This study examined barley sprout powder on the quality and preservation of Sulgidduk. An optimized formulation (moisture 18.2%, barley sprout powder 2.0% and sugar 14.8%) was first obtained, and then the affect if incorporating the barley sprout powder as a raw ingredients in the mixture was evaluated in terms of Sulgidduk shelf life and quality. For comparison, a control Sulgidduk sample was prepared using the optimized formulation exclusive of the barley sprout powder. After preparation the samples were stored for 3 days at $20{\pm}1^{\circ}C$. The moisture contents of both samples slightly decreased during storage: however there was no significant difference between the samples. Both samples had decreases in colorimetric L- and a-value attributable to the addition of the barley sprout powder as well as storage. Furthermore the treatment sample had increases in yellowness due to the addition of barley sprout powder and storage while the control sample had decreases in yellowness throughout the storage period. The treatment sample had increasing textural hardness, gumminess, and chewiness as the storage period increased. Finally, the treatment sample had a higher total microbial count for aerobes at the beginning of storage: however, as the storage period progressed the control had greater microbial levels. In conclusion the overall results indicate the addition of barley sprout powder has a preservaion effect on Sulgidduk. This data is expected to contribute to the commercialization of high-quality Sulgidduk products with added nutrition and extended shelf life.

According to the popular use of the multimedia services in distributed environments, the need for the variable multimedia communication technologies have been presented today. In order to support the efficient transmission multimedia streams, the multicasting, and the interoperability between multimedia applications in distributed environments, the development of the open exclusive multimedia communication systems and the provision of the control and management methodologies for media streams have been required. In order support the realtime transmission of multimedia stream in distributed environments. the protocols such as RTP, RSVP, and RTSP have been standardized. For supporting the interoperability between multimedia applications and the control and management of streams, the distributed processing platforms such as CORBA by OMG and DSM-CC by DAVIC were published. In this paper, we introduce the CORBA-based distributed multimedia communication system which support the realtime transmission, control, and management of multimedia streams and provide the interoperability between multimedia applications. Finally, we present the QoS measurement results by the interoperability between our systems and VoD systems.

A lighting control switch, extended to incorporate a power line communication technology, is developed. The system uses not an exclusive microprocessor but a general one, and developed PPM protocol. The coupling circuit is a type of an isolation LC filter, and the impedance of the circuit was designed as low as possible to extend signal transmission distance. The frequency of the carrier, considering the data length and signal attenuation as the length of power lines, was set at 250 kHz. Tests on a prototype in an indoor power lines have shown that the switch has a stable operation with the distance of power lines

A workflow process (or business process) management system helps to define, execute, monitor and manage workflow models deployed on a workflow-supported enterprise, and the system is compartmentalized into a modeling subsystem and an enacting subsystem, in general. The modeling subsystem's functionality is to discover and analyze workflow models via a theoretical modeling methodology like ICN, to graphically define them via a graphical representation notation like BPMN, and to systematically deploy those graphically defined models onto the enacting subsystem by transforming into their textual models represented by a standardized workflow process definition language like XPDL. Before deploying those defined workflow models, it is very important to inspect its syntactical correctness as well as its structural properness to minimize the loss of effectiveness and the depreciation of efficiency in managing the corresponding workflow models. In this paper, we are particularly interested in verifying very large-scale and massively parallel workflow models, and so we need a sophisticated analyzer to automatically analyze those specialized and complex styles of workflow models. One of the sophisticated analyzers devised in this paper is able to analyze not only the structural complexity but also the data-sequence complexity, especially. The structural complexity is based upon combinational usages of those control-structure constructs such as subprocesses, exclusive-OR, parallel-AND and iterative-LOOP primitives with preserving matched pairing and proper nesting properties, whereas the data-sequence complexity is based upon combinational usages of those relevant data repositories such as data definition sequences and data use sequences. Through the devised and implemented analyzer in this paper, we are able eventually to achieve the systematic verifications of the syntactical correctness as well as the effective validation of the structural properness on those complicate and large-scale styles of workflow models. As an experimental study, we apply the implemented analyzer to an exemplary large-scale and massively parallel workflow process model, the Large Bank Transaction Workflow Process Model, and show the structural complexity analysis results via a series of operational screens captured from the implemented analyzer.

Purpose - This study examines the effect of control-ownership wedge on stock crash risk. In Korea, controlling shareholders have exclusive control rights compared to their cash flow rights. With increasing disparity, controlling shareholders abuse their power and extract private benefits at the expense of the minority shareholders. Managers who are controlling shareholders of the companies tend not to disclose critical information that would prevent them from pursuing private interests. They accumulate negative information in the firm. When the accumulated bad news crosses a tipping point, it will be suddenly released to the market at once, resulting in an abrupt decline in stock prices. We predict that stock price crash likelihood due to information opaqueness increases as the wedge increases. Research design, data, and methodology - 831 KOSPI-listed firm-year observations are from KisValue database from 2005 to 2011. Control-ownership wedge is measured as the ratio (UCO -UCF)/UCO where UCF(UCO) is the ultimate cash-flow(control) rights of the largest controlling shareholder. Dependent variable CRASH is a dummy variable that equals one if the firm has at least 1 crash week during a year, and zero otherwise. Logistic regression is used to examine the relationship between control-ownership wedge and stock price crash risk. Results - Using a sample of KOSPI-listed firms in KisValue database for the period 2005-2011, we find that stock price crash risk increases as the disparity increases. Specifically, we find that the coefficient of WEDGE is significantly positive, supporting our prediction. The result implies that as controlling shareholders' ownership increases, controlling shareholders tend to withhold bad news. Conclusions - Our results show that agency problems arising from the divergence between control rights and cash flow rights increase the opaqueness of accounting information. Eventually, the accumulated bad news is released all at once, leading to stock price crashes. It could be seen that companies with high control-ownership wedge are likely to experience future stock price crashes. Our study is related to a broader literature that examined the effect of the control-ownership wedge on stock markets. Our findings suggest that the disparity is a meaningful predictor for future stock price crash risk. The results are expected to provide useful implications for firms, regulators, and investors.

On 12 July 2016, China's maritime claim to most of the South China Sea (SCS) based on the so-called nine-dash line was rejected by the Arbitral Tribunal, constituted under Annex VII to the UN Convention on the Law of the Sea (UNCLOS) concerning issues in the South China Sea including the legality of the so-called "nine-dashed line", the status of certain maritime features and their corresponding maritime entitlements, together with the lawfulness of certain actions by China which the Philppines, in a case brought in 2013, alleged were violations. As having the Tribunal determined that China's claim had no legal grounds in UNCLOS, thus undermining China's claims, and establishing that China has no exclusive legal rights to control the area roughly the size of India. There are some major implications from the Tribunal's ruling in the Arbitration award. These include implications on: how to delimit the maritime boundary in disputed waters, how to promote maritime confidence-building measures, how to safeguard maritime safety and security, and how to promote the rule of law in the SCS. Since its application of UNCLOS in East Asia, it has been obvious that the only way to resolve maritime disputes in the region is to build strong maritime cooperative partnerships under the auspices of the rule of law.

A recent High Court's decision regarding the withdrawal of life supporting medical treatment (artificial ventilator) from an elderly female patient in the terminal stage has opened up a new era of the "euthanasia dispute" in Korea. With this decision, the legitimate withdrawal of life supporting treatment became possible under certain conditions and the Korean Medical Association is working toward the establishment of practical guidelines for the terminal-stage patients. However, there are still very few debates on the cases of pediatric patients in the terminal stage or suffering from fatal diseases. For pediatric patients, the core principle of autonomy and following procedure of "advance directives" are hardly kept due to the immaturity of the patients themselves. Decisions for their lives usually are in the hands of the parents, which may often bring out tragic disputes around "child abuse", especially in Korea where parents have exclusive control of the destiny of their children. Some developed countries such as the U.S.A., the U.K. and Canada have already established guidelines or a legal framework for ensuring the rights of the healthcare system regarding children suffering from severe illness, permitting the withdrawal of Life supporting medical treatment (LSMT) in very specific conditions when the quality of life of the children is severely threatened. For the protection of the welfare and interest of the children, we should discuss this issue and develop guidelines for the daily practice of pediatricians.

Tourism is often considered as one of the main industries to promote development and modernization in small South Pacific islands countries. In Fiji, this was recognized in the 1960s, and resulted in large-scale resort based tourism development in coastal areas. While tourism has obvious advantages to the economy, a lot of problems such as exclusive foreign control of the main hotels and resorts, considerable overseas leakage of earnings, the limited participation by indigenous resource owners, and localized environmental damages to reefs and mangroves are emerging. For sustainable tourism development, it is needed to set growth objectives and targets for tourism in terms of benefits to Fiji, and to concentrate support on 'Rural Tourism' such as community-based tourism that have lower leakage and put more into local economies. Through case study in this paper, to develop rural tourism at the local level, several recommendations are as follows: 1) to introduce various rural tourism programs such as experiencing Fiji's traditional culture, participating in activities, picking fruits and harvesting agro-products, 2) to enhance aggressive promotion and marketing strategies, 3) to build the capacity of local communities for improving the quality of tourism services, and 4) to provide the infrastructure for tourism business such as road accessing, water supply and disaster prevention.

Purpose - This study involves the following questions: "Does internalization theory fully explain reality?" and "Which additional factors may add extra value to the theory?" To answer these, this study divides market entry mode into two steps, initial and subsequent and then, focuses on the subsequent distribution step; that is, the post-entry strategy after initial entry. In addition, this study relies on finding strategic orientations that affect the decision of post-entry into foreign markets. Research design, data, and methodology - To investigate this, this study examines 252 cases of Korean online games for each foreign market and the distribution mode at the product-team level. Results - The result shows that companies use different distribution strategies as a post-entry mode, like licensing, or joint distribution rather than exclusive distribution, through subsidiaries even if they already have wholly owned local subsidiaries which have enough experience and resources to select the entry modes among various types and then provide full commitment and control. Additionally, it finds that strategic orientation affects post-entry strategies differently. Conclusions - Therefore, this study is noteworthy and significant, as it practically extends the existing theories such as an internalization and distribution for decision making regarding the overseas expansion of entertainment businesses.

This study compares and analyzes the supporting system used in Korea and Japan to facilitate the development of maeul-mandeulgi supporting systems. And the results of comparison and analysis are as follows: First, it needs to establish the separate legal system in the city planning system and to enact the local more local autonomous ordinances to complementarily connect with the administrative system. Second, an exclusive department should be organized under direct control of the local government head. Third, the maeul-mandeulgi support center should hire the full-time employees including the experts and civil officials who are not relevant with administrative works, and the local administrative organization should lead the operation of this center while strengthening the functionality of the center to be suitable with the local situations. Fourth, it is necessary to diversify the way to proceed with the maeul-mandeulgi project, and to look for a source of financial resource instead of depending on the budget of the administrative organizations.
