A 21-year-old woman ingested 1,250 mg of diphenhydramine in a single overdose. Diphenhydramine, a rare ingredient in over-the-counter medication, is used to treat insomnia in Korea. Toxicity is usually limited to anticholinergic symptoms. The standard approach to therapy for the treatment of diphenhydramine overdose is supportive care, including physostigmines and sodium bicarbonates. Here, we review the literature and for the first time report a case of acute diphenhydramine overdosage in Korea, complicated with seizures.

$0.97Bi_{0.5+x}(Na_{0.78}K_{0.22})_{0.5-3x}TiO_3-0.03LaFeO_3$ lead-free piezoelectric ceramics were fabricated by a solid state reaction method. $LaFeO_3$ additives were added to $Bi_{0.5}(Na_{0.78}K_{0.22})_{0.5}TiO_3$ for volatile compensation of bismuth and sodium ions in the sintering process. To create A-site vacancies, the mole ratio and charge valence of A-site ions ($Bi^{3+}$, $Na^+$ and $K^+$) were controlled. The improved piezoelectric properties were observed by addition of $LaFeO_3$ and control of A-site vacancies. In particular, a $d_{33}^*(S_{max}/E_{max})$ value of 614pm/V and an electric field induced strain of 0.33% was observed in $0.97Bi_{0.505}(Na_{0.78}K_{0.22})_{0.485}TiO_3-0.03LaFeO_3$ ceramic.

Objectives The study aimed to examine satisfaction of elementary school students parents' on the program by school doctor of Korean medicine. Methods The program by school doctor of Korean medicine has been conducted in 22 schools in Seoul since June 2017. The program includes Korean medicine health care lecture for the students, the teachers, and the parents, the diet management advice, smoking/drinking cessation, and sex education. The program was varied by schools. This study investigated the parents' satisfaction of the program by school doctor of Korean medicine by a survey. Results A total of 92 elementary school parents participated in the survey, 92.4% of the respondents answered that the school doctor program showed positive effects on students' health. Most of them replied positive regarding the health education about smoking cessation (82.5%). Also, the respondents were satisfied about overall health education from the program (89.1%), and improvements of the students' learning ability through regular health checkups (59.8%). Conclusions Parents who were participated in the program by school doctor of Korean medicine positively evaluated about the program. They also shared their expectations to the role of the school doctor of Korean medicine in improving student's immune system and health counseling for the students and the school faculty.

산란강도의 변동에 따른 통계적 특성은 능동소나의 성능에 영향을 미칠 뿐만 아니라, 주요 산란과정을 이해하는 측면에서 매우 중요하다. 본 논문에서는 천해에서 측정한 해저면 후방산란 신호의 통계적 특성 분석에 대한 내용을 기술하였다. 천천히 움직이는 30kHz의 실험용 소나로 해저면에 대한 자료를 수집하였다. 신호의 진폭변화에 대한 시${\cdot}$공간 상관함수를 계산하였다. 또한, 넓은 빔과 좁은 빔 신호의 포락선에대한 분포함수와 오경보 확률을 계산하고, 이론 모델과 비교를 시도하였다. 분석 결과에서 이동음원에 의한 해저면 후방산란 변동의 통계적 특성은 고정된 음원의 경우와 다른 특징을 나타냈다. Fluctuation statistics of scattering strength are not only important because they impact the performance of active sonar systems, but also because they may provide insight into the major scattering process. In this article, analysis of the statistical characteristics of bottom backscattering, measured in shallow water, are presented. The slowly moving experimental sonar was operated at 30kHz to gather data over the bottom. Spatial and temporal correlation functions of the signal amplitudes were measured. The distribution function and probability of false alarm function of the detected envelope of widebeam and narrowbeam signals were measured. An attempt was made to compare the results with existing theoretical models. The result suggests that the statistical characteristics of bottom backscattering fluctuation of moving source is differ from that of fixed source.

Objectives : The purpose of this study was to examine the effectiveness and satisfaction of visiting Korean Medicine doctor program. Method : The senior center visiting Korean Medicine doctor program was conducted in ten senior centers in Seongnam city from April 2016 to December 2016. Korean Medicine doctors were assigned senior center one by one. The program consisted of health lectures and health counseling. The health lectures embraces stroke, musculoskeletal disease, dementia, depression and self care for the elderly Results : A total of 194 elderly persons participated the program. The self-health awareness level were changed from $50.86{\pm}25.31$ to $57.17{\pm}24.62$ (p-value=0.003). The physical pain level was decreased from $5.33{\pm}2.99$ to $5.04{\pm}2.86$. The quality of life were changed from $0.791{\pm}0.155$ to $0.792{\pm}0.144$ (p-value=0.923). Overall satisfaction of visiting Korean Medicine doctor program was $9.36{\pm}2.11$. The need for sustainability for visiting Korean Medicine doctor program was $9.76{\pm}0.60$. Conclusions : The study demonstrated that visiting Korean Medicine doctor program had a positive effect on the health awareness level. The overall satisfaction and further need were high. Further program for senior center will be needed.

To investigate excess $Na^+$ effect, $Bi_{0.5}(Na_{0.78+x}K_{0.22})_{0.5}TiO_3$ ($0{\leq}x{\leq}0.05$) (BNKT) ceramics were prepared by using a conventional solid-state reaction method. The structure and ferroelectric properties of BNKT ceramics were characterized by XRD (X-ray diffraction) and polarization dependence by external electric field. Also, the temperature dependence of dielectric constant and loss were studied. From these results, it was found that appropriate excess $Na^+$ into BNKT ceramics compensate the volatility and induce dense ceramics. The enhanced piezoelectric coefficient (158 pC/N) and depolarization temperature ($202^{\circ}C$) were obtained for the x=0.01 composition.
