It was the era, from 1876 to 1910, that some dramatic changes, including an influx of foreign dyes and the beginning of the modern dyeing manufacture, happened in Korea. This paper explores what dyes were sold in the market in this period, who was the main seller of the goods, and how the dyers produced their products. A wide range of natural dye stuffs coexisted with the various kinds of aniline dyes, alizarin dye and synthetic indigo in the market. Coloring materials had been sold by hwapi-jeon, a group of official merchants who acquired a privilege of monopoly from the government. However, the dyes were also traded by sang-jeon and yakguk merchants in the nineteenth century. Most of the synthetic dyes sold in Korea were produced in Germany or in Japan later, and imported in large amount by Chinese, Japanese and German merchants. Yet there also existed Korean merchants and peddlers who sold the goods to the local consumers. Dyers were male and female who belonged to the middle class. They received the orders and payments from the government or merchants. Not only did they dye textiles, threads, cotton, paper and leather, but they also redyed clothes. Indigo dyers were differentiated from other dyers. Modern dyeing manufacture, which was presumably forced to keep pace with the productivity of the weaving process, appeared in the 1900s. It was a branch of the modern weaving manufacture.

It is common for popular products to sell out, and be out of stock. The purpose of this study is to examine the responses of consumers who have experiences of shopping online, and finding their desired products unavailable from being sold out. In order to carry out the study, in-depth interviews were conducted with ten recruits who were recruited from the Internet community, Soul Dresser, which is part of the Korean web portal, Daum. First, the cognitive reaction of the interviewees showed both positive and negative responses when they found out that their desired product was sold out. However, in the case of emotional reaction, all of them showed negative reactions. Observations showed that consumers researched and found similar products including price when they realized that their desired products were not going to be re-stocked. And in cases of similar products not being available, the consumers looked to buy other types of products such as bags, shoes, and other accessories.

This paper deals with two shops dealing with single perishable product the fresh items are sold at a list price in the primary shop and the unsold items that have reached a certain allowed age are transferred to the secondary shop to be sold at a discounted price. It is assumed that the demand rates in two shops are Independent each other and can be expressed as a function of inventory level and price. With the objective of maximizing the profit under a Last-In-first-Out. (LIFO) issuing policy, we develop mathematical models for the following two cases : (1) opening primary shop only and (2) opening both primary shop and secondary shop. There are three decision variables, i.e., the reduced price in the secondary shop, the allowed age at the primary shop, and the order quantities at the primary shop. A solution procedure is developed based on tabu search and its validity is illustrated through a comparative study.

교통수단의 발달과 애완동물 시장의 확장은 외래생물의 국가 간 이동을 증가시키는 주요한 원인이 되고 있다. 게다가 최근 인터넷을 통한 판매는 애완동물 거래를 활성화하는 요인이 된다. 국내의 경우, 외래생물의 수입은 꾸준히 증가하고 있는 반면 수입된 외래생물들이 어떻게 그리고 얼마나 거래되고 있는지는 명확하지 않다. 일반적으로 야생에서 발견되는 외래생물 대부분이 방생의 결과라는 점을 고려하면, 애완동물의 거래 현황을 파악하는 것은 야생으로 유입될 수 있는 잠재적인 외래생물을 파악하는 것과 동일하다고 볼 수 있다. 본 연구에서는 2019년 1월 22일에서 2월 10일까지 총 25개 온라인 펫샵을 대상으로 판매되고 있는 외래 양서파충류의 종수, 빈도, 가격 등을 조사하였다. 조사 결과, 총 677종의 외래 양서파충류가 판매되고 있었으며, 그 중 뱀류이나 도마뱀류를 포함한 유린목(Squamata)이 전체 65.4%(443종)로 가장 많았다. 2019년도 온라인 펫샵에서 판매하는 외래 양서파충류 수는 과거 2015년 공식적으로 수입된 325종 보다 약 2.1배 많았다. 가장 많은 매장에서 판매하는 양서류는 Litoria caerulea(화이트청개구리)(21개 펫샵)였으며, 파충류는 Correlophus ciliatus(크리스디드도마뱀붙)(24개)였다. 외래 양서파충류의 가격은 최저 3천원이었으며, 최고가로 판매되는 종은 유린목의 Rhacodactylus leachianus(리취자이언트도마뱀붙이)의 1억원이었다. 온라인 펫샵에서 판매되고 있는 외래 양서파충류 중 야생에서 발견된 종은 총 11종으로 확인되었으며, 비교적 낮은 가격에 판매되고 있었다. 멸종위기야생생물 II급이자 천연기념물 제453호인 남생이와 생태계교란야생생물인 황소개구리(백색증, albino)가 온라인 펫샵에서 판매되는 것을 확인하였다. 또한 온라인 펫샵에서 판매되고 있는 외래 양서파충류 677종 중 21.6%가 CITES으로 지정된 종이었다. 본 연구의 결과를 통해 국내로 수입되어 판매되고 있는 외래 양서파충류의 현황을 파악할 수 있었으며, 이는 야생으로 유입될 가능성이 있는 잠재적인 외래 양서파충류를 평가하고 예측하는 데 중요한 근거가 될 것이다.

A warranty is a contractual obligation incurred by a producer in connection with the sale of a product. The warranty specifies that producer agrees to remedy certain failures in the product sold. There have been many articles dealing with warranties, but they have studied about optimal warranty cost for the warranty period. In this study, an optimal preventive maintenance time interval is computed. The optimal preventive maintenance time interval minimizing warranty cost for the warranty period is discussed. It is assumed that failure rate is increasing and the failure rate after preventive maintenance or corrective maintenance lies between good as new and bad as old.

The purpose of this study is to analyze the first birthday Hanboks on Internet shopping malls and to find the reason why the costume has various types. From April to May 2012, first birthday costumes were sold on 154 Internet shopping mall sites. On 48 of the shopping malls, traditional Hanboks were sold, on 33 of the shopping malls, fusion Hanboks were sold, and on 73 of the shopping malls, Western formal wear was sold. The percentage of the Hanboks and Western costumes for the first birthday was almost the same. Boys costumes in the traditional Hanbok consisted of 'Magoja, Joggi, Jeogori, and Baji" or 'Baeja, Jeogori, and Baji" with Jeonbok or Sagyusam. Boys' headgear consisted of Bokgun and Hogun. Girls' costumes in the traditional Hanbok consisted of 'Jeogori, Chima' or 'Dangui, Chima or Seuranchima'. Girls' headgear was Gulle, Jobawui, and Baessidaenggi. Boys' costumes in the fusion Hanbok consisted of 'Jeogori, Baji, and Wanggunmo' which is different from the traditional Hanbok in materials, colors, and parts of construction. Girls' costumes in the fusion Hanbok could be divided into 3 different types; a modified traditional skirt, Chima, 'Chima and Jeogori" with new materials and colors, and Western dress with traditional materials. The first birthday Hanboks on the Internet shopping malls are simple and convenient compared to the traditional ones. Furthermore, parts of the costumes are influenced by some popular historical dramas. One of the reasons why the costumes have changed is because the customers have few experiences about traditional Korean costumes and their interests have been affected by the modern media.
