기후변화를 비롯한 사회 문제가 심각해지면서 ESG 경영에 대한 인식은 전세계적으로 점점 높아지고 있다. 물류산업은 글로벌 공급망에서 중요한 역할을 담당하는 만큼 물류기업에 대한 ESG 경영 이행이 다양한 사회 구성원에게 요구되고 있다. 한국은 모든 기업을 대상으로 ESG 가이드라인을 마련하였으나, 물류기업 특히 중소·중견 물류기업의 특성을 고려하지 못한 한계점이 있다. 이에 본 연구는 기존 ESG 가이드라인과 대형 물류기업의 지속가능경영 사례, 선행연구 등을 검토함으로써 중소·중견 물류기업을 위한 ESG 경영 진단항목 후보를 정보공시(P), 환경(E), 사회(S), 지배구조(G) 4개 영역으로 도출하였다. 중소·중견 물류기업의 영세기업 특성을 고려한 진단항목을 축소하기 위해 본 연구는 물류기업 종사자 및 학계/연구기관 전문가 총 60명을 대상으로 설문조사를 진행하였으며, 조사결과를 토대로 주성분 분석 방법을 활용하였다. 주성분 분석결과는 정보공시의 4개 항목을 하나로 정의할 수 있으며, 환경은 16개 항목에서 3개 항목으로, 사회는 22개 항목에서 7개로, 지배구조는 20개에서 5개로 정의하였다. 본 연구는 중소·중견 물류기업 특성에 맞는 ESG 경영 진단항목을 제시하는 데에 있어 의미가 있다고 판단이 되며, 향후 유관기관에서의 가이드라인 마련과 중소·중견 물류기업에서의 ESG 경영 추진시 본 연구를 참고할 것으로 기대된다.

Recently, with increasing efficiency of DSC (photo-electrochemical using a nano-particle), The Performance of DSC solar generation system also needs improvement. The approach consists of a Fly-back DC-DC (transfer ratio 1:10) converter to boost the DSC cell voltage to 300VDC. The four switch (MOSFET) inverter is employed to produce 220V, 60Hz AC outputs. High performance, easy manufacturability, lower component count., safety and cost are addressed. Protection and diagnostic features form an important part of the design. Another highlight of the proposed design is the control strategy, which allows the inverter to adapt to the: requirements of the load as well as the power source. A unique aspect of the design is the use of the DSP TMS320LF2406 to control the inverter by current and voltage feed-back. Efficient and smooth control of the: power drawn from the DSC Cell is achieved by controlling the front end DC-DC converter in current mode.

Although the biological potential of gastric epithelial dysplasia (GED) as a precursor of gastric cancer has never been in doubt, the classification of these lesions has been controversial and fraught with marked variations in approach to diagnosis across the world. The complexity of cyto-architectural features has been considered to be of paramount importance for the diagnosis of carcinoma in Japan, while breach of the basement membrane and invasion into the lamina propria has been considered the sine qua non of malignancy and hence a pre-requisite for the diagnosis of cancer in the West. In Korea, although the incidence of gastric cancer is similar to Japan, the diagnostic approach to GED or cancer seems to lie midway between Western and Japanese criteria. In this review, we will discuss the difference in the diagnosis of GED and cancer between two pathologists working in the comprehensive cancer center located in Japan and Korea, one of the most prevalent areas in the world for gastric cancer.

Bimodal Tram is the new conceptual and environmental-friendly public transportation which adopted series hybrid system. The generator driven by CNG engine supplies the electric power to Battery and traction motor. The generator installed on the vehicle will experience the mechanical vibration and electrical transient variation. Those may cause some defects on the generator which will be the hazardous effects to the vehicle. This paper has investigated the possibility to find out some diagnostic features for the defects of generator through the voltage and current generated from it. Those were analyzed in both time and frequency regions. For the next, more works will be needed to complete the purpose of this paper.

Late-onset schizophrenia(LOS) is a controversial entity. It has been thought that onset of schizophrenia is limited to early adulthood, but many European psychiatrists have reported on the occurrence of schizophrenia in late life. DSM-III restricted the diagnosis of schizophrenia to patients with onset of illness before age 45 years. But, DSM-III-R, DSM-IV, and ICD-10 recognize no upper limit to the age at onset of schizophrenia. Patients with LOS have more visual, tactile, and olfactory hallucinations. Patients with LOS have more persecutory delusions, premorbid schizoid personality traits, and less affective blunting. The course of illness was favorable in LOS. We present four cases of LOS. Their detailed clinical features are reported hear with brief review.

As the demand of English education is increasing, the demand for Native English speaking teachers (NEST) is rising, especially in Asian countries. However, due to the low number of NEST, the Korean government is suggesting that Filipino Women be used as English teachers as an alternative. This study aims to answer three questions: (1) are Filipino women in Korea qualified to teach English based on the error analysis of their written essays? (2) what are the linguistic features found in their diagnostic essays? and (3) is their written English better than Korean college students' written English based on the comparison of the two groups? The findings from the Filipino participants show the most frequently occurring errors are related to punctuation usage (commas and hyphens), vocabulary (word choice), verb usage, redundancy, and even as basic as capitalization usage. The results from the comparison of the two groups show that the percentage of the Filipino participants' written error was 14% while the percentage of the Korean participants was 17%. The findings would give us some ideas on the qualification of Filipino women in Korea as English teachers.

In this study, a hardware-independent software scheme is proposed to visualize biomedical signals such as an electrocardiogram(ECG) and their relevant diagnostic features in a real-time mode. To minimize the dependency on a specific hardware units and to maximize software portability into the different hardware platforms, objected-oriented visualization codes are implemented by Visual C++ MFC(Microsoft Fundamental Classes) with the integration of ActiveX modules.

Purpose: To evaluate the clinical and radiographic features of unilateral hyperplastic mandibular condyles for some useful preliminary diagnostic recommendations. Materials and Methods : Clinical records, radiographs and histologic diagnoses of 35 cases with asymmetric mandibular condyles due to apparent unilateral condylar hyperplasia were evaluated retrospectively. Results: Among 35 cases, 28 were true hyperplastic conditions of condyles whereas the remaining 7 were unilateral internal derangement occurring on the short side. 17 of the 28 hyperplastic condyles showed a mass or irregular radiographic shadow with histologic diagnosis including osteochondroma and osteoma. Only 5 of these cases showed facial asymmetry. 2 out of the 17 cases showed hyperplastic round shaped irregular condyles consistent with ankylosis and their histologic diagnoses were osteochondromas. 11 of the 28 cases showed smooth enlargement of condylar head with elongation of the neck causing facial asymmetry, but histologic diagnoses were not available because the surgical operation conserved the condyles. Conclusion: The hyperplastic conditions of the mandibular condyles include not only true hyperplasia, osteochondroma, osteoma, and ankylosis, but also unilateral internal derangement occurring on the short side.

Berberis chitria (family Berberidaceae) has a close affinity with B. aristata, used in traditional systems of medicine as a drug 'Daruharidra' for skin disease, jaundice, affection of eyes, and rheumatism. Keeping this in view, in the present study attempts have been made to identify marker characters of B. chitria in order to differentiate the two species. Some of the diagnostic features of the root are patches of pericyclic fibre, pitted sclerieds and berberine containing cells and heterocyclic medullary rays. Besides, the physicochemical characters such as total ash; acid insoluble ash; alcohol and water soluble extractive; tannins; sugar and starch percentages has shown variations. The percentage of berberine as berberine hydrochloride was also calculated through HPTLC densitometric method and it was found little higher than B. aristata and B. asiatica i.e. 3.16%. Thus, this species can be utilized as a possible substitute to Daruharidra.

Hyuk An, M.D.Atrial myxoma constitutes the most significant of all cardiac neoplasm. About 75% occur in the left atrium and 25% in the right. They may cause severe and progressive disease mimicking valvular heart disease. But recently attention to differential point in the clinical features along with various diagnostic techniques have allowed pre-operative diagnosis in the most cases. From April, `77 to Aug., `78, three cases of left atrial myxoma and one case of right atrial myxoma were operated in Seoul National University Hospital. Pre-operative diagnosis was established with echocardiography and cardiac angiography. In all cases, tumors were resected with cardiopulmonary bypass successfully, and discharged with good results.
