객체지향 패러다임에서 응집도가 높은 클래스들은 단 하나의 데이터 요소만이 정의되고 모든 메소드(또는 연산)들이 그 데이터 요소 상에서 수행되거나, 메소드와 데이터 요소간에 최대연결이 이루어진 클래스이다. 따라서 데이터 요소의 증가와 최대연결을 저해하는 연산들은 클래스의 응집을 저해하는 주 요인들이다. 본 연구에서는 이러한 저해요인들에 근거하여, 응집도에 관한 우리의 직관과 더욱 일치하는 측정을 할 수 있는 새로운 클래스 응집도 척도인 CM(Cohesion Metric)을 제안하였다. 본 연구에서는 응집도를 저해하는 요인의 식별을 위해 참조 그래프(reference graph)를 이용하고, 참조 그래프의 분석을 기초로 하여 클래스의 응집도를 측정하였다. 또한 제한된 CM 측정값이 응집도 척도가 만족해하는 특성들을 만족함을 보였고, 기존 응집도 척도들과의 비교평가를 통해서 CM이 기존의 척도들보다 향상된 측정을 제시함을 보였다.

객체지향 패러다임에서 저해용인에 기반한 응집도 척도

In object-oriented paradigm, highly cohesive classes define only a data factor(instance variable) whose all methods(or operations) refer to, or have the maximum connection among elements in a class. Therefore, an increase in the number of the data factors, and the operations to obstruct the maximum connection among elements in a class are the main factors to decrease the class cohesion. In this paper, we propose a new measure, called CM(Cohesion Measure), which can measure the class cohesion more consistently with our intuition on the basis of factors to decrease it. We use the reference graph in order to find the decreasing factors of the class cohesion, and measure the class cohesion on the basis of analysis of the domain reference graph. We also show that the proposed CM metrics satisfy the properties that the cohesion measures should satisfy, and that it can provide more upgraded measures than the existing measures through comparing it with the measures of existing cohesion.

Atypical Spitz`s nevus is a rare spitzoid melanocytic proliferations with an uncertain malignant potential. Atypical Spitz`s nevus have overlapping features of both Spitz nevi and spitzoid melanoma, and consequently, generate controversies with diagnosis and management. Herein, we report a case of atypical Spitz`s nevus developing on the lower right leg of a 46-year-old man. Histologically, the lesion shows numerous uniform nests of spindle cells and epithelioid cells in the dermis. The lesion had a high Ki-index, prominent cellular density, but not enough to consider a diagnosis of melanoma. The nevus was removed by total excisions. No recurrences or metastases were detected during the follow-up period of 6 months.

Platelet rich plasma is derived from fresh whole blood that contains a high concentration of platelets. There are many clinical reports of the effect of PRP on diverse surgical procedures, especially in the fields of orthopedic surgery and periodontic surgery. Recently, PRP has been rapidly developing as a method of wound healing and skin rejuvenation. Therefore, the aim of this study was to evaluate the effectiveness of PRP on wound healing after herpes zoster infection. We analyzed the medical records and clinical photographs of 12 patients who underwent 1∼2 PRP treatments of superficial ulcers after herpes zoster infection. The wounds that were treated by PRP healed rapidly compare to non-treated wounds. This study shows that PRP treatment is a safe and effective treatment option for skin ulcer after herpes zoster infection. (Korean J Dermatol 2011;49(10):918∼922)

Cancer that tends to metastasize to other internal organs also involves the skin with various clinical features. We report two cases of metastatic skin cancer that showed multiple erythematous patches on the trunk. Two patients presented with erythematous macules and a patch with telangiectasia on the trunk and chest wall. A microscopic examination of the skin biopsy specimens showed infiltration of large atypical cells with hyperchromatic nuclei and scant cytoplasm in the dermis. Using variable immunohistochemical staining, we identified the primary origin of the cancer, which was breast cancer. Usually, cutaneous metastatic carcinoma shows solitary and multiple nodules on the trunk, but there are also many unusual clinical findings. Dermatologists should pay attention to the sudden onset of symptomless erythematous patches and nodules on the trunk and conduct a skin biopsy and immunohistochemical staining.

Clinical manifestations of mycosis fungoides can vary from the classical type, which is associated with patch, plaque and tumor, to the rare atypical type which is associated with erythroderma, hypopigmentation or hyperpigmentation, and an ichthyosiform patch. A 45-year-old man presented with a 10-year history of asymptomatic erythroderma and an ichthyosiform patch on his trunk and lower extremities. On physical examination, there were asymptomatic erythematous nodules on the Rt. thigh and a palpable lymph node on the Lt. popliteal area. A histopathologic study showed infiltration of atypical cells into the upper dermis with mononuclear cell infiltration of the epidermis. On immunohistochemistry, atypical cells showed positivity for CD3, CD4, and CD8 staining, and negativity for CD20 staining. TCR-gamma rearrangement showed monoclonality. Excisional biopsy of Lt. popliteal lymph nodes showed pathology findings compatible with that of the trunk. A diagnosis of stage IVa mycosis fungoides, which is associated with erythroderma and ichthyosiform manifestations, was made. The patient was treated by a combination of PUVA and MTX chemotherapy and is still on regular follow up. (Korean J Dermatol 2011; 49(2):169~174)

본 연구의 목적은 중등학교 현장의 필요에 부응하는 영어교사교육과 교육정책 수립의 필요성을 강조하기 위한 것이다. 연구 목적을 위하여 146명의 중등교사(중학교 교사 53명과 고등학교 교사 93명)를 대상으로 설문조사를 실시하였으며, 설문조사 결과는 교사들 자신, 학생 및 학교, 그리고 교사교육 프로그램과 영어로만 하는 영어수업 정책으로 나누어 그에 대한 중등교사들의 의견에 대해서 분석하였다. 중등영어교육의 개선을 위해서 무엇이 필요한지에 대한 보다 상세한 정보를 얻기 위하여 본 연구에서는 또한 설문 조사에 참여한 교사들 중 20명의 교사들로 하여금 학교 현장의 문제점에 대해 자유롭게 글로 기술하게 하였으며, 그 결과는 교사 자신, 학생 및 학교, 제도 및 정책에 기인하는 문 제들로 분류하여 기술하였다. 연구 결과를 바탕으로 내린 결론은 우리나라 중등학교 영어교육의 실 질적인 개선을 위해서는 현재의 영어교사교육제도 및 교육정책이 학교 현장의 필요에 부응하도록 바 뀌는 것이 우선되어야 한다는 것이다. 이를 위한 몇 가지 제언을 기술하였다. This study is to call for a change in the English teacher education and policy to meet the needs in the secondary schools. In order to investigate the problems in the secondary school English education, the study used two means of data collection: a questionnaire survey and a written description of the problems, The participants were 146 secondary school (53 middle school and 93 high school) English teachers, The survey results were analyzed for the teachers` opinions about themselves, their students/school, the pre-service/in-service teacher education programs and the English-only policy. The written descriptions were analyzed for the teachers`` perceived problems in their schools as well as the current educational system/policy, which were described in three categories: teacher problems, student/school problems and system/policy problems. Based on the results, the study concludes that many of the problems that exist in our secondary school English education result from the teacher education and policy that are not sensitive enough to the needs in the schools and in order to bring about any real improvement in it a change in the current English teacher education and policy must be preceded.

병력 청취와 신체 검사가 중요함을 시사한 쯔쯔가무

Tsutsugamushi disease is an acute febrile illness that is caused by infection with Orientia tsutsugamushi. The diagnosis is based on the patient`s history of exposure, the characteristic clinical features and serologic testing. But the diagnosis can be difficult when an eschar is overlooked or it is absent. Making the differential diagnosis with drug eruption is especially difficult when a skin rash develops with a prior medication history for fever or myalgia. We report here on 3 cases of Tsutsugamushi disease. Two of the cases were misdiagnosed as drug eruption due to medication for carbuncle or back pain. For the other case, Tsutsugamushi disease was accompanied with allergic contact dermatitis due to Rhus (lacquer tree). All the patients had fever, myalgia and an atypical skin rash that differed from that of drug eruption and allergic contact dermatitis. The detection of eschar was possible by having a clinical suspicion of Tsutsugamushi disease. Thus, we report here on three cases of Tsutsugamushi disease and these cases show the importance of taking a complete medical history and performing a thorough physical examination.
