Objectives: The purpose of this study is to provide basic information on Korean medical research and treatment through analysis of breast cancer patients, who visited ${\bigcirc}{\bigcirc}$ university Korean medicine hospital. Methods: To analyze characteristics of breast cancer patients who visited korean medicine hospital, we searched medical records from January 1, 2016 to May 13, 2019, and 86 breast cancer patients were analyzed. Results: 1. The general characteristics of the subjects are as follows. The average age was $47.65{\pm}9.62years$ and 40's was the most (46.51%). The average height was $159.78{\pm}4.91cm$ and the average weight was $57.29{\pm}9.34kg$. The average body mass index (BMI) of the patients was $22.40{\pm}3.50kg/m^2$. 2. The stage distribution record indicated stage０ (9.72%), stageI (31.94%), stageII (34.72%), stageIII (20.83%) and stageIV (2.78%). 14 patients with unknown stage were excluded. 3. Before coming to the korean medicine hospital, of the 86 patients, 72 (83.72%) patients received surgical therapy, 55 (63.95%) patients received chemotherapy and 44 (51.16%) patients received radiotherapy. 11 (12.79%) patients chose oriental medicine as their primary treatment option. 4. The mean duration from diagnosis to hospital visit was $13.87{\pm}15.53months$. Among the total 86 patients, 46 (53.49%) patients visited for symptom relief during the follow-up period. 5. The most common symptom was general weakness in 29 (33.72%) patients, followed by hot flash, myalgia, insomnia, digestion disorder, numbness, edema, arthralgia, operation site pain, cold sensation and mastalgia. 6. Among 86 patients, 55 (63.95%) patients received acupuncture and moxibustion together. The most prescribed herbal medicine to subjects was Sibjeondaebo-tang-gamibang and Cheonhye-dan (25%). Conclusions: These results could be helpful to provide basic data on the Korean medical approach of breast cancer patients.

Perioperative pain relief is essential in veterinary practice. However, the cat is one of the most poorly understood species regarding pain control management. Ovariohysterectomy(OHE) produces considerable postoperative pain in cats. Practitioners are often reluctant to administer analgesics due to lack of familiarity with available drugs, concern about side effects, or frustration with the need for record keeping of controlled substances. The purpose of this study was to determine if intraperitoneal administration of bupivacaine can provide relief of pain following OHE in cats. Twelve healthy female cats were randomly divided into two groups. OHE was performed under general inhalation anesthesia. Just prior to complete closure of the linea alba, 6 cats in SAL group received 0.88 ml/kg 0.9% saline, 6 cats in BUP group received 4.4 mg/kg 0.75% bupivacaine diluted to an equivalent volume with saline in the intraperitoneal space. Cats were scored at 0, 1, 2, 4, 8, 12 and 24 hours post-extubation by one observer. Cats were evaluated using a visual analogue scale(VAS) and composite pain scale(CPS) that included physiologic variables. There were no significant differences in body weight, anesthesia time, surgery time, and incision length between the two groups. Cats in the BUP group had significantly(p<0.05) lower VAS-pain scores than cats in the SAL group at 4, 8, 12 hours after surgery. Cats in the BUP group had significantly lower CPS scores than cats in the SAL group at 8, 12 hours after surgery. No adverse side effects were observed. These results support that the intraperitoneal administration of bupivacaine following OHE can be used for the prevention of postoperative pain and pain-induced behavioral changes in cats.

The objectives of this study were to compare visual observation and an electronic grazing time method and to evaluate the effects of nutritional plans on intake, grazing behavior and horizontal and vertical locomotion of young bulls in a tropical pasture. Thirty-nine Nellore young bulls with an average body weight of $345{\pm}9.3$ kg kept in pasture were used. The experimental treatments consisted of: restricted: animals kept in a plot with a low mass of forage receiving mineral mixture only; control: animals receiving mineral mixture only; HPHC: a high protein and high carbohydrate supplement; HPLC: a high protein and low carbohydrate supplement; LPHC: a low protein and high carbohydrate supplement; LPLC: a low protein and low carbohydrate supplement. GPS collars equipped with activity sensors were used. Information about head position, latitude, longitude and altitude were recorded. Daytime grazing behavioral patterns monitored by a continuous focal animal recording method was compared to behavior estimated by the activity sensor. Feed intake was estimated by a marker method. The Restricted group presented lower (p<0.05) intake of dry matter and TDN. However, difference in dry matter intake was not found (p>0.05) between non-supplemented and supplemented animals. Difference was not found (p>0.05) in daytime grazing time obtained by visual observation or the activity sensor method. The restricted group showed longer (p<0.05) grazing time (9.58 h/d) than other groups, but difference was not found (p>0.05) in the grazing time between Control (8.35 h/d) and supplemented animals (8.03 h/d). The Restricted group presented lower (p<0.05) horizontal locomotion distance (2,168 m/d) in comparison to other groups (2,580.6 m/d). It can be concluded that the use of activity sensor methods can be recommended due to their being similar to visual observation and able to record 24-h/d. While supplements with high carbohydrates reduce pasture intake, they do not change grazing behavior. Moderate supplementation (until 50% of protein requirement and 30% of energy requirement) of beef cattle on tropical pasture has no effect on daily locomotion.

Common dental procedures(dental extraction & minor operation) are potentially stress-inducing in many patients, especially medically compromised patients. The body's response to dental stress involves the cardiovascular system(an increase in cardiovascular workload), the respiratory organ and the endocrine system(change in metabolism). To minimize the stress to the medical risk patient, the stress reduction protocol was established. The obtained contents were as follows: (1) Recognize the patient's degree of medical risk (2) Complete medical consultation before dental therapy (3) Schedule the patient's appointment in the morning (4) Monitor and record preoperative and postoperative vital signs (5) Use psychosedation during therapy (6) Use adequate pain control during therapy (7) Short length of appointment : do not exceed the patient's limits of tolerance (8) Follow up with postoperative pain/anxiety control (9) Telephone the higher medical risk patient later on the same day that treatment was given Though the stress reduction protocol above was applied to the dental extraction in medically compromised patients with the advanced infected teeth, the final responsibility for the complications(syncope, bleeding & infection, etc.) in a patient rests with the dentist who ultimately treats him. For the prevention of postextraction complications & poor prognosis, the authors treated the advanced infected teeth with the pulp extirpation, opening drainage through the canal and complete occlusal reduction. The final extraction and wound closure were then done after $1{\sim}2$ weeks. The final prognosis was comfortable without common complications.

The purpose of this study was to investigate the analgesic effect of eugenol, capsaicin and demethoxy-NE. Young adult cats, weighing 2.0 to 3.0kg, were used. Each animal was anesthetized (${\alpha}$-chloralose 60mg per kg body weight) and divided into four groups; control, eugenol, capsaicin and demethoxy-NE group. The anterior digastric muscles were exposed and a pair of electrodes was inserted to record the electromyograms. To expose the pulp, each canine teeth was prepared with a low speed bur under cooling and used for recording anterior digastric muscular EMGs evoked by noxious stimulation of dental pulp. To observe effects on jaw opening reflex, inferior alveolar nerve of both sides were exposed for drug application and wire electrodes were inserted in anterior digstric muscle for recording the EMGs. To observe effects on action potential, saphenous nerves of both sides were exposed and three tissue pools were made from surrounding tissue. The most distal pool was used for applying stimulation, the most proximal one for recording of action potential, and the other one for drug application. One side of inferior alveolar nerve and saphenous nerve were used for eugenol, capsaicin, or demethoxy-NE application, the other side of nerve for control experiments(only vehicle application). Anterior digastric muscular EMGs evoked by noxious stimulation of dental pulp were recorded before drug application, immediate after drug application, at 60 and 120 minutes, and 5 days after drug application. Action potentials were recorded before drug application, immediate after 30 minutes drug application, at 30, 60 and 120 minutes after drug had been washed out. The results were as follows; 1. Eugenol had a continuous blocking effect on the anterior digastric muscular EMGs evoked by noxious pulp stimulation and after 5 days, showed completely blocking effect. 2. After 5 days, demethoxy-NE applied to dental pulp had a considerable blocking effect on the jaw opening retlex evoked by noxious stimulation but capsaicin had no significant effect. 3. After 5 days, eugenol group showed the strongest blocking effect among the all experimental groups on the jaw opening reflex evoked by noxious stimulation of dental pulp and capsaicin group showed the weakest blocking effect. 4. Eugenol had a completely blocking effect on the action potential conductivity of peripheral nerve. Capsaicin and demethoxy-NE had the blocking effect on the action potential conductivity of ${\alpha}$-and C-nerve fibers. 5. Capsaicin, demethoxy-NE and eugenol applied to inferior alveolar nerve surppressed the jaw opening reflex evoked by noxious stimulation of dental pulp.

본 연구는 일제강점기 초기에 한반도 내 명승지를 소개할 목적으로 발간된 나루시마 사기무라[成島鷺村]의 "조선명승시선(朝鮮名勝詩選)"에 수록된 명소들의 유형과 특징을 살펴보고자 하였다. 책을 집필한 의도와 과정을 살피기 위해 서문(序文)과 예언(例言)의 내용을 해석하고, 본문에서 소개하는 약 1700개소의 명승지의 유형, 분포, 특징을 분석하였다. 그 결과 인문경관이 자연경관의 2배 이상 소개되고 있으며, 가장 많이 나타나는 경관유형으로는 불교유적, 누 정, 명산 순으로 나타났다. 그 외 "조선명승시선"은 우리나라선인이 작성한 시문(詩文)의 내용을 활용하여 전래 명승지로써의 개념을 확장하고자한 의도를 파악할 수 있었으며, 일제강점기라는 전환기적 상황을 배경으로 근대 성격을 갖는 근대공원, 근대기념물, 해수욕장, 기차역 등이 사람들에게 새로운 명소로 소개되는 시기임을 확인할 수 있었다. 그러나 연구범위 선정에 있어 명승지의 인식이 변모하는 일제강점기 전과 후 사정을 전체적으로 다루지 못한 한계를 지니고 있으며, 이 시기에 한반도 내 명승이 소개되는 여타 문헌에 대한 비교 분석의 연구 등은 추후 과제로 남겨두기로 한다.

경주 불국사 삼층석탑의 손상 유형은 역사적, 예술적 가치 저하뿐만 아니라 암석 풍화도 가속화 시킬 수 있으므로 보존을 위한 적절한 해결책이 필요하다. 석탑 보존은 선조들이 남긴 원형을 유지하여 후대에 전해주는 데 그 목적을 둔다. 이 과정에서는 손상 상태에 관한 기록을 포함하며 향후 확인 가능하도록 해야 한다. 특히 석탑 손상도 평가는 보존연구와 교육 자료로 활용할 수 있으며 보존처리 기초 자료로 이용하고 예방적 자료를 구축할 수 있다. 이 석탑의 정량적 손상도 평가 결과, 전체 면적 대비 생물 피도 159 %, 화학적 원인 114 %, 물리적 원인 16 % 점유율을 보인다. 또한 서측 방향에서는 일조량과 암석의 팽창수축 영향으로 손상 범위가 95 % 나타났다. 기단부와 탑신부에서는 다른 부재대비 높은 손상률과 복합적 손상 패턴이 관찰된다. 반면에 상륜부는 1970년대 신석재로 복원하여 원 부재 대비 야외노출 시간이 짧기 때문에 보존 상태가 양호한 것으로 판단된다. 이 연구를 바탕으로 보존과정에서는 세척처리를 통해 생물 종의 오염 정도를 저감시킬 수 있으며, 물리적 파손 부재는 접합처리로 손상을 최소화할 수 있다. 하지만 석탑은 향후 재 손상 가능성이 있으므로 지속적인 안전점검 모니터링과 예방적 보존 관리가 필요하다.

The purpose of this study is to analyze the teaching behaviors and visual attention according to teacher's career in Elementary Science Inquire-based Class. Participants were four elementary school teachers in Seoul. They were all in grade 5 and taught science. According to the experience of elementary science education, two novice teachers and two expert teachers were identified. Participants taught Respiration in the 'Structure and Function of our Body' in the elementary science fifth grade. The mobile eye tracker used in this study is SMI's ETG 2w, which is a binocular tracking system. In addition, a video camera was installed behind the classroom to record the entire class. We recorded all the contents of the recorded video and analyzed the results. In this study, the actual practice time, participant's visual attention, and decentralized attention ability were analyzed by class phase. The results of the study are as follows. First, there was a difference between planned class time and actual practice time. The novice teachers were having difficulty in reconstructing the contents of education, and the expert teachers were reconstructing the curriculum and interacting with the students with high understanding and application of the curriculum. There were many differences between the novice teachers and the expert teachers in the tour guidance to confirm student activities. Second, if we look at the visual attention on the area related to teaching and learning by class phase, the novice teacher concentrates all the steps in a specific area, expert teachers showed an equal visual attention to meaningful areas of teaching and learning activities. Third, there was a statistically significant difference in activities 1-1, 1-2, 2-1, and 2-2 when the participants' decentralized attention ability. Expert teachers frequently checked students' understanding and interests. There was a lot of interaction with students. It is also shown through the decentralized attention ability that the novice teachers concentrate on a specific area, and the expert teachers have a high degree of decentralized attention ability and visual attention evenly.
