        Recently, the mineral resource protection policies and regulations in production countries of natural resources including rare metals are becoming more stringent. Such environment makes which market has malfunction. In other word, those are not perfect or pure market. Therefore because each market of natural resources have special or unique characters, it is difficult to forecast their market prices. In this study, we constructed several models to estimate prices of natural resources using statistical tools like ARIMA and their business indices. And for examples, Indium and Coal were introduced.

        Mobile phone market, a market of the device leading the digital convergence as well as positioning itself as one of the national growth driving industry and as a daily necessity, is led globally by companies that have been actively responding to changes in the so-called Smart Revolution environment. Lately, however, the Smart Phone market is prospected to move from growth phase to mature phase by the scholars. In order for a company to proactively respond to the change in such market condition, it is imperative that they ensure absolute advantage in customer loyalty over their competitors by revolutionising the after-sales service(A/S) quality that will lead to service satisfaction. This study aims to configure what dimensions make up for mobile phone A/S quality, and how this quality affects customer satisfaction and loyalty as well as proposing directions for A/S quality improvement by identifying them case by case to see what dimensions have more impact on customer satisfaction.

      • Cortisone이 角膜 上皮細胞 再生에 미치는 影響

        宋朝永,李金姬,宋寅哲 慶北大學校 醫科大學 1958 慶北醫大誌 Vol.1 No.1

        The wide spread use of cortisone in ophthalmology promptly led to questions about the possible deleterious effects of this agent on the healing of wounds in the eye. The authors think that we have already reached the stage of conclusion about the influences of cortisone on the penetrating wounds, corneal vascularization and fibroblastic repair. Nevertheless, some conflicts are yet present about the influence on the regeneration of corneal epithelium. We present the results of our studies on the effects of cortisone on one standard experimental abrasions made in normal rabbits corneas. Cortisone was given by local instillation and subconjunctival injection, and examined the results by histologic study and by fluorescein staining method on the unhealed area. 1. Cortisone administered as drops in the conjunctival sac are innocous on the regeneration of corneal eqithelium in concertrations up to and including 25㎎/㏄. 2. In subconjunctival injection, the cortisone groups showed white subconjunctival areas thought to be cortisone deposits and severe congestion and markedly dilatated vessels. The control groups, showed no white subconjunctival deposits and generally the local reactions were slight. Some delayed wound healing was found in the non-diluted group (25㎎/㏄.). However, in the 1 : 4 diluted solution group, there were no delayed wound healings. 3. When cortisone is used subconjunctivally, one must be careful on the doses, times, and intervals.

        자궁내 피임장치와 동반된 골반 방선균 1예

        이재성,김만조,김진하,이춘관,이세용,송인철 대한산부인과학회 2002 Obstetrics & Gynecology Science Vol.45 No.8

        방선균증은 만성 진행성, 화농성, 무통성의 질환으로 수술전 정확한 진단을 내리는 것은 힘들다. 왜냐하면 골반 방선균증은 다양한 비특이적 임상 증상을 가지기 때문이다. 골반 방선균증은 장기간 자궁내 장치의 사용과 관련이 있으며 복강, 혈행성 파급에 의한 상부 생식기의 이차적인 감염이다. 이 질환의 원인은 그람 양성, 혐기성, 미세 호기성의 박테리아이다. 저자들은 자궁내 장치를 가진 45세의 여성에서 자궁내막 생검시 황과립을 보이는 방선균증이 수술전 진단되어 내과적 치료로 관해를 보이며 추석 관찰 중인 1예를 경험하였다. Actinomycosis is a chronic, progressive, suppurative, indolent disease which appears to be difficult to establish a correct preoperative diagnosis. Bacause pelvic actinomycosis has variable nonspecific clinical manifestations. A cause of pelvic actinomycosis is secondary to the seeding of upper genital tract from other intraabdominal or hematogenous dissemination, especially, ascending pelvic actinomycosis is related to a long time intrauterine device (IUD) inserted state. The causative agent is a branching, gram positive anaerobic or microaerobic organism, not fung. We experienced a case of actinomycosis in IUD user, discovered pathologically on endocervical currettage, thereafter managed with high dose penicillin, followed up with periodic imaging studies.
