Objective: To investigate skeletal and dental changes after application of a mandibular setback surgery-first orthodontic treatment approach in cases of skeletal Class III malocclusion. Methods: A retrospective study of 34 patients (23 men, 11 women; mean age, 26.2 ± 6.6 years) with skeletal Class III deformities, who underwent surgery-first orthodontic treatment, was conducted. Skeletal landmarks in the maxilla and mandible at three time points, pre-treatment (T0), immediate-postoperative (T1), and post-treatment (T2), were analyzed using cone-beam computed tomography (CBCT)-generated half-cephalograms. Results: The significant T0 to T1 mandibular changes occurred ?9.24 ± 3.97 mm horizontally. From T1 to T2, the mandible tended to move forward 1.22 ± 2.02 mm, while the condylar position (Cd to Po-perpendicular plane) shifted backward, and the coronoid process (Cp to FH plane) moved vertically. Between T1 and T2, the vertical dimension changed significantly (p < 0.05). Changes in the vertical dimension were significantly correlated to T1 to T2 changes in the Cd to Po-perpendicular plane (r = ?0.671, p = 0.034), and in the Cp to FH plane (r = 0.733, p = 0.016), as well as to T0 to T1 changes in the Cp to Poperpendicular plane (r = 0.758, p = 0.011). Conclusions: Greater alterations in the vertical dimension caused larger post-treatment (T2) stage skeletal changes. Studying the mandibular position in relation to the post-surgical vertical dimension emphasized the integral importance of vertical dimension control and proximal segment management to the success of surgery-first orthodontic treatment.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

The major protocol features of the rodent uterotrophic assay have been evaluated using a range of reference chemicals. The protocol variables considered include the selection of the test species and route of chemical administration, the age of the test animals, the maintenance diet used, and the specificity of the assay for estrogens. The rodents were ovariectomized under general anesthesia via bilateral flank incisions and randomly assigned to groups of 5 animals. This study investigated the estrogenic effects of phthalates, which are DEHP and DBP, suspected as endocrine disruptors. It is concluded that three daily subcutaneous administration of test chemicals, which are di-ethylhexyl phthalate(DEHP) and di-n-butyl phthalate(DBP), to 9 week-old rodents. The results revealed that DEHP & DBP show similar uterotrophic activity in the rat and the mouse, using subcutaneous administration. DEHP and DBP failed to affect any of these parameters, which are body weight, mammary gland, vaginal and uterus histopathology. but, DBP increased uterus weight to only one rat of 1.0 g/kg group. The results conform the need for rigorous attention to experimental design and criteria for assessing estrogenic activity.

긍정심리자본이 종업원 인게이지먼트와 이직의도에 미치는 영향

이윤성(Lee, Youn-Sung),장영철(Chang, Young-Chul),정병헌(Chung, Byung-Heon),김진욱(Kim, Jin-Wook)0 글로벌경영학회 2014 글로벌경영학회지 Vol.11 No.2

오늘날 기업들은 다양한 변화 속에서 지속적인 성장을 위해서 부단한 노력을 기울이고 있다. 특히 인적 자원의 효과적인 관리가 조직의 성장의 중심에 있기 때문에 조직구성원 자신이 속해있는 조직과 자신의 직무에 몰입을 할 수 있는 환경을 만들어 가는 것에 대한 연구를 진행하였다. 이로 인하여 조직구성원들의 이직을 방지하여 인적자원 개발에 투자되는 시간과 비용을 절감할 수 있는 방법에 대한 방안이 도출 될 수 있을 것이다. 본 논문에서는 긍정심리자본의 하위요인 가운데 종업원 인게이지먼트(조직몰입과 직무몰입)에 영향을 주어 이직의도를 낮추는 요인이 무엇인가를 검증하였다. 긍정심리자본은 경제적 자본, 인적 자본, 그리고 사회적 자본을 넘어선 하나의 자본 개념이다. 최근 긍정심리자본과 직무성과 관련 연구가 많이 이루어지고 있는데, 긍정심리자본은 직무성과의 선행요인으로 직무성과에 긍정적 영향을 주는 것으로 보고되고 있다. 본 연구의 결과, 긍정심리자본의 4가지 요인 중 희망과 복원력이 조직몰입 및 직무몰입에 정(+)의 영향을 주는 것으로 나타났다. 또한 이직의도를 낮추는 긍정심리자본의 요인으로도 희망과 복원력이 중요한 영향을 미치는 것으로 연구되었다. 이는 목표를 향해 에너지를 집중하는 긍정적인 동기적 상태인 희망과 위험한 상황 또는 역경에 직면했을 때 긍정적으로 상황에 대처하고 적응하는 특성인 복원력이 종업원의 직무 및 조직 몰입을 높이고 이직의도을 낮추는 데 의미있는 요인으로 작용하는 것을 알 수 있다. Companies these days make ceaseless efforts to continue their sustainable growth in the midst of diverse and turbulent changes. It is not too much to say that at the core of organizational growth lies efficient management of human resources. It is very much important to create an environment where each and every member of the organization can be fully engaged in his/her job and organization, which is a key to preventing turnover of members and, in turn, saving time and cost for development of human resources. This paper validates which factor of the positive psychological capital influences employees’ engagement (organizational engagement and job commitment) so as to lower down the intention to quit. This paper shows that hope and resilience among the four factors of the positive psychological capital positively influence organizational engagement as well as job commitment. Hope and resilience are also found out to play an important role in reducing the intention to quit. This can be translated into that hope, a state of being positively motivated to focus one’s energy toward the goal and resilience, capacity to sustain and bounce back when beset by adversity and risky situations, play a meaningful role to enhance organizational and job commitment of employees as well as to reduce the intention to quit.

Oraganic and inorganic substances are oxidated by OH radicals produced by illumination of near-UV with wavelength of 365mm on the TiO₂ photocatalyst. With photocatalytic oxidation, we can degrade organic pollutants, thus apply this new method to water treatment processes. In this study, operation factors for water treatment process were suggested by comparing phenol degradation efficiency under various experimental conditions of cation metal additive(FeCl3), and oxidation additive (H₂O₂), then initial phenol concentration on the photocatalytic oxidation results were examined. With the operating conditions achieved by these experiments, the possibility and validity of applying photocatalytic oxidation to the actual water treatment process were considered. As a result, conditions of reactant Recirculation Flow Rate 275 mL/min, Aeration Rate 2 LPM and UV+TiO₂+H₂O₂(500 mg/L) proved to be appropriate for water treatment process using photocatalytic oxidation. The degradation efficiency of phenol decreased with increasing influent concentrations. The UV+TiO₂+H₂O₂ photocatalytic oxidation conducted in this study is considered to be possibly applied to the advanced oxidation process of drinking water treatment processes, and the post-treatment process of biological wastewater treatment processes.
