Background: Standardized procedures for the clinical application of fire cupping methods have not been established. In particular, the pressure parameters have not been fully characterized and described. Therefore, using various materials, this study investigated the pressure range exerted during fire cupping therapy. Methods: In this study, 3 differently sized (small, medium, large) glass and bamboo cups were used in the cotton ball fire cupping procedure to measure the pressure inside the cup applied to a human skin model. The pressure in each cup was measured 15 times for a total of 90 measurements. Results: A small bamboo cup had the minimum overall pressure (-305.4 mmHg), whereas the large glass cup exerted the maximum pressure (-401.3 mmHg), followed by the medium glass cup, large bamboo cup, small glass cup, and medium bamboo cup. The average pressure exerted by the cotton ball method for all cups ranged from -348.715 mmHg to -358.694 mmHg (95% confidence interval). Overall, the glass cups had a greater pressure than the bamboo cups in all groups (p < 0.001). Among the glass cups used, the larger the size of the cup, the higher the average pressure detected (-381.947 mmHg to -391.973 mmHg; p < 0.05). Conclusion: Large glass cups which are widely used in clinical practice, when used in the fire cupping method exerted pressure ranging from -381.947 mmHg to -391.973 mmHg (95% CI).

Najang was the central Seori, affiliated to the Ministry of War during the Joseon dynasty. The objective of this study is to research the existing authentic Najang costumes from the late-Joseon dynasty by examining factors, such as the composition of the costume, size, and method of creation, and attempt to replicate it. The Leipzig Grassi Museum in Germany possesses an official uniform of Najang from the late-Joseon dynasty, and we visited the museum in May of 2013 to examine it for the study. Written records, or Uigwe, and other pictorial data from the Joseon Dynastry describe the Najang wearing black or navy clothing with white decoration and pointy hats. The most notable characteristic of the Najang uniform is that it has the cotton cords pattern. The hat has a brass ball attached, which was worn with the ball facing the front in the early Joseon Dynasty, and was worn facing the back in the later years. They usually wore black head cloths (Heuk-geon), but would attach feathers on the black hats (Heuk-rip) for special occasions. The Najang uniform preserved in the Leipsiz Grassi Muesim does not exist in Korea. It is made of cotton. The cotton cord pattern of the uniform of Najang was made using single-ply cords and double-ply cords. The hat worn by Najang is in a form of a cone that becomes narrower towards the top or is in a form with wide and open end. It was made of oiled paper covered with hemp, and two circular metal disks were attatched at the rear.

The purpose of this research is to study doll's symbolism representing our social culture and the characteristics of clothing design. The ball joint doll was selected, that are pretty much resembled to human body in terms of facial expression, body proportion, joint movement, etc. Results of research are summarized as follows: the ball joint doll is indicated a doll whose joints are free to move with a round shaped joint, which originated by Yochilya simon, who adopted German Hans Bellmer's method.'rho ball joint doll, first, there appeared state of human isolation due to the material civilization and industrial revolution, and trend of adhering to one's own world made human possess dolls. Second, according to the doll play became a representing play culture among Kidult culture, dolls, that are resembled with human being, were recognized as personalized objects. Third, along of expanding digital culture that makes easy to exchange information via Internet, so, ball joint doll market is growing fast, for which various levels of mania are being formed. Take a look at the doll fashion in modern society. In accordance to form of Look, it is largely categorized Young Casual look, Office look, Ethnic look and Military look. When take a look at design specialty, young casual look was presented as a comfortable silhouette and also made of elastic materials and expressed vivid bright tones. Office look image was expressed as a suit of jacket with skirt, and cotton wool polyester materials and acro-matic colors. Ethnic look was represented by Japanese traditional dress and Chinese traditional clothing. The Military look was generally emphasized army uniforms of straight silhouette and shoulder straps.

시아노아크릴레이트 훈증법은 비다공성 표면에 유류된 잠재지문을 현출할 때 효과적이다. 본 연구는, 진공챔버에서 시아노아크릴레이트를 훈증할 때 온도, 습도, 훈증 방법 등이 잠재지문 현출에 미치는 영향을 확인한 후 최적 반응 조건을 찾는데 있다. 진공챔버의 온도가 높을수록 시아노아크릴레이트 증발량은 증가했지만, 지문 융선에서 시아노아크릴레이트의 중합반응은 $30^{\circ}C$에서 가장 잘 일어났다. 상대습도가 40%, 50% 조건에서는 좋은 상태의 지문이 현출되었지만, 30%보다 낮거나 60%보다 높은 조건에서는 지문 융선에서 시아노아크릴레이트 중합반응 속도가 느려졌다. 진공챔버에서 시아노아크릴레이트를 자연적으로 증발시키는 방법보다는 $OMEGA-PRINT^{TM}$ dispersal pads와 수산화나트륨을 포함한 솜을 이용해 시아노아크릴레이트 훈증하는 방법이 효과적이란 사실을 확인할 수 있었다. 진공챔버에서 시아노아크릴레이트 처리시간은 상대습도에 비해 큰 영향을 주지 않았다.

Purpose: To evaluate the effect of intermittent bleeding method in the distal phalanx replantation. Materials and Methods: From January 2007 through June 2009, authors have replanted 117 cases of distal phalangeal amputation in adults at Soo Hospital and Chonbuk National University Hospital. Cases of zone II were 60 cases and zone III 57 according to Allen classification. Male to female ratio was 8.7:1.3. The most common cause was machinery injury in the factory, 98 cases(83.8%), next one was belt injury of the machine, 11 cases(9.4%) and others, 8(6.8%). At least one digital artery and digital nerve were anastomosed under the operating microscope, but vein was impossible to anastomosis as unable to find out in the zone II and III. After anastomosis of one or more digital arteries and nerves, heparine(6,000-10,000 units) was kept to intravenous injection for 24 hours and at the same time fish mouth incision in 2-3 millimeter diameter was made in the distal radial and ulnar margin of the replanted distal phanlanx. From the first 30 minutes to an hour after replantation, incision site was swabbed with heparinized cotton ball for 5 minutes in every 30 to 40 minutes to make sure perfusion for 24 hours, every an hour at the second day, every two hours at the postoperative third to fifth day. Results: 92 cases(78.6%) was completely survived at average postoperative third week follow-up and satisfied with preservation of the finger nail, digit length, good range of motion of the distal interphalangeal joint and acceptable sensibility at average 1.2 years follow-up. Conclusions: Intermittant bleeding method in replantation of crushed distal phalanx impossible to anastomosis of vein at zone II and III of Allen classification was regarded as one of the notable salvage procedure.

본 연구에서는 나노구조의 새로운 망간산화물 입자(즉, 블랙-버네사이트)를 합성하여 물질특성 및 1,4-naphthoquinone (1,4-NPQ)을 대상으로 반응매개체 존재 하에서의 산화-변환반응 효율을 조사하였고, 그 결과를 기존의 McKenzie 방법으로 얻은 망간산화물(즉, 브라운-버네사이트)의 결과와 비교 분석하였다. XRD 분석 결과 합성한 망간산화물 입자의 결정상은 버네사이트(${\delta}-MnO_2$)임을 확인하였으며, SEM 측정결과 입자표면은 섬유상의 구조에 의한 나노크기의 미세기공을 가진 볼모양(ball-like)의 형태를 보였다. 배치실험 결과, 나노구조의 망간산화물에 의한 1,4-NPQ 제거는 유사-1차 반응을 따랐으며 기존 망간산화물과 비교해 BET 비표면적 값이 작음(41.05 vs 19.80 $m^2/g$)에도 불구하고 약 2.3배의 높은 속도 상수값을 보였다. 이러한 결과는 블랙-버네사이트에서의 상대적으로 높은 결정성과 나노구조의 표면 특성에 기인한 것으로 해석되며, 블랙-버네사이트 입자가 퀴논화합물에 대하여 상대적으로 높은 반응성을 보임을 알 수 있다. 반응산물에 대한 HPLC 크로마토그램 분석 결과로부터 블랙 버네사이트 입자에 의한 1,4-NPQ의 제거는 반응 매개체인 catechol 존재 하에서의 상호-결합반응을 통한 중합체 생성을 통해 제거됨을 확인하였다.
