Purpose: In the case of repair for far distal parts of FDP (Flexor digitorum profundus) division, the method of either pull-out suture or fixation of tendon to the distal phalanx is preferred. In this paper, the results of a modified loop suture technique used for the complete division of FDP from both zone 1a and distal parts of zone 1b in Moiemen classification are presented. Methods: From July 2006 to July 2009, the modified loop suture technique was used for the 10 cases of FDP in complete division from zone 1a and distal parts of zone 1b, especially where insertion sites were less than 1 cm apart from a tendon of a stump. In a suture technique, a loop is applied to each distal and proximal parts of tendon respectively. Core suture of 2-strand and epitendinous suture are done with PDS 4-0. Out of 10 patients, the study was done on 6 patients who were available for the followup. The average age of the patients was 49.1 years (in the range from 26 to 67). 5 males and 1 female patients were involved in this study. There were 3 cases with zone 1a and distal parts of zone 1b. The average distance to the distal tendon end was 0.6 cm. There were 5 cases underwent microsurgical repair where both artery and nerve divided. One case of only tendon displacement was presented. The dorsal protective splint was kept for 5 weeks on average. The results of the following tests were measured: active & passive range of motion, grip strength test, key pinch and pulp pinch test. Results: The follow-up period on average was 11 months, in the range from 2 to 20 months. There was no case of re-rupture, but tenolysis was performed in 1 cases. In all 6 cases, the average active range of motion of distal interphalangeal joint was 50.8 degree. The grip strength (ipsilateral/contralateral) was measured as 88.7% and the pulp pinch test was 79.2% as those of contralateral side. Flexion contracture was presented in 2 cases (15 degree on average) and there was no quadrigia effect found. Conclusion: Despite short length of tendon from the insertion site in FDS rupture in zone 1a and distal parts of zone 1b, sufficient functional recovery could be expected with the tendon to tendon repair using the modified loop suture technique.

Purpose: Industrial punch accidents involving fingers cause segmental injuries to tendons and neurovascular bundles. Although multiple-level segmental amputations are not replanted to regain function, most patients with an amputated finger want to undergo replantation for cosmetic as much as functional reason. The authors describe four cases of digital amputation by an industrial punch that involved the reinstatement of the amputated finger involving a joint and neurovascular bundle. Amputated segments were replanted to restore amputated surfaces and distal segments. Methods: A single institution retrospective review was performed. Inclusion criteria of punch injuries requiring replantation were applied to patients of all demographic background. Injury extent (size, tissue involvement), operative intervention, pre- and postoperative hand function were recorded. Result: Four cases of amputations were treated at our institute from 2004 to 2008 from industrial punch machine injury. Average patient age was 32.5 years (25~39 years) and there were three males and one female. Sizes of amputated segments ranged from $1.0{\times}1.0{\times}1.2\;cm^3$ to $3{\times}1.5{\times}1.6\;cm^3$. Tenorrhaphy was conducted after fixing fractured bone of the amputated segments with K-wire. Proximal and distal arteries and veins were repaired using the through & through method. The average follow-up period was thirteen months (2~26 months), and all replanted cases survived. Osteomyelitis occurred in one case, skin grafting after debridement was performed in two cases. Because joints were damaged in all four cases, active ranges of motion were much limited. However, a secondary tendon graft enhanced digit function in two cases. The two-point discrimination test showed normal values for both static and dynamic tests for three cases and 9 mm and 15 mm by dynamic and static testing, respectively, in one case. Conclusion: Though amputations from industrial punch machines are technically challenging to replant, our experience has shown it to be a valid therapy. In cases involving punch machine injury, if an amputated segment is available, the authors recommend that replantation be considered for preservation of finger length, joint mobility, and overall functional recovery of the hand.

Pulmonary cryptococcosis is a non-infectious opportunistic or silent infection caused by Cryptococcus neoformans. It enters the body through the respiratory tract and spreads to lung, skin, liver, and lymphoid organs. Recently its incidence has been gradually increasing because of developing diagnostic tools, increased use of steroids and immunosuppressive drugs, increased survival rate of patients with chronic diseases, and increased incidence of immunodeficiency syndrome. We report a case of pulmonary cryptococcosis in a patient with rheumatoid arthritis who was being treated with low dose glucocorticoid, methotrexate and cyclosporine for 14 months.

본 연구는 4종의 재래닭인 연산오계, 현인흑계, 횡성약닭, 황봉의 일반성분, 카르노신, 안세린 함량 및 면역활성을 비교하기 위하여 실시하였고, 대조구로 백색 레그혼을 사용하였다. 시험용 닭을 모두 동일한 조건에서 13주간 사육하여 도계한 후 화학적 성분조사를 실시하였다. 일반성분 분석에서는 4종의 재래닭이 백색레그혼에 비하여 조지방 함량이 높았으며, 콜레스테롤 함량은 현인흑계가 다른 품종에 비하여 높았고 횡성약닭이 유의적으로 낮았다(p<0.05). 면역증진 효능을 측정하기 위하여 대식세포를 이용하여 실험한 결과는 재래닭 4종의 가슴육에서만 대식세포 증식 및 NO 억제효능이 있었다. 대식세포 탐식작용은 현인흑계와 횡성약닭가슴육에서 유의적으로 증가되었고, 염증 관련 사이토카인(IL-4, IL-10, IFN-γ) 유전자 발현은 백색레그혼에 비하여 4종의 재래닭에서 억제효과가 컸다. 결론적으로 4종류의 재래닭이 백색레그혼에 비하여 면역증진 효능이 높았으며, 특히 가슴육에서 효능이 있었다. 재래닭 품종 간에도 일반성분 및 면역조절능에 차이가 있는 것으로 나타났다. This study was conducted to compare the general composition and immunomodulatory activity of breast and thigh meats from four lines of Korean native chickens: Yeonsan Ogye, Hyunin Black, Hwangbong, and Hoengseong Yakdak. White Leghorn was used as a control. Fifteen male chickens (three chickens in each line) were grown under the same conditions and slaughtered at 13 weeks old. The four lines of Korean native chickens, regardless of the part, had higher contents of crude fat (p<0.05) than White Leghorn. The cholesterol contents were significantly higher in Hyunin Black and significantly lower in Hoengseong Yakdak than those of other chickens (p<0.05). The immunomodulatory effect, assessed by macrophage cell proliferation and nitric oxide production, was only observed in the breast meat of the four lines of Korean native chickens. The phagocytic activity of macrophage cells was significantly augmented by the breast meat of Hyunin Black and Hoengseong Yakdak. Furthermore, the mRNA expressions of pro-inflammatory cytokines, such as IL-4, IL-10 and IFN-γ, was significantly suppressed by Korean native chickens compared with White Leghorn. These results suggested that the four lines of Korean native chickens exhibited greater immune-enhancing activity than White Leghorn.

지역 부서장의 연고지 배치가 조직의 경영성과에 미치는 영향

이규철(Kyu-Cheol Lee) 한국공기업학회 2023 공기업논총 Vol.23 No.2

한국사회에 있어서 연고주의는 타 집단(outgroup)의 구성원을 차별하는 내적 귀속성과 외적 배타성이 강한 집합주의의 성향을 나타내고 있다. 이 논문은 K공사의 지역 부서장 연고지 배치가 조직 경영평가와 관련하여 실증적 통계자료를 통해 살펴 봄으로써 연고지 배치가 조직성과에 어떠한 영향을 미치는지 살펴보기로 하였다. 지역 부서장의 연고지 배치는 ‘청렴도 총점’ 성과에 양(+)의 영향을 미치는 것으로 나타났다. 지역 부서장의 연고지 배치는 직원 정보의 높은 이해도를 활용하여 적재적소 직원 인사 배치와 업무분장을 시행하는 것으로 분석되었다. 그리고 지역 부서장의 연고지 배치와 ‘반부패개선’ 성과 간에는 양(+)의 영향을 미치는 것으로 나타났다. 지역 부서장의 연고지는 조직 구성원들이 자발적으로 반부패 개선활동에 참여할 수 있는 동기부여와 조직몰입을 할 수 하도록 영향을 미친 것으로 분석되었다. 지역 부서장의 연고지 배치는 ‘지역개발 평가’ 성과에 양(+)의 영향을 미치는 것으로 나타났다. 지역 부서장의 연고지 배치가 지역 현안 사항 등 지역 정보에 대해 잘 알고 있어 지역개발 향상에 중요한 요인이 된 것으로 분석되었다. In Korean society, nepotism is a tendency of collectivism with strong internal attribution and external exclusivity that discriminates against members of outgroups. This paper examines the effect of nepotism on organizational performance through empirical and statistical data in relation to the organizational management evaluation of regional department heads of K Corporation. It was found that the location of the regional department head's relatives had a positive effect on the performance of the 'total integrity score'. It was analyzed that the regional department head's nepotism is analyzed as a way to utilize the high level of understanding of employee information to implement appropriate staffing and work division. In addition, there is a positive effect between the regional department head's nepotism and 'anti-corruption improvement' performance. It was analyzed that the regional department head's hometown influenced the motivation and organizational commitment of organization members to voluntarily participate in anti-corruption improvement activities. The location of the regional department head's hometown had a positive effect on the performance of the 'Regional Development Assessment'. It was analyzed that the placement of the regional department head's nepotism was an important factor in improving regional development because he/she was familiar with regional information such as regional issues.
