Purpose: This study evaluated the effects of personalized nutrition intervention for increasing hospital meal intake by elderly patients with malnutrition. Methods: The subjects were 30 elderly patients with malnutrition who visited a general hospital located in Daegu. An individual nutrition intervention such as change of meal types or special meal service was given to the patients according to nutrition diagnosis related to inadequate intake of hospital meals. Nutritional intake status of the subjects was assessed by analyzing energy intake, protein intake, index of nutritional quality (INQ), nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR). Results: The causes of inadequate intake in the subjects were poor appetite or preference problems (46.7%), symptom-related problems (30.0%) and mastication problems (23.3%). The INQ of protein in the subjects was significantly increased from $0.81{\pm}0.17$ to $1.41{\pm}0.25$ after the nutrition intervention (p < 0.05). The NAR of protein (before $0.50{\pm}0.21$, after $0.58{\pm}0.17$), iron (before $0.72{\pm}0.30$, after $0.84{\pm}0.29$) and vitamin $B_2$ (before $0.31{\pm}0.16$, after $0.37{\pm}0.14$) was also increased after the nutrition intervention (p < 0.05). The MAR of five nutrients, protein, calcium, iron, vitamin A and vitamin $B_2$, was significantly increased by the nutrition intervention (p < 0.05). Conclusion: Personalized nutrition intervention according to nutrition diagnosis related to inadequate intake of hospital meals may improve the intake amount of elderly patients with malnutrition.

Domestic PCB industry formed by orders of demand companies is extremely vulnerable in its innovation infrastructure including high value-added technology development and information exchange. The majority of PCB products produced in the country relies on the imports from abroad and it causes its vulnerability to external market changes. Due to the negative perceptions about the industry (e.g., 3D job), low treatment (especially SMEs) and expertise employment avoidance in PCB industry, the job market conditions of PCB industry is not so good. In these circumstances, the PCB industry is completely dependent on the demand market such as cellular phones, and tablet PC, and as a result the responsiveness of PCB industry to the changes in demand market is also vulnerable. In this PCB industry, Korean government is trying to build the research infrastructure for PCB industry that realizes the sharing of information among companiesthrough the operation of the PCB industry innovation forum (information innovation), builds SME suppot platform and supports quality improvement (technology innovation), and supports enterprise collaboration processes (material-process-equipment) utilizing PCM open laboratory. The PCB industry technology infratstructure project is going to be promoted by the government(1.3 billion won, each year) and the private investmen(434 million won each year) from 2013 to 2017(5 years project)(table 1). This study analyzes the feasibility of the project, by using the AHP analysis and the results shows that this project is considered feasible because the AHP overall score is evaluated as 0.841, the overall score is greater than or equal to 0.55.

A 3-Dimensional engine in a mobile embedded device is divided into a C-based OpenGL/ES and a Java-based JSR184 which interprets and executes a byte code in a real-time. In these two standards, the JSR184 supporting Java objects uses more processor resources than an OpenGL/ES and thus has a constraint when it is used in an embedded device with a limited computing power. On the other hand, 3-Dimensional contents employed in existing personal computer are created by utilizing advantages of Java and secured numerous users in European market, due to the good quality in contents and extensive service in a commercial network, GSM. Because of the reason, a mobile embedded device used in a GSM network needs a JSR184 which can provide an existing Java-based 3-Dimensional contents without extra conversion processes, but the current version of Java-based 3-Dimensional engine has drawbacks in application to commercial products because it requires more computing power than the mobile embedded device. This paper proposes a binding technique with the advantages of Java objects to improve a processing speed of 3-Dimensional contents in limited resources of a mobile embedded device. The technique supports a JSR184 standard interface in the upper layer to utilize 3-Dimensional contents using Java, employs a different code-conversion language, KNI(Kilo Native Interface), in the middle layer to interface between OpenGL/ES and JSR184, and embodies an OpenGL/ES standard in the lower layer. The validity of the binding technique is demonstrated through a simulator and a FPGA embedding an ARM.

Due to many recent activities on enforcement of the intensified environmental regulation such as the policies of curbing the greenhouse gas and the Restriction of Hazardous Substances (RoHS), the usage of Light emitting diode (LED) has been rapidly increased and energy efficient management of LED light system is regarded as an important technology to enhance the energy efficiency. In this paper, we propose an energy-efficient control scheme of LED light, being composed of multiple light sources. The proposed scheme controls the intensity of LED light source to minimize the total intensity while providing the quality of lighting service. The intensity of light is assumed to be proportional to power consumption, thus the objective is to minimize the total power consumption. A linear programming problem is formulated to find the optimal intensity of each light source and procedure to apply the proposed scheme in the real system is suggested. The performance evaluation results elucidate that the proposed scheme achieves over 20% improvement in power consumption of light intensity in comparison with the conventional dimming control scheme.

This paper presents the window-based permit distribution scheme for efficient medium access control to support multiclass traffic in APON(ATM over passive optical network). The proposed MAC protocol considers the characteristics of QoS(Quality of Service) for various traffic classes. A periodic RAU(request access unit) in upstream direction, includes dedicative request fields for each traffic category within the request slot. The transmission of upstream cell is permitted by the proposed window-based spacing scheme which distributes the requested traffic into several segments in the unit of one spacing window. The delay sensitive traffic source such as CBR or VBR with the stringent requirements on CDV and delay, is allocated prior to any other class. In order to reduce the CDV, so that the permit arrival rate close to the cell arrival rate, Running-Window algorithm is applied to permit distribution processing for these classes. The ABR traffic, which has not-strict CDV or delay criteria, is allocated flexibly to the residual bandwidth in FIFO manner. UBR traffic is allocated with the lowest priority for the remaining capacity. The performance of proposed protocol is evaluated in terms of transfer delay and 1-point CDV according to various offered load. The simulation results show that our protocol has the prominent improvement on CDV and delay performance with compared to the previous protocol.

Purpose : Recently, cancer has become a chronic disease that requires supervision because of early diagnosis and the development of therapeutic technology. As a result, cancer patients are interested in improving the quality of their lives besides the treatment of cancer itself. Therefore, it is necessary to conduct a qualitative research to understand the vivid experiences of cancer patients and structure their treatment experience. Among qualitative researches, grounded theory is developed based on the data collected in the field. The grounded theory research method is easy to analyze for the process and structure of the treatment experience. Therefore, the purpose of this study is to provide basic data on the integrated medical experience of cancer patients Methods : Participants were conveniently selected, and the criteria for selection were for those who had more than 1 month of hospitalization so that they could dictate their situation and experience in a meaningful manner. Data was collected through in-depth interviews and continued until the data were saturated through theoretical sensitivity and continuous comparison methods. The collected data were analyzed through the process of open-coding, axial coding, and selection coding, which are the research methods of grounded theory. Results : Cancer patients differ in their path, purpose, and attitudes depending on their respective situations and the internal and external resources of individuals. There is also a difference in the perception of their situation among the cancer patients and their families. Cancer patients were shown to recognize and cope with problems in the integrated medical treatment process, and have been classified into 6 different types after the results. Cancer patients showed positive changes in terms of physical, emotional, and lifestyle after their integrated medical treatment. Cancer patients perceived the integrated medical treatment process as a horizontal relationship structure and with diversity. Conclusions : The experience of integrated medical treatment of cancer patients is a process of rehabilitation that heals the body and restores life within the interaction of support system, contextual situation, and internal resources of the individual. Despite this, there is a need not only for the efforts of integrated medical service providers but also institutional support in the future with regards to the current weaknesses and points for improvement. In addition, there is a need for an objective criterion to measure the outcome of integrated medicine for the standardization of integrated medical services.

Since Cyber Home Learning is an e-learning system promoted with policy goals of reducing private tutoring costs, solving gaps among regions, and improving scholastic attainments, preceding researches to verify its effects have been developed of evaluation standards focused on achievement of its policy goals rather than educational goals. The evaluation standards suggested in preceding researches have limitations in clearly reviewing Cyber Home Learning's effects by teaching-learning activities factors and Cyber Home Learning's improvement related to teaching-learning activities. Therefore, an evaluation model capable of analyzing effects of Cyber Home Learning from pedagogical aspect is required. The goal of this paper is to design pedagogical evaluation model according to teaching-learning activities factors and analyze effects of Cyber Home Learning. For the goal, researches from Korea and abroad related to Cyber Home Learning have been examined, pedagogical evaluation model was designed according to teaching-learning activities factors, and the model was then experimented through survey and in-depth interview on students who used Cyber Home Learning. It is expected that results of this paper can be used as a basic data to improve quality of Cyber Home Learning service for teaching-learning activities, and will contribute to establishment of more developmental Cyber Home Learning policy in the future.

This study was conducted to evaluate the satisfaction level of interns and residents on training and job environment of two university hospitals in Pusan. The concept of subject's satisfaction was evaluated in general characteristics, socioeconomic status, working condition, human relationship, and job status and scored from 1 to 5. The newly developed questionnaire for this study(32 items) was revised and modified by the preliminary survey. The internal consistency of questionnaire was 0.73(Cronbach's alpha). The self-administered questionnaire was provided to 218 subjects and collected the answering from March 2 to March 25th, 1997, and statistical significances were tested by $x^2-test$, t-test and ANOVA. The satisfaction level between the residents group was significantly different, but satisfaction level of working condition, human relationship and job status showed no difference. The service division part showed highest(2.73) and the surgical division part showed lowest(2.57). The job satisfaction level between the subjects showed higher satisfaction level in working condition, socioeconomic status, and total satisfaction dimension, and intern group showed higher satisfaction level than resident group. Satisfaction level in human relationship dimension, resident group showed higher satisfaction level than intern group, but showed no statistically difference. To improve the working condition for residents, public welfare facilities was firstly suggested and the next was salary increase, overloaded work, respectively. For intern groups, overloaded work and waste work were firstly suggested and the next was public welfare facilities and salary increase, sequentially. The career gets longer, the satisfaction level on general characteristics of working condition, socioeconomic status, and total satisfaction level were increased. The subjects who have religion and higher socioeconomic status showed higher satisfaction level than the other group. The general satisfaction level of subjects in all dimensions showed lower aver age(3.0) and the overall satisfaction level showed below than average. Thus, in order to improvement of subject's working condition, higher quality of life is necessary rather than economic state. In future, these results might be considered to improve the working condition for interns and residents.

Objective : To provide a foundation to develop clinical training program based on a status of sensory integration therapy in Korea identified through the study. Methods : A questionnaire has been developed that is investigating such as environment of therapy, level of knowledge of therapist, and etc. The questionnaire was distributed from June 1st,2014 June 1 to August 31st,2014. The total questionnaire result collected and analyzed are 232 responses. Results : In terms of ratio of therapist who are administrating sensory integration, occupational therapist takes biggest percentage. In most case, it is equipped enough to do treatment in terms of space and tools. Generally, therapists are performing evaluation and documentation earnestly, and willingly participating to continued education and clinical training coursework. However, it is found that some cases are implementing treatment without through evaluation and/or without professional training. Conclusion : This study propose that sensory integration therapists need to train their clinical knowledge and skills through professional training education based on the Ayres Sensory Integration (ASI) theory. Most of professional trainings are administered in capital area currently. The educational opportunities need to be extend to outside of capital region so the level of clinical competence and the quality of the therapy service can be improved.
