The experiment was conducted to establish the effects of rootstock weight of chicory expected to become exporting crop, for preventing Korea from importing the foreign chicon and increasing the grower`s profits. The weight of rootstock is based on the 4 treatments such as 100, 150, 200, and 250 g. In the rootstock weight of chicory, the growth was best in the 250 g treatment, but the hardness had no differences among them. Number of outer leaf was 7.4 in the 100 g treatment. The quality was the same as the growth`s condition. Therefore, the optimal condition for the rootstock weight of chicory is 250 g.

Background: Transferring the hypoglossal nerve to the facial nerve using an end-to-end method is very effective for improving facial motor function. However, this technique may result in hemitongue atrophy. The ansa cervicalis, which arises from the cervical plexus, is also used for facial reanimation. We retrospectively reviewed cases where facial reanimation was performed using the ansa cervicalis to overcome the shortcomings of existing techniques of hypoglossal nerve transfer. Methods: The records of 15 patients who underwent hypoglossal nerve transfer were retrospectively reviewed. Three methods were used: facial reanimation with hypoglossal nerve transfer (group 1), facial nerve reanimation using the ansa cervicalis (group 2), and sural nerve interposition grafting between the hypoglossal nerve and facial nerve (group 3). In group 1, the ansa cervicalis was coapted to neurotize the distal stump of the hypoglossal nerve in a subset of patients. Clinical outcomes were evaluated using the House-Brackmann (H-B) grading system and Emotrics software. Results: All patients in group 1 (n= 4) achieved H-B grade IV facial function and showed improvements in the oral commissure angle at rest (preoperative vs. postoperative difference, 6.48°± 0.77°) and while smiling (13.88°± 2.00°). In groups 2 and 3, the oral commissure angle slightly improved at rest (group 2: 0.95°± 0.53°, group 3: 1.35°± 1.02°) and while smiling (group 2: 2.06°± 0.67°, group 3: 1.23°± 0.56°). In group 1, reduced tongue morbidity was found in patients who underwent ansa cervicalis transfer. Conclusion: Facial reanimation with hypoglossal nerve transfer, in combination with hypoglossal nerve neurotization using the ansa cervicalis for complete facial palsy patients, might enable favorable facial reanimation outcomes and reduce tongue morbidity. Facial reanimation using the ansa cervicalis or sural nerve for incomplete facial palsy patients did not lead to remarkable improvements, but it warrants further investigation.
Capsicm annuum에 있어 雌雄兩不稔에 對한 硏究 : 1. 組織學的 機構에 對한 調査 1. Study on histological mechanism
金鎭洙,劉成吾 圓光大學校 園藝學硏究會 1971 園藝學會誌 Vol.- No.4
同一花內에서 雌雄兩不稔을 兼하고 있는 個體의 조직학적 기구에 대한 調査를 한바 다음과 같은 結果를 얻었다. A. 雌性不稔의 原因 1. 영양적 불균형으로 花粉이 형성되지 못하는 경우 2. 花粉은 生成되나 葯이 裂開되지 못하는 경우 但 生成된 花粉중 無能花粉은 15-74%이다. B. 雌不稔性의 原因 1. 영양적 불균형으로 胚襄이 완전히 退化되는 경우. 2. 胚襄은 退化되지 아니하나 八核形成後 核의 配置가 비정상적인 경우. 3. 畸形花柱가 形成되는 경우 ① 畸形花柱는 柱花가 짧고 基部로부터 2-3열 되어있고 ② 柱頭에는 점액이 生成되지 못한다. C. 고추에 있어 雌性不稔의 類型 1. 花粉이 形成되지 못하는 型. 2. 葯이 裂開되지 못하는 型. 等의 二型으로 나눌 수 있다. Investigation into histological mechanism of bisexual sterility in the same flowe shows following data. A. The cause of male sterility 1. Failure of pollen formation due to nutritional unbalance 2. Failure of dehiscence of anther though capable of pollen formation rf (incapabie ones from amonng pollens already formed covers 15-74%) B. The cause of female sterility 1. Degeneration of embryo sac due to natritional unbalauce. 2. Abnormal location of 8 - nucleus though embryo sacremain normal. 3. The occurrence of deformed stigma. 1) This one is short of its stigma in length and is divided into 2-3 sectors from under the base. 2) Mucus is absent at the upper surface of the stigma. C. The mode of sexual stcrility in Capsicum annuum may be classified into forlowing two types. 1. Failure of pollen formation. 2. Failure of dehisceuce of anther.
