최근 1인 가족 증가 및 핵가족화로 인해 미니수박에 대한 소비가 증가되고 있다. 따라서 미니수박에 대한 표준재배법을 확립하기 위하여, 재배유형에 따른 재식거리가 미니수박의 생육, 수량성, 과실특성과 라이코펜 및 당함량 등에 미치는 영향을 조사하였다. 정식 30일 및 90일후 생육은 재배유형별로 재식거리가 클수록 생육이 양호하였으며, 수확기의 후기생육은 포복형 재배보다는 아치형이나 ∩자형에서 가장 양호하였다. 주당 착과수는 재배유형별로 유의한 차이는 없었으나, 단위면적당 수량은 밀식재배가 가능한 ∩자형이 아치형과 포복형에 비해 50% 이상 높았으며, 당도가 다소 증가하였다. ‘Minimi’의 과실당 종자수는 대과종인 ‘삼복꿀’과 비슷하였으나, 종자 100립중은 ‘삼복꿀’의 1/3크기로 작았다. 라이코펜 함량은 ‘삼복꿀’보다 ‘Minimi’에서 30% 이상 높았고, 당성분은 유의한 차이가 없었다. 따라서 미니수박의 재배방식은 ∩자형 지주재배가 포복재배나 아치형에 비해 단위면적당 수량과 품질이 높았으며, 재식거리는 120×40cm에서 수광량, 생육, 수량 및 품질 등에서 가장 양호하였다. Recently, the interest and consumption of mini watermelon (Citrullus lunatus Thunb.) are increasing due to nuclear family and one person household. However, there’s no research for mini watermelon. Therefore, the purpose of the study is to develop standard cultivation method of mini watermelon. The test cultivar is ‘Minimi’, which is a small-sized fruit, the rootstock is ‘Bullojangsaeng’, which is a cucurbit line. Grafted plants were transplanted on April 5, 2017, and harvested in early July. Cultivated types were 3 methods, which are ∩-form, arched, and runner type, and plant spacing were 40, 60, and 80 cm, respectively. The rowth and yield in ∩-form was higher than that of the arched and runner types, and the sugar content was higher a bit. The yield per unit area was about 50% higher than ∩-form, which can be plant density cultivation than that of the runner type. The number of seeds per fruit of ‘Minimi’ was similar to that of ‘Sambokggul’, but seed weight was one third lower than that of ‘Sambokggul’. The content of lycopene was 30% higher than that of ‘Sambokggul’ watermelon, and the main sugar content is similar to or slightly less. In conclusion, the ∩-form staking cultivation was superior to the runner type or arched cultivation in terms of fruit setting ratio, yield and quality.

<P>Although primary small intestinal carcinoma (SIC) is morphologically similar to colorectal carcinoma and shares many of the genetic changes of carcinogenesis, little is known about the role of defective mismatch repair (MMR) genes involved in the SIC. The aim of this study is to investigate the role of defective MMR genes and correlation between clinicopathological factors and loss of MMR protein in SIC.</P>

[ $TiO_{2}-ZrO_{2}$ ] powders were successfully synthesized by the sol-gel process using titanium iso-propoxide as a precursor. The amorphous $TiO_{2}$ particles, 70 nm in size, homogenously adhered to the surface of $ZrO_{2}$ the powders. After calcination at $450^{circ}C$, most of the $TiO_{2}$ powders appeared as an anatase type, whereas they changed to a rutile phase at $750^{circ}C$. For comparison of photocatalytic activity, $TiO_{2}-ZrO_{2}$ nano-sized powders calcined at $450^{circ}C,\;600^{circ}C,\;and\;750^{circ}C$ were used. In the $TiO_{2}-20wt\%$ $ZrO_{2}$ powders calcined at $450^{circ}C$, there was excellent removal efficiency of Methyl Orange (MO). For the calcination temperature increased, $TiO_{2}ZrO_{2}$ nano-sized powders increased $ZrO_{2}$ contents showed the good photoactivity for the photooxidation of MO.

Purpose: There have been no studies employing a specific questionnaire relating to patient satisfaction following ambulatory hernioplasty. Via the production of a novel specific questionnaire, attempts were made to determine the factors associated with patient satisfaction following hernioplasty on an ambulatory basis. Methods: Patient satisfaction was evaluated via cross-sectional telephone surveys administered 10.5 (range of 2∼23) months after their operations, consisting of six questions, regarding; anesthetic technique, surgical method, necessity for admission, necessity for follow-up, intraoperative pain, and postoperative pain. Each of the questions was then scored using a 4-point scoring system, with global satisfaction determined via the addition of each score. Factors related to global satisfaction were determined among preoperative, intraoperative and postoperative factors. Results: Telephone questionnaire interviews were conducted on all 131 consecutive patients. Four respondents (3.1%) expressed dissatisfaction with the ambulatory surgery. Twelve (9.2%) had been admitted overnight after the operation. Thirteen (9.9%) required analgesics for over 3 days. No patients required a re-operation, although 20 (15.3%) experienced minor postoperative complications. Significant factors for global dissatisfaction were analgesic requirement for over 3 days and the presence of surgical complication (P value <0.05). Time until return to work and required overnight admission were important factors for patient satisfaction, but these were not significant. Conclusion: Patient satisfaction was associated with postoperative pain and surgical complications. Therefore, a more appropriate method for pain control and prevention of minor surgical complication are suggested might serve to enhance patient satisfaction after hernioplasty on an ambulatory basis.

Most organic fertilizers are manufactured using imported ingredients and organic fertilizer can improve the agricultural productivity through soil fertility improvement and microbial activity increase. Ammonia (NH₃) is mostly emitted from the agricultural sector and the NH₃ emission from fertilizer use is about 7%. Biochar can be produced under oxygen-limited conditions using several biomass and biochar has effects such as carbon sequestration and heavy metal adsorption in the soil. In this study, the organic fertilizers (OF) were classified according to the type of ingredients and the mixing ratio, and the NH₃ emission was evaluated using a dynamic chamber method. OF1 and OF2 are commonly used organic fertilizers in domestic, and OF3 and OF4 are manufactured by mixing biochar. When only organic fertilizers were used, OF1 represented the highest emission (25.12 kg ha<SUP>-1</SUP>), and when both organic and inorganic fertilizers were treated, OF3+NPK expressed the most volatilization (155.41 kg ha<SUP>-1</SUP>). When biochar is added to organic fertilizer, the pH and total nitrogen content of the organic fertilizer decreased and the total carbon content and inorganic contents increased. However, when organic fertilizer contained biochar is treated to the soil, it is thought to be beneficial to growth of crops by increasing the content of phosphate and potassium. This study evaluated the possibility of replacing some of the ingredients of organic fertilizer with biochar and the emitted NH₃. Results showed that it is most advantageous to promote crop growth when producing like OF4 type.
