Even ordinary-looking plays can have a profound meaning. Based on this assumption, Eugene Pink (1960) has established an analytical model of play with five elements, namely "delight", "meaning", "community", "rules" and "tools." It was an effort to reflect on the true meaning of play beyond the cortical entertaining nature of play. In this study, it was carried out that all the texts containing images and performance from the EBS character "Pengsu" were selected, since he emerged as a new star in 2019. And also his play structure was analyzed by applying the Pink's model. As a result, Pengsu's play structure was confirmed to be systematic and complete as a play prototype because it was well-organized with five elements of play. It was regarded as a successful character that skillfully attracts participants to the play world. Among the components of the play, "fun" was found to be his funny appearance, sudden and unconventional behavior, "meaning" was the elimination of authoritarianism, self-esteeming and energizing, "community" was a multi-platform media user who crossed off-on-line, analog-digital-line, "rules" was to set his concept fixed as a young stranger with an ego to unreveal his identity, and "tools" was shown as his character itself and continual discourse. It shows that until now, Pengsu has a social net function of quite spreading the positive meaning of encouragement and comfort, advice and guide, consideration and forgiveness, introspection and nirvana to all members of our society, including the youth who are struggling with uncertainty and anxiety by showing rather exaggerated and stimulating performance that precisely combines these play elements.

The Seoul Metropolitan Area's economy has undergone structural changes since the 1990s. With recent structural changes in the Korean economy in mind, this paper employs a decomposition analysis of Gross Regional Domestic Product per head and labor productivity to examine how the region's economic performance has changed relative to that of Korea since the 1900s. There are some findings. First, a strong cumulative causation process, derived from industrial linkages and agglomeration effects, has oocurred in the Seoul Metropolitan Area, widening economic disparities between the Seoul Metropolitan Area and the other regions especially since the Korean financial crisis in 1997 mainly due to Gyeonggi province's overwhelming cumulative GRDP growth relative to the national average. Second, the Seoul Metropolitan Area has begun w display good economic performance in terms of labour productivity relative w the national average since the late 1990s, with the region's industrial upgrading being implemented. Finally, manufacturing, financial intermediation and communications have made sensitive contributions to relative Seoul Metropolitan Area's labor productivity growth.

It is not a rare occasion that certain dental procedures involving tooth reduction being peformed under inadequate water cooling due to a variety of reasons. This situation could possibly inflict the critical insult to the pulpal tissue of indicated tooth. The purpose of this experiment was to study the pattern of diffusion of external heat produced during routine dental procedures into the pulpal tissue. 30 stone blocks containing three lower second primary molars were used for certain restorative procedures and the temperature of the indicated tooth surface was measured by thermography(Inframetrics 600) and further used as a baseline data for the finite element analysis model fabrication designed in order to evaluate the pattern of thermal diffusion. The ranges of highest surface temperature measured from several dental procedures under water cooling and non-water cooling were $30.8^{\circ}C{\sim}43.6^{\circ}C$ and $51.2^{\circ}C{\sim}103.4^{\circ}C$ respectively. Among procedures studied, crown preparation showed the highest value and amalgam removal showed the lowest. Comparisons between data measured under water cooling and non-water cooling conditions have shown the statistically significant difference(p<0.05). All the non-cooling conditions have shown the relatively larger increment of temperature change at the pulp horn area than the cooling conditions. The results of this study strongly indicate that the water coolant is the essential element in restorative procedures for the maintenance of healthy pulp. Further related studies involving more procedures and conditions are recommended.

The quality control of pathological specimens is important for accurate molecular pathology testing. This study evaluated that specimen factors affecting the DNA quality during tissue processing and sample types for BRAF, EGFR, and KRAS mutations tests. One thousand seven hundred and seventy-two molecular pathology tests were investigated for the factors influencing the DNA quality, such as sample type, formalin fixation time, and reexamination status. Cytology samples stored in a saline solution had better DNA quality than commercial cytology preservation. Tissue samples fixed in formalin within 24 hours had better DNA quality than the samples fixed over 24 hours. Between the types of samples, fresh tissue samples and tissue samples with a high tumor cell density had relatively better DNA quality than the formalin-fixed paraffin-embedded (FFPE) tissues and cytology specimens. Of real-time PCR, the non-PNA Ct value increased proportionally with samples held for longer than 24 hours in formalin, and that the formalin-fixed time affects the sample DNA quality. In conclusion, the appropriate tumor cellularity and 10% neutral formalin fixation time are the most important factors for maintaining the DNA quality. These factors should be managed properly for an accurate pathological molecular test to ensure optimal DNA quality.

두 선박이 정면에서 마주치며 선박간 상호 통항하거나 상대선을 추월할 경우 각 선박의 선체형상과 선속에 의한 유체력 상호작용에 따른 선박간 간섭력이 발생한다. 선박간 간섭력의 주요한 평가 요소인 횡력과 회두 모멘트의 측정을 통해 두 선박이 근접하였을 때의 위험도와 충돌을 예측할 수 있다. 선행된 간섭력에 관한 연구는 대부분 경험에 의하거나 이론적인 측면에서 관련 연구가 진행되어왔으며, 학계에서 통상적으로 널리 알려진 뉴턴의 연구(1960)에서는 깊은 수심에서 두 선박을 평행하게 항주시켰을 때 선박간 최대 흡인력은 두 선박이 정횡으로 나란하게 위치되는 지점에서 발생하고, 이때의 간섭력은 선속의 제곱에 비례한다고 추정하였다. 현대의 조선기술이 발전함에 따라 선박의 크기는 점점 대형화되고 선박의 운항 효율성 증진을 위한 다양한 선형이 개발되어 실선에 적용되고 있다. 이런 경향에 따라 과거에 비해 현대 선박 운항환경에서의 선박간 간섭은 선박의 크기 및 선형에 의한 영향이 클 것으로 판단된다. 본 연구에서는 선박의 종류별로 대표 선종을 선정하여 두 선박이 정면에서 마주치며 통과하는 운항조건에서의 선속 증가에 따른 선박 상호간 간섭력의 변화를 통상적으로 사용되는 선박조종시뮬레이터를 이용하여 실험 및 분석하여 상관관계를 도출하였다. 선박 유형에 따른 시뮬레이션 실험 결과 최대 횡력은 주로 선미 부근에서 발생하였고 최대 회두모멘트는 선수가 근접할 때 발생하였으며, 선속이 증가할수록 선박 상호간 근접거리가 좁혀졌고 선형별로 각기 다른 선속에서 선미 충돌이 발생하였다. 이 실험연구는 선형에 따른 선박 상호간 근접 시의 횡거리와 통과속력에 대한 기준 설정의 연구 근간을 마련하였고 선박간 교항시 안전운항을 위한 지침이 될 것으로 판단된다.

Objectives: Salivary gland neoplasms are a diverse group of benign and malignant tumors with a wide range of biologic behaviors. The surgeon must understand the pathologic behavior of each tumor type to develop an appropriate treatment plan. The authors planned this study to evaluate our clinical experiences and establish a new treatment strategy. Materials and Methods: From Sep. 1997 to June 2001, 25 cases of major salivary gland tumors which were underwent surgery were evaluated retrospectively. Results: 20 cases were benign and 5 were malignant. Most(17) of benign cases were pleomorphic adenoma and they showed wide distribution in age. Also we experienced other benign such as warthin's tumor, oncocytoma. In malignant, there were 2 cases of carcinoma ex-pleomorphic adenoma, 2 cases of adenoid cystic carcinoma, and one lymphoma. In carcinoma ex-pleomorphic adenoma, one showed dismal prognosis in spite of multimodality and the other were recurrent to be salvaged. Conclusion: We concluded that salivary gland neoplasms are challenging because of their relative infrequency, inconsistent classification, and highly variable biologic behavior. We need to establish new effective strategies with the regard of factors influencing survival.

In this paper, we propose a study on the purchasing intent of the new e-commerce consumer, the coronavirus may once again drive the structural change of China's economy, and the new online marketing model will be noticed during the epidemic. Through 438 questionnaires collected on the Internet, frequency analysis, element analysis, reliability analysis and structural equation analysis were performed using SPSS V22.0 and AMOS V22.0 methods. Study the validation of hypotheses in the model to reveal the reasons why consumers in the new e-business are exposed. The results show that e-commerce features of Internet celebrities and individual characteristics of Internet celebrities can only enhance consumers' satisfaction. Quasi social relationships only increase consumer satisfaction without generating the will to purchase directly. Consumer satisfaction is the core foundation that dominates long-term consumption. E-commerce should focus on the ability of online celebrities to sell their expertise and the adaptability of value and product characteristics when conducting online celebrity marketing.

High-level radioactive waste (HLW) such as spent fuel is inevitably produced when nuclear power plants are operated. A geological repository has been considered as one of the most adequate options for the disposal of HLW, and it will be constructed in host rock at a depth of 500~1,000 meters below ground level with the concept of an engineered barrier system (EBS) and a natural barrier system. The compacted bentonite buffer is one of the most important components of the EBS. As the compacted bentonite buffer is located between disposal canisters with spent fuel and the host rock, it can restrain the release of radionuclides and protect canisters from the inflow of groundwater. Because of inflow of groundwater into the compacted bentonite buffer, it is essential to investigate soil-water characteristic curves (SWCC) of the compacted bentonite buffer in order to evaluate the entire safety performance of the EBS. Therefore, this paper conducted laboratory experiments to analyze the SWCC for a Korean Ca-type compacted bentonite buffer considering dry density, confined or unconfined condition, and drying or wetting path. There was no significant difference of SWCC considering dry density under unconfined condition. Furthermore, it was found that there was higher water suction in unconfined condition that in confined condition, and higher water suction during drying path than during wetting path.

Filmic spaces are not only a core expressive factors that can embody both internal and external meanings of films, but also play an important role for initiating dramatic context in terms of narratives. They establish visible environment in which provocative incidents occur and characters' behaviors are induced, include characters' psychology or emotional meanings of narratives and provoke tensions through symbolic meanings and the implicit function of surface background. This paper, therefore, analyzes the film, , by focusing on the dramatic function of narrative space. This film provides insights and thoughts through deep philosophical reflection, by escaping from the convention of such a genre, through deep philosophical reflection, by escaping from the convention of such a genre, though it belongs seemingly to the crime thriller genre using Mexico's drug cartel as it main material. In the film, narrative spaces are responsible for emotions invoking dramatic tensions beyond provocative incidents and the elaborately planned and controlled mise-en-scene absorbed audiences' attention by organizing ultimate suspense. In conclusion, flow and dramatic lingering imagery of this film might be achieved by power of scenes rather than plot factors. This study thus explained the correlation between narrative spaces and dramatic immersion, by analyzing spaces appearing in and visualized construction. It is hoped that this will further extends the pattern of researches on dramatic immersion, which have been primarily focused on plots and characters.
