Purpose: The study examined the correlation of perceived health status, health behaviors, and marital satisfaction in women who have immigrated to Korea through marriage. Method: Data were collected via questionnaires that investigated health status, health behaviors, Korean language ability, characteristics of couple, and marital satisfaction. Three hundred four subjects were selected for a 4-month period. The data of 300 subjects were analyzed using descriptive analysis, t-test, ANOVA, and correlation, after four questionnaires were excluded due to incomplete data. Results: Perceived health status varied significantly according to nationality, existence of religion, and period of immigration. The scores for perceived health status among women who had lived in Korea for more than 5 years were lower than for women who had resided for 1-3 years. There was a significant positive correlation between health status and health behavior, and health status and Korean language ability, but a negative correlation between health status and age. Conclusion: A program for the improvement of health in immigrant women should include communication assistance as their mother language and should provide periodic health screening.

A real-time processing system for embedded hardware genetic algorithm is suggested. In order to operate basic module of genetic algorithm in parallel, such as selection, crossover, mutation and evaluation, dual processors based architecture is implemented. The system consists of two Xscale processors and two FPGA with evolvable hardware, which enables to process genetic algorithm efficiently by distributing the computational load of hardware genetic algorithm to each processors equally. The hardware genetic algorithm runs on Linux OS and the resulted chromosome is executed on evolvable hardware in FPGA. Furthermore, the suggested architecture can be extended easily for a couple of connected processors in serial, making it accelerate to compute a real-time hardware genetic algorithm. To investigate the effect of proposed approach, performance comparisons is experimented for an typical computation of genetic algorithm.

Nowadays, the computational capability and graphical power based on PCs increase very rapidly every year. As a result, the complicated engineering or scientific problems that could have only been handled by supercomputers a couple of decades ago can now be routinely run on PCs. Besides, the PCs can be assembled in parallel to increase its computational capability theoretically without limitation. The Web-based interface and communication tools are also being enhanced very rapidly and the real-time distance learning (E-Learning) and project cooperation on web get increasing attention. Using the-state-of-the-art computational method, a number of complicated and computationally intensive problems are being solved by PCs. The results can be well demonstrated on screen by graphics and animation tools. Those examples include the simulations of fully nonlinear waves, their interactions with floating bodies, global-motion analysis of multi-unit floating production system including complicated mooring lines and risers. Several examples will be presented in this regard. Also, Web and java-applet based educational tools have been developed at Texas A&M University for better understanding of waves and wave-body interactions. The background and examples of such Web-based educational tools published in Kim et al. (2003) are briefly introduced here.

Researches on air-ground robot cooperating system has been made recently. The cooperation among homogeneous robots focused on the architecture of the system, quality and influence of the communication. In contrast, the cooperation among heterogeneous robots such as aerial vehicle and ground vehicle robots has not been much handled. There are a couple of main points for those air-ground cooperating robots. One is using UAV (Unmanned Aerial Vehicle) as an extra sensor of UGV (Unmanned Ground Vehicle). This kind of application is usually used in situations such as guiding UGV to an appropriate path which could be better determined from the eye in the sky as UAV. The other main application of air-ground cooperating robot system is the localization. By combining sensor information from both UAV and UGV, the robot system as a whole can localize a target object or find features in the environment with better performance than UGV or UAV alone. Although these applications are recently studied in many different ways and devices, there are still a lot of possibilities in the field of air-ground cooperating robot systems. We introduce those research fields in this paper.

The purpose of this study was to investigate the trend of the room where activities of daily living and family events(activities of non-daily living) were performed with time. Research data was collected in 1992 and 2002 from households living in Seoul that have university student by using questionnaire surveys. Data was analyzed using the SPSS package program. The major findings of this study were as follows: 1) Living room was a multi-purpose space for various activities: receiving guests, family communication, ironing, sewing and dining as well as a kitchen. Anbang(master bed room) is the place where the couple sleeps. The room's purpose has changed from a multi-purpose space to a private space. 2) Most of the families performed the majority of the family events in the living room and Anbang. In the past, traditional events and birthday parties were performed in Anbang, but currently the trend has changed. This would mean that with time the majority of the family events were held in the living room. 3) Space planning is required to meet the dwellers' use of living room and Anbang.

The development in the field of the internet of things (IoT) have improved the quality of the life and also strengthened different areas in the society. All cities across the world are seeking to become smarter. The creation of a smart parking system is the essential use case in smart cities. In recent couple of years, the number of vehicles has increased significantly. As a result, it is critical to make the use of technology that enables hassle-free parking in both public and private spaces. In conventional parking systems, drivers are not able to find free parking space. Conventional systems requires more human interference in a parking lots. To manage these circumstances there is an intense need of IoT enabled parking solution that includes the well defined architecture that will contain the following components such as smart sensors, communication agreement and software solution. For implementing such a smart parking system in this paper we proposed a design of smart parking system and also compare it with convetional system. The proposed design utilizes sensors based on IoT and Data Mining techniques to handle real time management of the parking system. IoT enabled smart parking solution minimizes the human interference and also saves energy, money and time.

소위 '인생네컷'이라 불리는 셀프사진관은 MZ 세대의 새로운 놀이 문화로 떠오르며 사용자 수가 나날이 증가하고 있다. 그러나 짧은 시간 내에 다양한 포즈를 취해야 하는 셀프사진관 특성상 촬영이 낯선 사람에게는 여전히 진입장벽이 존재한다. 더불어 매번 비슷한 포즈와 사진 결과물에 기존 사용자는 점차 흥미를 잃어가는 문제점도 발생하고 있다. 이에 본 연구에서는 셀프사진관 사용자의 관계를 분류하는 모델을 개발하여 관계에 따른 적합하고 다양한 포즈를 추천하는 프레임워크를 제안한다. 사용자의 관계를 'couple', 'family', 'female_friend', 'female_solo', 'male_friend', 'male_solo' 총 6 개로 구분하였고 실제 현장과 유사하도록 단색 배경의 이미지를 우선으로 학습 데이터를 수집하여 모델의 성능을 높였다. 모델 학습 단계에서는 모델의 성능을 높이기 위해 여러 CNN 기반의 모델을 전이학습하여 각각의 정확도를 비교하였다. 결과적으로 195 장의 test_set 에서 accuracy 0.91 의 성능 평가를 얻었다. 본 연구는 객체 인식보다 객체 간의 관계를 학습시켜 관계성을 추론하고자 하는 것을 목적으로, 연구 결과가 희박한 관계 분류에 대한 주제를 직접 연구하여 추후의 방향성이나 방법론과 같은 초석을 제안할 수 있다. 또한 관계 분류 모델을 CCTV 에 활용하여 미아 방지 혹은 추적과 구조 등에 활용하여 국가 치안을 한층 높이는 데 기대할 수 있다.

Main machinery in the factory have various digital indicator to display its operating data for the manager. It is useful to control these datum at the remote office for factory automation in order to increase machine productivity. It is easy to use Ethernet infrastructure for remote communication. But most of all machinery in domestic factories still support RS232c or RS485 serial communication way. In this case to control machinery datum on the ethernet base, it is need to change RS232C or RS485 data to ethernet base. In this paper, in order to develop a remote progress management system through the wireless Internet, we show a design method to make easy maintenance by developing the system with both the JAVA language and RxTx Package for RS232c serial communication. For the system implementation, we added the digital indicator connect with a thermo couple to a machine which provide the real time status data of temperature. To connect machines management server program, we set up a convertor to change the RS485 data to the RS232c and also another convertor to change the RS232c data to wireless ethernet.

The aim of this study was to investigate the current state of wife abuse in Seosan and the relationships between wife abuse and the related variables. A total of 132 couples took part in this study. All couples live in Seosan city, range in age from their 20s to 50s and each couple has at least one child. Stratification sampling method was used to select the couples. They were asked to complete self-report questionnaires. Subjects completed a Korean version of the self- esteem scale, marital conflict scale, communication style scale, family history of violence scale, alcohol dringking, and wife abuse scale. In order to examine the current state of wife abuse, such as, frequency, mean, standard deviation and paired t-test, t-test were calculated and analyzed. Next, to identify differences in wife abuse between the upper group and the lower group, t-test was peformed. Finally, to investigate the relative influences of independent variables upon wife-abuse, multiple regression analysis was peformed. All these analyses were conducted using SPSS 10.0 program. The results were as follows; 1) In terms of the current state of wife abuse, there are three main observations. First, $23\%$ of respondents answered that they had beat their spouse or been beaten by their spouse before and after their marriage. Second, compared with physical violence($2{\~}16\%$), other types of violence such as verbal($7{\~}4\%$), emotional($41{\~}64\%$), economical($3{\~}29\%$) and sexual violence($4{\~}38\%$) were reported to occur more often in these relationships. Third, following the abuse most wives tend to tolerate the situation instead of taking an active action like reporting the abuse to police. 2) As for the husbands, subjects that drank a high level of alcohol, blaming and super-reasonable communication style, and family history of violence reported more frequent cases of wife abuse. As for the wives, subjects with high levels of self-esteem, irrelevant communication style, marital conflict, and family history of violence reported having more cases of that abuse. 3) In the case of husbands, alcohol, communication style and family history of violence explained $40\%$ of wife abuse. In the case of wives, marital conflict and family history of violence explained $77\%$ of their experiences with abuse. This study makes the contribution to aims to develop education programs and family therapy relevant to prevent wife abuse and to reconsider the existing laws governing domestic violence in Korea.
