The most effective application time of trinexapac-ethyl based on lodging index and total internode length (Ist-4th node) was 2DBH(days before heading) in Heukjinjubyeo and 17DBH in Daeanbyeo, resulting in reducing total internode length by 12.9 and 9.7cm, respectively. A significant reduction was found at the 1st, 2nd, and 3rd internodes in Heukjinjubyeo, while at the 2nd and 3rd internodes in Daeanbyeo. No significant difference was found among treatments in the panicle length of both rice varieties but the panicle fresh weights of Daeanbyeo were significantly greater in all trinexapac-ethyl treatments compared with that of the control when measured 20 days after heading. Consequently, trinexapacethyl treatment significantly improved lodging-related traits of rice plants without affecting rice yield and yield components.

This study was conducted to investigate the effects of boron treatments on flower spike dieback of Statice (Limonium spp.) grown in soilless hydroponic and soil cultures under rain shelter system. The growth of Statice was gradually improved with increasing boron applications in the hydroponics, but not in soil culture with boron treatment as foliar spray or soil application. The degree of flower spike dieback in 6 levels (0, no dieback incidence to 5, very severe dieback incidence) ranged between 0.5 with boron application and 4.4 with no boron treatment. The content of boron in Statice flower spike increased with increasing rates of boron applications in the hydroponics, but the contents of P, Mg, and N were not affected by the boron application. However, K content was highest with no boron treatment. In soil culture, incidence of flower spike dieback decreased with foliar spray or soil application of boron. Therefore, boron application was effective in reducing flower spike dieback and improving cut-flower productivity and its quality, and the recommended rates of boron application were $50{\sim}80{\mu}gL^{-1}$ for hydroponics culture whereas 0.2% borex or ${\geq}0.4kg\;10a^{-1}$ boric acid by foliar spray application for soil culture.

군 통신망 응용서비스들을 위한 트래픽 클래스 분류는 NCW (Network Centric Warfare)를 위한 망자원의 효과적인 관리를 제공하기 위한 주요 요구 조건들 중의 하나이다. 많은 표준들과 기관들에서 트래픽 클래스 구분을 제시하고 있으나, 상용 서비스에 초점이 맞추어져 있고 군 특성을 반영하지 못하고 있다. 더욱이 다양한 군 통신 응용서비스들이 제시되고 있으나, 트래픽 분류에 대한 불분명한 기준에 의하여 기관들마다 서로 다른 분류가 이루어지기도 하고 있다. 본 논문에서는 Y.1541을 기반으로 하는 다양한 상용 표준들과 DoD (Department of Defense)의 제안을 기반으로 군 통신 응용서비스에 트래픽 클래스를 부여하고 전달요구 조건을 설정하기 위한 방법론을 제안한다. 제안 방법은 기존 상용 표준들에서 분류한 트래픽 클래스 체계와 DoD 와 FCS (Future Combat System)에서 제시한 군 응용트래픽 클래스 체계를 대상으로 하여 타당성을 검증하였다. 본 논문에서 제안하는 방법은 기존의 또는 새로운 군 통신 응용서비스에 대하여 기계적이고 일관된 트래픽 클래스 부여가 가능하여, 한정된 군 통신 네트워크 자원을 효과적으로 운용하도록 하는 데에 기여가능 할 것으로 기대한다.
