Online social networks (OSNs) have changed the way people communicate with each other. An OSN usually encourages the participants to provide personal information such as real names, birthdays and educational background to look for and establish friendships among them. Some users are unwilling to reveal personal information on their personal pages due to potential privacy concerns, but their friends may inadvertently reveal that. In this work, we investigate the possibility of leaking personal information on Facebook in an unintentional and involuntary manner. The revealed information may be useful to malicious users for social engineering and spear phishing. We design the inference methods to find birthdays and educational background of Facebook users based on the interactions among friends on Facebook pages and groups, and also leverage J-measure to find the inference rules. The inference improves the finding rate of birthdays from 71.2% to 87.0% with the accuracy of 92.0%, and that of educational background from 75.2% to 91.7% with the accuracy of 86.3%. We also suggest the sanitization strategies to avoid the private information leakage.

This study has been performed to review critical issues affecting continuous residence in profit(self-paid) assistant living facilities for the elderly in the United States. There are three factors influencing continuous residence of frail elderly in the facilities as long as they want without involuntary discharge : Financial ability, behavioral aspects, and facility management situation. Regarding financial ability, income, purchase of insurance policy, cashable assets, willingfulness to pay, and health status were found to be crucial determinants of continuous residence. Overall, 40-50% of those aged 65+ are financially able to stay in the assistant facilities as long as they want, without involuntary discharge. As for behavioral aspects, extroversions, congeniality, culture & life style, conscientiousness, preference for person, and physiological habits were found to be crucial determinants of continuous residence. As for the management situation, it is essential that facilities reach nature level of self-governing rights of the older residents and good local images, and conflicts among the residents and managing parties be resolved on the agreeable standards of inspectors. finally in this study, it is proposed that in Korea, national pension authority offer a liability package for assistant residence, for the case of individual bankruptcy.

COVID-19 vaccines have been developed worldwide in order to prevent the spread of coronavirus infection-19, but some people tend to refuse to be vaccinated against COVID-19. Therefore, we will investigate how people's understanding of COVID-19 vaccines affects their attitude to accept COVID-19 vaccination information. Therefore, the purpose of this study is to examine the determinants that affect the acceptability of COVID-19 vaccine through the informational characteristics of COVID-19 vaccine and the individual health belief theory. This study conducted an offline survey of 215 adult men and women living in Seoul and Gyeonggi-do Province during the period from September 1 to September 10, 2022, and we have conducted a final analysis using a total of 212 questionnaires. The results of our study were as follows. First, among the information characteristics of COVID-19 vaccine, it was confirmed that the amount of information had a significant positive effect on susceptibility, severity, and barriers in health belief theory, respectively. Second, among the information characteristics of COVID-19 vaccine, it was found that the quality of information had a significant positive effect on the susceptibility in health belief theory. Third, susceptibility and barriers in the health belief theory significantly had a positive effect on voluntary attitude and involuntary attitude in acceptance attitude, respectively. And finally, it was found that the severity of the health belief theory had a positive effect on the involuntary attitude in acceptance attitude. The results of this study suggest that policy efforts are needed to make accurate information about COVID-19 vaccine known to the people.

Purpose: This study systematically analyzed cases in South Korea wherein nurses were prosecuted for involuntary manslaughter or injury due to professional negligence in pediatric care. Methods: We analyzed the precedents using the methodology of Hall and Wright (2008) and Austin (2010). Of the 618 cases retrieved from the Supreme Court Decisions Retrieval System in South Korea, we selected the 12 cases in which children were the victims and nurses were the defendants, using a case screening methodology. Results: The most frequent penalty was a fine, and newborns were the most frequent victims. The distribution of cases according to Austin's violation categories was: improper administration of medications (n=5), failure to monitor for and report deterioration (n=4), ineffective communication (n=4), failure to delegate responsibly (n=4), failure to know and follow facility policies and procedures (n=1), and improper use of equipment (n=1). Conclusion: To ensure the safety of children, nurses are required to teach and practice a high standard of care. Nursing education programs must improve nurses' awareness of their legal obligations. Nursing organizations and leaders should also work towards enacting effective nursing laws and ensuring that nurses are aware of their legal rights and responsibilities.

Drug-induced dyskinesia is an involuntary muscle movement caused by various dopamine receptor-blocking drug exposure, such as antipsychotics, antidepressants, and antiemetics. Causative drug removal is the main treatment for drug-induced dyskinesia whenever possible because its pathophysiology lacks a universally accepted mechanism; however, the symptoms can persist for years or decades in many patients even after causative drug removal. Herein, we present a case of drug-induced dyskinesia in a 61-year-old female patient who consumed medication for approximately 10 years for her depression, anxiety, and insomnia. Cervical and facial dyskinesia was suggested to be related to perphenazine and levosulpiride administration. The patient received acupuncture, pharmacopuncture, herbal medicine, and chuna treatment for 81 days during hospitalization. The symptoms were evaluated using the Abnormal Involuntary Movement Scale, Toronto Western Spasmodic Torticollis Rating Scale, Tsui's score, and Numeric Rating Scale, which revealed remarkable improvement, suggesting the effectiveness of combined Korean medicine for drug-induced dyskinesia.

Objective : The parafascicular nucleus (PF) plays important roles in controlling the basal ganglia. It is not well known whether the PF affects the development of abnormal involuntary movements (AIMs). This study was aimed to find a role of the PF in development of AIMs using optogenetic methods in an animal model. Methods : Fourteen rats were underwent stereotactic operation, in which they were injected with an adeno-associated virus with channelrhodopsin (AAV2-hSyn-ChR2-mCherry) to the lateral one third of the PF. Behavior test was performed with and without optical stimulation 14 days after the injection of the virus. AIM of rat was examined using AIM score. After the behavior test, rat's brain was carefully extracted and the section was examined using a fluorescence microscope to confirm transfection of the PF. Results : Of the 14 rats, seven rats displayed evident involuntary abnormal movements. AIM scores were increased significantly after the stimulation compared to those at baseline. In rats with AIMs, mCherry expression was prominent in the PF, while the rats without AIM lacked with the mCherry expression. Conclusion : AIMs could be reversibly induced by stimulating the PF through an optogenetic method.

본 연구는 장애의 특성상 인권보장이 '다수의 안전'이나 '치료적 이득'과 갈등이 있을 수밖에 없는 정신장애인의 인권 보장과 제한을 일반적으로 어떻게 이해하는지를 알아보고자 하는 것이다. 따라서 일반인 10명, 전문가 9명, 정신장애인 6명을 대상으로 각 권리(존엄성 존중, 차별대우 받지 않을 권리, 자발적 입원보장, 자유로운 환경보장)별로 문제영역(장기입원, 운전면허취득제한, 강제입원, 통신의 자유제한)을 구체화하여 면담하였다. 면담내용을 질적 분석한 결과 조사대상자들이 권리보장과 제한을 이해하는 두 가지 차원을 발견하였다. 첫 번째 차원은 권리보장과 제한을 다수에 미치는 긍정적 결과를 중심으로 정당화하느냐 아니면 인권존중의 보편적 원리를 내세워 권리중심으로 정당화하느냐 하는 것이다. 두 번째 차원은 권리보장과 제한의 판단주체를 공식적 체계에 두느냐 아니면 비공식적 체계에 두느냐 하는 것이다.

본 연구는 우리나라 대기업 중년 남성 임원들의 비자발적 퇴직 이후 성공적인 적응을 위한 심리적·사회적 요인들을 알아보았다. 이를 위하여 퇴직 임원 13명(남성, 평균 58.2세)을 대상으로 퇴직 이후 시간의 경과에 따른 변화 경험과 이에 대한 평가나 해석에 대해 심층면담하고 그 내용을 현상학적 방법으로 분석하였다. 그 결과, '경제적 준비'와 '배우자 지원'이 적응 선행요건이었다. 적응 과정에서 출발점은 '현실 수용'으로, 과거 삶의 재평가, 다양한 변화들을 인정하고 과거에서 탈피, 평범한 50대 퇴직자로서 자신의 모습을 수용, 불안과의 동거, 적절한 시간의 필요 등의 하위요소로 구성되었다. 그 다음 이들은 인지적·정서적 재평가와 삶의 가치를 재정비하고, 일의 의미와 목표를 재구성하면서 미래를 설계했으며, 새로 선택한 활동들을 중심으로 '심리적 재구조화'와 '자아정체성'을 재정립했다. 이들의 퇴직과 퇴직 후 적응은 심리적·사회적 자본이 충족되었던 임원 재직 경험에 대한 대립과정이자, 이로 인한 부적응적 대처 양상에 대한 스토리이며, 이후 인지·정서·행동 차원에서 이러한 부조화를 극복해가는 일련의 과정에 대한 서사였다. 본 연구결과는 기업이나 국가 그리고 퇴직자에게 퇴직에 대한 대처와 관련하여 시사점을 제공한다.
