정신장애 노인 환자들에서 간이기억검사의 문항 분석

박종한(Jong Han Park),이종훈(Jong Hun Lee),문병상(Byung Sang Mun) 대한노인정신의학회 2004 노인정신의학 Vol.8 No.2

문항반응이론을 이용하여 간이기억검사의 문항을 분석하여 문항 난이도와 문항 변별도를 평가했다. 노인 정신질환자 중 기억 장애가 있는 332명과 없는 354명에서 2-모수로지스틱모델을 이용하여 문항의 난이도와 변별도를 계산했다. 문항들의 난이도는 평균(±표준편차)이 -0.878(±1.176)이고 범위는 -3.299~0.902이었다. 변별도는 0.346 내지 1.848이었고, 평균(±SD)은 -1.051(±0.392)이었다. 19개 문항의 변별도가 적정 수준 이상이었고, 논리적 기억의 지연성회상의 변별도가 최고이었다. 결론적으로 모든 문항들은 기억력 선별 검사로서 p<0.01 수준에서 적절하다고 여겨진다. Objective:Analyses of the 24 items of the Mini-Memory Test (MiMeT) using the item response theory. Methods:Item difficulty and item discrimination of all items were evaluated with the 2-parametric logistic model in elderly psychiatric patients with memory impairment (n=332, 48.4%) and without (n=354, 51.6%). The BILOG 3 for Windows was employed for the analysis. Results:The mean item difficulty (±SD) was -0.878 (±1.176), with range of -3.299~0.902. The mean item discrimination (±SD) was -1.051(±0.392), ranging from 0.346 to 1.848. Discriminations of 19 items were above appropriate level and the delayed recall of short story items of the long-term memory had the highest discrimination. Conclusion:All the MiMeT items were thought as having no problems as memory screening test in terms of difficulty and discrimination at the level of p<0.01.

지역사회 노인들에서 치매의 주관적 판단과 객관적 평가 간의 차이

박종한(Jong Han Park),홍미령(Mi Ryung Hong),장병원(Byung Won Jang),변용찬(Yong Chan Byun) 대한노인정신의학회 2005 노인정신의학 Vol.9 No.2

Objective : Evaluation of how much the presence of dementia is underdiagnosed or misdiagnosed in the elderly population by themselves. Method : The number of self-professed dementia cases was compared to the estimated number of cases with cognitive impairment based on the Korean version of the Mini-Mental State Examination (MMSEK) employed in a nationwide survey “Need assessment of the long-term care in the elderly” in three representative areas of Korea. The would-be dementia cases were analyzed. Results : Only eighteen (0.7%) of 2,638 reported the presence of dementia while 414 (15.7%) were diagnosed as having questionable cognitive impairment and 385 (14.6%) as having definite cognitive impairment on the MMSEK. On the other hand, some of the self-professed “dementia” cases were not impaired on the MMSEK. Conclusion : The public should be educated on clinical manifestations of dementia for its early diagnosis and appropriate treatment because they are mostly without understanding about dementia.

능성어 (Epinephelus septemfasciatus) 자치어의 골격발달

본 연구는 능성어 자치어의 골격발달을 관찰하여 분류학적 연구의 기초자료로 이용하고자 실시하였다. 자치어는 전남 여수시 거문도에 위치한 해상가두리에서 사육하던 어미로부터 채란하여 사육한 것을 대상으로 관찰하였다. 자치어의 사육 수온범위는 21.5~24.5°C (평균 23.0±1.5°C)였다. 부화 직후의 난황을 가진 자어는 골화가 전혀 이루어지지 않았고, 평균전장 2.66 mm에 달하면 윗턱을 구성하는 전상악골과 주상악 골이 골화되었고, 아래턱을 구성하는 치골이 골화하였으며, 두개골의 기저를 형성하는 부설골이 골화하였다. 새개부를 형성하는 전새개골과 주새개골의 골화가 시작되었다. 꼬리지느러미를 지지하는 미골은 추골과 골편으로 이루어진 미골복합체로 구성된다. 평균 전장 2.59 mm까지는 전혀 골화가 일어나지 않았고, 미부봉상골이 45°로 휘어져 있다. 담기골의 골화는 평균 전장 6.12 mm에 첫 번째 혈관간극이 뒷지느러미 2개의 가시와 관절되어 가장 먼저 골화가 시작되고, 신경간극 또한 등 지느러미 2개의 가시와 관절되어 골화하기 시작하였으며, 혈관간극과 신경간극은 평균 전장 21.9 mm에 골화가 완료되는개체가 출현하였다. This research has been launched in order to observe the osteological development of sevenband grouper, Epinephelus septemfasciatus larvae and juveniles and will be used for the basic data of phylogenetically systematics research. We got some samples of larvae and juveniles from a adult fish which belongs to the sea cage in Geomun-do, Yeosu-si, Jeolla-namdo province, and we have watched them. The average of breeding water temperature was 21.5~24.5°C (average 23.0±1.5 °C). In yolk-sac larvae just after hatching, ossification was not observed at all, and when the average total length reached 2.66 mm, the premaxillary and maxillary forming the upper jaw, dentary forming the lower jaw, and parasphenoid forming the skull base were ossified. In addition, the preopercle and opercle forming the opercular region began to be ossified. The caudal skeleton supporting the caudal fin is built with the caudal complex consisting of the malleus and incus. Until the average total length reached 2.59 mm, ossification did not occur at all and the urostyle bent at 45-degree angle. As to the ossification of the pterygiophore, when the average total length was 6.12 mm, the first interhemal spine began to be ossified in articulation with two spines of the anal fin, and the synapse also began to be ossified in articulation with two spines of the dorsal fin. When the average total length was 21.9 mm, individuals with completed ossification of the interhemal spines and synaptic clefts began to appear.

The major findings on prevalence of dementia, nature of questionable dementia, early cognitive symptoms of Alzheimer's disease, the meaning of a screening test for cognitive impairment, reliability of dementia diagnosis, variables affecting cognitive functions, relation of cognitive dysfunction to survival, and natural course of cognitive functions were summarized in this review.

코비드-19(COVID-19) 시대 인문학 교과의 효율적인 교수 방안 모색 ― 문화 관련 강의 사례를 중심으로

朴鍾漢 ( Park Jong Han ) 중국어문학회 2020 中國語文學誌 Vol.0 No.73

This study examines the ways in which one can find a new teaching method applicable to the new teaching environment that has arisen with the onslaught of COVID-19. For this purpose, this study makes use of the autobiographical case study method which is one of the qualitative research methods and tries to overcome its limitations through a small-scale questionnaire and Focus group interviews. In the ‘With Corona’ situation where one has to coexist with Corona-19, in-person and non-in-person classes can always be interchangeable. This paper argues that in order to achieve a desired result in the face of the current harsh conditions, one has to create “routines” that can be consistently applied in any situation and expand them. This study suggests three routines: the instructor’s lecture preparation routines, learner’s performance routines, and the routines that the instructor can refer to when he or she is giving lectures. Although this study has some limitations in terms of research methods, it will be meaningful and valuable in that it provides routines that both instructors and learners can utilize in a ‘With Corona’ situation that is likely to go on after the fall semester of 2020.

박성한(Sung-han Park),박종두(Jong-du Park),김정인(Jeong-in Kim) 한국비영리학회 2022 한국비영리연구 Vol.21 No.2

본 연구는 영구임대아파트에 거주하는 노인 무료급식서비스의 만족요인을 확인함으로써 무료급식서비스의 질 향상과 효과적인 서비스 제공에 기여하는 것에 목적이 있다. 이에 본 연구는 M종합사회복지관 무료급식 이용자 183명을 대상으로 델파이조사와 AHP 조사를 진행하고, AHP 결과의 일관성이 높은 54명의 설문 응답자를 중심으로 2021년 9월부터 2022년 2월까지 연구를 진행하였다. 델파이분석 결과 무료급식 만족도에 미치는 중요 요인으로 음식의 맛, 음식의 양, 반찬의 가짓수, 위생상태, 배송시간, 조리식품, 간편식, 육류, 어패류, 채소류, 직원의 친절성, 안부 건강확인 총 12가지가 확인되었다. 델파이분석을 중심으로 우선순위를 확인한 AHP분석결과 위생상태 > 음식의 맛 > 조리식품 > 어패류 > 채소류 > 안부건강확인 > 직원의 친절성 > 배송시간 > 육류 > 간편식 > 음식의 양 > 반찬의 가짓수 순으로 나타났다. 본 연구는 노인들의 무료급식 만족에 미치는 세부 요인을 확인한 결과로서, 효과적인 무료급식서비스 제공을 통한 대상자들의 건강과 만족에 기여할 수 있다. This study confirms the satisfaction of free meal service for the elderly living in permanent rental apartments. The purpose of the study is to contribute to improving the quality of free meal services and providing effective services. Therefore, this study targeted 183 users of free meals at M Social Welfare Center in N-gu. The study conducted Delphi surveys and AHP surveys. 54 questionnaire respondents with high consistency in AHP results were centered. The study was conducted from September 2021 to February 2022. As a result of Delphi analysis, the factors affecting the satisfaction of free meals are as follows. There are a total of 12 types of food, such as taste, amount of food, number of side dishes, hygiene, delivery time, cooked food, convenient food, meat, seafood, vegetables, kindness of employees, and safety confirmation. As a result of AHP analysis, which confirmed priorities based on Delphi analysis, hygiene > taste of food > cooked food > fish and shellfish > vegetables > safety confirmation > kindness of employees > delivery time > meat > amount of food > number of side dishes. This study will contribute to the effective provision of free meal services by identifying the factors affecting the satisfaction of free meals for the elderly.
