A significant body of research have been published to support the predictive validity of psychopathy measures. But most PCL studies have not focused on the raters scoring these psychopathy measures. This study coded how often and what information was provided regarding raters who scored the psychopathy measures in 61 published PCL studies. Our findings are noteworthy for demonstrating that PCL studies have been less likely provide information about the raters using psychopathy measures to readers. Specifically, most of PCL studies did not provide any information about who scored the PCL, the rater’s level of training or experiences regarding risk assessment. Future study implication includes exploring the effect of rater’s training, experiences, and characteristics on variability on psychopathy measures enhance risk assessment practice in clinical and forensic settings. 지난 몇 십 년 동안 사이코패시를 측정하는 재범 위험성 평가도구의 신뢰도와 타당도를 지지하는 많은 연구들이 발표되면서 사이코패시 측정도구는 형사정책 현장에서 위험성 평가도구 중 가장 널리 사용되고 있다. 사이코패시 점수의 예측 타당도가 평가자의 특성 및 훈련 정도에 따라 달라질 수 있다는 최근의 연구 결과에도 불구하고, 사이코패시 측정도구를 사용한 평가자들에 대한 논의나 연구는 부족한 실정이다. 본 연구에서는 사이코패시 측정도구를 사용한 61개의 기존 연구들을 바탕으로 각 연구에서 사이코패시 측정도구를 사용한 평가자들에 대한 정보를 확인하였다. 그 결과, 대부분의 연구들은 사이코패시 측정도구를 누가 사용하였는지, 평가자는 사이코패시 전문가 지침서에서 제시한 요건을 충족할 만한 학위 및 훈련을 받았는지, 법임상 현장 경험이 있었는지 등에 대한 정보를 제공하지 않았다. 본 연구는 위험성 평가 시 사이코패시 측정의 예측타당도 및 신뢰도를 높이기 위해 사이코패시 측정도구를 사용하는 평가자들에 대한 적절한 교육 및 지속적인 훈련의 필요성을 제안한다.

Purpose: To evaluate the change of visual quality after wearing orthokeratology lenses overnight.Methods: This study included 13 patients (24 eyes) who wore orthokeratology lenses for the first time. Visual quality was assessed with the optical quality analysis system (OQAS) using the double-pass technique. The value of modulation transfer function (MTF) cutoff, Strehl ratio, and objective scatter index (OSI) were measured at baseline and 4 weeks after wearing the lenses. Results: The mean spherical equivalent decreased from -2.70 ± 1.03 diopters (D) to 0.03 ± 0.36 D after 4 weeks of wearing orthokeratology lenses and uncorrected visual acuity improved from log MAR 0.88 ± 0.17 to log MAR 0.03 ± 0.04. The MTF cutoff decreased from 38.20 ± 11.01 to 34.79 ± 10.30 and the Strehl ratio decreased from 0.24 ± 0.07 to 0.21 ± 0.07 but without statistical significance. The OSI significantly increased from 0.38 ± 0.19 to 0.72 ± 0.40 after wearing orthokeratology lenses. Conclusions: Orthokeratology lenses were effective for correction of myopia and astigmatism. The OSI increased after wearing the lenses, but MFT cutoff and Strehl ratios were not affected.J Korean Ophthalmol Soc 2014;55(11):1595-1599

Purpose: To determine influences of intraoperative foveal traction during membrane peeling in idiopathic epiretinal membrane (ERM) surgery. Methods: This retrospective observational study included 46 eyes of 46 patients with idiopathic ERM who underwent pars plana vitrectomy with ERM and internal limiting membrane peeling from February 2015 to September 2015. The presence of intraoperative foveal traction during membrane peeling was reviewed using video records. The main outcome measures were best-corrected visual acuity (BCVA), central foveal thickness (CFT), foveal contour, and photoreceptor inner segment/outer segment junction disruption using optical coherence tomography at baseline and at 1, 3, 6, and 12 months after surgery. Results: Group 1 (ERM with intraoperative foveal traction) included 22 eyes, and group 2 (ERM without intraoperative foveal traction) included 24 eyes. Preoperatively, convex pattern ERM was observed more often in group 1. Group 1 had a significantly thicker CFT and a lower BCVA compared to group 2 at baseline and during the first 6 months, but the final postoperative BCVA and CFT were not significantly different between the groups at 12 months. Among 22 eyes, 12 eyes (54.5%) were restored to flat or concave ERM patterns at an average of 5.4 months after surgery in group 1, and 18 out of 24 eyes (75%) recovered at 2.4 months (p < 0.01) in group 2. Conclusions: Preoperative thick CFT and convex pattern ERM indicated a high possibility of intraoperative foveal traction in idiopathic ERM surgery. There were no differences in long-term BCVA and restoration of foveal configuration according to foveal traction during membrane peeling. 목적: 특발 망막앞막 환자에서 막제거술을 시행하는 과정에서 발생한 중심와 견인이 수술 결과에 미치는 영향에 대해 분석해 보고자 하였다. 대상과 방법: 2015년 2월부터 9월까지 본원에서 특발 망막앞막으로 진단받고 유리체절제술 및 막제거술을 시행받은 환자 46명 46안을 대상으로 후향적으로 분석하였다. 수술영상을 판독하여 막제거술 과정에서 중심와에 견인이 발생하였는지를 확인하였고, 술 전, 술 후 1개월, 3개월, 6개월, 12개월에 최대교정시력 및 빛간섭단층촬영상에서 중심망막두께, 중심오목형태, 시세포 내절/외절 상태의 변화를 조사하였다. 결과: 술 중 중심와 견인이 발생한 22안은 견인이 발생하지 않은 24안에 비해 술 전 볼록형 형태가 많았고 중심망막두께가 두꺼웠으며 술 전 시력이 낮았다. 술 후 6개월까지 견인이 발생했던 군에서 시력이 낮고 중심망막두께가 두꺼웠으나 12개월에는 두 군의 차이가 없었다. 술 후 황반의 형태가 편평형 또는 오목형으로 회복되는 기간은 견인이 발생한 군에서 5.4개월, 견인이 발생하지 않은 군에서 2.4개월이었다(p<0.01). 결론: 특발 망막앞막 환자에서 수술 전 중심망막두께가 두껍고 볼록형 형태일수록 막제거술 과정 중 중심와 견인이 발생할 가능성이 높으며, 막제거술 과정 중 중심와 견인의 발생 유무에 따른 장기적 시력 및 해부학적 결과는 차이가 없었다.

산업공학의 서비스 과학에의 기여를 위한 서비스 정의

As the service industry continues to grow in importance, a new research field called service science has formed so as to conduct more comprehensive and scientific analysis of service. However, much further research is required until we can develop the common terminology and methodology for service design and improvement. A foundational step toward this is giving a lucid definition to service which reflects the intrinsic qualities of it. Many of the service definitions mentioned in existing studies had the limitation that they considered service as the residual from physical products, or tried to conceptualize service based on some characteristics. In this paper we compare and analyze existing studies, discuss about the essential nature of services, and suggest a more comprehensive investigation into service.

전혜민,홍순원,임범진,장항석 대한병리학회 2012 Journal of Pathology and Translational Medicine Vol.46 No.6

Background: To define the exact boundary of the intrathyroid and extrathyroid aspects of a gland when determining the extent of cancer invasion, we plan to clarify the definition of sizable vascular structures, which is one of the helpful histologic clues in determining a minimal extrathyroid extension. We hypothesized that arterial wall thicknesses in extrathyroid soft tissue would be significantly different from the arteries in the thyroid parenchyma. Methods: Twenty cases of papillary carcinoma were selected. The numbers and wall thicknesses of the arteries and arterioles in intrathyroid and extrathyroid tissue were evaluated. The absence of nerve tissue in the thyroid gland was confirmed using the S-100 protein immunohistochemical stain. Results: The comparison of the mean thicknesses of the total arteries between the extrathyroid and intrathyroid tissues in the retrospective study (26.88 μm vs. 15.07 μm, respectively) and the prospective study (35.24 μm vs. 16.52 μm, respectively) revealed significant differences (p=0.000). The greatest thickness of the intrathyroid arteries was 67.93 μm. Conclusions: According to our results, the study showed that the extrathyroidal arteries were significantly thicker than the intrathyroidal arteries. We suggest that the sizable blood vessels of extrathyroidal arteries should be greater than 67.93 μm in thickness.

Purpose: To evaluate the efficacy of Optical Quality Analysis System (OQAS<SUP>Ⓡ) instrument for the assessment of dry eye syndrome. Methods: Dynamic recording of double-pass (DP) retinal images was performed in 1 eye dry eye patients (20 eyes) and in healthy controls (20 eyes) for 20 seconds after eye blinking. Results: The mean objective scatter Index (OSI) value was 4.53 in dry eyes, 0.67 in healthy eyes and the standard deviation of OSI was 1.20 in dry eyes and 1.18 in healthy eyes. The patients with dry eyes showed significantly higher mean OSI and standard deviation values. Ocular scatter increased over time and significant changes occurred 13.5 seconds after blinking. The difference in OSI value between 0 second and 20 seconds was significantly greater in dry eye patients (4.15) than in controls (0.32). Conclusions: Ocular scatter increased over time after blinking. The dry eye patients had larger and more variable ocular scatter index than the controls. OQAS<SUP>Ⓡ may be useful to detect and follow-up tear film-related patient complaints in dry eye syndrome. J Korean Ophthalmol Soc 2014;55(11):1600-1605

Purpose: To evaluate the efficacy and stability of AcrySof Toric intraocular lens (IOL) implants and to analyze the miscorrection that resulted after implantation. Methods: This retrospective study included 422 eyes of 348 patients who underwent cataract surgery with implantation of the AcrySof toric IOL between December 2011 and June 2013. We evaluated uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), keratometry and refraction preoperatively and 3 months postoperatively. The axis of implanted AcrySof Toric IOL was measured using the KR-1W aberrometer before mydriasis. At 3 months postoperatively, patients with a residual cylindrical power of 0.50 diopters (D) or more, and having an IOL rotation of 10 degrees (°) or more were considered having miscorrection. Results: UCVA (log MAR) improved from 0.58 ± 0.35 to 0.18 ± 0.26. Preoperative corneal astigmatism was 1.46 ± 0.72 D and postoperative refractive cylindrical power was 0.45 ± 0.30 D. The postoperative miscorrection was 50.5% in the T3 group, 35.7% in the T4 group, and 27.2% in the T5 group. The incidence of overcorrection was significantly higher in the T3 group than in the T4 and T5 group. In eyes with with-the-rule (WTR) astigmatism, overcorrection was found in 36.4% (32/88 eyes), while in eyes with against-the-rule (ATR) astigmatism, undercorrection was found in 37.6% of cases (44/117 eyes). There were five cases of IOL rotation at 3 months postoperatively. Conclusions: AcrySof Toric IOL was effective in correcting corneal astigmatism and had good rotational stability. However, the incidence of miscorrection, especially for overcorrection, was higher with lower power toric IOL. Patients with WTR astigmatism tend to have overcorrection, while those with ATR show a tendency toward undercorrection, suggesting that these changes considered at the time of cataract surgery.J Korean Ophthalmol Soc 2014;55(11):1636-1641

어순 교체에 따른 한국어 피동문 실시간 처리 연구 - 일본인 학습자를 대상으로 -

전혜민,고기영 국제한국언어문화학회 2022 한국언어문화학 Vol.19 No.3

본 연구는 일본인 한국어 학습자의 한국어 피동문에 나타나는 어순 교체에 대한 습득을 살펴보는 데 목적이 있다. 한국어 피동문 어순 실현은 구조적 기준(어순 전형성)과 의미역 기준(논항 배분 전형성)에 따라 유표성이 다르게 나타나며, 어떠한 기준을 우선적 단서로 삼아 문장을 처리하는지에 따라 습득의 어려움을 예상할 수 있다. 본 연구에서는 한국어 모어화자 30명과 일본인 학습자 60명을 대상으로 하여 피동문 실시간(online) 처리를 관찰하기 위해 자기 조절 읽기 과제(self-paced reading)를 실시하였다. 그 결과, 한국어 모어화자는 의미적 단서보다 구조적 단서에 민감성을 보여 ‘피동작주-동작주’ 순서로 나타난 문장을 ‘동작주-피동작주’보다 빠르게 처리하였다. 그러나 이와 달리 일본인 학습자는 숙달도와 상관없이 두 유형의 문장의 읽기 속도에 차이가 나타나지 않아 구조적 단서와 의미적 단서에 모두 민감성을 보이지 않았다. 이러한 연구 결과는 일본인 한국어 학습자가 L1과 L2의 형태적 유사성에도 불구하고 피동문 실시간 문장 처리에 있어 여전히 어려움을 겪는다는 것을 의미한다. This study investigated whether L1 Japanese learners of Korean can acquire the word order alternations of the Korean passive. In self-paced reading, Korean native speakers (n = 30) showed greater sensitivity to structural cues than semantic ones, while Japanese L2 Korean speakers (n = 60) showed no difference in reading time, regardless of proficiency, as well as showing no sensitivity to structural or semantic cues. These results indicate that Japanese L2 Korean speakers have difficulty with the on-line processing of sentences despite the morphological congruency between L1 and L2.
