The purpose of this paper is exploring changes in land use pattern when considering environmental carrying capacity. A sustainable development requires a society to define sustainability constraints, environmental carrying capacity. Environmental carrying capacity can be defined as a level of human activity a region can sustain at a desired level of quality of environment. This concept of environmental carrying capacity can be applied to land use to explore sustainable land use pattern. Since land use pattern can affect environment in an important way, exploring sustainable land use pattern within the limit of environmental carrying capacity can suggest useful implications for a sustainable regional management and planning. For this purpose, this paper built the environmental carrying capacity land use model and applied it to the Metropolitan Area, Korea. System dynamics modeling methods was used to build the model. The model developed in this paper consisted of 6sectors; population, housing, industry, land, environment, and traffic sector. The model limits its main focus on the NO2 level as an indicator of quality of environment in Metropolitan Area. Box model was translated into system dynamics model and combined to urban dynamics model to estimate NO2 level, the maximum number of population, industry structure, housing and maximum amount of land use for industrial, housing, and green space that can sustain desirable NO2 level. Metropolitan area was divided into 16 areas and the model was applied to each area. Since NO2 is flowing in and out from each area, model was built to allow this transboundering nature of air pollutants. Based on the model estimation, several policy implications for a sustainable land use pattern was discussed.

The main objective of this research was to understand the characteristics of printed geometric patterns through the statistical & qualitative analysis of fashion appeared in contemporary female collections 2011 S/S to 2013 A/W. Data collection of 294 was done through review of 'pr$\hat{e}$t-$\grave{a}$-porter Collections' of three major fashion cities; Paris, Milan and NY. Statistical analysis of frequency was conducted. Also qualitative interpretation of natural print design' characteristics were completed. The main findings were as followed; 1,636 of the total 15,852 designs were printed patterns in 12 Collections and the occurrence rate of printed geometric patterns in three collections were 8.6% in Milan, 9.2% in Paris and 12.9% in N.Y. Most geometric patterns were the types of compact or medium density in a front patterns with a variety of sizes and mainly applied to the one piece dress or two piece clothing item combination styles. Formative Characteristics of printed geometric patterns were classified into four types. First, a variety of thicknesses and shapes, such as a line or a rectangle shape to take advantage of the types of the typical geometric pattern. Second types were using the motifs which inspired by geometric shapes such as point, circle star and other special geometric shapes and arranging them regularly with various sizes and density. The third was repeated particular motifs which based on complex and sophisticated mathematical formulas. Fourth were the specific diagram types of bold and free shapes or dividing the flat and arranging them without rules, or the combination type of various geometric motifs.

The Tibetan people are an ethnic group that is native to Tibet who have adapted to the region's harsh climate and environment, and developed their own culture. Religion played a central role in maintaining its traditional culture and society in the history. The objective of this study is to understand Tibetan costume and religion, and examine patterns that appear on the costume to study their religious symbolism. The significance of this study lies in explaining the symbolisms of the patterns that appear on the costume in terms of cultural maintenance and change. Based on literature review, I summarized the data about Tibet's environment, history and religion, and divided the residential district into three: ${\ddot{U}}$-Tsang, Amdo, Khamba. Then, I organized each region's characteristics and clothes, and studied Tibetan Buddhism (Vajrayana) costumes and features of the patterns that appear on the costumes. Through combining these data, I would like to examine the religious symbolism of the costume pattern of Tibet. Buddhism is at the heart of cultural and social maintenance and change in Tibet, and the patterns shown in the costume is influenced mostly from Buddhism. The features of general Tibetan costume vary with the region and life style, but the patterns that appear on the costume are used over a wide area to represent good luck and the spread of Buddhist teachings. The costumes for religious rites vary with religious sects, but most of the patterns are commonly used. The symbolism of pattern is a form of figure that represents the human psyche and physical world. The symbolism of pattern implies meanings such as compensation or futuristic wish. First, the lucky omen normally means long life, happiness and peace, and means religious salvation in Buddhist perspective. Second, warding off evil spirits normally means avoiding misfortune, and means dignity and self-protection, and protection of Buddhadharma in Buddhist perspective.

Currently, subway crowding is estimated by observing a specific point at specific hours once or twice every 1 or 2 years. Given the extensive subway network in Seoul Metropolitan Area covering 588 stations, 11 lines and 80 transfer stations as of 2017, implementing crowding mitigation policy may have its limitations due to data uncertainty. A proposal has recently been made to effectively use smart card data, which generates big data on the overall subway traffic related to an estimated 8 million passengers per day. To mitigate subway crowding, this study proposes two viable options based on data related to smart card used in Seoul Metropolitan Area. One is to create a subway passenger pattern model to accurately estimate subway crowding, while the other is to prove effectiveness of early bird policy to distribute subway demand that is concentrated at certain stations and certain time. A subway passenger pattern model was created to estimate the passenger routes based on subway terminal ID at the entrance and exit and data by hours. To that end, we propose assigning passengers at the routes similar to the shortest routes based on an assumption that passengers choose the fastest routes. In the model, passenger flow is simulated every minute, and subway crowding level by station and line at every hour is analyzed while station usage pattern is identified by depending on passenger paths. For early bird policy, highly crowded stations will be categorized based on congestion level extracted from subway passenger pattern model and viability of a policy which transfers certain traveling demands to early commuting hours in those stations will be reviewed. In particular, review will be conducted on the impact of policy implemented at certain stations on other stations and lines from subway network as a whole. Lastly, we proposed that smart card based subway passenger pattern model established through this study used in decision making process to ensure effective implementation of public transport policy.

The aim of this study was to suggest the future direction of diagnostic and evaluative pattern identification questionnaire (PIQ) by reviewing the state of development and utilization of PIQ according to Korean classification of disease-U (KCD-U). We surveyed the database of OASIS, NDSL, KISS, DBPIA, and Pub-med to know the kinds of developed and developing PIQ of Korean medicine. We used 'Pattern Identification' and 'Questionnaire' to find suitable papers. The inclusion criteria met 47 cases. The number of PIQ before 2000yrs, between 2001 to 2005, 2006-2010, 2011-2015 were 2, 5, 18, 22cases. The number of PIQ belonged to the disease of Korean medicine, the pathological symptom of korean medicine, the Sasang constitutional pattern identification and etc according to KCD-U were 20(42.6%), 8(17%), 9(19.1%) and 10(21.3%). Twenties among forty seven PIQ were validated, and the rest of them were not validated. The distribution of the numbers of PIQ were significantly different according to KCD-U (p=0.003). The direction of Utilization of PIQ was 36 questionnaires in diagnosing PI, 14 cases in evaluating health state, 4cases in evaluating effects of a treatment and 8 ones in diagnosing Sasang constitutional types. This study reveals the status on validated and non-validated PIQ of Korean medicine and suggests the basic information for the direction of developing PIQ in the future.

소셜 미디어 애플리케이션 및 모바일 장치의 광범위한 사용으로 인해 데이터 트래픽이 지속해서 증가하고 있다. 소셜 미디어 애플리케이션은 끝없이 많은 양의 멀티미디어 트래픽, 특히 비디오 트래픽을 생성하고 있다. YouTube, Daily Motion 및 Netflix와 같은 많은 소셜 미디어 플랫폼이 생성하는 것이다. 이러한 플랫폼에서는 다른 비디오와 비교하여 몇 개의 인기 비디오가 여러 번 요청된다. 이러한 인기 있는 비디오는 지속적인 사용자 요구 사항을 충족하기 위해 사용자 주변에 캐시해야 한다. MEC는 일관된 사용자 요구와 사용자 근접 캐시를 위한 필수 패러다임으로 부상했다. 시간에 따라 사용자 요구 패턴이 어떻게 달라지는지를 이해하는 것이 과제이다. 본 논문은 공개 데이터셋인 MovieLens 20M, MovieLens 100K, The Movies Dataset 3개를 분석하여 시간에 따른 사용자 요청 패턴을 찾는다. 모든 데이터셋의 시간별, 일별, 월별 및 연간 추세를 확인할 수 있다. MEC 기반 비디오 캐시 시나리오에서 사용자 요청 패턴을 분석 및 생성함으로써, 많은 연구에서 사용될 수 있을 것이다.
