  • This paper presents a new method of parity storing for ECC(error correcting code) in SSD (solid-state drive) and suitable structure of the controller. In general usage of NAND flash memory, we partition a page into data and spare area. ECC parity is stored in the spare area. The method has overhead on area and timing due to access of the page memory discontinuously. This paper proposes a new parity policy storing method that reduces overhead and R(read)/W(write) timing by using whole page area continuously without partitioning. We analyzed overhead and R/W timing. As a result, the proposed parity storing has 13.6% less read access time than the conventional parity policy with 16KB page size. For 4GB video file transfer, it has about a minute less than the conventional parity policy. It will enhance the system performance because the read operation is key function in SSD.

  • Smart phone users prefer fast reading and texting. Hence, users frequently use abbreviated sequences of words and phrases. Nowadays, abbreviations are widely used from chat terms to technical terms. Therefore, gathering abbreviations would be helpful to many services, including information retrieval, recommendation system, and so on. However, manually gathering abbreviations needs to much effort and cost. This is because new abbreviations are continuously generated whenever a new material such as a TV program or a phenomenon is made. Thus it is required to generate of abbreviations automatically. To generate Korean abbreviations, the existing methods use the rule-based approach. The rule-based approach has limitations, in that it is unable to generate irregular abbreviations. Another problem is to decide the correct abbreviation among candidate abbreviations generated rules. To address the limitations, we propose a method of generating Korean abbreviations automatically using sequence-to-sequence learning in this paper. The sequence-to-sequence learning can generate irregular abbreviation and does not lead to the problem of deciding correct abbreviation among candidate abbreviations. Accordingly, it is suitable for generating Korean abbreviations. To evaluate the proposed method, we use dataset of two type. As experimental results, we prove that our method is effective for irregular abbreviations.

  • Along with economic growth in the 1970s, the nation's economy, railroads, and airports have soared, but the facilities have been aging for 30 years. The aging SOC lowers the national competitiveness and threatens the safety of the people. SOC is a key asset of the national life and economic activity, and is a key factor for evaluating the national competitiveness. Therefore, it is necessary to systematically manage and operate the SOC related to people's lives. In the USA, the SOC report card is issued regularly. Those reports are used as a basis for securing budgets. In Korea, facilities management institutions are different. Therefore, there is no integrated SOC monitoring system. Hence, this study developed a 'SOC information system' that can collect reports scattered throughout the country and support report cards. The demonstration system was implemented through the web and the feasibility of implementing the evaluation support system was confirmed. The collection distributed SOC data should be supported by national policy. Although it takes a long time, it is necessary to improve national competitiveness and public safety.

  • The purpose of this study is to empirically analyze whether performance-oriented remuneration systems in public thermal power generation companies substantially induces organizational commitment of employees, and contributes to organizational performance. According to the study, adequacy of salary and individual work evaluation have significant effects on organizational commitment, whereas external and internal evaluations for pay-for-performance remuneration systems do not have a significant effect. Annual salary for performance and pay-for-performance systems have a significant influence on organizational performance. In addition, because annual salary and individual work evaluation of the performance-oriented remuneration system have significant effects on both the indirect effect, through organizational commitment, as well as the direct effect on organizational performance, there exists a partially mediated effect on organizational commitment. Conversely, because external and internal evaluations do not significantly affect organizational commitment, there is no means of verifying the mediating effect. Studies suggest that a fair annual salary system for performance employed in conjunction with a pay-for-performance system will provide positive impacts on organizational performance and employee loyalty.

  • "Borderless village" is a kind of alternative social project to build a multi cultural community of migrant workers around Wongok-Dong, Ansan leaded by Ansan Migrant Center since 1999. We thought this project deserved attention from a view point of social sciences for such reasons as follows. (1)This project could give an opportunity for us to examine the concrete effects of globalization on local areas and responses of these areas to those ones. (2)This project was composed of theoretical concepts very similar to those of reflexive modernization theory. So by examining this project we could have a chance to judge the validity of the latter. (3)The process of making discourses on this project was very interesting. It looks like more democratic and constructive one than others. (4)This project proposed the problem of creating a new form or way of social movement different from so called 'old or new social movements.' Our provisional conclusion of this study was this project could be estimated as very creative and progressive one but it was too abstract to be realistic and effective yet.

  • Purpose : The purpose of this study is to compare the growth pattern of breast fed and formula fed infants in the first 1 year of life. Methods : Anthropometric data(weight, length, head circumference) of at birth, 1, 3, 6, 9 and 12 months were collected by chart review and characteristics of subjects were collected by questionnaires. Among 358 infants, breast fed infants were 161(84 males, 77 females) and formula fed infants were 90(42 males, 48 females). Neither group was given solid foods before 4 months. The weight for age, length for age and head circumference for age were calculated. Breast fed infants were separated into 2 groups(breast fed for 4-11 months and breast fed for more than 12 months). Results : Characteristics of infants and mothers were similar in both groups except for maternal age. Mean weight of breast fed group was lower than that of formula fed group at 12 months of age(male : P=0.004, female : P=0.004). However, mean weight of 12 months breast fed group was below formula fed groups weight at 9 and 12 months(P<0.05). Mean length and head circumference were similar between groups. Conclusion : The growth indices of breast fed and formula fed infants are similar at birth, but weight curves of two groups differ in the first 1 year.

  • As the prevention of dementia is more important than the treatment after the onset, attention has focused on the prevention of dementia in the elderly. For this study based on 11 integrated programs, we analyzed the domestic research trends of dementia prevention programs for the elderly from 2000 to 2018 in the study of Yang Su-gyeong, Ko Bo-sook, and Park Jeong-hwan (2019) We reviewed the literature research on the elderly's dementia prevention program centered on play. By activity type, music, language, and physical activity were 4 (40.0%), respectively, and games, art, and work were 3 (30.0%), respectively. Dance, literature, traditional play, and recreation were 2 (20.0%), and yoga and life were 1 (10.0%), respectively. In this study, for the purpose of exploring the possibility of using the contents of early childhood education in the elderly dementia prevention program, play shows very positive aspects such as physical exercise ability, positive emotions, and emotional characteristics for the elderly. It is considered that if dementia prevention programs are developed using the contents of early childhood education for the elderly, they will be able to utilize leisure time positively while providing continuous services and maintaining group experiences and mental health.

  • While there is no evidence for parafoveal processing in alphabetic languages such as English and Finnish, there is some evidence that morphological information is processed in syllabic languages like Chinese. Korean writing system, Hangul, would be able to provide morphological preview benefit effects since it is an "alphabetic syllabary" which contains both alphabetic and syllabic features. This study explored morphological parafoveal preview benefit effects during reading Korean using irregular verbs, which have phonological and orthographical differences between fundamental and conjugated forms. In the Experiment, the target word was irregular conjugated form, and there were four preview conditions: identical (e.g. 구워), fundamental form (e.g. 굽다), orthographically related (e.g. 굼다), and unrelated control (e.g. 죨어). In the result of study, identical was shortest and morphological, orthographical, unrelated preview were followed. Moreover, measures of first-pass reading of morphological preview were significantly shorter than those of unrelated control preview. This results support the hypothesis of morphological preview benefit effects in Korean. The implications of the results are discussed.

  • In this paper, we have designed and developed a middleware for an effectively approaching database to the existed brain disease clinical research system. The brain disease clinical research system was consisted of two parts i.e., a register and an analyzer. Since the register collects the registration data the analyzer yields a statistical data which based on the diverse variables. The middleware has designed to database management and a large data query processing of clients. By separating the function of each feature as a module, the module which was weakened connectivity between functionalities has been implemented the re-use module. And image data module used a new compression method from image to text for an effective management and storage in database. We tested the middleware system using 700 actual clinical medical data. As a result, the total data transmission time was improved maximum 115 times faster than the existing one. Through the improved module structures, it is possible to provide a robust and reliable system operation and enhanced security functionality. In the future, these middleware importances should be increased to the large medical database constructions.
