We evaluated clinical efficacy and acceptability of transdermal estradiol patch treatment (beta estro, 1 mg/patch) in 30 patients with hot flushes and/or postmenopausal syndrome. 26 of 29 patients with hot flushes and 1 patient with postmenopausal syndrome were found to experience the improvement of symptoms. 1 of 3 patients who did not experience clinical improvement with patch treatment experienced the improvement of urinary symptoms and headaches. Among 3 of 26 patients who experienced improvement in hot flushes, 1 patient sufferes aggravation of headache and 2 patients complained generalized myalgia and dysphoria during treatment. 1 patient whose symptoms had not improved was the one who had the history of skin allergy against plasters and suffered the severe irritation symptoms at the sites of patch application and stopped the patch trement at 10th day of trial. The other 29 did not complain any side effects other than mild skin hyperemia at the site of plaster contact. 25 patients agreed that estradoil (beta estro 1 mg/patch) treatment for two weeks were "effective: in the amenlioration of their postmenpausal symptoms. The above findings showed that the trasdermal estradiol patch treatment improved severity scroes of hot flushes and symptoms of postmenopausal syndrome. Any significant side effect to stop the treament was not observed for 2 weeks of treament and the ratio (83%) of the subjective "effective" group with transdermal estradiol therapy suggessted that this modality might be an alternative of estrogen delivery for longterm treatment in patients with hot flushes and postmenopausal syndromes.

Objectives : This article aims to describe the development of smartphone application for the case management of patients with schizophrenia. Methods : Gwangju Bukgu-Community Mental Health Center developed and launched a smartphone application (HYM) for cognitive-behavioral case management and symptom monitoring. The development of the application involved psychiatrists, nurses, social workers, psychologists, and software technicians from a software development company (Goosl Corp.). Results : The HYM application for clients includes six main modules including Thought record, Symptom record, Daily life record, Official notices, Communication, and Scales. The key module is the ‘Thought Record’ for self-directed cognitive-behavioral treatment (CBT). When the client writes and sends the self-CBT sheet to the case manager, the latter receives a notification and can provide feedback in real time. ‘Communication’ and ‘Official notices’ are useful for promoting communication between case managers and clients with schizophrenia. Ratings in ‘Symptom record’, ‘Daily life record’, and ‘Scales’ modules are stored in graphic or table form representing changes in them and shared with case managers. Conclusion : The interactive function of this application is the key characteristics that distinguishes it from other mobile self-treatment tools. This smartphone application may contribute to the development of a youth- and customer-friendly case management system for individuals with early psychosis.

No-fines concrete is concrete from which the fine aggregate fraction has been omitted. The concrete so formed, consisting only of coarse aggregate, cement, and water, has large voids uniformly distributed through its mass. This study was performed to obtain the basic data which can be applied to the use of no-fines concrete. The data was based on the properties of no-fines concrete depending upon various mixing ratios. The results obtained were summarized as follows. 1. Test result of the consistency, suitable water-cement ratio was increased with the increasing of mixing ratio. 2. At the suitable water-cement ratio, the highest strengths were showed. But it gradually was decreased with the increasing of mixing ratio and strengths are considerably lower than that of conventional portland cement concrete. 3. The relations between compressive and tensile strength were highly singnificant as a straight line shaped. The strength ratio was decreased with the increasing of mixing ratio and considerably lower than of conventional portland cement concrete. 4. Bulk density was decreased with the increasing of the mixing ratio, and was similar to that of the conventional portland cement concrete at mixing ratio 1:4. 5. The relations between strength and bulk density were highly significant as a straight line shaped. The decreasing ratio of strengths was higher than that of bulk density.

이 연구(硏究)는 조기강도증진(早期强度增進)을 위한 목적(目的)으로 염화칼슘, 조강감수분산제(早强減水分散劑), 증기양생(蒸氣養生) 온도별(溫度別)로 구분하여 콘크리트의 강도특성(强度特性)을 보통시멘트 콘크리트와 비교(比較)하여 그 성질(性質)을 구명(究明)함으로써 콘크리트의 효율적인 사용(使用)을 위한 기초자료(基礎資料)를 마련하는데 있으며, 이 연구(硏究)에서 얻어진 결과(結果)를 요약(要約)하면 다음과 같다. 1. 조강감수분산제(早强減水分散劑)는 최적정 첨가량인 시멘트 중량의 0.75% 첨가량에서 10%정도의 감수효과(減水效果)를 보였으나, 염화칼슘은 물-시멘트비(比)에 영향을 거의 미치지 않았다. 2. 압축(壓縮) 및 인장강도(引張强度)는 보통시멘트 콘크리트에 비하여 염화칼슘은 시멘트 중량의 2.0%에서 125%, 143% 조강감수분산제(早强減水分散劑)는 시멘트 중량의 0.75%에서 120%, 140% 최대강도(最大强度)를 나타내었으며 그 이상 첨가하면 강도가 저하하는 경향을 보였다. 3. 증기양생(蒸氣養生)에서 $60^{\circ}C$ 양생시의 경우에는 재령(材齡)이 증가함에 따라 강도의 증가현상을 보였으나, $100^{\circ}C$ 양생시 재령(材齡) 1(일)日에서는 보통시멘트 콘크리트보다 2배(培)정도의 강도증가를 나타내었고 재령(材齡) 7일(日) 이후에는 보통시멘트 콘크리트와 비슷한 강도증가(强度增加) 현상(現象)을 보였다. 4. 보통시멘트 콘크리트, 염화칼슘 및 조강감수분산제(早强減水分散劑)를 첨가한 콘크리트와 증기양생(蒸氣養生)을 한 콘크리트의 압축(壓縮) 및 인장강도(引張强度)와의 상관성을 검토한 바 직선형으로 나타났으며 각각 고도의 유의성(有意性)이 인정되었다. This study was performed to obtain the basic data which can be applied to improve the early strength of concrete. The results obtained were as follows; 1. In case that water reducing-set accelerating agent was added 0.75% of the weight of cement, the weight of water was reducd 10%. And $CaCl_2$ did nearly not have an effect on the w/c ratio. 2. Compressive strength and tensile strength increased 25%, 43%, respectively, in case that $CaCl_2$ was 2.0% of the weight of cement, and showed 120%, 140%, respectively, in case that water reducing-set accelerating agent was 0.75% of the weight of cement. 3. In case of steam curing at $60^{\circ}C$, the strength increased with the ages. At $100^{\circ}C$, the increase of strength in 1 age was two times as compared with plain concrete. After 7ages, the strength was similer to plain concrete. 4. The relationship between compressive strength and tensile strength was linear and was highly significant in cases of plain concrete, $CaCl_2$ concrete, C-W concrete, steam cured concrete, respectively.

김성완,장지은,이주연,이가영,유혜영,박철,강희주,김재민,윤진상 대한신경정신의학회 2017 PSYCHIATRY INVESTIGATION Vol.14 No.5

Objective: To develop a model of group cognitive-behavioral therapy (CBT) for Korean patients with early psychosis. Methods: The group CBT utilized in the present study consisted of metacognitive training, cognitive restructuring, and lifestyle managements. The Subjective Well-being Under Neuroleptics (SWN-K), Ambiguous Intentions Hostility Questionnaire (AIHQ), Drug Attitude Inventory (DAI), Beck Depression Inventory (BDI), Perceived Stress Scale (PSS), and Clinical Global Impression (CGI) were administered prior to and after CBT sessions. The participants were categorized into two groups according to the median duration of untreated psychosis (DUP; 4 months). Results: A total of 34 patients were included in this analysis. From pre- to post-therapy, there were significant increases in the SWN-K and DAI scores and significant decreases in the hostility subscale of the AIHQ, PSS, and CGI scores. Significant time × DUP interaction effects were observed for the SWN-K, DAI, and BDI scores, such that there were significant changes in patients with a short DUP but not in those with a long DUP. Conclusion: The group CBT program had a positive effect on subjective wellbeing, attitude toward treatment, perceived stress, and suspiciousness of young Korean patients with early psychosis. These effects were particularly significant in patients with a short DUP.

COVID-19 유행 시기의 조현병 환자 지원

김성완 대한조현병학회 2021 대한조현병학회지 Vol.24 No.2

The coronavirus disease 2019 (COVID-19) pandemic has drastically impacted our society and health care system. People with schizophrenia are more vulnerable to this burden of illness and related societal changes. In addition, they are more susceptible to the transmission of COVID-19 and have a significantly higher mortality rate compared to the general population. In a recent study, vaccinated patients with schizophrenia showed a greatly decreased mortality level similar to that of the general population. However, patients with schizophrenia were less likely to be vaccinated. Mental health professionals should provide them with appropriate information on prevention strategies against COVID-19 and vaccination. Long-lasting social distancing and social disconnection can make people with schizophrenia more vulnerable to loneliness and depression. Furthermore, patients with schizophrenia may face challenges continuing psychiatric treatment due to the COVID-19 pandemic. Social support and suitable mental health services using novel technologies should be developed and provided to patients with schizophrenia.

뻬뜨루솁스까야 산문의 문체적 특징 고찰

김성완 한국외국어대학교 외국문학연구소 2011 외국문학연구 Vol.- No.43

The purpose of this study is to analyze the literary style of Lyudmila Petrushevskaya, a Russian woman writer who takes a crucial position in contemporary Russian literature against a backdrop of general linguistic aspects appearing in contemporary Russian prose. It is advisable that studies on literary style should inevitably involve analysis on the functions and effects of style instruments that reveal any theme of a literary work from the macroscopic perspective with a view to following up the world view of author as revealed in his or her work. Based on a discussion that a style refers to a theme from the above standpoint, this study is focused upon how any linguistic form and content was revealed with style in works of Petrushevskaya becomes consistently unified with each other. Chapter 1 made a general examination into linguistic aspects shown in contemporary Russian prose, and Chapter 2 sought to make a further analysis on Petrushevskaya's short novel titled From the Mountain on the basis of discussions in preceding chapter. Here, it was most noticeable how narrator's viewpoint is expressed through frequent use of dissonant styles and insertion. At the same time, this study exemplified actual cases that style instruments of From the Mountain, a work of Petrushevskaya under analysis were used again for her other work, so that it sought to understand general characteristics of her literary styles. 본 논문은 현대러시아 산문에 나타나는 전반적인 언어적 양상을 배경으로 현대러시아 문학에서 중추적인 위상을 차지하고 있는 류드밀라 뻬뜨루솁스까야의 작품에 나타난 문체의 특징을 분석한 것이다. 문체연구는 작품에 드러난 작가의 세계관을 규명하고자 하는 거시적 측면에서 작품의 주제를 드러내는 문체적 장치들의 기능과 효과에 대한 분석을 필연적으로 수반해야 할 것이다. 이와 같은 입장을 토대로 본 논문은 문체가 곧 주제라는 논의에 입각하여 뻬뜨루솁스까야의 작품에서 문체로 드러나는 언어 형식과 내용이 어떻게 통일되어 있는가에 분석의 초점을 맞추었다. 본 논문의 두 번째 장에서는 현대러시아 산문에 나타나는 언어적 양상을 개괄적으로 살펴보고 있으며, 세 번째 장에서는 앞장에서 살펴본 내용들을 토대로 뻬뜨루솁스까야의 단편, 「산으로부터」의 세밀한 분석을 시도하였다. 이때 무엇보다 주목한 것은 문체적 불협화음과 삽입구문의 빈번한 사용을 통해 서술자의 관점이 어떻게 표출되고 있는가 하는 것이다. 이와 동시에 분석 대상이 된 작품에 나타난 문체적 장치들이 다른 작품에서도 반복되는 경우들을 예시함으로써 본 논문은 뻬뜨루솁스까야의 문체가 가지는 전반적인 특징에 대한 이해를 도모하고 있다.
