This paper proposes an E-Commerce service that supports large quantities of food waste sales generated by collective residences, including apartments, to consumers in urban areas, such as livestock farmers, through online transactions. Unlike general E-Commerce, the proposed service uses a smart food waste bin equipped with an IoT-based sensor and communication module to automatically collect the location information of each apartment and the amount of food waste to be displayed in a specialized E-Commerce platform. The key of this system is to provide information and sell it to consumers. The smart food waste bin periodically delivers its current capacity and location using a weight sensor, GPS sensor and LoRa communication module to a cloud-based database to be used in web or mobile applications. The proposed E-Commerce service is expected to help resolve the food waste disposal problem and revitalize the local economy by linking with a service that delivers food waste from each apartment to a nearby location where the buyer is located.

최근 인터넷 사용 증가는 물론 그에 따른 인터넷 사이트의 증가가 가히 폭발적이라고 할 수 있다. 전자상거래도 인터넷 사용증가에 힘입어 더욱 증가 추세에 있으며 관광산업 또한 예외는 아니다. 호텔에서도 웹사이트를 구축하여 온라인 예약과 각종 서비스에 필요한 정보를 제공하고 있으며 점차 온라인 예약이 증가추세이다. 하지만 인터넷 웹사이트의 급격한 증가는 풍부하고 다양한 정보를 제공한다는 긍정적인 면과 함께 정보과다(information overload)로 인해 정보 검색 등에 많은 시간과 비용이 요구되는 문제를 낳았다. 위와 같은 환경에서 사용자를 대신하여 원하는 정보를 찾아주는 역할을 수행하는 에이전트(agent)의 개념이 도입되었다. 현재 전자상거래 분야에서 활용 중인 에이전트는 구매자가 직접 판매자와 접촉하여 자신에게 필요한 여러 가지정보를 얻고 필요에 따라서는 협상 등을 진행한 후 최종 거래를 성사시키는 ‘사람과 사람간의 일 대 일 거래 과정’중 일부분만을 지원하고 있는 실정이다. 이와 같은 현존 에이전트의 문제점을 보완하기 위해서 구매자와 판매자를 대표하는 에이전트를 개발하고 이들 에이전트간의 직접적인 정보교환, 가격협상 및 이를 바탕으로 한 의사결정까지의 거래 모델을 수립하는 것이 필요하다고 인식된다. 따라서 본 연구는 인터넷상에서 구매자와 판매자간의 거래를 대행하는 인터넷 다중 에이전트(Internet Multi-Agents)의 개발을 위한 개념적 거래 모델을 연구하고, 이를 호텔 예약 분야에 응용하기 위한 각 에이전트의 필요 조건 및 기능을 제시하고자 한다.

Until now, most semantic web service discovery research has been carried out using either Web Service Modeling Ontology (WSMO) or a profile of OWL-based Web Service ontology (OWL-S). However, such efforts have focused primarily on service name and input/output ontology. Thus, the internal information of a service has not been utilized, and queries regarding internal information such as 'Find book-selling services allowing payment after delivery' are not addressed. This study outlines the development of TM-S (Topic Maps for Service) ontology and TMS-QL (TM-S Query Language), two novel technologies that address the aforementioned issues in semantic web service discovery research. TM-S ontology describes the behavior of services using process information and consists of three sub-ontologies: process signature ontology, process structure ontology and process concept ontology. TMS-QL allows users to describe service discovery requests.

The ice machine is the machine for making ice. As most of the companies that manufactures and sells the ice machine are small and medium-sized companies, they have been they have been experiencing the trouble for the after-sales service after selling the machine. The difficulties of the after-sales service are mostly caused by unnecessary customer service requests of the purchaser, which eventually leads to the unnecessary expenditure of the seller and the purchaser. However, financially, the poor ice machine manufacturers want to reduce this cost as much as possible. Furthermore, even if they want to sell their products overseas, they are hesitating because of the after-sales service. For this reason, the companies making the ice machine need a system which checks the status of the ice machine and takes the proper actions without the visiting service. Therefore, this paper introduces the remote control and operational status monitoring systems which can monitor the status of the ice machine in the remote area and control it as needed. Through the developed system, the company manufacturing the ice machine and the manager of the ice machine can understand the current status of the ice machine and respond against the ice machine's trouble, immediately. In addition, it can be expected to have great effects on cost reduction because the maintenance and management after selling can be efficiently performed.

Public Performance in Copyright Law is a wider concept, which people generally think. It includes the presentation of a work to the public by acting, musical playing, singing, narrating as well as even the act of mechanical playing phonogram and cinematographic work. Article 29 in Korean Copyright Act is the restriction of an author's public performance right. It shall be permissible to perform publicly or broadcast a work already made public for nonprofit purposes and without charging any fees to audience, spectators, or third parties, provided that the performers concerned are not paid any remuneration for such performances. Commercial phonograms or cinematographic works may be played back for the public, if no fee is charged to the audience or spectators, except in cases as set forth by Presidential Decree. In recent year, public performance in libraries became a major issue of the Copyright Law. It is a claim that watching cinematographic works in libraries is one of the act that should apply public performance right, thus to use commercial cinematographic works before six months, which was published, need permission to copyright owners. But this claim is unfair because it can make impossible normal library service. Thus there is a need to revise the Copyright Law to understand the difference between act of viewing and public performance in libraries.

The aim of this paper was to study the theoretical background of the convention industry firstly, in which will serve to seek for more efficient plan of promotion. As a result of it, it is found that the convention industry has the characteristics similar to service industry rather than manufacturing, as well as complicated, interdependent ones which are closely related to every field of industries. This paper also considers the advertising, human marketing, and public relations as measures of promoting the convention industry in order to maximize its promotion activities with the characteristics of service industry and establish the plan of promoting the industry. For the effective adoption of these measures in the convention industry, the measures is analyzed by considering the properties and degrees of some convention centers respectively after the strength and weakness of each measure shall be compared. As these measures are mostly shore-run projects, there will be necessary to keep in close touch with other complementary measures in adoption of measures of promotion.

Open Market is one of the key factors to accelerate the profit. Usually retailers sell items in several Open Market. One of the challenges for retailers is to assign categories of items with different classification systems. In this research, we propose an item category recommendation method to support appropriate products category registration. Our recommendations are based on semantic relation between existing and any other Open Market categorization. In order to analyze correlations of categories, we use Morpheme analysis, Korean Wiki Dictionary, WordNet and Google Translation API. Our proposed method recommends a category, which is most similar to a guide word by measuring semantic similarity. The experimental results show that, our system improves the system accuracy in term of search category, and retailers can easily select the appropriate categories from our proposed method.

Recently, U.S. Department of Transportation (DOT) expanded the "Enhancing Airline Passenger Protections" on August 23, 2011 and October 24, 2011. The Rule regulates tarmac delays, denied boarding compensation, customer service plans, and fare advertising. The adopted rule is to protect passengers by improving passenger service requirements on U.S. national or domestic carriers and foreign air carriers as well. The major issues are as follows: First, regarding to so called Tarmac Delay, carriers must establish a Tarmac Delay Contingency Plan setting forth the number of hours the carrier will permit an aircraft to remain on the tarmac at U.S. airports before allowing passengers to deplane. Carriers also must provide passengers with food and water in the event the aircraft remains on the tarmac for two or more hours and must provide operable lavatories and medical attention while the aircraft remains on the tarmac, irrespective of the length of the delay. Carriers also must create and retain records regarding tarmac delays lasting more than three hours. Also they need to update passengers every 30 minutes during a tarmac delay of the status of the flight and the reason for the delay, allow passengers to deplane if the aircraft is at the gate or another disembarkation area with the door open. Second, carriers now must adopt a "Customer Service Plan" that addresses offering customers the lowest fares available, notifying customers about delays, cancellations, and diversions; timely delivery of baggage; accommodating passengers' needs during tarmac delays and in "bumping cases"; and ensuring quality customer service. Third, the new regulations also increase minimum denied boarding compensation limits to $650 / $1,300 or 200% / 400% of the fare, whichever is less. Last, the DOT also has modified its policies related to enforcement of Rules pertaining to full fare advertising. The Rule states that the advertised price for air transportation must be the entire price to be paid by the customer. Similarly, Korea revised the passenger protection clauses within Aviation Act. However, it seems to be required to include various more issues such as Tarmac Delay, oversales of air tickets, involuntary denied boarding passengers, advertisements, etc.
