Current-controlled PWM inverter offers substantial advantages in improving motor system dynamics in high-performance ac drive systems under vector control. Among the various current control techniques, fixed band hysteresis current control has been widely used. A hysteresis controller employing sinusoidal bands has been reported in recent years. In this paper new current control schemes based on neural network for PWM inverter are described, Four types of controllers have been studied and their performance compared with each other. Finally, relevant simulation results are shown to prove the effectivness of the proposed current control scheme.

Background: The effectiveness of some therapeutic modalities for cutaneous sporotrichosis may be changed depending on the individual and geographic characteristics, and the clinical type. Itraconazole has been known to be effective for it, however, there have been no standard and ideal guideline on the oral dosage and duration yet. Objective 8: Methods: In this study, we evaluated the effectiveness of oral itraconazole in patients with cutaneous sporotrichosis in relation to dosage and clinical status. The observation of 17 patients with sporotrichosis were made retrospectively, Oral itraconazole was administered at the dose of 200 mg daily in 15 adults over 18 years old and 100 mg in the other 2 children. Results: The duration for healing was within 30 days in 4 cases, within 60 days in 4 cases, within 90 days in 2 cases, within 120 days in 3 cases, and within 150 days of therapy in 2 cases. The average duration in all cases was 12.1 ± 8.6 weeks. Comparison our results to the previous reported one revealed that more shorter treatment time was needed in cases treated with 200 mg daily than that with 100 mg. There was no treatment failure by drug intolerance or resistance. The duration for healing was significantly shorter in the patient groups with prevalence duration more than 5 months, however there was not any significant difference in sex of patients, and the clinical types. The cases with the lesion on the face and cases with fixed type tended to be healed more rapidly than the others, Conclusion: Oral itraconazole may be a safe and effective antifungal agent for the treatment of cutaneous sporotrichosis in a daily dose of 200 mg for 3 months on the average. However, duration for healing could be influenced by the clinical status.

The purpose of this study was to determine the correlation between the awareness and the status of their won oral diseases. A questionnaire survey form was designed to determine the awareness of their won oral diseases and asked aoo of the university freshmen students to fill out the all of questionaries. They were then immediately examined for을 새 determine their status of dental hard tissures by using the WHO criteria. Also determined were the CPITN and the needs for orthodontic as well as prosthodontic treatments. The results were then statistically analyzed to determine the correlation coefficiencies between the awareness and the status of oral diseases by using SPSS statistical package. The results suggested the followings; 1. The correlation coefficiencies between the awareness and the status for number of teeth decayed, missed, and indicated for extractions were 0.18, 0.06 and 0.09 respectively. 2. The correlation coefficiency between the awareness and the status in treated teeth(F component) and CPITN were 0.622 and 0.10 respectively. 3. the agreement between examiners and examinees on the needs for prosthodontic treatments was 87.31% and their sensitivity and specificity were 47.54% and 88.55% respectively. 4. the agreement between examiners and examinees on the needs for orthodontic treatment was 70.40% and their sensitivity and specificity were 77.27% and 60.71% respectively. Data indicate that a majority of respondents are lacking in the awareness of their own oral disease status. Therefore, it is concluded that a regular oral examination, a regular counselling on oral health status as well as specific oral health education for each individual warranted.

최근 온라인 플랫폼을 기반으로 한 소비자의 정보 접근과 기타 상거래의 비중이 점차 확대되는 가운데 각종 온라인 정보통신매체를 활용한 새로운 시장은 급속하게 성장하고 있다. 이러한 온라인광고시장 확대에 따라 온라인광고분쟁 사례들이 증가하고 있으며, 그 해결과정에서의 문제점이 제기되고 있다. 온라인광고에 관한 분쟁은 주로 소상공인 사업자와 광고대행 사업자에 해당하는 사인간의 분쟁으로, 이러한 온라인 광고계약을 체결하는 과정에서 충분한 설명을 제공받지 못하고 있으며, 분야에 대한 이해도 또는 전문기술에 대한 정보의 비대칭성으로 인한 피해가 발행하고 있다. 국내법상 온라인광고 및 온라인광고분쟁해결에 대한 법제도적 정비가 요구된다. 정보비대칭과 관련한 온라인광고 분쟁에서 소상공인이 소비자 범위에 포함될 수 있는지가 문제되는데, 광고를 소비하는 소상공인에게 상대적 약자의 소비자 지위를 인정하는 것이 바람직하며, 이를 뒷받침하기 위하여 「방문판매법」 제3조 제1호 및 그 단서의 개정이 필요하다. 온라인광고분쟁의 경우 재판절차에 의한 소송 전단계적인 온라인광고분쟁조정위원회의 ‘조정’이라는 대체적 분쟁해결제도(ADR)가 마련되어 있으나, 당사자 간 의사합의 및 화해를 권고할 수 있을 뿐 합의된 의무를 이행하도록 강제할 수 있는 권한이 없고 결정내용을 따르지 않더라도 별도의 불이익이 없어, 분쟁의 간이 신속한 해결을 위하여 위원회의 법적 지위와 권한이 강화될 필요가 있다. 한편, 디지털 이행과 함께 갈수록 확대되고 다양해지는 온라인광고시장의 건전한 발전을 위해서는 육성과 보호라는 이해조절적 측면을 감안한 가칭 「온라인광고에 관한 법률」 제정도 고려해볼 시점이다. Recently, in the middle of a consumer access to information and extra commerce based on online platform is getting expanded, the new market utilizing a variety of Online Information and Communications method grows rapidly. In accordance with expansion of Online advertising market, the related dispute cases are increasing and problems arise out of resolving the dispute. Online advertising dispute usually occurs between small business(advertiser) and advertising agencies. A damage to advertisers happens because of an asymmetric information about expertise or having a low understanding of the field. Also, the agencies don’t give a sufficient explanation while making an online advertising contract. So, it required that we need to modify national laws and regimes about online advertising and online advertising dispute resolution. In an online advertising dispute related to Information Asymmetry, it is discussed whether a small business owner can be included in a range of consumer or not. To conclude, it is proper that acknowledges the consumer’s status as weaker party to the owners consuming advertisements and so amending Article 3 (1) and the clause of 「Door to Door Sales Act」 is necessary. Online Advertising Dispute, meanwhile, use Alternative Dispute Resolution(ADR) as ‘Mediation’of Online Advertising Dispute Mediation Committee instead of a lawsuit by judicial procedure. But the Committee can only advise to get to agreement or reconciliation between the two, not have the authority that compel to fulfil the agreed obligations. Even if they don’t abide by the ruling, there is no penalties. In conclusion, it requires to reinforce the legal status and authority of the Committee to get a simple and fast solution. Meanwhile, it is time to consider to make a legislation for sound development of Online Advertising market where it becomes more diverse and bigger with digital transition tentatively named 「Act on Online Advertising」 complementing the aspect of adjusting interest ; growth and protection.

Combining Timber Production and Wood Processing for Increasing Forestry Income: A Case Study of 6th Industrialization in Korean Forestry

Won, Hyun Kyu,Jeon, Hyon Sun,Han, Hee,Lee, Seung Jung,Jung, Byung Heon Institute of Forest Science 2017 Journal of Forest Science Vol.33 No.4

This study was aimed to analyze the increased forestry incomes by combining timber production and wood processing, which is one of 6th industrialization types in Korean forestry. The selected household has been engaged in forestry for two generations and they produce timber and associated wood products in their own facility. The wood products include dimension lumber, interior wood material, cutting board, and cube chips, the household also utilize logging and sawmill residues as well as seed and seedlings as by-products. Incomes and expenses that have been incurred on individual processes of the sequential timber production and wood processing were surveyed, and we analyzed the economic outcomes of entire business. The results of this study indicate that the gross income of the household is 122.3 million Korean won and the net income is 93.6 million Korean won. The net income of the household is approximately 2.8 times higher than the average net income of whole households in the forestry of Korea in 2016, which is approximately 4.3 times higher than that of households that have been particularly engaged in timber production over the country. We found that the 6th industrialization by combining the two sequential processes creates approximately 3.2 times as much added value compared to the case relying on timber production only.

The fatigue characteristics of alumina-glass composites were evaluated by biaxial flexure test under the dynamic loading conditions. 88 specimens were tested by tested by testing 22 samples at each of four loading rates : 0.01, 0.1, 1, and mm/min. A Vickers-produced indentation crack was made at the center of the tensile surface with load of 49.0 N, and the microstructural aspects of crack propagation was investigated under statically loaded state in distilled water at 37℃. The results obtained were summarized as follows; 1. The fatigue parameter of alumina-glass composite containing 6 mol % yttria was n=22.2, σf0=319.6 MPa. 2. 10-year failure stress of alumina-glass composite containing 6 mol% yttria was 171.7 MPa. 3. Fracture surface of alumina-glass composite indicated the frictional interlocking of jogs having the tendency of toughening by crack deflection, rather than by crack bridging.

당사자심판 도입에 대한 소고

양승미,최승원 梨花女子大學校 法學硏究所 2016 法學論集 Vol.21 No.2

Administrative judgments and administrative litigation play an important role as a remedy for the rights of the people. It is a quicker and more convenient remedy than administrative litigation in terms of litigation cost or time cost. I will examine the party Appeals and examine the possibility of their adoption. In the recent amendment to the Administrative Litigation Act, a detailed type of the Party Litigation has been specified. This will also give implications for the study of the parties' referees. It should be fully discussed with other government agencies and functional relationships with the courts should be considered. A general and comprehensive way of introducing the party Appeals or Introducing into the limited field, it should be possible. The Party Appeals can be done by verifying the introduction of it in the Administrative Appeals Act. In the future, the Act should be adapted to the rapidly changing administrative environment. It should design systems in the form of laws and technology convergence taking into account the governance paradigm. On the one hand, the function of administrative judging should be improved, on the other hand, the front-to-back linkage between administrative disposition and administrative litigation should be strengthened. We will have to pursue future predictive legal developments. It is necessary to approach the discussion of introducing the Party Appeals more actively and positively 행정심판과 행정쟁송은 국민의 권리구제수단으로서 중요한 역할을 하고 있으며, 소송비용의 측면이나, 시간비용의 측면에서 행정소송보다 보다 신속하고 편리한 구제절차로서 행정심판이 주목되어 왔다. 본고에서는 행정심판의 유형에 대한 고찰을 통해서 현재 심판 유형으로 규정되어 있지는 않으나, 행정소송법 개정안의 논의에서 지속적으로 중요문제로 제기되어 왔던 당사자소송, 의무이행소송의 행정심판단계에서의 절차에 해당하는 당사자심판에 대해서 살펴보고 그 도입가능성에 대해 검토하고자 한다. 최근 행정소송법 개정안에서는 당사자소송의 세부 유형을 규정하는 등 당사자소송의 활성화에 주목하고 있으며, 관련 논의에 대한 검토는 당사자심판 도입 연구에도 시사점을 줄 수 있을 것이다. 정부의 다른 기관과의 협의를 충분하게 거치고 법원과의 기능적인 관계도 고려하되, 현실적으로 제기되는 국민의 권익구제의 편익을 위해서 처음부터 당사자소송에 대응하여 일반적･포괄적으로 당사자심판을 도입하거나 또는 일단 가능한 종류를 한정적으로 열거하는 포지티브 방식으로 당사자심판의 단계적 입법화를 모색해볼 수 있을 것이다. 향후 행정심판법은 디지털 정보혁명으로 인한 전자정부와 온라인 지식행정으로의 전환이라는 급변하는 행정환경에 적합하도록, 새로운 거버넌스 패러다임을 고려한 법과 기술 융합 형태로의 제도 설계를 해감으로써, 한편으로는 행정심판 기능을 제고하고 다른 한편으로는 행정처분과 행정소송과의 전후방 연계를 강화하는 부단한 미래예측적 법발전을 추구해가야 할 것이다. 이러한 미래변화상을 염두에 둔다면 당사자 심판의 도입 논의도 보다 적극적･긍정적 시각으로 접근해갈 필요가 있다.

원성옥,정승영 현대영미어문학회 2000 현대영미어문학 Vol.18 No.1

The main purpose of this paper is to analyze lexical properties of the syntactic characteristics and the semantic appropriateness of negative polarity items(NPI) in English. In this paper, two different topics of negative polarity items are treated under the following themes : (1) negative implicative(NI) and negative polarity items. All the syntactic properties licensing NPI are related with the semantic validity and c-command theory. Chater 3 has dealt with negative implicative and downward entailment of negative polarity items. The downward entailment and the condition licensing NPI are examined and analyzed in the scope of DE operator. In conclusion, the lexical properties of NPI mentioned above can be specified by the syntactic and the semantic characteristics which are related to NPI in English.
