Psychotherapy is an area of psychology that helps/treats people who are experiencing psychological and emotional difficulties by non-medical means. Psychotherapists build up theoretical backgrounds, profiles, and/or techniques to adequately assist clients and participants in the treatment of these disorders. Despite the fact that South Korea has a history of nearly 20 years in the field of bibliotherapy, there has not been a developed or proposed psychotherapy treatment model that suits many objectives and goals utilizing bibliotherapy. In this study, based on the person-centered counseling theory, we intend to develop a model and approach focusing on the clients-participants who are subject to bibliotherapy. This study will be the basis and reference for the development of bibliotherapy model(s) suitable for various psychological objectives and goals in the future as an alternative or in addition to other psychotherapy methods and techniques.

This study assessed the experience of telehealth digital art therapy with a phenomenological case study method based on the need for a psychotherapeutic intervention of caring for the psychological health of self-quarantined people before confirmed with COVID-19. The research participant was a 17-year-old adolescent (girl) from Canada, who participated in seven sessions in a structured telehealth digital art therapy program for 90~120 minutes per session while she was self-quarantining. The analysis of the data was conducted in the process of assessing significant statements through content analysis and drawing themes based on the researcher's pre-understanding and epoche. As a result, 34 themes were drawn, which were classified into 10 common theme clusters and finally into three theses, including "psychology and emotions during self-quarantine", "limitation of remote digital art therapy', and 'positiveness of remote digital art therapy." This study is the case study of telehealth digital art therapy conducted first with a self-quarantined person before confirmed with COVID-19, and at the center of the crisis of COVID-19, hopefully, this study would provide important implications for "psychological quarantine," active self-care for self-quarantined people's psychological health.

Microcapsules of two different self-healing agents, 5-ethylidene-2-norbornene (ENB) and ENB with a crosslinker, surrounded by a melamine-urea-formaldehyde shell were manufactured. In this work, a red dye was incorporated into the self-healing agents as a tracer for better visual observations. It revealed that the incorporation of a red dye into self-healing agents did not disturb the formation of microcapsules from the examination of thermal resistance, particle size/size distribution and morphology of the resulting microcapsules. Releasing of self-healing liquid into the induced crack from ruptured microcapsules and filling between crack planes were observed using an optical microscope. Also observed was the reaction of filled healing agent with embedded Grubbs' catalyst in an epoxy coating layer.

X-선 혹은 감마선 등 종래의 방서선 치료는 양성자 혹은 이온에 의한 치료방법의 등장함에 따라 퇴조할 것으로 보인다. 그 이유는, 양성자 등 전하를 띄는 입자치료기술이 치료 후 후유증이나 암의 재발을 현저히 억제시킬 수 있기 때문이다. 전하를 띄는 입자는 암 조직 전후의 정상 조직에 최소한의 피폭을 주나, X-선이나 감마선과 같은 광자들은 암 조직 전후의 정상세포가 암세포로 변화될 수 있는 정도의 피폭량을 주는 것으로 알려져 있다. 현재 임상 중인 양성자(혹은 극히 일부의 탄소이온 치료기)치료기는 1990년 미국의 로마린다(Loma Linda) 대학에서 최초로 건립된 방식인 사이클로트론 혹은 싱클로트론 가속기와 빔라인 및 겐트리(gantry)로 구성된다. 그 장치의 거대함만큼이나 가격과 유지비 등에서 일반 소형병원에서 운영하기에는 쉽지 않아 보인다. 이에 본고에서는 소형병원에서도 운영할 수 있는 저비용의 레이저 양성자(이온) 가속방식의 등장 배경과 향후 전망을 논하고자 한다.

Purpose: Aroma therapy is one modality of alternative medicine. It was well known to have an analgesic, antidepressive and anxiolytic effects. This study is designed to investigate the effect of aroma self hand massage on vital signs, pain, depression, anxiety and stress in breast cancer patients. Methods: 32 female patient over 20 years old were divided into two groups by a non-blinded randomized controlled method. Patient in the aroma group (n=15) massaged their hands twice a day using aroma oil by themselves in their home for 2 weeks. However, those in control group (n=17) had not received my intervention during the study periods. Pain intensity, state anxiety, depression and stress of subjects were evaluated three times (0, 1, 3 weeks) using Visual Analogue Scale (VAS, $0{\sim}10cm$), State Trait Anxiety Inventory (STAI), Beck Depression Inventory Scales (BDIS), Brief Encounter Psychosocial Instrument (BEPSI revised edition). Also the change of patients' accompanying symptoms after aroma massage were analyzed using a structured questionnaire. Results: Pain Intensity decreased in the aroma group compared with control group (VAS changes $-0.83{\pm}1.01\;vs\;0.38{\pm}0.86$, P=0.005). The numbers of accompanying symptoms (P=0.044), depression score (P=0.001) and anxiety score (P=0.008) were significantly decreased in the aroma group, while in control group they increased after 2 weeks. However, the stress score showed no significant changes in both groups ($0.05{\pm}0.85\;vs\;0.04{\pm}0.20$, P=0.1519). The depression, anxiety and stress score showed negative correlation with compliance of aroma massage, but statistically no significant. The systolic blood pressure was a little increased in aroma group ($4.53{\pm}14.43\;vs\;0.0{\pm}7.22$, P=0.026), but was not significant clinically. Patients in the aroma group complained of several symptoms such as headache (20%), paresthesia (6.75%) and nausea (6.7%). However, there were no drop-out patients for those side effects. Conclusion: Aroma self massage during two weeks in breast cancer patients alleviates the pain intensity, depression and anxiety significantly.

In the self-healing group key distribution scheme, users are capable of recovering lost group keys on their own without requesting additional transmission from the group manager, where there is no reliable network infrastructure. In this paper, we propose a new self-healing group key distribution scheme with revocation capability, which is optimal in terms of user memory storage and more efficient in terms of communication complexity than the previous results. We obtain a slightly improved result from (13) and (14) by using the new broadcasting method. In addition, we prove that our scheme has the properties of t-wise forward secrecy and t-wise backward secrecy, and extend this self-healing approach to the session key recovery scheme from a single broadcast message.

Internal derangement of the temporomandibular joint(TMJ) is defined as an abnormal relationship of the articular disc to the condyle. Mandibular manipulation is one of the conservative treatments to be considered first to manage the patients with anterior disc displacement without reduction. Mandibular manipulation is used to increase articular mobility and to restore the displaced disc into an anatomically normal position. While Farrar's technique has been popularly used, Minagi et al., Mongini and Suarez introduced the manipulation technique conducted by the patients themselves. But there is no study on the efficacy of self-manipulation technique, comparing with conventional one. The aim of this study was to investigate the efficacy of the conventional and self-manipulation technique, which was modified to complement the previously described technique by Minagi et al., in the treatment of patients with anterior disc displacement without reduction. TMD patients, who visited Department of Oral Medicine of Seoul National University Dental Hospital from December, 2002 to November, 2004 and were diagnosed as anterior disc displacement without reduction by TMJ magnetic resonance imaging (MRI) were enrolled. Conservative treatments including physical therapy, exercise, behavioral therapy, stabilization splint therapy, and manipulation therapy were done to every single patient until the symptomsimproved enough to discharge the patient. The charts were reviewed retrospectively according to the type of manipulation. In the results, patients whose maximum mouth opening was more than 40 mm was higher in the self-manipulation group(69.9%) than in the conventional manipulation group(42.9%). But difference between two groups was not significant. According to the fact that we decided to discharge the patients whentheir mouth opening increased to more than 40 mm and subjective symptoms such as pain and discomfort were improved as well, treatment period of discharged patients was significantly shorter in the self-manipulation group($29.2{\pm}12.3$ weeks) than in the conventional manipulation group ($61.0{\pm}38.0$ weeks) (p<0.01). In conclusion, in the treatment of TMD patients with anterior disc displacement without reduction, the self-manipulation technique which is performed by patients themselves is an effective treatment modality for increasing the range of mouth opening and shortening the total treatment period.
