금(金, 1115~1234)이 적극적으로 시행했던 관영수공업 체제와 정책에 주목해 금대 동 경(銅鏡)의 새로운 경향과 특징을 고찰하였다. 금에서는 요, 송계로 구분할 수 있는 전통적 인 양식뿐 아니라 이를 바탕으로 폭포, 나무, 암석, 누각 등을 이용해 회화적인 화면구도로 재구성한 금계 동경들이 제작되었다. 원근법과 상하 구도를 적용한 화면 구성이 거울의 한정 된 공간 속에 적용되었고, 마치 한 폭의 그림처럼 선경의 세계를 표현하거나 관폭도와 같이 떨어지는 폭포를 바라보는 장면들이 동경에 표현되었다. 이러한 특징은 12세기 초부터 금의 수도가 세워졌던 상경성 내지(지금의 黑龍江省 阿城 부근)의 관영 공방을 중심으로 제작되 었다. 금 초기부터 관영수공업 체제에서 동경의 주원료인 구리의 원활한 수급을 위해 동경을 제작하였고 동원(銅院), 경자국(鏡子局), 주경소(鑄鏡所)와 같은 관서를 별도로 조직해 체 계적으로 동경을 제작 및 관리하는 정책을 시행하였다. 한편 중앙관청 중에도 공예품의 제작 과 장인의 운영을 담당했던 소부감과 관련이 있고, 그중에서도 금속공예품의 도안을 담당했 던 도화서 소속의 장인과도 관련이 있을 것으로 파악되었다. 금 정부는 실력 있는 외부 장인 들을 정책적으로 상경성에 집중시켰다. 여진의 토착문화와 기타 여러 민족의 외래문화가 상 경성 내지를 중심으로 흡수 및 통합되면서 금만의 새로운 동경들이 제작될 수 있었다.

장수풍뎅이(Trypoxylus dichotomus)는 오래 전부터 애완·학습용으로 활용되는 정서곤충으로 곤충산업의 씨 앗이 되는 중요한 곤충이다. 2012년 청원군에서 처음 장수풍뎅이 유충이 일제히 사망한 사례가 있고 2014년부터 비슷한 증상의 사례가 전국적으로 발생했다. 2015년에는 이러한 원인이 장수풍뎅이 누디바이러스(Oryctes rhinoceros nudivirus, OrNV)로 인한 것임이 밝혀졌고 2017년에 raw sequencing data가 NCBI에 공개되었지만 추가 분석은 이루어지지 않았다. 따라서, 우리는 국내 장수풍뎅이에서 분리한 누디바이러스(Trypoxylus dichotomus nudivirus, TdNV-KR)로 명명하고, NCBI로부터 수집한 Malaysia, Solomon Islands, Indonesia, Philippines, Palau strain의 OrNV sequence와 비교 분석하였다. 그 결과, TdNV-KR의 genome size는 126,408bp임을 확인하였고 다른 OrNV strain이 비해 가장 적은 open reading frames(ORF)를 가지고 있었으며, 3개의 ORF가 TdNV genome에서만 부재함을 확인했다. 또한, Nudivirus core genes의 아미노산 염기서열 비교에서는 Single-nucleotide polymorphism 과 indels(insertion/deletion)로 인해 highly conserved 한 OrNV strain의 sequence들에 비해 TdNV의 시퀀스는 많은 변이/차이를 보였다. 우리의 연구는 누디바이러스의 종간 전파에 대한 이해도를 높이고, 바이러스 간의 유연관계 를 확인함으로써 유입 경로를 추정하여 산업곤충의 질병을 효과적으로 예방하는 데 기여할 것이다.

The purpose of this study was to identify the immediate effects of Maitland joint mobilization with kinematic taping in subacromial impingement syndrome patients. The Maitland joint mobilization was applied glenohumeral joint. The mobilization was performed at the end of rage to Grade IV. After that, kinematic tape was attached to shoulder joint (supraspinatis, infraspinatis, and trapezius muscles). The intervention period was four days. The measurement was done five times. The shoulder pain, range of motion (flexion, abduction, and rotation of the shoulder joint), muscle tone and stiffness (upper trapezius and deltoid muscle) were measured. The shoulder pain decreased. The range of motion (ROM) was increased all flexion, abduction, and rotation of the shoulder joint. Muscle tone and stiffness were decreased, especially upper trapezius of those was greatly decreased. The findings of present study suggest that Maitland joint mobilization with kinematic taping is effective in decreasing pain, muscle tone and stiffness, and in increasing shoulder ROM in patients with subacromial impingement syndrome.

The purpose of this study was to investigate the effects of occipital bone stimulation by cervical stabilizing exercise on the muscle tone, stiffness, ROM, and cervical lordosis in patient with forward head posture( FHP). This study was a case study of a single patient with forward head posture. This study used a ABA' design, A and A' were the baseline phases and B was the intervention phase. The intervention was occipital bone stimulation by cervical stabilization exercise. It was administered once daily for 7 days. The therapist kept hands together, and placed the two index fingers under the subject's occipital bone. The subject performed the chin-in exercise with a maximum isometric contraction for 20 sec.The exercise was implemented by performing the movements 10 times as a set and repeating the set three times. The muscle tone was not significantly changed after intervention. However, the stiffness was decreased and lasted the effect lasted without intervention. The cervical flexion angle was increased, but the cervical extension angle was not significantly changed after the intervention. The left and right lateral flexion angles were increased and the effect lasted without any intervention. However, the left and right rotation angles were significantly changed after the intervention. Cervical lordosis increased not from 37° to 41° after the intervention. These results suggest that occipital bone stimulation by cervical stabilizing exercise had a positive effect on cervical stiffness, flexion and lateral flexion ROM, and lordosis in a patient with forward head posture.

The purpose of this study is to identify the level of masseter muscle tension according to the levels of restricted movement and pain in the temporomandibular joint(TMJ), thereby verifying the fact that excessive masseter muscle tension can be a cause for restricted movement and pain in the TMJ. The subjects of this study were 81 men and women in their 20s and 30s, who feel uncomfortable with their masticatory function on the preferred chewing side. The subjects were measured in terms of the range of motion (ROM) and deviation of the TMJ and the degree of pain in the affected region. The ROM and deviation of the TMJ were measured using the Global Posture System(GPS) after instructing each subject to open his/her mouth to the fullest and taking photos of the subject with a digital camera. The tension of the masseter muscle was measured with a Pressure Threshold Meter(PTM). After the measurements, in order to compare the ROM of the TMJ, the subjects were divided into two groups based on the ROM of above 35mm and below 35mm. For the deviation and pain, based on the average of total subjects, the subjects were divided into two groups of above and below average. Thereafter, the levels of masseter muscle tension were compared between each pair of groups. According to the results, when each variable was compared between the respective two groups, in terms of the deviation, the pressure pain threshold(PPT) of the masseter muscle revealed a statistically significant difference(p<.05). However, the ROM and pain showed no statistically significant difference. Consequently, masseter muscle tension may cause restricted movement in the TMJ. In particular, the deviation and tension in the masseter muscle is considered to be a factor that causes deviation in the TMJ.

This study was conducted to develop and evaluate food safety training program for employees in foodservice operations. The developed CD-ROM was consisted of 5 parts: foodbome illness, personal hygiene, food handling in food production steps, HACCP system, and sanitary facilities. It has made slides for all contents, the animation and movie to raise interests and concentrations, and illustrations and pictures to understand. The evaluation checklists were developed 15 questionnaires including understanding(5), information(3), concentration(4), recommendation(2), and the most important factor(1) and measured by Likert 5-point scale. Fifty-four dietitians in Daegu and Gyeongbuk schools, hospitals, and industries foodservice operations responded to the surveys. The results are as follows; The most important part in the CD-ROM was personal hygiene(33.3%). The total mean was 3.95±0.41, 3.91±0.46 on understanding, 3.89±0.50 on information, 3.87±0.55 on concentration and 4.29±0.49 on recommendation. The score was significantly higher in the recommendation part than others. Overall, as the developed CD-ROM has achieved fine score, a study on the effect of education needs to be followed. Moreover, consistent and organized education by developing a variety of sanitation education methods should be conducted.

Research has shown that using multimedia teaching materials such as movie videos and CD-ROMs in foreign language classrooms has been effective. The purpose of the present study is to investigate the effects of using a movie CD-ROM in English classrooms as a way of improving English language skills and enhancing students’ positive perception of learning English. Sixty 10th-grade students in a commercial high school participated in the study which lasted 10 weeks. One group used the movie Big, while the other group used the conventional method of listening to a tape that accompanied a textbook. The data, which were analyzed statistically using the SPSS, showed the following results: 1) Even though the experimental group’s level of interest and confidence increased by using the movie CD-ROM, the increase was not statistically significant. The same can be said for the control group. 2) The experimental group showed a statistically significant improvement in vocabulary building, while the control group did not. 3) Neither group showed significant improvement in terms of listening ability.

A single subject experimental design (alternating treatment design) was used to compare the effects of only ultrasound and ultrasound combined with stretching of the joint capsule on the ROM increase and pain reduction in patients with frozen shoulder. Two subjects were included in each group. In the only ultrasound treatment sessions, ultrasound was applied at the pain point of the shoulder joint in supine position. In the ultrasound combined with stretching treatment sessions, ultrasound was applied at the pain point of the shoulder joint positioned in external rotation and abduction in sitting position. Only ultrasound treatment and ultrasound combined with stretching treatment were alternately performed on each patient. Pain and disability was measured by shoulder pain and disability index (SPADI), and range of motion (ROM) was measured by scratch test. The results of this study showed that ultrasound combined with stretching treatment were more effective than only ultrasound treatment in ROM increase and pain reduction. However, disability score was not significantly different.

A single subject experimental design (alternating treatment design) was used to compare the effects of Mulligan method and electrotherapy on the pain and limitation of range of motion in patients with frozen shoulder. In the Mulligan method sessions, the physiotherapist performed a posterior and caudal glide on the patient while the patient was performing shoulder flexion and abduction. In the electrotherapy sessions, the patient received ultrasound and interference current treatments. Mulligan method and electrotherapy were alternately performed on each patient. Pain was measured by visual analogue scale (VAS) and range of motion (ROM) was measured by modified finger ladder. The results showed that both Mulligan method and electrotherapy were effective in pain reduce and ROM increase, but Mulligan method was superior to electrotherapy in ROM increase while electrotherapy was superior to Mulligan method in pain reduce.
