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.

박기영,임병란,이기세,이수구,Park, Ki-Young,Lim, Byung-Ran,Lee, Ki-Say,Lee, Soo-Koo 한국농공학회 2011 한국농공학회논문집 Vol.53 No.1

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.

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)

The simultaneous existence of intrauterine and extrauterine pregnancies is known as a heterotopic pregnancy. Spontaneous heterotopic pregnancy is a rare event although its incidence has increased since the recent development of treatment of infertile women with ovulation induction or in-vitro fertilization and embryo transfer(IVF-ET).The theoretical rate of this condition was estimated to be approximately 1 in 30,000 pregnancies. The early diagnosis of heterotopic pregnancy is very difficult . So there is a high maternal morbidity and fetal loss. We reported a IVP - ET patient resulting in the successful delivery of live infant at 35weeks of gestational age from intrauterine pregnancy following surgical removal of ruptured concurrent extrauterine pregnancy.

심리학 개방성에 따른 기독교상담의 성향

박기영 ( Park Ki Young ) 한국복음주의 기독교상담학회 2007 복음과 상담 Vol.8 No.-

기독교상담은 상담자의 신학적, 심리학적 배경에 따라서 그 성향이 다르며, 기독교상담의 성향을 결정짓는 요인도 다양하다. 본 연구에서는 기독교상담의 성향을 결정하는 요인 가운데 하나로 상담자의 심리학에 대한 개방성으로 보았다. 본 연구자는 기독교상담자의 심리학 개방성에 따라 기독교상담의 유형을 다음과 같이 다섯 가지 유형으로 분류했다. 첫째, 개방유형이다. 이는 상담자가 심리학에 대해서 열린 자세를 취하기 때 문에 기독교상담에서 성경이나 신학적인 자료를 활용하는 데는 관심이 없다. 심리학을 신뢰한다는 측면에서 인본주의적이며, 기독교상담이라고 하기에는 무리가 있다. 둘째, 수용유형이다. 이는 상담자가 심리학을 받아들이되 기독교 상담에서 성경신학적인 원리를 무시하지 않는다. 그러나 성경신학적인 면보다 는 심리학에 대해서 좀더 선호하는 경향이 있으나, 개방유형보다는 보수적이 다. 셋째, 분리유형이다. 이는 기독교상담에서 신학의 영역과 심리학의 영역을 분리하고, 이 두 가지 측면을 동등하게 여기는 입장이다. 이러한 입장은 신학 과 심리학의 공통영역을 어떻게 해결해야 할 것인가에 대한 문제에 대해서 모 호하다. 넷째, 여과유형이다. 이는 성경신학적인 입장에서 심리학을 검증하여, 활용 가능한 심리학적 결과만을 기독교상담에서 활용한다. 이러한 입장은 대부 분의 복음주의적 견해로써, 다양한 일반심리학을 어떻게 검증할 것인가의 문제 가 과제로 남는다. 다섯째, 폐쇄유형이다. 이는 성경만으로 내담자의 모든 문제를 충분히 해결할 수 있다고 보기 때문에 굳이 심리학의 도움을 필요로 하지 않는다. 그렇기 때문에 심리학에 대해서 닫힌 자세를 취하는데, 일반은총으로써의 심리학을 거부하는 약점이 있다. 이상의 내용을 종합해 볼 때 기독교상담자의 심리학 개방성은 상담자의 신 학적 성향과 상호연관성이 있다. 즉 기독교상담자가 신학적으로 진보적일수록 심리학에 대해서 개방적이며, 보수적일수록 심리학에 대해서 폐쇄적인 견해를 보인다. 결론적으로 복음주의 입장의 기독교상담은 심리학을 신학적인 검증을 거쳐서 활용해야하며, 무조건적으로 거부해서는 안 된다고 본다. 복음주의적 기독교상담자는 발견된 진리로써의 심리학을 잘 활용할 뿐만 아니라, 신학과 심리학의 효율적인 통합을 위해서 지속적인 연구활동을 해야 할 것이다. This researcher is to clarify that Christian counseling varies according to counselor`s theological & psychological background. This researcher presumed that openness of psychology is a major factor that represents the tendency of Christian Counseling. Results from this research are as follows: Counselor`s psychological openness is one of the important factors which decides Christian Counseling tendency. Tendency of Christian Counseling in accordance with openness of psychology of Christian Counsellor was classified into 5 types. First, opened type. Christian Counsellor makes best use of reference materials for psychology in counseling, and adopts very open posture to psychology. And they are unconcerned with using the Bible & the theological resources. Second, accepted type. This is a standpoint not to lose an identity of Christian Counseling, whilst admitting psychology. But, They take a little more conservative posture than opened type. Third, separated type. They hold a position to separate the area of expertise, whilst they approve theology and the authority of psychology on equal term. Fourth, filtered type. They use the topics that would not turn out to be the problem connected with Bible after having filtered psychology by means of theology. Evangelical Counselors take this type. Fifth, closed type. They adopt a closed posture toward psychology. They don`t need psychological assistance any more, because they believe that only the Bible can solves counselee`s problem enough. Taken above research results together, Christian Counsellors should know their own tendency toward theology, and openness of psychology. In Conclusion, The evangelical view of Christian counseling is to use the psychological resources filtered theologically, not reject it unconditionally. Also, when conducting counseling having established counseling skills based on such a type they will be able to provide for efficient helps to clients.

비행청소년에 대한 REBT 기반의 경찰 선도프로그램 개발

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.
