상악동에 발생한 粘液膿瘤腫 : 1예보고 A Case Report

김수홍,김경식,양원용,전태준,백세민 中央醫學社 1983 中央醫學 Vol.45 No.4

Mucocele involving the paranasal sinuses are commonly occurring lesions. The literature shows that the frontal, ethmoid, and sphenoid sinuses are most frequently involved, in that order, whereas involvement of the maxillary sinus is relatively rare1. Mucopyocele, mucocele in which the mucous secretion has become purulent, are less common in the maxillary sinus. The following case report is of interest because of the relative rarity of this destructive infla-mmatory process in the maxillary sinus and because, as in this patient, the lesion can sometimes be confused with a malignant neoplasm.

In this paper, LC output filters are designed to reduce output harmonics and harmonic analysis are performed. Generally, multilevel inverters are used in high power application and operates with low switching frequency, which, in turn, generates large output harmonics. Output filters are used to reduce output harmonics. The design approach to reduce output harmonics of the 3level multilevel inverter is discussed and DSP(TMS320C31) is used for the digital control of the system. the design example is given. The designed system is verified by simulation and experiment. 본 논문은 단상 멀티레벨 인버터의 LC출력 필터 설계와 변조비에 따른 고조파 분석을 수행하였다. 일반적으로 고전력 응용에 적합한 멀티레벨 인버터는 낮은 스위칭 주파수하에서 구동되므로 출력단에 큰 고조파 성분을 포함하게 된다. 이를 감소시키기 위해 출력단에 필터를 삽입하는 방법이 효과적이다. 3레벨 NPC 멀티레벨 인버터의 출력단 고조파를 감소시키기 위한 필터 설계 방안을 검토하고, 디지털 제어 방식을 위해 DSP(TMS320C31)를 사용하였다. 또한 필터의 설계예시를 보였고, 설계된 시스템의 타당성을 시뮬레이션과 실험을 통해 입증하였다.

(Background and Purpose) The content creator market, through online platforms, has begun to develop into a new culture. New media content activities in various fields strongly influence society. Several commercial systems that generate revenue from content creator activities have increased, and a new media market has developed over several years. Among them, fashion companies and creators spread content and stand out. However, small companies, startups, and single-person companies have poor working environments owing to a lack of equipment, marketing platforms, and space constraints. Although a shared space has already emerged to solve this problem, co-working spaces for the professional working environment of fashion designers are rare and expensive due to high entry barriers. Therefore, this study aims to investigate and analyze co-working space cases that can support fashion creators' work, from content production to online marketing, to derive space to supplement improvements. (Method) First, we examined the online marketing trends and business status of fashion creators. Second, we looked at the work of fashion creators and found spaces to support their work activities. Third, the concept and current status of the co-working spaces were investigated, and the spatial composition of the co-working spaces were identified through previous studies. Fourth, a co-working space in which a filming studio is formed is selected to conduct a case study. Fifth, a space for fashion creators, confirming the possibility of support is provided. Finally, the spatial components and characteristics were analyzed for a smooth working environment for fashion creators. (Results) As a result of examining the spatial characteristics of the four co-working studios—independent offices, multi-type offices, conference rooms, and phone booths—OA zones were supported as basic spaces. However, an open office was used with the lounge because the nature of the space was not clear. Office spaces that are more open than necessary blur the purpose of the community and work spaces. There was a big difference between service and work support space, and it was found that it did not support spaces where fashion creators could collaborate and market. (Conclusions) There is an urgent need to improve the open office space where companies and creators collaborate to meet the purpose of the co-working space. Furthermore, a filming studio, a marketing space that supports collaboration with companies, a sample room that can match models or coordinate products, and a fitting room, are needed. If there is space to support fashion content creators' activities by improving the co-working spaces, the spread of the new media market will become new competitiveness with the growth of the fashion industry.

디자인 프로세스에서 콘셉트의 시각화를 위한 [CMS]모형 제안

김수홍 한국기초조형학회 2019 기초조형학연구 Vol.20 No.5

Many designers and students recognize the importance of design concepts. However, when designing, design concepts are not set correctly, and design concepts are often only used formally. As a result, design results that are not related to the concept of design are derived, and the design imitated is prevalent. Therefore, this study helps to understand design concept by grasping role and component of design concept. And, it aims to present concept model for visualization of design concept. The scope of the study was limited to the design visualization process, and the meaning of the design concept within the design process was examined. As a research method, Chapter 2 examines the current status of value-oriented design through the background of the times, and derives the premise that “design is the choice of value”. In chapter 3, we analyzed the concept of design concept and the precedent research of design process, and analyzed the current state of design practice and educational field. In addition, three elements, “Concept-Motive-Style,” which are found in the creative field, were derived. And the [CMS] model was derived by constructing the relationship between Concept, Motive, Style. In Chapter 5, the [CMS] model was applied to the design process of good design cases to prove its usefulness. And the usefulness was verified. In the design process, 'visualization of the concept' is a process that many students find difficult because it depends on the ambiguity of the concept itself and the subjectivity of the designer. The [CMS] model compensates for formal ambiguity while maintaining content openness. So it is meaningful in that it helps to understand the concept and makes it easier to visualize the concept. 많은 디자이너와 학생들이 디자인 콘셉트의 중요성을 인식하고 있지만, 디자인 프로세스를 진행할 때 콘셉트를명확하게 설정하지 못하는 것은 물론, 콘셉트를 형식적으로만 사용하는 경우가 적지 않다. 이런 현상으로 인해콘셉트와 상이한 디자인 결과물의 도출이나 모방중심의 디자인이 만연한 실정이다. 따라서 본 연구는 콘셉트의의미와 역할, 그리고 콘셉트를 이루고 있는 구성요소를 파악함으로써 콘셉트에 대한 이해를 돕고, 디자인 개념의 시각화를 위한 콘셉트 모형을 제시하는데 목적이 있다. 연구범위는 디자인 콘셉트의 본질적 의미가 아닌 프로세스 상에서의 의미를 고찰하였고, 디자인의 조형적 측면인 ‘시각화 프로세스’로 한정하였다. 연구 방법으로는 2장에서 시대적 배경을 통해 가치중심의 디자인 현황을 살펴보고, ‘디자인은 가치의 선택’이라는 전제를 도출하였다. 3장에서는 디자인 콘셉트와 디자인 프로세스의 선행연구를 분석하고, 디자인 실무와 교육현장의 현황을 분석하였다. 그리고 창작분야에서 공통적으로 나타나는 ‘Concept-Motive-Style’의 세 가지 요소를 도출하였다. 4장에서는 이 요소들의 비교와 의미 재규정 및 관계구성을 통해 콘셉트 모형인 [CMS]모형을 도출하였다. 5장에서는 [CMS]모형으로 우수디자인 사례의 디자인 프로세스에 적용해 봄으로써 유용성을 검증하였다. 디자인 프로세스에서 ‘개념의 시각화 과정’은 콘셉트 자체의 모호성과 더불어 디자이너의 주관성에 의존하는 영역이므로 많은 학생들이 어려워하는 과정이다. [CMS]모형은 콘셉트의 내용적인 개방성은 유지하면서 형식적인 모호성을 보완하여, 콘셉트의 이해를 돕고 개념의 시각화를 쉽고 명확하게 했다는 점에서 의의가 있다.

Background : Iron deficiency is the most common cause of anemia worldwide. It is well known that iron plays an important role in the metabolism of many bacterial species. A reduction in immune competence by iron deficiency or iron excess might lead to an increased susceptibility of the host to infection. Investigations have been reported of alterations in the cell-mediated immune response in iron deficient human patients. Confounding variables in clinical studies, such as additional nutritional deficiencies, pre-existing infection or other concomitant disorder, make it difficult to conclude that iron is the only causative factor in immune alteration. In this study, we investigated the change of the cell-mediated immunity in iron deficiency patients. Method : Twenty four patients with uncomplicated IDA were included in this study. The blood levels of hemoglobin, RBC indices, serum ferritin, serum iron, and TIBC were measured. The indices of cell-mediated immunity such as CD3, CD56 and NK cell activity were measured. The indices of cell-mediated immunity were compared with each hematologic mean group. The correlations between hematologic indices, iron parameters and the indices of cell mediated immunity were investigated. Results : The natural killer cell activity was significantly correlated with Hb (Spearman r=0.616, p=0.001), MCV (Spearman r=0.678, p=0.000) and MCH (Spearman r=.0721, p=0.000). But there was no significant correlations with iron, ferritin, TIBC and Iron/TIBC ratio. In Mann-Whitney test and Chi=Square test, NK cell activity was significantly associated with MCV, MCH and hemoglobin. Conclusions : There was significantly decreased natural killer cell activity in iron-deficient patients. In this study, hemoglobin, MCV and MCH are parameters of the NK cell activity in cell-mediated immunity. As a result, iron deficiency itself is a determinant of the NK cell acitivity.
