For the purpose of evaluating the effect of both direct retainer design and bony absorption degree around abutment of indirect retainer on the supporting tissue of abutment of indirect retainer, dislodging force was transmitted to unilateral distal extension RPD bases. Analysis of stress distributed within the supporting tissue around abutment of indirect retainer was carried out. Using three-dimensional photoelastic stress analysis method and the conclusion is a follows. 1. According to the extent of force which the direct retainer of the most distal abutment tooth, the amount of force transmitted to the abutment tooth of indirect retainer was small. 2. Of all the cases, Mandibular first premolar which was used abutment tooth of indirect retainer, buccal, mesial and distal sides represented compression stress and lingual side represented tensile stress. 3. The more bone resorption of abutment tooth of indirect retainer, the more distortion of buccal and distal side of abutment tooth was existed and the extent of compression stress which was existed and distal side to abutment tooth was large. 4. When the alveolar bone around the abutment with indircet retainer is normal. The amount of force transmitted on abutment with indirect retainer was small in the order of Akers clasp, RPA clasp, RPI clasp. 5. When the alveolar bone around the abutment with indirect retainer has been absorbed 20% and 30%, the amount of force transmitted on abutment with indirect retainer was small in the order of RPA calsp, RPI clasp, Akers clasp. 6. When denture is displaced, shape of the direct retainer reciprocating abutment affect much the function of indirect retainer.

Han, Ji-Young,Park, Seo Hee,Kim, Joohyung,Hwang, Kyung-Gyun,Park, Chang-Joo Korean Academy of Periodontology 2021 Journal of Periodontal & Implant Science Vol.51 No.3

Purpose: The aim of this study was to evaluate clinical factors affecting the longevity of fixed retainers and the influence of fixed retainers on periodontal health in periodontitis patients. Methods: In total, 52 patients with at least 2 years of follow-up after periodontal and orthodontic treatment were included in this study. After scaling and root planing, orthodontic treatment with fixed appliances or clear aligners was performed. Fixed retainers with twist-flex stainless steel wires were bonded to the palatal or lingual sides of anterior teeth. Changes in clinical parameters, including the plaque index, gingival index, calculus index (CI), probing pocket depth, and radiographic bone levels, were evaluated before bonding of fixed retainers and at a 12-month follow-up. Cumulative survival rates (CSRs) for retainer failure were evaluated according to sex, site, CI, stage of periodontitis, and the severity of the irregularity with the log-rank test and hazard ratios (HRs). Results: Twelve months after bonding of fixed retainers, improvements were observed in all clinical parameters except CI and radiographic bone gain. The overall CSR of the retainers with a CI <1 at the 12-month follow-up after bonding of fixed retainers was significantly higher than that of the retainers with a CI ≥1 at the 12-month follow-up (log-rank test; P<0.001). Patients with stage III (grade B or C) periodontitis had a higher multivariate HR for retainer failure (5.4; 95% confidence interval, 1.22-23.91; P=0.026) than patients with stage I (grade A or B) periodontitis. Conclusions: Although fixed retainers were bonded in periodontitis patients, periodontal health was well maintained if supportive periodontal treatment with repeated oral hygiene education was provided. Nonetheless, fixed retainer failure occurred more frequently in patients who had stage III (grade B or C) periodontitis or a CI ≥1 at 12-month follow-up after bonding of fixed retainers.

임진왜란기(壬辰倭亂期) 분조(分朝) 구성원의 행적에 관한 고찰

조인희,최윤오 역사실학회 2020 역사와실학 Vol.73 No.-

The purpose of this paper is to examine the specific activities of the members of Bunjo cabinet. For the research, examination on the selection of the meritorious retainer escorting Prince Gwanghae was made based on the Annals of Chosun dynasty and personal records. The following are the clues to the criteria for selecting the meritorious retainer escorting Prince Gwanghae and other meritorious retainers. 1 In the case of Hoseong meritorious retainer, he was recognized as a servant of King Seonjo or Gwanghaegun when he was ordered to leave due to official duties. This exception applies for Weesung meritorious retainers as well. Unlike Hoseong meritorious retainers, Weesung meritorious retainers could be selected as a meritorious subject even if it participated in only one of the first and second divisions. 3 Even if he participated in both the first and second divisions, he may not win the first prize. The figures who participated in the cabinet were treated as honored guests or received a considerable number of government posts related to the Prince Gwanghae's education. However not all of them were engaged in Bunjo cabinet or cited. Those who joined the group after the launch of Bunjo cabinet were not selected as the first meritorious retainers. In addition, even if they served Prince Gwanghae without resignation, they may not be selected as the No.1 contributor. 6 Even if it was due to official duties, they could not be selected as meritorious retainers if they were outside for too long time. It is not clear whether this condition applies to Weesung meritorious retainers. 7 If a person who has been obedient was sinned and deformed at the time of discussion on the selection of meritorious retainers, he could be demoted. 본고의 목적은 분조 구성원의 구체적인 행적에 대해 고찰해 보는 것에 있다. 이를 위해 본고에서는 호성선무청난공신도감의궤(扈聖宣武淸難功臣都監儀軌)와 실록, 개인 문집을 중심으로 위성공신(衛聖功臣)의 선정 과정에 대해 살펴보고자 하였다. 이를 통해 알아낼 수 있었던 위성공신 및 호성, 선무, 청난공신의 선정 기준에 대한 단서는 다음과 같다. ① 호성공신의 경우, 공무로 인해 명을 받고 선조나 광해군의 곁을 떠날 경우에는 종시호종으로 인정받았다. 이 예외 사항은 위성공신에도 동일하게 보는 것이 타당하다. ② 호성공신과 달리 위성공신은 1, 2차 분조 중 어느 한 곳에만 참여한 경우에도 공신으로 선정될 수 있었다. ③ 1, 2차 분조에 모두 참여했다 하더라도 반드시 1등 공신으로 선정됐던 것은 아니다. ④ 분조에 참여한 인물들은 빈객의 대우를 받거나, 세자시강원 관련 벼슬을 받는 경우가 상당히 많았다. 그러나 빈객이나 세자시강원 관련 벼슬을 받았다고 반드시 분조에서 업무에 종사했거나 공신에 선정됐던 것은 아니다. ⑤ 공신 선정에서 설령 공무로 인한 것이었다 하더라도 장기간(3달) 이탈을 할 경우 호성공신에 선정되지 못할 수 있었다. ⑥ 종시호종한 자가 공신 선정 논의 시점에서 죄를 지어 부처(付處)되고 탈고신(奪告神)된 경우에는 강등될 수 있었다.

Norma Ab Rahman,Tze Fui Low,Nur Shaheera Idris 대한치과교정학회 2016 대한치과교정학회지 Vol.46 No.1

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.

수확 전 Aminoethoxyvinylglycine, 수확 전·후 1Methylcyclopropene 처리가 ‘미스홍’ 복숭아의 저온저장 중 과실 품질에 미치는 영향

유진기,박철호,권중근,이동훈,정희영,조영제,강인규 한국원예학회 2020 원예과학기술지 Vol.38 No.3

This study was carried out to investigate the effects of preharvest aminoethoxyvinylglycine (AVG, ReTainⓇ) and sprayable 1methylcyclopropene (1MCP, HarvistaTM) and postharvest 1MCP (SmartFreshTM) treatments on fruit quality in coldstored ‘Misshong’ peaches. Flesh firmness of control fruits was decreased to 2.9 Newton (N) after 3 days of storage. However, a week before harvest (WBH) ReTainⓇ and SmartFreshTM treatments maintained firmness at 7.9 N and 12.0 N for up to 6 days of storage, respectively. Titratable acidity of control fruits was decreased from 0.33% at harvest to 0.21% after 12 days of storage. However, ReTainⓇ and SmartFreshTM treatments maintained acidity at 0.26 and 0.30% until 12 days of storage, respectively. Ethylene production of control fruits was highly increased to 45.4 µL·kg1·h1 after 12 days of storage, while at 1 WBH ReTainⓇ (23.9 µL·kg1·h1) and SmartFreshTM (21.6 µL·kg1·h1) treatments resulted in lower ethylene production than control fruits. Soluble solids content of 1 WBH ReTainⓇ (10.5°Brix) was slightly lower than control fruits (11.0°Brix) at harvest, and fruit weight loss was not affected during the storage progress. Therefore, this study suggested that 1 WBH ReTainⓇ and SmartFreshTM treatments help maintain fruit quality in ‘Misshong’ peaches during cold storage. 본 연구는 수확 전 aminoethoxyvinylglycine(AVG, ReTainⓇ) 및 수체 살포용 1methylcyclopropene(1MCP, HarvistaTM)와 수확 후 훈증용 1MCP(SmartFreshTM) 처리가 ‘미스홍’ 복숭아 과실의 품질과 저장성에 미치는 영향을 구명하고자 실시되었다. 저장 중 과실의 경도 변화는 저장 3일 후부터 과실의 경도가 급격히 감소하여 무처리구의 경우 2.9N으로 감소하였으나, 수확 1주전 ReTainⓇ 처리구와 SmartFreshTM 처리구의 경우 저장 6일 후 경도가 각각 7.9N과 12.0N으로 상품성이 유지될 정도로 높게 유지되었다. 산 함량은 무처리구의 경우 수확 시 0.33%이던 산 함량이 저장 12일후 0.21%로 급격히 감소하였으나, 수확 전 ReTainⓇ과 HarvistaTM 처리구들의 경우 저장 12일 후 0.26 ‑ 0.30%로 무처리구와 비교하여 높게 유지되었다. 에틸렌 발생량은 저장 12일 후 무처리구의 경우 45.4µL·kg1·h1으로 급격히 증가하였으나, 수확 1주 전 ReTainⓇ 처리구와 SmartFreshTM 처리구의 경우 각각 23.9와 21.6µL·kg1·h1으로 낮은 에틸렌 발생량을 보였다. 가용성 고형물 함량은 수확 2주 전 ReTainⓇ 처리구의 경우 수확 시 10.5°Brix로 무처리구 11.0°Brix와 비교하여 다소 낮은 경향을 보였다. 그리고 저장 중 과실 감모율은 증가하였으나 처리 간의 뚜렷한 차이를 보이지 않았다. 결론적으로, 수확 1주 전 ReTainⓇ 처리와 수확 후 SmartFreshTM 처리가 ‘미스홍’ 복숭아 과실의 저장 중 품질 유지에 효과적이었다.

최진휴(Jin-Hugh Choi),문철현(Cheol-Hyun Moon) 대한치과교정학회 2010 대한치과교정학회지 Vol.40 No.5

발음장애, 구토감 및 착용 불편감과 같은 보정장치에 대해 환자가 느끼는 불편감을 평가해보기 위해 고정식 교정장치로 교정치료를 받고 교정장치가 제거된 66명(남자 23명, 여자 43명; 평균연령 23.42 ± 10.19)의 교정환자를 대상으로 무작위로 두 군으로 배정한 후 고정식 교정장치를 제거한 다음 날 CWR 장착군에게는 구개를 완전히 덮는 구개 완전 피개형 보정장치인 conventional wraparound retainer (CWR)를 장착시키고 CCR 장착군에게는 구개를 말 발굽 모양으로 부분 피개하는 보정장치인 circumferential comfortable retainer (CCR)를 4주 동안 장착시킨 후 발음장애, 구토감 및 착용 불편감의 정도에 대해 100-mm visual analog scale (VAS)로 표시할 수 있도록 제작된 설문지를 통해 얻은 점수에 대해 통계적으로 비교 분석하였다. 연구결과 발음장애와 착용 불편감의 비교에서 CCR 장착군이 CWR 장착군에 비해 통계적으로 유의하게 낮았다 (p < 0.05). 구토감의 비교에서는 CCR 장착군이 CWR 장착군에 비해 낮은 점수를 보였지만 통계적으로는 유의한 차이를 보이지 않았다 (p = 0.146). 이상의 연구 결과로 circumferential comfortable retainer (CCR)는 발음장애를 감소시키고, 착용 불편감을 완화시킴으로써 환자의 협조도를 증진시켜 줄 수 있는바 고정식 교정장치를 이용한 교정치료 후 치료결과 유지에 도움이 될 수 있음을 시사하였다. (대치교정지 2010;40(5):325-333) Objective: The aim of this study was to illustrate the circumferential comfortable retainer (CCR) as a removable maxillary retainer with good potential patient compliance and to evaluate the discomfort of the retainers including distorted speech, gagging sensation and appliance discomfort. Methods: Sixty-six orthodontic patients (male, 23; female, 43; mean age, 23.42 ± 10.19 years) who received orthodontic treatment with fixed orthodontic appliances were randomly assigned to two groups after debonding, a conventional wraparound retainer (CWR) group that fully covers the palate with an acrylic plate and a highly polished surface, and a circumferential comfortable retainer (CCR) group which has a horseshoe shaped base plate with three folds on the anterior region. A questionnaire that had a visual analog scale (VAS) which consists of a 100-mm horizontal line with 2 end-points labeled “no discomfort” on the left and “worst discomfort” on the right, with regard to distorted speech, gagging sensation and discomfort, was administered to patients after 4 weeks of retainer wear. The Mann-Whitney test was used to test the hypothesis that there was no difference between the two retainers. Results: Comparing distorted speech and discomfort, the CCR group significantly had lower values than the CWR group (p < 0.05). Comparing gagging sensation, the CCR group had lower values than the CWR group but there were no statistically significant differences between groups (p = 0.146). Conclusions: In conclusion, the results suggest that the circumferential comfortable retainer (CCR) might facilitate patient compliance and thereby improve the maintenance of the fixed orthodontic treatment outcome.

Innovative customized CAD/CAM nickel-titanium lingual retainer versus standard stainless-steel lingual retainer: A randomized controlled trial

Emilie Gelin,Laurence Seidel,Annick Bruwier,Adelin Albert,Carole Charavet 대한치과교정학회 2020 대한치과교정학회지 Vol.50 No.6

Objective: To compare computer-aided design and computer-aided manufacturing (CAD/CAM) customized nitinol retainers with standard stainless-steel fixed retainers over a 12-month study period. Methods: This randomized controlled trial (RCT) was conducted on 62 patients randomly allocated to a control group that received stainless-steel retainers or a test group that received customized CAD/CAM nickel-titanium retainers. Four time points were defined: retainer placement (T0) and 1-month (T1), 6-month (T2), and 12-month (T3) follow-up appointments. At each time point, Little’s irregularity index (LII) (primary endpoint) and dental stability measurements such as intercanine width were recorded in addition to assessment of periodontal parameters. Radiological measurements such as the incisor mandibular plane angle (IMPA) were recorded at T0 and T3. Failure events (wire integrity or debonding) were assessed at each time point. Results: From T0 to T3, LII and other dental measurements showed no significant differences between the two groups. The data for periodontal parameters remained stable over the study period, except for the gingival index, which was slightly, but significantly, higher in the test group at T3 (p = 0.039). The IMPA angle showed no intergroup difference. The two groups showed no significant difference in debonding events. Conclusions: This RCT conducted over a 12-month period demonstrated no significant difference between customized CAD/CAM nickel-titanium lingual retainers and standard stainless-steel lingual retainers in terms of dental anterior stability and retainer survival. Both retainers eventually appeared to be equally effective in maintaining periodontal health.

Two-year survival analysis of twisted wire fixed retainer versus spiral wire and fiber-reinforced composite retainers

Farhad Sobouti,Vahid Rakhshan,Mahdi Gholamrezaei Saravi,Ali Zamanian,Mahsa Shariati 대한치과교정학회 2016 대한치과교정학회지 Vol.46 No.2

Objective: Traditional retainers (both metal and fiber-reinforced composite [FRC]) have limitations, and a retainer made from more flexible ligature wires might be advantageous. We aimed to compare an experimental design with two traditional retainers. Methods: In this prospective preliminary clinical trial, 150 post-treatment patients were enrolled and randomly divided into three groups of 50 patients each to receive mandibular canine-to-canine retainers made of FRC, flexible spiral wire (FSW), and twisted wire (TW). The patients were monitored monthly. The time at which the first signs of breakage/debonding were detected was recorded. The success rates of the retainers were compared using chi-squared, Kaplan-Meier, and Cox proportional-hazard regression analyses (α = 0.05). Results: In total, 42 patients in the FRC group, 41 in the FSW group, and 45 in the TW group completed the study. The 2-year failure rates were 35.7% in the FRC group, 26.8% in the FSW group, and 17.8% in the TW group. These rates differed insignificantly (chi-squared p = 0.167). According to the Kaplan-Meier analysis, failure occurred at 19.95 months in the FRC group, 21.37 months in the FSW group, and 22.36 months in the TW group. The differences between the survival rates in the three groups were not significant (Cox regression p = 0.146). Conclusions: Although the failure rate of the experimental retainer was two times lower than that of the FRC retainer, the difference was not statistically significant. The experimental TW retainer was successful, and larger studies are warranted to verify these results.

高麗 恭愍王 代 燕邸隨從功臣에 대한 一 考察 -柳淑의 動向 및 人的 關係網을 중심으로 -

柳炅來 한중인문학회 2010 한중인문학연구 Vol.30 No.-

본 논문에서는 江陵大君(후일의 공민왕)을 시종했던 燕邸隨從功臣들에 대해서, 대표적인 공신이었던 柳淑의 動向 및 공신들 간의 상호 人的 關係網에 중심을 두어 고찰하였다. 高麗忠肅王의 차남인 강릉대군은 어린 시절 入元宿衛하여 10여년간 원에 머물렀다. 당시 다양한 성향을 지닌 인물들이 그를 시종하였다. 1351년 귀국하여 즉위한 공민왕은 자신을 시종했던 인물들을 연저수종공신으로 책봉하여 포상했다. 이들 공신들은 상호 인아 관계를 통해 인적 관계망을 형성하였다. 하지만 서로 다른 다양한 면모를 지닌 공신들은 다양한 정치적 노선을 지향했고 여러 차례의 정변을 거치며 점 차 도태되는 양상을 보였다. 곧 1352년 趙日新의 난, 1356년 反元改革, 1363년 興王寺의 난, 1365년 辛旽 집권 등을 거치며 여러 공신들이 살해되거나 유배되었다. 수종공신 가운데 당대의 개혁․신진세력과도 연계된 獨步적인 존재였던 柳淑이 신돈에 의 해 실각한 이후 살해되었다. 이는 신돈이 집권하면서, 그나마 얼마 남지 않은 수종공신 세력이 결정적으로 정계에서 퇴장하였음을 상징적으로 드러낸다 할 것이다. In this paper, we examined the Yeonjeo(Beijing residence)-sujong meritorious retainers(燕邸隨從功臣) who served Gang-reung-dae-gun(江陵大君), with a main focus on the trend of representative meritorious retainer-Yu-Sook(柳淑 ; 1316∼1368) and mutual Human network(人的關係網). Gang-reung-dae-gun, the second son of the King Chung-Suk(忠肅王), entered the Yuan(元) Royal court as a kind of hostage. He resided in Yuan for ten years. At that time, people of various inclination attended and served him. In 1351, Gang-reung-dae-gun returned to Koryo and ascend the throne. He is the King Kong-Min(恭愍王). King Kong-Min rewarded people who served him as the Yeonjeo-sujong meritorious retainers. Some meritorious retainers(功臣) constituted Human network(人的 關係網) through mutual marital relations. But meritorious retainers of diverse features aimed at different political lines. And they were gradually weed out through many political convulsions. Throughout the rebellion of Cho il-sin(趙日新 ; ?∼ 1352) in 1352․the anti-Yuan reformation policies(反元 改革 政策) in 1356․the revolt of Heung-Wang temple(興王寺) led by Kim yong(金鏞 ; ?∼1363) in 1363․the centralization of Shin-don(辛旽 ; ?∼1371 ;priest), some of meritorious retainers were removed or exiled. Yu-Sook(柳淑), the unique retainer who was related to contemporary rising reformers, was overthrown and murdered by Shin-don. It symbolizes the political decline of Yeonjeo-sujong meritorious retainers. Decisively, As Shin-don took the helm of state affairs after the revolt of Heung-Wang temple was suppressd, Yeonjeo-sujong retainers meritorious left political circles.

조선전기 충훈부의 설립과 역할

고민정 진단학회 2019 진단학보 Vol.- No.133

This study considered the establishment, roles, and functions of Chunghunbu which was not specially taken note of by the precedent studies in terms of the institutional history. The study was done to clarify that Chunghunbu was established as ministry which is responsible for office work and respectful treatment of major contributors after several stages by starting from GaegugGonSinDogam with maintenance of the roles and functions in the process. GaegugGonSinDogam established in 1392 was responsible for working on record achievements of founding contributors, meritorious retainers of suppressing the first strife of princes, and meritorious retainers of suppressing the second strife of princes and the name was changed to the GonSinDogam in 1417. Office of Meritorious Subjects was again changed to Chunghunsa in 1434 and office work related to meritorious retainers performed by Liseongjegunbu was transferred to it in 1444. As Chunghunsa was raised to the status of Chunghunbu in 1454, it became Jeong 1 Pum ministry which takes charge of general office work and respectful treatment of meritorious retainers. Chunghunbu's roles and functions are various. But among them, three points were studied. First, Chunghunbu left behind records for recording the meritorious retainers and their descendants variously and operating it. Second, it made efforts to realize rights and interests of meritorious retainers including being responsible for office work on the state funerals for their respectful treatment. Third, it promoted friendship among kings and meritorious retainers and them by holding all kinds of banquets including parties in appreciation, Jungsakyeon, parties for departees, etc. for them. 본 연구는 선행연구에서 특별히 주목하지 않았던 충훈부의 설립 과정, 역할과 기능을 제도사적 측면에서 고찰하였다. 이는 충훈부가 개국공신도감에서부터 출발하여 여러 단계를 거친 후 공신에 관한 사무와 예우를 담당하는 아문으로 정립되었으며 그 과정에서 역할 및 기능에 관한 정비도 함께 이루어졌음을 해명하기 위한 것이다. 1392년 개국공신의 녹훈을 위해 설립된 개국공신도감은 점차 그 역할이 확대되어 삼공신의 녹훈과 삭훈에 관한 일을 담당하게 되었다. 1417년 공신도감, 1434년 충훈사로 개칭되었으며 1444년 관제 개편으로 이성제군부의 공신 관련 사무가 이관됨에 따라 공신에 관한 전반적인 일을 모두 아우르게 되었다. 1454년 마침내 충훈부로 승격되면서 공신에 관한 일상적인 사무와 예우를 관장하는 정1품 아문으로 존재하게 되었다. 충훈부의 역할과 기능은 매우 다양하지만 그 중에서 대략 세 가지를 고찰하였다. 첫째 충훈부는 공신과 그의 자손에 관한 다양한 기록과 충훈부의 운영을 위한 기록을 남겼다. 둘째 공신의 예우를 위해 예장에 관한 사무를 담당하는 등 공신의 권익을 실현시키기 위해 노력하였다. 셋째 공신을 위한 위로연, 중삭연, 전별연 등의 각종 연회를 주관하여 국왕과 공신, 공신간의 친목을 도모하였다.
