Purpose : Prostate volume has been poorly correlated to various parameters used to assess benign prostatic hyperplasia (BPH), including symptom score, peak urine flow and detrusor pressure at peak urine flow. The purpose of this study was 2-fold: 1) to determine if transrectal ultrasound measurement of the transition zone of the prostate served as a better proxy for determining prostate size and correlated better with IPSS, peak urine flow and detrusor pressure and 2) if the parameter transition zone index (the ratio between transition zone volume and prostate volume) was useful in evaluating clinical prostatism. Materials and Methods: We prospectively evaluated 30 men with symptomatic BPH (mean age 65.4 years) according to symptom sore, peak urine flow, pressure/flow study, transrectal ultrasound volume of the entire prostate and the transition zone and calculation of the transition zone index. Results : There was a week correlation between prostate volume and symptom score, peak urine flow and detrusor pressure at peak urine flow: a stronger correlation between volume of transition zone and symptom score (r=0.679 p=0.03), and peak urine flow (r=-0.672 p=0.05) and a significant correlation (p=0.001) between transition zone index and symptom score (r=0.868), and peak urine flow(r=-0.870). Conclusion : Transition zone index is a parameter that correlates siginificantly with parameters of BPH and may serve as a useful proxy for evaluating worsening obstruction. Studies are underway to determine whether transtion zone index can be used prospectively to predict and correlate response with therapies designed to ablate prostatic tissue medically or surgically.

This study was designed to clarify histological changes in the experimental rabbit ureter after unilateral prartial or complete ureteral obstruction. A total of 20 adult white rabbits were divided into 4 subgroups in the partial obstruction followed by 2 weeks, partial obstruction followed by 4 weeks, complete obstruction followed by 2 weeks, complete obstruction followed by 4 weeks. The normal control group consisted of 5 adult white rabbits. The H & E stain. light microscopy were used. Abnormal histological fingings were showed in ipsilateral ureter of all subgroups; dilatation of ureter, epithelial cell atrophy or loss, interstitial fibrosis, interstitial inflammation. These findings were most severe in the complete-obstructed ureter for 4 weeks. There were no significant changes in contralateral ureter of all subgroups. Despite of progressive histological changes in ipsilateral ureter no abnormal findings were showed in contralateral ureter. We suggest that long term experimental investigation for histological changes in ipsilateral ureter and compensatory changes in contralateral ureter should be done.

Objectives : The direct causal relationship between the experience of sexual assault and development of psychiatric disorder remains uncertain. However, studies consistently show that those with history of this horrendous event report a wide range of symptoms, higher level of distress, and various social and psychological problems. This study investigated the prevalence and associated risk factors in a cohort sample of 340 Korean psychiatric patients. Methods : Data from consecutive 340 new patients were gathered at a psychiatric department of a university affiliated hospital. Participants completed Life Events Scale, Symptom Checklist-90-R, State-Trait Anxiety Inventory, Beck Depression Inventory, and Dissociative Experiences Scale. Results : History of sexual assault was reported by 11.5% of respondents (women 18.6% ; men 2.1%). Bivariate analysis revealed that women (p<.001), divorced or widowed and never been married (p<.05), unemployed and students or housewives (p<.05), monthly income more than 2 million Won (p<.05) were associated significantly with experience of sexual assault. All the scores from the scales but Beck Depression Inventory were significantly higher for the sexually assaulted. Multiple logistic regression analysis revealed that women were 12 times more likely to be sexually assaulted (Odds ratio=12.24, 95% CI=3.51 -42.64). Other risk factors included younger age and interacdon of post-traumatic stress disorder (PTSD) and Global Severity Index. Conclusion : This study supported the risk factors of sexual assaults identified in western literature. Clinicians can be alert for any history of sexual assault when younger women with PTSD present higher level of symptomatology.

절화 국화 ‘백마’를 재배하고 있는 관행농가와 스마트팜의 시설현황, 재배환경, 절화생육 및 경영성과를 비교 분석하였 다. 관행농가는 비닐하우스에서 토경으로, 스마트팜은 유리온 실에서 양액재배하고 있었다. 스마트팜은 광량, 온도, 습도, CO2, 풍속, 강우, 양액 pH와 EC 측정을 위한 센서들을 갖추어 자동제어하고 있었으며, 실시간으로 컴퓨터와 휴대전화 어플 리케이션을 이용하여 온실을 관리하고 있었다. 반면에 관행농 가는 환경 측정용 센서와 관비재배용 pH와 EC 센서들이 전혀 없었고, 모든 시스템들을 수동으로 작동하고 있었다. 시설 내의 주간과 야간온도는 관행농가에서 생육 적온보다 낮게 관리되고 있었다. 관행농가의 토양 EC는 3.2dS・m-1로 높게 나타나 절화 생육에 적합하지 않은 것으로 나타났고, 스마트팜은 1.1dS・m-1 로 적절하게 관리하고 있었다. 재배방법에 있어서 토양소독은 관행농가에서는 실시하지 않았으며, 스마트팜에서는 과산화수 소를 이용하여 토양소독을 실시하고 있었다. 그 외에 재배방 법은 큰 차이가 없었으나, 관행농가에서 응애가 많이 발생하 여 피해증상이 나타났다. 절화장, 화폭, 생체중, 엽록소 함량 등과 같은 절화 생육은 관행농가보다 스마트팜에서 더 양호한 것으로 나타났다. 경영성과 측면에서 1,000m2 기준으로 순이 익은 관행농가에서 -419천원이었고, 스마트팜은 4,484천원이 었으며, 생산량과 수취가격이 관행농가보다 스마트팜에서 각 각 22%와 52% 더 높은 것으로 나타났다. 이와 같은 절화의 생육과 경영성과의 차이는 스마트팜의 자동화 설비에 의해 정 밀 생육관리가 가능했기 때문이라고 판단되었다. We analyzed and compared the facility status, cultivation environment, growth of flowers, and management performance of a conventional farm and a smart farm in which Chrysanthemum ‘Baekma’ was grown. The conventional farm consisted of cultivation with soil culture in a plastic film greenhouse, whereas the smart farm consisted of hydroponic cultivation in a glass greenhouse. The smart farm was equipped with sensors for measuring solar radiation, temperature, humidity, CO2, wind speed, rainfall, and pH and electrical conductivity (EC) of the nutrient solution, and was managed in real time using computers and mobile phone applications. In contrast, the conventional farm had neither sensors for environmental measurement nor pH and EC sensors for fertigation, and all systems were operated manually. The day and night temperatures in the plastic film house of the conventional farm were lower than the optimum growth temperature of Chrysanthemum ‘Baekma’. The soil EC of the conventional farm was found to be high (3.2 dS・m-1) indicating that it was not suitable for the growth of cut flowers, whereas the smart farm was properly managed at 1.1 dS・m-1. With respect to the cultivation method, no soil disinfection was performed at the conventional farm, whereas disinfection using hydrogen peroxide was performed at the smart farm. Although there were no other significant differences in cultivation methods, symptoms of damage by mites were seen at the conventional farm. The plant growth, such as length of cut flowers, flower diameter, fresh weight, and chlorophyll content were improved in the smart farm compared with the conventional farm. In terms of management performance (based on an area of 1,000 m2), the net income was -419,000 won for the conventional farm and 4,484,000 won for the smart farm, and the yield and sales price were 22% and 52% higher in smart farm than in the conventional farm, respectively. The results of this study indicate that the differences in the plant growth as well as management performance can be attributed to precise plant growth regulation by the automated facilities at the smart farm.

The objective of this study was to determine the effect of replacing perlite (PL) with pellets processed with poultry feather fiber as an inert material to prepare growing medium. The growth and flowering of Salvia splenden s ‘Vista Red’ grown in individual growing medium Biosangto<SUP>®</SUP>, peat moss (PM), PL, and two pellets (P45-1 and P45-2) were evaluated. Peat moss was mixed with PL, P45-1, or P45-2 at various ratios (1:0 to 1:3 or 3:1 by volume) to investigate the feasibility of replacing PL with pellets. Nutrient composition of the growing medium and leaf tissues was analyzed. The number of florets, inflorescence length, plant height, and fresh weight of plants grown in media containing P45-1 or P45-2 were reduced compared to those grown in individual growing medium PM or PL. As the mixing ratio of P45-1 or P45-2 to PM was higher, the growth of salvia, such as inflorescence length, plant height, number of leaves, and fresh weight was inhibited. Our results indicate that mixing three parts PM with one part of P45-1 (PM/P45-1/3:1) or P45-2 (PM/P45-2/3:1) accelerated flowering and increased the number of florets and leaves compared to other mixing ratios of PM and pellets media. The concentrations of phosphorus (P), calcium (Ca), boron (B), iron (Fe), and copper (Cu) in individual growing medium PL, P45-1, and P45-2 were significantly lower than those in PM. The concentration of N was the highest in leaves of plants grown in P45-1 or P45-2 amended media, and the concentrations of P, Ca, and zinc (Zn) in leaves were lower in individual growing medium P45-1 or P45-2 than in PM and PL. The pH of PM/P45-1/3:1 or PM/P45-2/3:1 media was maintained at optimal level (5.8-5.9) and the concentrations of macro- and micro-elements in the media and leaves were considered to be optimal levels. Therefore, mixing three parts PM with one part P45-1(PM:P45-1/3:1) or P45-2 (PM:P45-2/3:1) is recommended for improved growth and flowering in salvia. This suggests that P45-1 or P45-2 can replace PL as an inert material to prepare growing medium.

Vase Life and Quality of Cut Flower by NaOCl and Sucrose Treatment as Wet Harvesting Solution in Standard Chrysanthemum ‘Baekma’

Yong Seung Roh,In Kyung Kim,Yong Kweon Yoo 한국인간·식물·환경학회 2017 인간식물환경학회지 Vol.20 No.5

This study was carried out to examine the effective wet harvesting solution for development of wet distribution system in standard chrysanthemum (Dendranthema grandiflorum) ‘Baekma’. The cut flowers were treated immediately in floral preservative solutions or dry condition after harvesting, and then the effects on quality of cut flower were compared. Also, we investigated the effects of NaOCl and sucrose on vase life and quality of cut flower. When the cut flowers were treated immediately in tap water, Chrysal OVB, Floralife, Hiflora solutions after harvesting, flower diameter and fresh weight of cut flower increased compared to dry condition treatment. In single treatment of 100 mg・L-1 NaOCl as wet harvesting solution, flower diameter and fresh weight of cut flower increased more than other treatments, and vase life was prolonged to 1.5 days than control. But, flower diameter and fresh weight of cut flower decreased in 0 or 200 mg・L-1 NaOCl. When the cut flowers were treated in combination solution of 100 mg・L-1 NaOCl and 0.1% sucrose, the flower diameter was the largest by 9.8 cm, and fresh weight of cut flower was maintained the highest in holding solution. On the other hand, flower diameter and fresh weight of cut flower were lowest in combination solution of 100 mg・L-1 NaOCl and 2.5% sucrose. There was no difference in vase life between treatments mixed with NaOCl and sucrose. Therefore, it was suggested that treatment mixed with 100 mg・L-1 NaOCl and 0.1% sucrose as wet harvesting solution was the most effective for vase life and quality of cut flower in standard chrysanthemum ‘Baekma’.
