  • Background: Preoperative 5-fluorouracil (5-FU)-based chemoradiotherapy is a standard treatment for locally advanced colorectal cancer (CRC). However, CRC cells often develop chemoradiation resistance (CRR). Recent studies have shown that long non-coding RNA (lncRNA) plays critical roles in a myriad of biological processes and human diseases, as well as chemotherapy resistance. Since the roles of lncRNAs in 5-FU-based CRR in human CRC cells remain unknown, they were investigated in this study. Materials and Methods: A 5-FU-based concurrent CRR cell model was established using human CRC cell line HCT116. Microarray expression profiling of lncRNAs and mRNAs was undertaken in parental HCT116 and 5-FU-based CRR cell lines. Results: In total, 2,662 differentially expressed lncRNAs and 2,398 mRNAs were identified in 5-FU-based CRR HCT116 cells when compared with those in parental HCT116. Moreover, 6 lncRNAs and 6 mRNAs found to be differentially expressed were validated by quantitative real time PCR (qRT-PCR). Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis for the differentially expressed mRNAs indicated involvement of many, such as Jak-STAT, PI3K-Akt and NF-kappa B signaling pathways. To better understand the molecular basis of 5-FU-based CRR in CRC cells, correlated expression networks were constructed based on 8 intergenic lncRNAs and their nearby coding genes. Conclusions: Changes in lncRNA expression are involved in 5-FU-based CRR in CRC cells. These findings may provide novel insight for the prognosis and prediction of response to therapy in CRC patients.

  • The purpose of this study was to evaluate the effect of specific head positions on the mandibular rotational torque movements in maximum mouth opening, protrusion and lateral excursion. Thirty dental students without any sign or symptom of temporomandibular disorders(TMDs) were included as a control group and 90 patients with TMDs were selected and examined by routine diagnostic procedure for TMDs including radiographs and were classified into 3 subgroups : disc displacement with reduction, disc displacement without reduction, and degenerative joint disease. Mandibular rotational torque movements were observed in four head postures: upright head posture(NHP), upward head posture(UHP), downward head posture(DHP), and forward head posture(FHP). For UHP, the head was inclined 30 degrees upward: for DHP, the head was inclined 30 degrees downward: for FHP, the head was positioned 4cm forward. These positions were adjusted with the use of cervical range-of-motion instrumentation(CROM, Performance Attainment Inc., St. Paul, U.S.A.). Mandibular rotational torque movements were monitored with the Rotate program of BioPAK system (Bioresearch Inc., WI, U.S.A.). The rotational torque movements in frontal and horizontal plane during mandibular border movement were recorded with two parameters: frontal rotational torque angle and horizontal rotational torque angle. The data obtained was analyzed by the SAS/Stat program. The obtained results were as follows : 1. The control group showed significantly larger mandibular rotational angles in UHP than those in DHP and FHP during maximum mouth opening in both frontal and horizontal planes. Disc displacement with reduction group showed significantly larger mandibular rotational angles in DHP and FHP than those in NHP during lateral excursion to the affected and non-affected sides in both frontal and horizontal planes(p<0.05). 2. Disc displacement without reduction group showed significantly larger mandibular rotational angles in FHP than those in any other head postures during maximum mouth opening as well as lateral excursion to the affected and non-affected sides in both frontal and horizontal planes. Degenerative joint disease group showed significantly larger mandibular rotational angles in FHP than those in any other head postures during maximum mouth opening, protrusion and lateral excursion in both frontal and horizontal planes(p<0.05). 3. In NHP, mandibular rotational angle of the control group was significantly larger than that of any other patient subgroups. Mandibular rotational angle of disc displacement with reduction group was significantly larger than that of disc displacement without reduction group during maximum mouth opening in the frontal plane. Mandibular rotational angle of disc displacement without reduction group was significantly larger than that of disc displacement with reduction group or degenerative joint disease group during maximum mouth opening in the horizontal plane(p<0.05). 4. In NHP, mandibular rotational angles of disc displacement without reduction group were significantly larger than those of the control group or disc displacement with reduction group during lateral excursion to the affected side in both frontal and horizontal planes. Mandibular rotational angle of disc displacement without reduction group was significantly smaller than that of the control group during lateral excursion to the non-affected side in frontal plane. Mandibular rotational angle of disc displacement without reduction group was significantly larger than that of disc displacement with reduction group during lateral excursion to the non-affected side in the horizontal plane(p<0.05). 5. In NHP, mandibular rotational angle of the control group was significantly smaller than that of disc displacement with reduction group or disc displacement without reduction group during protrusion in the frontal plane. Mandibular rotational angle of disc displacement without reduction group was significantly larger than that of the disc displacement with reduction group or degenerative joint disease group during protrusion in the horizontal plane. Mandibular rotational angle of the control group was significantly smaller than that of disc displacement without reduction group or degenerative joint disease group during protrusion in the horizontal plane(p<0.05). 6. In NHP, disc displacement without reduction group and degenerative joint disease group showed significantly larger mandibular rotational angles during lateral excursion to the affected side than during lateral excursion to the non-affected side in both frontal and horizontal planes(p<0.05). The findings indicate that changes in head posture can influence mandibular rotational torque movements. The more advanced state is a progressive stage of TMDs, the more influenced by FHP are mandibular rotational torque movements of the patients with TMDs.

  • After the investigation on, and the analysis of, the educational system for medical technicians and the present educational situation for medical technologies in this country, the following conclusions were drawn. 1. As of March 1983 the current academic system for education in medical technologies included the regular 4-year college courses and those of the 2-year professional junior college courses. But except in the cases on clinical pathology and physical therapy, there were no college-level departments. Particularly, no educational institutions, at whatever level, had a department for working therapies. 2. The total number of credits needed for graduation from a department of medical technologies was 150 points at a regular 4-year college and 85 to 96 points at a 2-year professional college. The obligatory minimum number of credits for a student at a professional college was set at 80 points and above. 3. As for the number of the educational institutions for medical technologies in this country, there were one regular college and 14 professional colleges, a total of 15 institutions. As many as 14 colleges had departments of clinical pathology, 12 had departments of Radiotechnology, 11 had departments of physical therapy, 12 had departments of dental technology, and eight had departments of dental hygiene. 4. The total capacity of the professional colleges in admitting new enrollment each year were 1,920 for clinical pathology, 1,552 for radiology, 1,012 for physical therapy, 1,334 for dental technologies, 828 for dental hygiene, an aggregate of 6,646 for all of the professional college departments. 5. The total number of graduates from the 12 professional colleges by department during the period of 1965-83 were 7,595 for clindical pathology, 4,768 for radiology, 2,821 for physical therapy, 3,000 for dental technologies, and 1,787 for dental hygiene, totalling 19,971 for all departments in the professional colleges. 6. In the state examination for licensed medical technicians, 12,446 have passed from among the total of 26,609 participants, representing a 45% passing ratio. By departments the ratios showed 44% for clinical pathology, 39.7% for radiology, 51.2% for physical therapy, 42.5% for dental technology, 72.5% for dental hygiene and 73.1% for working therapy. 7. As for the degree of satisfaction shown by the people in this field, 52.2 percent of the teaching staffs who responed to the questionaires said they were satisfied with their present profession, while the great majority of medical technicians(66%) replied that they were indifferent to the problem. 8. The degree of satisfaction shown by the students on their enrollment in this particular academic field was generally in the framework of indifference(43.7%), but mere students(36.5%) were satisfied with their choice than those were not satisfied(14.4%) 9. As for the student's opinions on the lectures and practicing hours, a good many students replied that, among such courses as general science and humanities courses the basic medical course, the major course and practicing hours, the hours provided for the general courses(47.1%) and practicing(47.6%) were insufficient. 10. When asked about the contents of their major courses, comparatively few students (23.6%) replied that the courses were too difficult, while a convincing majority(58.5%) said they were neither difficult nor easy. As for the appropriateness of the number of the present teaching staffs, a great majority(71.0%) of the students replied that the level of the teaching personnel in each particular field was insufficient. 11. Among the students who responded to the poll, good part of them(49.5%) wanted mandatory clinical practicing hours, and the the majority of them(64.6%) held the view that the experimental and practicing facilities of their schools were insufficient. 12. On the necessity of the attached hospitals, 71.1% of the teaching staffs and 58.0% of the medical technicians had the opinion that this kind of facility was indispensable. 13. As for the qualifications for applicants to the state examination in the licensing system for medical technicians, 52.2% of the teacher's and 36% of the medical technicians replied that the present system granting the qualifications according to the apprenticeship period should be abolished. 14. On the necessity of improving the present system for education in medical technologies, an overwhelming majority(94.4% of the :caching staffs, 92.0% of the medical technicians and 91.9% of students) of these polled replied that the present system should be changed for the better. 15. On the method of changes for the present educational system, a great majority(89.4% of the teaching staffs, 80.4% of the medical technicians and 90.1% of the students) said that the system must be changed so that it fits into the reality of the present day. 16. As for the present 2-year program for the professional colleges, 61.6% of the teachers, 72.0% of the medical technicians and 38.8% of the students expressed the hope that the academic period would be extended to four regular years, hemming a full-fledged collegelevels program. 17. On the life-long eductional system for medical technicians, there was a considerable number of people who expressed the hope that an open university system(38.9% of the teaching staffs, 36.0% of the medical technicians) and a graduate school system would be set up. 18. As for the future prospects for medical technicians as professionals, the optimists ana pessimists were almost equally divided, and 41.1% of the teaching staffs 36.0% of. the technicians and 50.5% of the students expressed an intermediate position on this issue.

  • Withe increased North Korea's security threats, the South Korean navy has been faced with deteriorating security environment. While North Korea has increased asymmetric forces in the maritime and underwater with the development of nuclear weapons, and China and Japan have made a large investment in the buildup of naval forces, the power of the Pacific fleet of the US, a key ally is expected to be weakened. The biggest threat comes from China's intervention in case of full-scale war with North Korea, but low-density conflict issues are also serious problems. North Korea has violated the Armistice Agreement 2,660 times since the end of Korean War, among which the number of marine provocations reaches 1,430 times, and the tension over the NLL issue has been intensifying. With tension mounting between Korea and Japan over the Dokdo issue and conflict escalating with China over Ieo do Islet, the US Navy has confronted situation where it cannot fully concentrate on the security of the Korean peninsula, which leads to need for strengthening of South Korea's naval forces. Let's look at naval forces of neighboring countries. North Korea is threatening South Korean navy with its increased asymmetric forces, including submarines. China has achieved the remarkable development of naval forces since the promotion of 3-step plan to strengthen naval power from 1989, and it now retains highly modernized naval forces. Japan makes an investment in the construction of stat of the art warship every year. Since Japan's warship boasts of its advanced performance, Japan's Maritime Self Defense Force is evaluated the second most powerful behind the US Navy on the assumption that submarine power is not included in the naval forces. In this situation, naval power construction of South Korean navy should be done in phases, focusing on the followings; First, military strength to repel the energy warship quickly without any damage in case of battle with North Korea needs to be secured. Second, it is necessary to develop abilities to discourage the use of nuclear weapons of North Korea and attack its nuclear facilities in case of emergency. Third, construction of military power to suppress armed provocations from China and Japan is required. Based on the above naval power construction methods, the direction of power construction is suggested as follows. The sea fleet needs to build up its war potential to defeat the naval forces of North Korea quickly and participate in anti-submarine operations in response to North Korea's provocations. The task fleet should be composed of 3 task flotilla and retain the power to support the sea fleet and suppress the occurrence of maritime disputes with neighboring countries. In addition, it is necessary to expand submarine power, a high value power asset in preparation for establishment of submarine headquarters in 2015, develop anti-submarine helicopter and load SLAM-ER missile onto P-3C patrol aircraft. In case of maine corps, division class military force should be able to conduct landing operations. It takes more than 10 years to construct a new warship. Accordingly, it is necessary to establish plans for naval power construction carefully in consideration of reality and future. For the naval forces to safeguard maritime sovereignty and contribute to national security, the acquisition of a huge budget and buildup of military power is required. In this regard, enhancement of naval power can be achieved only through national, political and military understanding and agreement. It is necessary to let the nation know that modern naval forces with improved weapon system can serve as comprehensive armed forces to secure the command of the sea, perform defense of territory and territorial sky and attack the enemy's strategic facilities and budget inputted in the naval forces is the essential source for early end of the war and minimization of damage to the people. If the naval power construction is not realized, we can be faced with a national disgrace of usurpation of national sovereignty of 100 years ago. Accordingly, the strengthening of naval forces must be realized.

  • Hulled and naked oat is a perspective crop for the low input production systems due to its low requirements for soil quality and nutrition. Oats have good competitive ability against weeds and can provide appropriate yield in organic farming in comparison with other cereal species such as wheat or barley. It is a perspective crop from the point of view of use in the food industry too. The aim of our study was to compare the production and quality parameters of naked and hulled oat grown in both organic (OF) and conventional fields (CF). Small plot trials were conducted in two locations in the Czech Republic (České Budějovice, Prague) for four years (2018-2021) in two production systems (OF, and CF). We used four varieties of hulled oat (Korok, Kertag, Raven, Seldon) and one variety of naked oat (Patrik). During the vegetation, agronomically important data were recorded. After harvest samples were processed in the laboratory and analyzed selected quality parameters of grain dry matter (the protein content was determined by the Kjeldahl method, starch content in grain according to Ewers, fat content in grain dry matter by the modified method according to Soxhlet, and ash content in grain dry matter). The data were evaluated using the program STATISTICA version 13.2, StatSoft, Inc., California, USA. It is clear from the results that the number of panicles before the harvest was influenced by the location, cultivation system, year, and, to a lesser extent, the influence of the variety. The number of panicles in OF averaged 340 per square meter, which was 90% of the value of CF. For thousand grain weight (TGW), a significantly predominant effect of year was found. The independent effect of location on TGW was statistically not significant. Grain yield was predominantly influenced by cultivation system and location. In OF, it reached an average of 3.97 t.ha-1, which was 75% of the yield of CF. As part of the evaluation of the basic grain quality indicators, the content of protein, starch, fat, and ash in the dry matter of the grain was evaluated. The content of protein in the dry matter of the grain was predominantly influenced by year, followed by the influence of the variety and a fairly comparable influence of the cultivation system and locality. On average, it achieved 16.05% in OF and 17.01% in CF. The starch content was then related to the protein content, where as a result of the lower protein content in the grain of OF oats, the content of starch and fat was on the contrary increased. The year turned out to be the most significant factor, affecting both the starch content in the dry matter of the grain and the fat content. This was followed again by a fairly comparable influence on the cultivation system and locality. The influence of the cultivation system and location was not statistically significantly applied in the case of ash content in dry matter. Based on our results we can propose both types of oat (hulled and naked) as perspective crops for OF. An organic farmer can expect to achieve stable yields which, in less favorable conditions for the production of cereals in the OF, may be close to the level of conventional yields. In the future, it will be important to change agrotechnology in OF and increase oat yield because this crop has a good potential to grow in areas with low nitrogen input or less fertile soil.

  • 토지국유원칙(土地國有原則)을 표방(標榜)하고 "공사(公私) 공리(共利)"를 기본원칙(基本原則)으로 하고 있었던 고려조(高麗朝)의 시전과제도(柴田科制度)도 집권력(執權力)의 약화(弱化)로 인(因)하여 조만간(早晩間), 붕괴(崩壞)되고 말았던 것이나 임지제도(林地制度)에 있어서는 분묘설정(墳墓設定)의 자유(自由)와 개간장려(開墾奬勵)를 이용(利用)한 삼림(森林)의 광점(廣占) 및 전시과제도(田柴科制度)로 인(因)한 시지(柴地)의 수조권위양(收租權委讓)으로 유래(由來)된 사적수조권(私的洙組權)이 결부(結付)된 삼림(森林)의 사점현상등(私占現象等)이 점차(漸次) 발전(發展)하여 고려중기(高麗中期)의 국정해지기이후(國政解地期以後)에는 대부분(大部分)의 삼림(森林)이 권력층(權力層)의 사점지(私占地)로 화(化)하여 왔었다. 고려조(高麗朝)의 모든 제도(制度)를 그대로 계승(繼承)한 이조(李朝)는 건국후(建國後) 국가소용(國家所用)의 삼림확보(森林確保)를 위(爲)한 삼림수용(森林收用)의 제도확립(制度確立)이 긴요(緊要)하였음으로 전국(全國)의 삼림(森林)을 국가권력(國家權力)에 의(依)하여 공수(公收)하고 국가(國家)와 궁실소용이외(宮室所用以外)의 모든 삼림(森林)은 사점(私占)을 금(禁)한다는 "시장사점금지(柴場私占禁止)"의 제도(制度)를 법제화(法制化)하였고 도성주변(都城周邊)의 사산(四山)을 금산(禁山)으로 함과 아울러 우량(優良)한 임상(林相)의 천연림(天然林)을 택(擇)하여 전조선용재(戰漕船用材)와 궁실용재(宮室用材)의 확보(確保)를 위(爲)한 외방금산(外方禁山)으로 정(定)하고 그 금양(禁養)을 위(爲)하여 산직(山直)을 배치(配置)하였다. 그리고 연병(練兵)과 국왕(國王)의 수렵(狩獵)을 위(爲)한 강무장(講武場)과 관용시장(官用柴場), 능원부속림(陵園附屬林)의 금벌(禁伐), 금화(禁火)를 제정(制定) 등(等) 필요(必要)에 따라 수시(隨時)로 삼림(森林)을 수용(收用)하였으나 고려조이래(高麗朝以來)로 권력층(權力層)에 의(依)하여 사점(私占)되어온 삼림(森林)을 왕권(王權)으로 모두 공수(公收)하지는 못하였던 것이다. 이조초기(李朝初期)에 있어서의 집권층(執權層)은 그 대부분(大部分)이 고려조(高麗朝)에서의 권력층(權力層)이었던것 임으로 그들은 이미 전조시대(前朝時代)로부터 많은 사점림(私占林)을 보유(保有)하고 있었던 것이고 따라서 그들이 권력(權力)을 장악(掌握)하고 있는 한(限) 사점림(私占林)을 공수(公收)한다는 것은 어려운 일이었으며 그들은 오히려 권력(權力)을 이용(利用)하여 사점림(私占林)을 확대(擴大)하고 있었던 것이다. 또 왕자(王子)들도 묘지(墓地)를 빙자(憑藉)하여 주(主)로 도성주변(都城周邊)의 삼림(森林)을 광점(廣占)하고 있던 터에 성종(成宗)의 대(代) 이후(以後)로는 왕자신(王自身)이 금령(禁令)을 어기면서 왕자(王子)에게 삼림(森林)을 사급(賜給)하였음으로 16세기말(世紀末)에는 원도지방(遠道地方)에 까지 왕자(王子)들의 삼림사점(森林私占)이 확대(擴大)되었고 이에 편승(便乘)한 권신(權臣)들의 삼림사점(森林私占)도 전국(全國)으로 파급(波及)하였다. 임진왜란후(壬辰倭亂後)에 시작(始作)된 왕자(王子)에 대(對)한 시장절급(柴場折給)은 삼림(森林)의 상속(相續)과 매매(賣買)를 합법화(合法化)시켰고 이로 인(因)하여 봉건제하(封建制下)에서의 사유림(私有林)을 발생(發生)시키게 된 것이다. 그리하여 권신(權臣)들도 합법적(合法的)으로 삼림(森林)을 사점(私占)하게 되었고 따라서 이조시대(李朝時代) 임지제도(林地制度)의 기본(基本)이었던 시장사점금지(柴場私占禁止)의 제도(制度)는 건국초(建國初)로부터 실행(實行)된 일이 없었으며 오로지 국가(國家)의 삼림수용(森林收用)을 합법화(合法化)시키는 의제(擬制)에 불과(不過)하였던 것이다. 금산(禁山)은 그 이용(利用)과 관리제도(管理制度)의 불비(不備)로 인(因)하여 산하주민(山下住民)들의 염오(厭惡)의 대상(對象)이 되었음으로 주민(住民)들의 고의적(故意的)인 금산(禁山)의 파괴(破壞)는 처음부터 심(甚)하였고 이로 인(因)하여 국가(國家)에서는 용재림확보(用材林確保)를 위(爲)한 금산(禁山)의 증설(增設)을 거듭하였으나 관리제도(管理制度)의 개선(改善)이 수반(隨伴)되지 않았음으로 금산(禁山)의 황폐(荒廢)는 더욱 증대(增大)되었다. 영조(英祖)는 정국(政局)을 안정(安定)시키기 위(爲)하여 경국대전이후(經國大典以後) 남발(濫發)된 교령(敎令)과 법령(法令)을 정비(整備)하여 속대전(續大典)을 편찬(編纂)하고 삼림법령(森林法令)을 정비(整備)하여 도성주변(都城周邊)의 금산(禁山)과 각도(各道) 금산(禁山)의 명칭대신(名稱代身) 서기(西紀) 1699년(年) 이후(以後) 개칭(改稱)하여온 봉산(封山)의 금양(禁養)을 강화(强化)시키는 한편 사양산(私養山)의 권한(權限)을 인정(認定)하는 등(等) 적극적(積極的)인 육림정책(育林政策)을 퍼려하였으나 계속적(繼續的)인 권력층(權力層)의 삼림사점광대(森林私占廣大)는 농민(農民)들로부터 삼림(森林)을 탈취(奪取)하였고 농민(農民)들 이 삼림(森林)을 상실(喪失)함으로써 국가(國家)의 육림장려등(育林奬勵策)은 효과(効果)를 나타내지 못하였던 것이다. 임진왜란후(壬辰倭亂後)의 국정해이(國定解弛)로 인(因)한 묘지광점(墓地廣占), 왕자(王子)에 대(對)한 삼림(森林)의 절급(折給) 권세층(權勢層)에 대(對)한 산림사점(森林私占)은 인허(認許)하는 입안문서(立案文書)의 발행등(發行等)으로 법전상(法典上)의 삼임사점금지조항(森林私占禁止條項)은 사문화(死文化)되었고 이조말기(李朝末期)에 있어서는 사양산(私養山)의 강탈(强奪)도 빈발(頻發)하고 있음을 볼수 있다. 이와 같이 이조시대(李朝時代)의 시장사점금지조항(柴場私占禁止條項)은 오로지 농민(農民)에게만 적용(適用)되는 규정(規定)에 불과(不過)하였고 이로 인(因)하여 농민(農民)들의 육림의욕(育林意慾)은 상실(喪失)되었으며 약탈적(掠奪的)인 삼림(森林)의 채취이용(採取利用)은은 금산(禁山), 봉산(封山) 및 사양산(私養山)을 막론(莫論)하고 황폐(荒廢)시키는 결과(結果)를 자아냈으며 권력층(權力層)의 삼림점탈(森林占奪)에 대항(對抗)한 송계(松契)의 활동(活動)으로 일부(一部) 공산(公山)이 농민(農民)의 입회지(入會地)로서 보존(保存)되어왔다. 그럼에도 불구(不拘)하고 일제(日帝)는 이조말기(李朝末期)의 삼림(森林) 거의 무주공산(無主公山)이 었던것처럼, 이미 사문화(死文化)된 삼림사점금지조항(森林私占禁止條項)을 활용(活用)함으로써, 국가림(國有林)으로 수탈(收奪)한후(後) 식민정책(植民政策)에 이용(利用)하였던 것이나, 실제(實際)에 있어서 이조시대(李朝時代)의 삼림(森林)은 금산(禁山), 봉산(封山), 능원부속림등(陸園附屬林等)의 관금지(官禁地)와 오지름(奧地林)을 제외(除外)하고는 대부분(大部分)의 임지(林地)가 권세층(權勢層)의 사유(私有) 내지(乃至)는 사점하(私占下)에 있었던 것이다.
