Objective: The aim of this study was to evaluate retention practices commonly employed by orthodontists. The objectives were to identify the types of retainer frequently used and to investigate the variations in retention practice. Methods: A total of 97 orthodontists were randomly selected, and a questionnaire consisting of 25 multiple-choice questions sent to them by mail. Upon receiving of the completed questionnaires, the data were statistically analyzed. Results: A total of 32 responses were received; among these, 59.4% of orthodontists' practiced is in a government setting and 40.6% were in private practice. A vacuum-formed retainer was the most commonly used removable retainer for both maxillary (46.9%) and mandibular (46.9%) arches, followed by a Hawley retainer (maxilla, 43.8%; mandible, 37.5%), and a fixed retainer (maxilla, 3.1%; mandible, 9.4%). Of the responding orthodontists, 78.1% prescribed full-time wear (more than 20 h per day) for a duration of 3-9 months for a maxillary arch, compared to 71.9% for the mandibular arch. Only 18.8% of the orthodontists prescribed part-time wear of the retainer for the maxillary arch, compared to 21.9% for the mandibular arch. The majority of orthodontists did not instruct their patients to stop wearing removable retainers (71.9%) or fixed retainers (66.8%) at any specific time and they preferred their patients to continue wearing retainers. Conclusions: Vacuum-formed retainers are the most commonly used retainers among orthodontists. The majority of orthodontists prescribed full-time wear for more than 20 h per day with a duration of 3-9 months and preferred indefinite use of the retainer.

Local wall thinning and integrity degradation caused by several mechanisms, such as flow accelerated corrosion (FAC), cavitation, flashing and/or liquid drop impingements, are a main concern in carbon steel piping systems of nuclear power plant in terms of safety and operability. Thinned pipe management program (TPMP) had been developed and optimized to reduce the possibility of unplanned shutdown and/or power reduction due to pipe failure caused by wall thinning in the secondary side piping system. This program also consists of several technical elements such as prediction of wear rate for each component, prioritization of components for inspection, thickness measurement, calculation of actual wear and wear rate for each component. Decision making is associated with replacement or continuous service for thinned pipe components. Establishment of long-term strategy based on diagnosis of plant condition regarding overall wall thinning is also essential part of the program. Prediction models of wall thinning caused by FAC had been established for 24 operating nuclear plants. Long term strategies to manage the thinned pipe component were prepared and applied to each unit, which was reflecting plant specific design, operation, and inspection history, so that the structural integrity of piping system can be maintained. An alternative integrity assessment criterion and a computer program for thinned piping items were developed for the first time in the world, which was directly applicable to the secondary piping system of nuclear power plant. The thinned pipe management program is applied to all domestic nuclear power plants as a standard procedure form so that it contributes to preventing an accident caused by FAC.

The purpose of this paper is to classify fashion and trend, and examine how his fashionable philosophy reflects design. What affects his fashion philosophy is Western culture and Paris Revolution. Taking this opportunity, he outgrew the concept of haute couture and established specific fashion philosophy. His fashion philosophy is classified under consideration for women, respect for free emotions, recognition of tradition, and an active intercourse with many people. The characteristics of design through his philosophy are as following: 1. He wanted to release women from clothing restrained the body and make comfortable clothing which everyone can wear. This implies the consideration for women. It is the characteristics of his design to the harmony of functionality, simplicity, decoration and popularity. 2. He respected the free emotions and induced people to wear each parts of clothing which is dismantled freely within the limits coincided with clothing teleology-'wear', It implies autonomy. He also unfolded experimental design: gives the regular space between the clothing and the body and then distorts the body or maximizes modeling. It implies the beauty of space. 3. He elicited the modern design through recognition of tradition. It implies contemporaneousness. 4, As he thought that all of the concepts is based on human, he derived inspiration firm an active intercourse with many people, He established a new style through an active intercourse with artists because if he works alone, he would rise above the popular trend, It comes to the gest artist serieE and implies popularity, The characteristics of design in his fashion philosophy is classified into experimental design and practical design. But the important factor of his fashion philosophy is popularity so he would like to make popular clothing. He designs clothing which fit the public. It results from his firm fashion philosophy that his clothing is practical and decorative and he establishes his works meeting needs of modern. It is the reason that his clothing has perpetuity.

The purpose of this study is to identify the ritual dress used by the 12 religious bodies of Dankun followers to help understand the teachings of these currently operating religious groups in Korea. The findings from the survey and related literatures are used to analyze the characteristics of these ritual dresses in terms of their items, construction, form, and color. The results of the study are as follows: first, most of the religious groups of Dankun followers have established the code for ritual dresses and they are named as 'chaebok'(제복, sacrificial robes), 'yebok'(예복, ceremonial dress), 'chungbok'(정복, formal attire), 'pubbok'(법복, Buddhist formal dress), or 'tobok'(도복, Taoist garments). The official headgear is usually named as 'chaemo'(제모), 'soogun'(수건), 'moja'(모자), or 'yoogun'(유건, 儒巾). Though, there are some groups which do not use any specific names for headgear. Second, the ritual dresses of most groups are composed of the 'hanbok'(한복,韓服) or usual Western-style dress, a traditional outer wear, 'po'(포,袍), and a headgear, as a basic attire. Third, the traditional 'hanbok' is worn as a base garment and an outer wear is worn above. The different types of outer wear are used: mostly 'chaksu jueui jikyoun po'(착수주의직령포, 窄袖周衣直領袍) for men and 'kwangsu jikyoung po'(광수직령포, 廣袖直領袍) and other various styles for women. The headgear from the ancient times are worn by both men and women. Fourth, the most frequently-used color for ritual dress is white for both men and women's dress. The colors from the Yin and Yang ideology are also used in the ritual dresses. Finally, the kinds of materials are not considered as an important element for the ritual dresses.

In the oral cavity, the teeth undergo wear and corrosion throughout their lives. Progressive and constant tooth wear is a natural phenomenon of aging, but wear and corrosion due to specific factors are pathological factors. It can cause pathological damage of the occlusal surface, aesthetic problems, dimensional loss and jaw joint disorders. This case is a 26-year-old female patient with general tooth abrasion and erosion on the entire dentition. Diagnostic wax-up was fabricated based on the information including digital facial analysis, physiological stabilization, and evaluation of anterior crown length. Through the digital analysis, the necessary guides for crown lengthening were prepared and the mastication function and esthetics were evaluated by using temporary crowns. Definitive prosthesis was fabricated with the zirconia restorations. The results were satisfactory when they were observed 3 months of follow-up.
