The green algae Scenedesmus acuminatus was cultured in different media: animal wastewater and an artificial culture medium in order to evaluate potential use for tertiary treatment. The experiments were conducted with air flowrate 1~2 L/min at $28{\sim}30^{\circ}C$. The nitrogen and phosphorus showed very similar removal efficiencies (68~77 % and 69~80 % for nitrogen and phosphorus respectively). The optimal fed period was estimated as three days in the semi-continuous experiment. The effects of $CO_2$ (4.5 %) injection on nutrient uptake from animal wastewater (biological treatment effluent) were compared to an air injection under the same conditions of light and photoperiod. The uptake rates of nutrient with air injection were observed 0.009 gN/gChl-a/day, 0.028 gN/gChl-a/day and T-P 0.003 gP/gChl-a/day for nitrate, total nitrogen and phosphorus respectively. The rates were enhanced by addition of $CO_2$ to 0.026 gN/gChl-a/day, 0.076 gN/gChl-a/day and T-P 0.018 gP/gChl-a/day. This study establishes that $CO_2$ addition during nutrient deprivation of microalgal cells may accelerate tertiary wastewater treatment.

Gingival recession is clinically manifested by an apical displacement of the gingival tissue and dentin hypersensitivity is often used to describe a painful condition in which exposed dentin is unduly sensitive to intraoral stimuli. The objects of this study were primarily to investigate the prevalence and distribution of gingival recession and hypersensitivity and secondarily to determine whether a relationship exists between gingival recession and hypersensitivity. The study population was 195 patients (102 males, 93 females) who were attended the department of periodontology, Pusan National University Hospital. 189 patients exhibited gingival recession at least more than 1 tooth, the prevalence was 96.9%. The maxillary and mandibular first premolar and mandibular incisors had the highest prevalence. The majority of patients (139 patients, 71.3%) were diagnosed as having dentin hypersensitivity. Dentin hypersensitivity was determined to 3 seconds application of cold air to the exposed root surface after isolating the test tooth and was commonest in maxillary and mandibular first premolars and mandibular incisors. Relationship between recession and hypersensitivity was analyzed using chi-square test (p=0.05), significant relation (p=0.000) was existed. Gingival recession was more severe, the prevalence of hypersensitivity was higher.

Objective : Recently, many studies have showed the evidences of the effect of acupuncture treatment through scientific methods. We performed electro-acupuncture on Taixi(K3) and observed the change of brain activity using fMRI. Methods : To see the effect of electro-acupuncture stimulation on Taixi(K3), the experiment was carried out on twelve healthy volunteers, using the gradient echo sequence with the 3.0T whole-body fMRI system(ISOL). After the needle insertion on K3, 2 Hz of electric stimulation was given for 30 seconds, repeated five times, with 30 seconds' intervals. Result & Conclusions : Unilateral electro-acupuncture stimulation on K3 increased the brain activity in Brodman Area 8, 6, 9, 13, 21, 22, 38, 40, 43, 2, 5, 10, 20, 24, 32, 34, 37, 39, 41, 42. and decreased the brain activity in Brodman Area 9, 13, 38, 22, 31, 3, 6, 10, 21, 25, 29, 30. Group Averaged Brain activity induced by Unilateral Electro-acupuncture Stimulation on K3 was increased in Brodman Area 10, 22, 42, 43, 44 and was decreased inn Brodman Area 6 and pyrogen test of Bee venom. Bilateral electro-acupuncture stimulation on k3 increased the brain activity in Brodman Area 22, 3, 19, 4, 13, 17, 21, 41, 42, 2, 5, 6, 7, 18, 23, 29, 30, 31, 40 and decreased the brain activity in Brodman Area 18, 6, 39, 4, 13, 2, 10, 19, 36, 40, 45, 46, 47. Group Averaged Brain activity induced by Bilateral Electro-acupuncture Stimulation on K3 was increased in Brodman Area 22, 13, 4, 3, 29, 38, 43 and was decreased in Brodman Area 18, 3, 19, 22, 39. Motor Stimulation activated Brodmann Area 6, 43, 18.

Background: AMP-activated protein kinase (AMPK) is a serine/threonine protein kinase that plays a pivotal role in the balance of cellular energy metabolism. Recent studies have reported that AMPK has numerous roles in physiological conditions, and dysregulation of AMPK induces pathological processes and diseases. However, the role of AMPK and its activators have not yet been studied in the context of hair growth regulation. Objective: To investigate the effects of metformin on dermal papilla (DP) and outer root sheath (ORS) cells, as well as the role of the AMPK pathway in hair growth. Methods: We evaluated whether metformin, a well-known AMPK activator, had any beneficial effects on hair growth. In addition, to evaluate the molecular and cellular mechanisms that were involved, protein levels of AMPK and β-catenin were analyzed. Results: Metformin increased the cellular proliferation of human DP and ORS cells. Ki-67 expression was also significantly increased after metformin treatment in the ex vivo hair follicle organ culture. Furthermore, DP and ORS cells treated with metformin had a significant increase in AMPK phosphorylation, which in turn suppressed β-catenin degradation and enhanced its nuclear accumulation. Conclusion: We demonstrated that metformin promoted hair growth via the AMPK/β-catenin signaling pathway in vitro with DP and ORS cells. The hair-promoting effects of AMPK activators may potentially be used for the treatment of alopecia, and further investigation will be needed in the future. (Korean J Dermatol 2019;57(4):175∼ 181)

박기영(Ki-Young Park),박경애(Kyung-Ae Park) 한국REBT인지행동치료학회 2022 한국REBT인지행동치료 Vol.2 No.2

현재 경찰의 비행청소년 선도프로그램은 구체적인 내용 및 실시방법이 마련되지도 않았고 비행청소년의 재비행 예방에 효과가 있다는 것도 검증되지 않았다. 본 연구는 경찰단계에서 내실 있는 선도프로그램을 설계하고 표준화하기 위해 합리적정서행동치료(Rational Emotive Behavior Therapy) 이론을 기반으로 경찰 선도프로그램 개발하고 그 효과를 검증을 목표로 하고 있다. 선행연구를 통해 확인한바 청소년 비행에 영향을 미치는 대표적 정서적 요인은 우울과 불안이었으며 자아존중감은 재비행을 낮출 수 있는 보호요인으로 기능하고 있었다. 이에 합리적정서행동치료의 인지적, 정서적, 행동적 기법을 적용한 3일 10시간의 경찰 선도프로그램을 구성하였다. 연구대상은 N경찰서에 형사입건 된 비행청소년 18명이며 연구대상자들과 같은 수의 연구자들이 개인상담, 그룹활동, 집단상담 프로그램을 진행하였고 우울, 불안, 자아존중감 척도에 대한 사전, 사후, 추후 검사를 실시하였다. 연구결과 우울과 불안은 사후와 추후 모두 유의미하게 감소되었고 자아존중감은 사후만 유의미하게 향상되었다. 이는 비행청소년이 비합리적인 신념을 합리적인 신념으로 전환하려는 노력이 우울과 불안 그리고 자아존중감에 영향을 미쳐 재비행을 예방할 수 있음을 시사한다. 후속연구를 통해 담당자가 프로그램을 쉽고 편하게 진행할 수 있고 청소년이 안전하게 참여할 수 있는 세부적인 매뉴얼 개발을 제언한다. Currently, the police guidance program for juvenile delinquents has not been specific and implemented, and it has not been verified that it is effective in preventing juvenile delinquency again. The purpose of this study is to develop a police guidance program based on the Rational Emotive Behavior Therapy and verify its effectiveness in order to standardize a substantial guidance program at the police level. Through previous studies, representative emotional factors affecting juvenile delinquency were depression and anxiety, and self-esteem was functioning as a protective factor that could lower delinquency. A 3-day, 10-hour police guidance program was constructed that applied cognitive, emotional, and behavioral techniques of Rational Emotive Behavior Therapy. The subjects of the study were 18 juvenile delinquents criminally reported to N Police Station, and the same number of researchers conducted personal counseling, group activities, and group counseling, and pre-, post-, and follow-up examination on depression, anxiety, and self-esteem measures. As a result of the study, depression and anxiety significantly decreased in the post-, and follow-up examination, and self-esteem significantly improved only in the post-examination. This suggests that juvenile delinquents' efforts to convert irrational beliefs into rational beliefs can affect depression, anxiety, and self-esteem and prevent juvenile delinquency. Through follow-up research, it is suggested that the person in charge can easily and comfortably proceed with this program and that juvenile delinquents can participate safely.

N/A A batch test and phosphorus release model were developed to evaluate biological phosphorus removal of the intermittent decant extended aeration process. Wastewater used in this study was estimated to be available for biological phosphorus release by using the batch test criteria. Specific release rate (SRR) for phosphorus was 0.031㎎-P/g-VSS·min in case of wastewater and it increased to 0.047㎎-P/g-VSS·min with acetic acid addition. As a result of the batch test, wastewater from Kwangdong-ri was applicable to a EBPR (enhanced biological phosphorus removal) process. Phosphorus release model could availably estimate concentration of effluent phosphorus using parameters from the batch test. However, it is difficult to predict accurately in case of large variation of influent concentration.

동성애자의 인지왜곡에 대한 진리요법적 접근

박기영 ( Ki Young Park ) 한국복음주의신학회 2015 성경과신학 Vol.76 No.-

본 연구의 목적은 동성애자의 인지왜곡을 진리요법적 접근으로 논박하여 성경적 사고로 변화시키는데 있다. 진리요법이란 진리의 근원인 하나님의 말씀을 근거로 인간의 내면에 형성된 인지왜곡을 재구성하여 변화시키는 기독교 상담의 한 모델이다. 서론에서는 동성애의 정의와 원인 및 선행연구에 대한 고찰을 했고, 본론에서는 성경에서 동성애를 바라보는 개신교계 상반된 해석의 차이를 살펴본 후에 동성애자의 인지왜곡을 변화시키기 위해 진리요법을 적용했다. 연구자는 동성애자의 인지왜곡을 다음과 같이 분류했다. (1) “동성애는 치료가 불가능한 질병이다.” (2) “성경은 동성애를 죄라고 말하지 않는다.” (3) “하나님은 사랑이시므로 나를 받아주실 것이다.” (4) “성(性) 정체성에 대한 선택은 나에게 있다.”기독교상담자는 동성애자의 인지왜곡을 진리요법의 논박을 통해 다음과 같이 인지재구성을 할 수 있다고 보았다. (1) “동성애는 고칠 수 있는 질병이다.” (2) “동성애는 죄이며, 하나님의 심판이 있다.” (3) “하나님은 나를 사랑하지시만 죄는 회개해야 한다.” (4) “성 정체성은 하나님이 결정해야 할 사항이다.”그러나 동성애의 죄는 영적인 문제이기 때문에 성령의 도우심이 있어야 하므로, 기독교상담자는 영적으로 깨어 있어야 한다. 또한 기독교상담자는 동성애자를 정죄하기보다는 주님의 사랑으로 바라보면서 그들도 구원의 대상임을 인식하면서 접근해야 할 것이다. This study looks into the cognitive distortion of homosexuals focusing on the Truth-therapy and changes the distortion to biblical thinking. As for how to describe the Truth-therapy, it is regarded as one of the models used in Christian counseling which would basically use the words of God for rationally changing any cognitive distortion that had been formed inside human begins. In the introduction, the study discussed definitions and causes of homosexuality as well as these other advance researches on the topic and then, dealt with differences in conflicting interpretations that Protestantism had offered on how the Bible would recognize the homosexuality. The body of the study applied the Truth-therapy to make changes in the cognitive distortion of the homosexuals. The researcher of this study understood the cognitive distortion of the homosexuals as follows. (1) “The homosexuality is a disease that can never be cured.” (2) “The Bible does not say that the homosexuality is a sin.” (3) “God will accept me because he is the love.” (4) “I have a right to choose my sexual identity.” The study believes that Christian counselors can make their own arguments on such cognitive distortion and help cognitive reconstruction in the following manner. (1) “The homosexuality is a disease that can be cured.” (2) “The homosexuality is a sin and, I will be judged by God for that.” (3) “God loves me but, I still must repent of my sin.” (4) “It is God who chooses my sexual identity.” However, the sin of the homosexuality is regarded as a spiritual issue and, the mercy of the Holy Spirit is an essential for the change in such thinking. That is why the Christian counselors should be always spiritually awake. In addition, the Christian counselors need to approach and accept the homosexuals as targets of salvation as concentrating on the love of God rather than forcing the homosexuals on purgation.
