형식적 표현은 프로토콜의 명세와 분석을 위하여, 컴퓨터 네트워크나 데이타 통신에 관심있는 여러 사람들에 의해 수년간 연구되어 왔다. 본 논문에서는 형식적 표현 방법중 언어 지향적 모델을 택하여, 6가지 모델링 기법 -- Temporal Logic, LOTOS. Estelle, CSP. Prolog, Concurrent Pascal -- 을 살펴보고, 표현 방법이나 명세서의 차이점, 그들이 가지는 특징들을 비교, 고찰해 보고자 한다.

Distributional patterns of benthic microalgae were studied in the tidal flats of Saemangeum lake, Korea, from March 2007 to October 2009. As benthic microalgae of tidal flats of Saemangeum lake, 44 species belong to 5 classes were identified. Diatoms predominated the benthic microalgal flora with 75.0% of total species occurred. Dominant species were Achnanthes lanceolata, Aulacoseira granulata, Cymbella tumida, Fragilaria construens var. ventor, Melosira varians, Navicula cryptocephala, Navicula cryptocephala var. veneta, Nitzschia palea, and Paralia sulcata. The cell density and biomass of benthic microalgae were highest in 2009, and clear tendency of increment was observed at D1 and D2 sites. In vertical profiles, cell density and biomass of the benthic microalgae showed maximum cells and biomass at 0~1 mm depth of sediments from all sampled sites.

The purpose of this study was to analyze and identify the differences in mood status and psychological happiness according to the exercise participation of the airline’s cabin crew(exercise experience, exercise participation frequency in 1 week, exercise participation time per day). In order to achieve the objective of this study, POMS: profiles of Mood states and psychological happiness questionnaire were used targeting 276 domestic K airline cabin crew. Results of using t-test and One - way ANOVA analysis in order to analyze the differences of mood status and psychological happiness and to analyze the differences of mood status and psychological happiness according to the degree of exercise participation are as follows. First, in the result of analyzing the differences in mood state according to the individual characteristics, male crew showed higher average score of vitality then the female crew and showed significant difference in anxiety, depression, anger, fatigue, and confusion. Second, as the result of analyzing the difference between the psychological happiness according to individual characteristics, female crew showed significant difference in happiness and a sense of immersion factor than the male crew. Third, as the result of analyzing the difference of group mood status according to exercise participation, statistically, significant influenced showed in all mood (anxiety, depression, anger, vigor, fatigue and confusion) status depending on the exercise experience. Fourth, according to the result of analyzing differences in collective psychological happiness according to exercise participation, in the exercise participation experience, exercise participation frequency and exercise participation time, groups of less than 6 month, 6 months - 3 year and more than 3 years were confirmed to have significant difference from exercise non-participant group.

Carbon dioxide (CO2) laser is one of the most widely used lasers in dermatology. CO2 laser can precisely ablate the skin with good hemostasis, which makes it an ideal surgical laser. With the development of pulsed CO2 laser, which enabled cleaner ablation with less residual thermal damage, CO2 laser resurfacing became the gold standard for skin rejuvenation. The rejuvenation effect of full-face CO2 laser resurfacing is unparalleled to other methods; however, it is associated with a relative high incidence of side effects and prolonged downtime. Fractional CO2 laser was developed to overcome this problem. With a new technology of fractionating the laser beam into hundreds of microbeams, fractional CO2 laser resurfacing can improve various skin conditions including skin laxity, photodamage, and acne scars with short downtime and significantly lesser side effects. For optimal treatment results, clinicians have to decide the treatment depth and density based on proper understanding of the laser tissue interaction and underlying skin conditions.

We report a case of mos 45, X/46,XY mixed gonadal dysgenesis. An 22-year old female patient was admitted to our department for evaluation of primary amenorrhea. The chromosome karyotype of the patient was mos 45, X/46, XY. On the laparotomy there was an infantile uterus, fallopian tubes, and streak gonads. Bilateral gonadectomies were taken. Gonads showed tubular patterns and ovarian-like stroma histologically in left and right respectively so as to be diagnosed as mixed gonadal dysgenesis. The follow-up treatment has been combined estrogen-progesterone replacement therapy so far.

Papuloerythroderma of Ofuji (PEO) is an uncommon entity of unknown etiology, characterized by coalescing erythematous papules sparing skin folds. A number of cases have described the association of this disorder with malignant with pathology, mainly with cutaneous T cell lymphoma. Such reports give rise to the suggestion that PEO may be a precursor of lymphoma or a form of cutaneous T cell lymphoma. We report a case of PEO, which was diagnosed as cutaneous T-cell lymphoma only 2 months after the development of skin lesions, and rapidly progressed. This case suggests the presence of a variant of cutaneous T cell lymphoma with clinical feature of PEO, which is different from mycosis fungoides or Sezary syndrome.
