The prosperity of modern society is heavily depending on communication technology. Communication is now expanding its roles from personal convenience to social/industrial functioning. Photonics was first introduced to communication in longdistance transmission area since it provided wide bandwidth cost-effectively. However, nowadays, photonics is not only a harmonious collaborator with electronics, but has its own exclusive playgrounds in various parts of communication. Limit-zero network pursues a network that can provide abundant capacity and efficiency using very limited resources. Photonics is the most promising candidate to accomplish the goal. In this article, we review the current status and predict the future contributions of photonics to limit-zero network.

People in Korea, a peninsular, have acquired a variety of marine food resources including seaweeds. Ecklonia stolonifera, a brown algae, is commonly dwelling in Korean coasts and their cultivation methods were developed for a mass-production. Recently, studies have revealed that Ecklonia stolonifera is a promising material for the development of health functional foods. In an effort to carefully review the current understating in the effects and mechanisms of Ecklonia stolonifera on liver functions by deduction from relevant literatures, the effective components were identified as phlorotannins, including dieckol, eckstolonol, eckol, phlorofucofuroeckol A, and phlorosterol. Their aiding action on the hepatic functions is categorized as follows. A) Regulation of oxidative stress by anti-oxidant capacity, B) Protection of hepatocytes from toxins, C) Prevention of alcoholic fatty liver and fibrogenesis, D) Regulation of chronic disease by improvement of inflammatory responses and lipid metabolisms, and E) indirect benefit conferred by a personal total wellness.

As RFID technology is becoming ubiquitous, the secunty of these systems gets much attention. Its fields of usage include personal identification, supply-chain management systems, and many more. Many kinds of RFID tags are available on the market which differ both in storage, and computational capacity. Since by standard IT means all the tags have small capacities, the security mechanisms which are in use in computer networks are not suitable. For expensive tags with relatively large computational capacities many secure communication protocols were developed, for cheap low-end tags, only a few lightweight protocols exist. In this paper we introduce our solution, which is based on the least computation demanding operator, the exclusive or function. By introducing two tags instead of one in the RFID system, our scheme provides security solutions which are comparable with those provided by the lightweight protocols. In the meantime, our scheme does not demand any computational steps to be made by the ta.

With the progress of miniaturization and high performance of various sensors, a lot of data is generated in various fields and being collected in real-time, but the use of such large-capacity data is often unable to keep up with the collection technology. In the medical field, health data is collected and managed by platform, which causes inconvenience to users in searching their own health data and receiving medical services. In this paper, in order to solve these problems, we designed and implemented PHDItemReader to improve the speed of data query in a batch application environment that can integrate and process health data having various data expression formats. The experiment compared and analyzed 3 types of query speed based on 1,000,000 hypothetical health data, and as a result of the experiment, it was verified that the PHDItemReader implemented in this paper improved up to about 21% compared to the existing one.

How can we reconcile our aspirations for more economic growth or prosperity with the constraints of a finite planet? One of the high-income countries, Japan, makes us wonder if we can deal with two different challenges simultaneously: overcoming economic recession and solving environmental degradation. This study investigates the supply-side perspective which highlights the productive capacity and efficiency of the economy through economic lenses and the demand-side perspective which highlights the Japanese personal lifestyles through social lenses. This study aims to answer the question, if Japan's sustainable consumption behavior is counter to economic development whilst environmentally proactive. It finds that translating individual practices and cultures of sustainability into the macro- scopic economic growth path is key to a sustainable and healthy Japan.

This study attempted to measure personality changes in collegiate nursing students as a result of their psychiatric nursing practice. The study population consisted of 310 students in 8 colleges of nursing in Korea, 96 with psychiatric practice, 103 with other clinical practice and III without clinical practice experience. The objectives of the study were to identify: 1. The self-actualization scores of nursing students resulting from psychiatric nursing practice. 2. The self-actualization scores of nursing students resulting from other clinical nursing practice. 3. The difference between scores for students with clinical practice experience and those without experience. 4. The relevance between self-actualization and sibling order. 5. The relevance between self- actualization and religion. 6. The coefficiently scores for students before and after clinical practice. The instrument used was the Personal Orientation Inventory (POI), developed by Shostrom. It provides a measure of values and behavior which are thought to be of importance in the development of self- actualization. The main findings of the study were as follows: 1. There was a significant difference in the Time Competence, Self Regard, and Nature of Man scales resulting from psychiatric nursing practice. 2. There was a significant difference in the Inner Directed, Existentialist, Feeling Reactivity, Spontaneity, Nature of Man and Capacity for Intimate Contact scales resulting from other clinical nursing practice. 3. There was a significant difference in the Inner Directed, Feeling Reactivity, Spontaneity, Self- Regard and Capacity for Intimate Contact scales between students with clinical practice and those without practice. 4. There was a significant difference in the Self-Acceptance scale for both the eldest and the youngest siblings. 5. There was a significant difference in the Time Competence, Inner Directed, Existentialist, Self-Acceptance and Capacity for Intimate Contact scales for middle and youngest siblings, 6. There was a significant difference in the Existentialist scale between students with a religion and those without one. 7. There was a significant difference for students without a religion in the Time Competence, Inner Directed, Self-Regard, Nature of Man, and Capacity for Intimate Contact scales after clinical practice. 8. There was a significant difference for students, with a religion in the Inner Directed, Existentialist, Spontaneity, and Nature of Man scales after clinical practice. 9. There was a significant difference for students in the Self- Actualizing value, Spontaneity, Nature of Man and Synergy scales according to whether their parents had a religion or not. 10. Before and after practice, significantly different correlations were found between the Time Competence and Capacity for Intimate Contact scales : the Inner Directed and Existentialist scales ; the Self- Actualizing Value and the Feeling Reactivity, Spontaneity, Self-Regard and Nature of Man scales : the Feeling Reactivity and Acceptance of Aggression scales: the Spontaneity and the Self-Regard and Nature of Man scales; and between the Self-Regard and Nature of Man scales.

The purpose of this study is to suggest implications for maximizing the effectiveness and efficiency of IPP work-learning by studying the effects of the personal characteristics of trainees and firm's field teacher on trainees' employability. The following conclusions were drawn by verifying the causal relationship between factors based on a questionnaire (157 copies) distributed to 200 trainees (learning workers) of 9 universities participating in IPP work-learning training. First, in order to increase the employability of IPP trainees, it is necessary to select trainees with strong core competencies and failure tolerance by verifying individual characteristics of trainees. Secondly, companies should appoint senior staff with strong leadership and teaching capacity as corporate field teachers, and corporate field teacher training institutions should reinforce the training to improve their leadership. Third, work-learning companies should be selected as those with high social integration and absorption capacity, and those companies should try to build an organizational culture of acquiring and learning new technologies. The results of this study are expected to contribute to enhancing the effectiveness of work-learning training by establishing a training system that can systematically select trainees and participating companies and enhance the training capacity of companies and field teachers.

Cooperating with a supplier with professional skills is necessary to achieve performance in the development of the innovative products. It is also important to improve development competence and share knowledge. This study empirically analyzed the effect of participant's Job Competence and Leadership Competence on Knowledge Sharing, and the effect of Purchaser Interdependence on Supplier Absorption Capacity. The purpose of the study is to confirm that Knowledge Sharing between Development Participant and Supplier contributes to Performance and to demonstrate the need for a cooperative relationship with the Supplier. A survey was conducted on the product development participants to confirm the relationship between the factors using a Structural Equation Model. As a result of the hypothesis test, the better the Individual Competence of the development participants, the better the Knowledge Sharing Activity, and then Knowledge Sharing and Interdependence are the main factor in the Absorption Capacity of the Supplier. The results of this study can contribute to improving the Supplier Absorption Capacity in the product development projects in which high technology is converged. In the future, we will study the effects of the project support activities of related departments for Performance.
