Objective : This study aimed to identify common activities with similar participation levels between community-dwelling individuals in the United States (US) and South Korea (Study 1), and analyze the changes in activity participation patterns across the adult lifespan in South Korea (Study 2). Methods : We administered the online survey-based Activity Card Sort version 3 (ACS-3) to adults living in the US and South Korea. In Study 1, we computed the average participation level and visualized 100 activities of the ACS-3 from both the US and Korean samples. The average participation level across the four age groups in Study 2 was calculated and visualized to understand the changes in patterns of involvement across the four ACS-3 domains in a Korean sample. Results : In Study 1, data from 161 Americans and 163 Koreans were analyzed. Of the 100 activities, 48 (instrumental: 20; leisure: 13; fitness/health: 6; social: 9) demonstrated similar levels of participation between the two samples. In Study 2, data from 420 Koreans were analyzed and a tendency for decreased participation with age was found in all domains, except for the instrumental domain. Conclusion : Common daily activities may be used as a means of intervention across cultures in occupational therapy. Protective approaches and support are recommended to optimize older adults’ participation in daily life. 목적 : 이 연구의 목적은 지역사회에 거주하는 미국인과 한국인이 참여하는 일상적 활동 중 공통된 활동을 도출하는 것과(연구 1) 생애주기 변동에 따라 한국인의 활동 참여 패턴의 변화를 분석하는 것이다(연구 2). 연구방법 : 온라인 조사를 통해 Activity Card Sort version 3 (ACS-3)를 미국인과 한국인에게 적용하였다. 연구 1에서는 100개 활동에 대한 참여수준의 평균을 분석하고 결과를 시각자료로 제시했다. 연구 2에서는 4개 연령집단의 참여수준의 평균이 ACS-3의 4개 도매인별로 어떻게 변화하는지를 분석하고 시각자료로 제시했다. 결과 : 연구 1에서는, 161건의 미국인 자료와 163건의 한국인 자료를 분석하였다. 100개 활동 중, 48개 활동(수단적 활동: 20개, 여가 활동: 13개, 건강 활동: 6개, 사회활동: 9개)에서 두 국가간 유사한 참여수준을 확인하였다. 연구 2에서는, 420건의 한국인 자료를 분석하였다. 나이가 들어감에 따라 모든 수단적 활동을 제외한 모든 도매인에서 참여수준이 저하되는 경향을 확인하였다. 결론 : 서로 다른 문화권에서도 공통적인 일상활동은 작업치료에서 문화의 제한을 받지 않는 치료적 수단으로 활용할 수 있다. 노인의 일상활동 참여를 최적화하기 위한 보호적 접근과 지지가 제안된다.

Park JI-Won,Park Jin-Mi,Eum Sangmi,Kim Jung Hee,Oh Jae Hoon,Choi Jinseon,Bach Tran The,Sinh Nguyen Van,Choi Sangho,Ahn Kyung-Seop,Lee Jae-Won 한국미생물·생명공학회 2022 한국미생물·생명공학회지 Vol.50 No.4

Ficus vasculosa Wall. ex Miq. (FV) has been used as a herbal medicine in Southeast Asia and its antioxidant activity has been shown in previous studies. However, it has not yet been elucidated whether FV exerts anti-inflammatory effects on activated-macrophages. Thus, we aimed to evaluate the ameliorative property of FV methanol extract (FM) on lipopolysaccharide (LPS)-induced inflammatory responses and the underlying molecular mechanisms in RAW264.7 macrophages. The experimental results indicated that FM decreased the production of inflammatory mediators (NO/PGE2) and the mRNA/protein expression of iNOS and COX-2 in LPS-stimulated RAW264.7 cells. FM also reduced the secretion of interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α and monocyte chemoattractant protein (MCP)-1 in LPS-stimulated RAW264.7 cells. Results also demonstrated that FM improved inflammatory response in LPS-stimulated A549 airway epithelial cells by inhibiting the production of cytokines, such as IL-1β, IL-6 and TNF-α. In addition, FM suppressed MAPK activation and NF-κB nuclear translocation induced by LPS. FM also upregulated the mRNA/protein expression levels of heme oxygenase-1 and the nuclear translocation of nuclear factor erythroid 2-related factor 2 in RAW264.7 cells. In an experimental animal model of LPSinduced acute lung injury, the increased levels of molecules in bronchoalveolar lavage (BAL) fluid were suppressed by FM administration. Collectively, it was founded that FM has anti-inflammatory properties on activated-macrophages by suppressing inflammatory molecules and regulating the activation of MAPK/ NF-κB signaling.

Sangmi Park,Soo Kyung Nam,이주영,전용훈 대한신생아학회 2018 Neonatal medicine Vol.25 No.3

Purpose: We aimed to evaluate the respiratory illness-related hospital visits (out-patient clinics, emergency room, and re-admission) of preterm infants, and compare them according to corrected age and prematurity. Methods: We reviewed the medical records of preterm infants born at <37 weeks of gestation admitted to the neonatal intensive care unit (NICU) at Inha University Hospital between January 2012 and June 2015. Infant follow-up appointments in both neonatology and pulmonology out-patient clinics occurred for at least 2 years after NICU discharge. Results: The proportion of infants who visited the hospital due to any respiratory illness was as high as 50% until 12 months of corrected age, and subsequently decreased over time. Hospital admission was significantly higher in early preterm infants (<34 weeks of gestation) compared to late preterm infants (≥34 and <37 weeks of gestation). The proportion of infants who were re-admitted due to lower respiratory tract illness was significantly higher until 6 months of corrected age compared to the later, and did not differ between early and late preterm infants. Conclusion: The proportion of hospital visits of preterm infants due to respiratory disease was high until 12 months of corrected age. Most notably, the re-admission proportion from lower respiratory tract illness was high under 6 months in both early and late preterm infants. Preterm infants within this age that are visiting the hospital with respiratory symptoms should be carefully observed and followed up.

Nonspecific protein labeling of photoaffinity linkers correlates with their molecular shapes in living cells

Park, Hankum,Koo, Ja Young,Srikanth, Yellamelli V. V.,Oh, Sangmi,Lee, Jiyoon,Park, Jongmin,Park, Seung Bum The Royal Society of Chemistry 2016 Chemical communications Vol.52 No.34

<P>Herein we report molecular shape-dependent nonspecific labeling of photoaffinity linkers (PLs) in the cellular proteome. Linear PLs have a greater tendency to engage in nonspecific binding than branched PLs. Exploiting this property, we discovered a smaller branched diazirine-based PL as the best photoaffinity probe with minimal nonspecific binding characteristics from among 5 probes with different PLs.</P>

한국 노인의 자서전적 기억 기능 연구 : Korean Version of Thinking About Life Experiences Scale의 개발과 활용

박상미(Sangmi Park),이창대(Chang Dae Lee),김태희(Tae Hui Kim) 대한노인정신의학회 2021 노인정신의학 Vol.25 No.2

Objective: The aim of this study was to develop a Korean version of the Thinking About Life Experiences (TALE-K) scale and to analyze the characteristics of autobiographical memory function (AMF) in community-dwelling older adults. Methods: To develop TALE-K, a translation and back-translation procedure followed by an understanding test was performed. Then, a survey was conducted to examine the associations of AMF with psychosocial variables using TALE-K, Index of Well-Being (IWB), Meaning in Life Scale for older adults, Revised UCLA Loneliness Scale, Medical Outcomes Study Social Support Survey, and Brief Resilience Scale. Results: Data from 75 community-dwelling older adults were used for the final analysis. The average scores of all three subscales of TALE-K were below 3 points (less frequent than occasionally). The correlation results showed that TALE-K total score was significantly associated with IWB and the Meaning in life scale for older adults. The multiple linear regression results presented that higher AMF was significantly associated with higher IWB, along with having siblings, higher meaning in life and resilience, and lower loneliness. Conclusion: Including a validation study of TALE-K, studies for understanding the characteristics of AMF in older adults using TALE-K are needed.

목적: 본 연구의 목적은 다양한 인지기능 수준을 가진 고령자를 위한 실감객체 기반 인지재활시스템을 개발하고,사용성을 검증하는 것이다. 방법: 사용성 연구는 시스템의 강점과 약점을 확인하기 위해 15명의 환자 집단과 4명의 작업치료사 집단에 설문조사를 실시하였으며 응답에 근거한 수정을 통해 시스템을 보완 및 개선하였다. 응답자들은 세 종류의 훈련-실행기능 훈련, 기억력 훈련, 집중력 훈련을 20분~30분간 경험해본 후, 구조화된 설문에 응답하였으며 설문의 영역은 각 훈련 영역별 콘텐츠, 중앙처리장치이자 화면 제시 매체인 태블릿 PC 및 실감객체를 포함하는 하드웨어, 시스템 이용에 따른 만족도로 구성되었다. 결과: 설문 응답 결과 환자 집단과 작업치료사 집단 모두에게 가장 흥미로웠던 영역은 실행기능으로 나타났고 가장 흥미롭지 않은 영역은 집중력으로 나타났다. 하드웨어 사용성 설문에서 태블릿 PC의 화면의 크기가 부적절하다는 응답이 6건, 실감객체의 크기가 부적절하다는 응답이 5건으로 나타났다. 시스템 이용에 대한 만족도 설문에서 전체 응답자의 40%가 시스템에 만족하는 것으로 응답하였다. 결론: 본 시스템은 훈련과제를 수행하기 위해 필요한 실감객체 도구의 조작이 용이하다는 점과 사용자의 요구에 따라 인지훈련의 영역을 쉽게 선택하여 훈련할 수 있다는 점, 사용자의 수행도에 의해 난이도가 자동으로 조정된다는 점을 특징으로 갖는다. 본 시스템에서 입력장치로 사용되는 실감객체도구는 양손에 쥐고 사용함 으로써 훈련환경을 자연스러운 일상에서의 도구 사용과 유사하도록 고안하였다. 본 시스템은 지역사회 인지 재활전문가 부족의 대안으로 사용가능 할 것으로 기대된다. Objective: To develop and verify the usability of a cognitive rehabilitation system with diverse cognitive functional levels based on tangible objects for the elderly population. Methods: A study was conducted to investigate the system s strengths and weaknesses by upgrading it with responses from two groups of 15 patients and 4 occupational therapists. After undergoing three forms of training - regarding executive function, memory, and concentration for a total of 20–30 min, the participants were asked to answer a structured questionnaire about contents of the three forms of training, hardware including the tablet PC functioning as a CPU and display media and tangible objects, and satisfaction of experiential usage of the system. Results: Both groups responded that the most interesting training area was executive function while the least interesting was concentration. Six participants reported that the size of the screen of the tablet PC was inappropriate, and five responded that the size of the tool was inappropriate. All therapists and 40% of the patients responded that they were satisfied with this system. Conclusion: This system’s features include easy manipulation of tangible tools for performing training tasks, easy selection of and training in cognitive areas based on users’ needs, and automatic adjustment of difficulty level based on users’ performance. The training environment was designed to be similar to the natural environment by using tangible objects in both hands as input devices for the system, and the system was considered as an alternative to the lack of community cognitive rehabilitation specialists.

박상미(Sangmi Park),우종정(Jongjung Woo) 한국정보기술학회 2009 Proceedings of KIIT Conference Vol.2009 No.-

IT 기술 발전은 일반 사용자에게 편리함을 제공할 뿐만 아니라 장애인에게도 영향을 미치고 있다. 장애인을 위한 IT 기술은 장애 종류에 따라, 오감, 가상현실, 또는 인지과학 등의 학문과 연계하여 발전하고 있다. 특히, 사고에 의해서 또는 선천적으로 눈만 움직일 수 있는 장애인들에게 효율적으로 컴퓨터와 상호작용할 수 있도록 눈을 이용한 시스템도 개발되었다. 그러나 이와 같은 시스템은 가격대가 높고, 효율적이지 못하다. 따라서 본 논문은 지체장애인들 또는 특정 질병을 겪고 있는 환자들의 정보 접근성 또는 의사소통의 질을 높이기 위하여 카메라로 입력된 눈 깜박임 영상을 단점(ㆍ)과 장점(-)으로 분류한 후 모르스 코드를 이용하여 컴퓨터 화면에 글자를 입력하고, 출력하는 시스템을 제안한다. 제안된 시스템을 통해 지체장애자, 감금 증후군 등의 심각한 질병을 겪고 있는 사람들이 자유롭게 의사소통을 전달할 수 있다 Advances in IT technologies not only make common people convenient but also have affected disabled persons for their lifes. IT technologies for disabled persons have developed in conjunction with five senses, virtual reality, and cognitive sciences. Especially, text input methods with eyes for those who have severe physical disability have been developed. Current devices which uses eye blinking patterns, eye tracking, or eye gaze automatically detect the duration of one's eye blinking pattern and are able people to type on their computer. However, current devices are not affordable for most of the people with physical disability. In addition, current devices have so many targets that some people have difficulty in using them. Thus, this paper suggests a text input method with eyes, which can reduce the number of targets so that disabled persons can be easy to type and make its costs less.

박상미(Sangmi Park),허경옥(Kyungok Huh) 한국소비문화학회 2012 소비문화연구 Vol.15 No.3

본 연구는 소비만족도를 증진시키기 위해서는 소비자의 소비욕구의 근거이자 판단의 기준이 되는 소비가치를 기반으로 한 소비행동이 이루어져야 한다는 관점에서, 소득계층에 따른 소비가치와 소비행동, 소비만족도 간의 관계를 비교하고 이를 통해 소비만족을 증진시킬 수 있는 합리적 소비행동에 대해 제시하고자 하였다. 주요 분석결과를 요약하면, 첫째, 소득계층별 분류에 따라 소비가치, 소비행동, 소비만족도 간의 관계를 분석한 결과, 상위소득계층의 경우 상황적 가치가 이성소비행동에 부적인 영향을 미치고, 인식적 가치가 감성소비행동에 정적인 영향을 미치는 것으로 나타났다. 하지만 이성소비행동과 감성소비행동 모두 소비만족도에는 영향을 미치지는 못 하였다. 둘째, 중위소득계층의 경우에는 정서적 가치와 인식적 가치 그리고 상황적 가치가 감성소비행동에 영향을 미치는 것으로 나타났으며, 기능적 가치와 인식적 가치, 상황적 가치가 이성소비행동에 영향을 미치는 것으로 나타났다. 또한 이성소비행동만이 소비만족도에 영향을 미치는 것으로 나타났다. 셋째, 하위소득계층의 경우에는 사회적 가치와 기능적 가치가 이성소비행동에 영향을, 미치고 사회적 가치와 정서적 가치가 감성소비행동에 영향을 미치는 것으로 나타났다. 그리고 이성소비행동과 감성소비행동 모두 소비만족도에 영향을 미치는 것으로 나타났다. In order to improve consumption satisfaction, reasonable consumer behavior based on consumption value which could be a basis of consumption needs and a yardstick for judgement of consumer should be established. This study analyze structural relationship between consumption value, consumption behavior and consumption satisfaction and also propose reasonable consumption behavior improving consumption satisfaction through comparing differences between consumption value, consumption behavior and consumption satisfaction by income class. The finding of results from analysis are summarized as follows. First, analysis for the structural relationship of consumption value, consumption behavior, and consumption satisfaction showed that functional value and conditional value had an influence on rational consumption behavior and epistemic value, while emotional value had an influence on emotional consumption behavior. Among these behaviors, only rational consumption behavior had a static influence on consumption satisfaction directly. Second, analysis for the relationship between consumption value, consumption behavior and consumption satisfaction by income classes showed that conditional value had a negative influence on rational consumption behavior and epistemic value had a static influence on emotional consumption behavior for the high income class. However, both rational consumption behavior and emotional behavior had no influence on consumption satisfaction. Third, for middle income class, emotional value, epistemic value and conditional value had an influence on emotional consumption behavior. And functional value, epistemic value and conditional value had an influence on rational consumption behavior. Only rational consumption behavior had an influence on consumption satisfaction. Fourth, for low income class, social value and functional value had an influence on rational consumption behavior. And social value and emotional value had an influence on emotional consumption behavior. Both rational consumption behavior and emotional consumption behavior had an influence on consumption satisfaction.
