After a longitudinal analysis of the data on the college entrance examination of students enrolled in the Department of Chemistry Education at Gyeongnam from 2014 to 2021, the effect on the academic achievement of general chemistry according to the type of college entrance examination was studied. And the impact on the academic achievement of general chemistry according to the type of admission screening in face-to-face and non-face-to-face teaching-learning was also studied. As a result of analyzing the academic achievement of general chemistry by admission process, students admitted through occasional screening showed relatively high grades of A and B at 88.7%, and the ratio of grades of 1~3 of chemistry I in high school was high. On the other hand, in the case of students admitted through regular admission, the ratio of grades of A and B in general chemistry was very high at 94.3%, and the ratio of grades of 3~4 in chemistry I of the College Scholastic Ability Test was high. As a result of analyzing the academic achievement of general chemistry by class type and admission process, it was found that the grades of chemistry I by face-to-face classes had an effect on the academic achievement of general chemistry in non-face-to-face classes. In both admissions, the academic achievement of general chemistry by face-to-face classes was relatively higher than that of non-face-to-face-to-face classes.

본 연구는 2011학년도 A대학교 입학생 중 일반전형으로 입학하여 현재 재학 중인 학생들을 대상으로 입학전형요소가 학업성취도에 어떠한 영향을 주는지 상호관련성을 분석하였다. 학업성취도와 밀접히 연관되어 있는 전형요인을 찾아 대학의 특성에 맞는 학생 선발 정보를 제공하여 각 대학별 입시안 마련에 도움이 될 것으로 기대된다. 분석결과 성별, 모집시기별로 입학전형요소가 학업성취도에 다른 방식의 영향을 주는 특성을 관찰할 수 있었다. 여학생들이 남학생보다 학업성취도가 더 높고, 수시모집 학생들에 비해 정시모집 학생들의 학업성취도가 높게 나타났다. 성별 분석에서 남학생은 수능성적, 여학생은 학생부성적이 학업성취도에 큰 영향을 미치는 것으로 나타났으며 모집시기별 분석에서는 정시(나)는 학생부성적, 정시(다)는 수능성적이 학업성취도에 큰 영향을 미치는 것으로 나타났다.

To find out the effect of interest on chemical content, interest in chemistry, choice of science elective subjects, teaching-learning characteristics that make it difficult to understand contents, academic achievement in general chemistry according to university admission screening, etc. were surveyed on 51 students enrolled in the department of chemistry education at P college of education. As a result of the survey, it was found that the interest in Chemistry I, Chemistry II, and general chemistry increased significantly to 94.6%, 73.7%, and 66.0%, respectively. 39.3% of the students answered that they had a lot of difficulty in understanding general chemistry. The characteristics of learners who make it difficult to understand the content were found to be 'lack of willingness to learn' such as 'lack of understanding chemical concepts' and 'lack of problem solving', due to the lack of 'basic knowledge'. As a way to solve these difficulties, 'expert help' appeared the most. The grades of general chemistry of students who entered the regular admission were relatively higher than those of occasional recruitment.

The patient was 17 years old female who complained of coldness of right arm and occasional dizziness, since 4 months prior to admission. On physical examination, the right radial, brachial and common carotid arterial pulses were not palpable. Aortography revealed narrowing of innominate and right common carotid arteries, and complete obstruction of right subclavian artery. The right axillary artery was faintly visualized on the delayed film. Axillo-axillar bypass was done using Gore-Tex graft of 8 mm I.D.. By bilateral subclavicular incision, both side axillary arteries was exposed. End to side anastomosis was made between graft and right axillary artery and the graft was brought out to the left side, subcutaneously, over the sternum, and the anastomosis was made between graft and left axillary artery. Postoperatively, both radial pulses were equally palpable. On follow-up visiting, there were no subjective symptoms and blood pressure in both arms was equal.

Medicinal plants and their products are popular in Estonia. There are two approaches to use of herbal products: first, that based on traditions and practical experience and, second, that supported by scientific evidence. It is important to marry these two approaches. One place where traditions and new knowledge could meet is the pharmacy. In this study we evaluated knowledge about the use and safety of herbal products of pharmacy customers in South-Estonia. A convenience sample of pharmacy customers in south Estonia (n = 196) participated in the study. Of the survey participants, 76% were frequent or occasional users of herbal products and considered these products safe (75%) and effective (73%). Herbal products were mostly (91%) consumed for prophylaxis or treatment of minor illnesses. Main information sources about herbal products were pharmacists (75%) and package information leaflets (65%). Mode of action (95%), administration (81%) and indication (77%) were the information details more frequently sought from the pharmacy about herbal products. Of the survey participants, 22% described some problems connected with the use of herbal products. Herbal products are popular in Estonia and pharmacists have an important role in counselling on these products. Despite knowledgeable use of herbal products and infrequent experience of side effects with these products, safety issues should be more stressed in the providing of information details to pharmacy customers.

Honey is produced by bees from nectar collected from nearby flowers. Sometimes, honey produced from the Rhododendron species is contaminated by Grayanotoxin (GTX) in Nepal and other countries. There have been reports of GTX intoxication, also known as 'mad honey disease', from honey produced in countries other than Korea. The importation of wild honey has been prohibited by the Korean Food and Drug Administration since 2005, yet it is still distributed within Korea by the occasional tourist. We report a case of GTX intoxication from contaminated honey which included the symptoms of nausea, vomiting, general weakness, dizziness, blurred vision, hypotension and sinus bradycardia. By means of infusion with normal saline and atropine sulfate, the patient's condition fully recovered within 8 hours of hospital admission, and she was discharged without any complications.

Even in the hands of the expert endoscopists, an occasional instrumental perforation of the esophagus occurs. But instrumental perforation of the esophagus should not be difficult to diagnose if the possibility is borne in mind. Occasionally patient with esophageal perforations show little reaction at first, but usually they develop systemic manifestation if surgical management is delayed. Early surgical drainage of esophageal perforation is very important & effective therapeutic method. The delayed surgical treatment of esophageal perforation would have increased the morbidity & mortality by allowing mediastinitis & empyema thoracis. We have experienced 6 cases of delayed surgical management of instrumental perforation of esophagus from May 1974 to April 1986 in the department of thoracic and cardiovascular surgery, Yonsei University, college of the medicine. The ages ranged from 4 years to 57 years. The underlying esophageal diseases consisted of esophageal stricture in 3 cases, foreign bodies in the esophagus in 2 cases and esophageal ca. in one case. Most clinical manifestations on admission were high fever, chest discomfort, chest pain, dysphagia and subcutaneous emphysema. Most complications due to esophageal rupture were acute mediastinitis with or without empyema thoracis. Failure to diagnose promptly and failure to promptly institute adequate treatment undoubtedly were largely responsible for this patients death. All 6 patients had been taken delayed surgical drainage more than 24 hours following esophageal perforation. One patient had been in the open drainage state for long time and the another patient has been in the tracheostomy with postintubation vocal cord ulceration. The third patient died due to respiratory failure and sepsis due to fulminant mediastinitis & empyema thoracis. Even if the patients with esophageal perforation have been taken delayed surgical management, the patients should be survived with aggressive & effective surgical drainage with intensive post-operative care.
