종합편성채널은 수년간 시사 대담 프로그램을 통해 정치적 영향력을 키워 갔지만 정치적으로 편향된 미디어라는 비판을 받고 있다. 본 연구에서는 2017년 7월부터 12월까지 6개월 동안 시사 대담 프로그램에 출연한 패널들의 특성과 함께 패널 발언과 정당 입장간의 상관관계를 분석하였다. 연구결과, 방송 프로그램에서 출연패널의 직군은 정치와 관련이 없는 중립적 직군으로 소개되었으나 이들의 정파성을 고려하여 재분류하면 정당인의 비중이 높아졌다. 또한 패널 발언의 정파성을 살펴본 결과, 대부분의 패널은 여당 혹은 야당의 입장을 견지하고 있었으며, 정당과 연관성이 많을수록 패널의 정파적 발언이 강해지는 것으로 나타났다. 향후 출연패널의 정파성이 명확하게 소개되어야 하며, 일관된 기준으로 장르를 구분하여 심의의 일관성을 확보할 필요가 있다. 또한 프로그램 제작진의 자율규제가 더욱 적극적으로 이루어져야 할 것이다.

본 논문에서는 중국고전문학의 가치를 가장 잘 이끌어 낼 수 있다고 판단되는 '수용적 감상'의 특징과 요건에 관하여 고찰해 보았다. 수용적 감상은 표현 그대로 감상자가 작품을 자신에 맞게 수용하는 감상법이다. 즉 감상자가 작품을 자기화하여 자기만의 감동을 이끌어 내는 감상이라 할 수 있다. 이러한 수용적 감상은 그 특징이 크게 두 가지로 나타나는데, 하나는 한 작품에서 느낄 수 있는 감동이 감상자의 상황이나 인격에 따라 다양하게 달라질 수 있는 것이고, 또 한 가지는 감상자에 의해 작품의 가치가 새롭게 재발견되는 것이다. 천편일률적이지 않은 그러한 다양성이야말로 문학작품의 진정한 의의이고, 훌륭한 문학작품이 '고전'으로 남아있을 수 있는 비결이라 할 수 있다. 감상자가 그러한 수용적 감상을 보다 이상적으로 하기 위해서는 몇 가지 요건을 갖추고 있어야 한다. 작품에 반영된 작가의 가치관이나 작품 제작 당시의 배경 등을 이해하는 것, 그리고 다양한 경험으로 인한 탁월한 안목, 전관적(全觀的)이고 중립적인 사고 등은 감상의 중요한 전제조건이 된다. 이처럼 중국 고전문학의 '수용적 감상'에 대하여 살펴본 작업은, 감상자들이 중국 고전문학 작품에 내재된 무한한 가치와 다양성을 깨닫고 음미하는데 일조할 수 있을 것으로 사료된다.

This study characterize, classify and evaluates the function of topography on spatial variability of some selected soil properties to assist in designing land management that support uniform agricultural production. The study site, an agricultural land, was part of the derived savanna zone in southwest Nigeria. Four soil profile pits each were established along two delineated toposequence and described following the FAO/UNESCO guidelines. Samples were collected from the identified genetic horizons. Properties of four soil series developed on different positions of the two delineated Toposequence viz upper, middle, lower slopes and valley bottom positions respectively were studied. The soil samples were analysed for selected physical and chemical properties and data generated were subjected to descriptive and inferential statistics. The results showed that soil colour, depth and texture varied in response to changes in slope position and drainage condition. The sand content ranged from 61 to 90% while the bulk density ranged between 1.06 g cm^-3 to 1.68 g cm^-3. The soils were neutral to very strongly acid with low total exchangeable bases. Available phosphorus value were low while the extractable micronutrient concentration varied from low to medium. Soils of Asejire and Iwo series mapped in the study area were classified as Typic isohyperthermic paleustult, Apomu series as Plinthic isohyperthermic paleustult and Jago series as Aquic psamment (USDA Soil Taxonomy). These soils were correlated as Lixisol, Plinthic Lixisol and Fluvisol (World Reference Based), respectively. Major agronomic constraints of the soils associations mapped in the study area were nutrient availability, nutrient retention, slope, drainage, texture, high bulk density and shallow depth. The study concluded that the soils were not homogenous, shows moderate spatial variation across the slope, had varying potentials for sustainable agricultural practices, and thus, the agronomic constraints should be carefully addressed and managed for precision agriculture.

The aim of this systematic review was to collect evidence on the following 10 technical aspects of glenoid baseplate fixation in reverse total shoulder arthroplasty (rTSA): screw insertion angles; screw orientation; screw quantity; screw length; screw type; baseplate tilt; baseplate position; baseplate version and rotation; baseplate design; and anatomical safe zones. Five literature libraries were searched for eligible clinical, cadaver, biomechanical, virtual planning, and finite element analysis studies. Studies including patients >16 years old in which at least one of the ten abovementioned technical aspects was assessed were suitable for analysis. We excluded studies of patients with: glenoid bone loss; bony increased offset-reversed shoulder arthroplasty; rTSA with bone grafts; and augmented baseplates. Quality assessment was performed for each included study. Sixty-two studies were included, of which 41 were experimental studies (13 cadaver, 10 virtual planning, 11 biomechanical, and 7 finite element studies) and 21 were clinical studies (12 retrospective cohorts and 9 case-control studies). Overall, the quality of included studies was moderate or high. The majority of studies agreed upon the use of a divergent screw fixation pattern, fixation with four screws (to reduce micromotions), and inferior positioning in neutral or anteversion. A general consensus was not reached on the other technical aspects. Most surgical aspects of baseplate fixation can be decided without affecting fixation strength. There is not a single strategy that provides the best outcome. Therefore, guidelines should cover multiple surgical options that can achieve adequate baseplate fixation.

In human, ultrasonography is used to measure the pennation angle in various muscles to identify muscle functions such as force production, and to study alterations of the pennation angle during muscle contraction, hypertrophy, and atrophy. However, assessments of the pennation angle have not yet been conducted in dogs. This study aims to assess the normal pennation angle of the tibialis cranialis muscle in dogs using ultrasound and to detect changes in this angle in dogs with muscular atrophy. Sixty-eight healthy dogs were examined to establish normal values, while 12 ataxic and 12 lame dogs with suspected hindlimb muscle atrophy were also included. The pennation angle was measured using ultrasound at the midpoint between the proximal end of the tibia and the malleolus, measuring the angle between the muscle bundle and the deep aponeurosis. To confirm the significance between the 5 breeds and to identify a difference between normal and atrophied muscles, statistical analysis was conducted. The study found no significant difference in pennation angle between breeds, with mean values (± standard deviation) of 4.97° (± 1.88) in neutral, 7.25° (± 2.68) in flexion, and 3.31° (± 1.33) in extension positions. Decrease of the pennation angle was identified in muscle atrophy and the flexion position was determined to be the most appropriate for pennation angle measurement of tibialis cranialis muscle. We recommend considering the pennation angle as a valuable indicator of muscle health in dogs, as it demonstrates significant potential for diagnosing and monitoring muscular conditions.

Objective: The aim of this study was to measure the muscle architectural parameters of abdominal muscles in healthy individuals by rehabilitative ultrasound imaging (RUSI) and to investigate their changes after bridging exercise in various environments. Design: Cross-sectional study. Methods: The study included 40 healthy participants (19 men, 21 women). Subjects were randomly allocated to a stable surface group (SG, n=20) or an unstable surface group (UG, n=20). The participants assumed three positions in rest, bridging exercise with knee flexion $60^{\circ}$, and bridging exercise with knee flexion $90^{\circ}$ for the measurement of abdominal muscle thickness by RUSI. For the resting position, the participants held the head neutral in a hook-lying position and the dominant side was measured. For contraction, the participants performed the bridging exercise with the knee joint in $60^{\circ}$ and $90^{\circ}$ of flexion for 10 seconds each. Results: For transversus abdominis, external oblique muscle thickness, within the stable surface group and the unstable surface group, no significant contraction difference was observed in both the $60^{\circ}$ and $90^{\circ}$ bridge exercise conditions. Contraction difference of internal oblique muscle was significantly larger at $90^{\circ}$ than at $60^{\circ}$ within the SG (p<0.05). But within the UG, no significant contraction difference was shown. There was no significant contraction difference between the surface group and the unstable SG at $60^{\circ}$ condition and at $90^{\circ}$ condition in all measured muscles. Conclusions: The contraction difference is different for each muscle during bridge exercise with knee flexion $60^{\circ}$ and bridging exercise with knee flexion $90^{\circ}$. Muscle contraction difference is generally large when exercised on an unstable surface than a stable surface, but these are not statistically significant when bridging exercise is performed using dynamic air cushion for unstable surface.

Occlusal disease is comparable to periodontitis in that it is generally not reversible. Occlusal disease, however, like periodontitis, often maintainable. It does itself to treatment and when restorative dentistry is utilized it becomes, in that sense, reversible. Moreover, a systematized and integrated approach will lead to a prognosis that is favorable and predictable. This approach facilitates development of optimum oral function, comfort, and esthetics, resulting in a satisfied patient. Such a systematized approach consists of four logical phase : (1) patient evaluation, (2) comprehensive analysis and treatment planning, (3) integrated and systematic reconstruction, and (4) postoperative maintenance. An integrated treatment plan is first developed on one set of diagnostic casts, properly mounted on a semiadjustable articulator using jaw relationship records. This is accomplished by using wax to make reconstructive modifications to the casts. These modified casts become the blueprint for planned occlusal changes and the fabrication of provisional restorations. The treatment goals are : (1) comfortably functioning temporomandibular joints and stomatognathic musculature, (2) adherence to the basic principle of occlusion advocated by Schuyler, (3) anterior guidance that is in harmony with the envelope of function, (4) restorations that will not violate the patient's neutral zone. This report shows the treatment procedures for a patient whose mandibular position has been altered due to posterior bite collapse. Migration of the maxillary anterior teeth had occurred, and the posterior occlusal contacts showed pathologic interference. Precise diagnosis using mounted casts was executed and prosthodontic reconstruction by the aid of an unconventional orthodontic correction on maxillary flaring was planned. An unconventional orthodontic correction can be accomplished by using preexisting natural teeth, which can be modified for use in active tooth movement or splinted together for orthodontic anchorage. This technique has an advantage over conventional fixed appliance orthodontic therapy because it can accomplish tooth movement concurrently with restorative and periodontal therapy. On occasion, minor tooth movement can be necessary to achieve the optimum occlusal scheme, crown form, and tooth position for the forces of occlusion to be displaced down the long axis of the periodontally compromised teeth. Once the occlusion, periodontal health, and crown contours for the provisional splinted restoration are acceptable, the final splinted restoration can be similarly fabricated, and it becomes an excellent orthodontic retainer.

Objectives This study is a preliminary study for safe and accurate cervical Hyeopcheok acupuncture by comparing the depth of cervical Hyeopcheok acupoint with cervical spine rotation. Methods Researchers took ultrasonographic images of cervical Hyeopcheok acupoint during full rotation of cervical spine, 45 degree rotation and neutral condition in a prone position. 4 healthy volunteers were recruited. Results No significant difference in needling depth of cervical Hyeopcheok acupoint was observed. However, there were a differences in anatomical structures' shape such as muscles. Conclusions There are no significant difference in needling depth, but anatomical structures' shape were changed. This result mean that if patient rotate cervical spine during acupuncture treatment, it can occur complications. Thus, when acupuncture treatment on cervical Hyeopcheok acupoint, practioner should make subject's cervical spine alignment corrected and be careful not to change posture during the procedure.
