The administrative service in Chosun Dynasty relating to mathematics was carried out by the middle class(中人) mathematicians selected by the official selection examination(取才). They belong to HoJo(戶曹) department and their ranks are GyeSa(計士), ByulJe(別提), HunDo(訓導 = mathematics teacher), and GyoSu(敎授 = mathematics professor). We call them SanWon(算員). HunDo and GyoSu played very important role although their ranks are low, for they educate SanWon and manage the official selection examination. Using JuHakSeonSaengAn(籌學先生案, List of mathematics teachers) and JuHakIpGyukAn(籌學入格案, List of successful candidates in the official selection examination for mathematics), we investigate HunDo and GyoSu in Chosun Dynasty.

현대 경찰활동은 경찰공무원의 개인에 의한 자질과 역량이 중요한 부분이기도 하지만 조직구성원의 상호관계를 통해서 이루어지고 있다. 경찰의 주된 업무는 범죄의 예방과 사회질서를 담당하고 있으며 이는 지역사회 경찰활동이라는 새로운 패러다임의 적용을 통해서 더욱 활발히 추진되고 있다. 그러한 맥락으로 경찰 조직은 일반 국민에 대한 봉사와 서비스를 통하여 고객에 대한 만족을 이루고자 노력하고 있다. 그러나 여기에서에서 간과되어서는 안 될 부분이 조직내부의 구성원이다. 조직구성원인 경찰공무원에 대한 이해 없이는 일반 국민에게 만족스러운 경찰활동은 기대하기가 어렵다. 따라서 본 연구에서는 경찰공무원 중에서 외근 업무를 담당하고 있는 경찰공무원의 조직효과성 인식 차이를 살펴보고자 하였다. 그 결과, 성별, 연령, 근무지역, 경찰서 급지별, 계급, 근무기간에 따라서 외근 경찰공무원의 조직효과성 인식은 유의미한 차이가 있는 것으로 조사되었다.

'Needle-embedding therapy', also called 'Acupoint Embedding Therapy' is the newly induced therapy which uses specialized tools. Embedded alien substance stimulates the acupoint and helps to keep the stimulation up. Needle-embedding therapy is mainly used for chronic diseases and deficiency syndromes, and also for other diseases including acute pain and excessive syndromes. Recently, clinical doctors are studying this therapy vigorously on the foundation of 'theory of meridian pathway' and applying for facial and body esthetics such as face-lift, correction skin troubles, depilation and so on. In spite of all these effect, theories for 'Needle-embedding Therapy' doesn't seem clearly arranged yet. So we, here, present the philological basis of 'Needle-embedding Therapy' from referring to old records and newly publicated papers and consider the new trend of this therapy in Korean and China.

Objectives : The aim of this study was identification of the anti-oxidative and anti-inflammatory effects of Talmyung-san (TMS) in mouse macrophage, RAW264.7 cells. Methods : To identify the anti-oxidative effect of TMS, scavenging activities of DPPH radical, nitric oxide and peroxynitrite were measured in vitro. In RAW264.7 cells, DCFH-DA assay was conducted to examine the inhibitory effect of TMS on ROS production in response to lipopolysaccharide. And the productions of nitric oxide (NO), $PGE_2$ and pro-inflammatory cytokines were measured. The levels of COX-2, iNOS, nuclear NF-${\kappa}B$ p65 expression and phosphorylation of $I{\kappa}B-{\alpha}$ in cytosol were detected by western blotting analyses. Results : TMS couldn't scavenged DPPH radical, but nitric oxide and peroxynitrite were decreased. TMS decreased intracellular ROS, NO, and IL-$1{\beta}$ production effectively. However, TMS inhibited $PGE_2$ levels only in high concentration ($300{\mu}g/m{\ell}$) and TMS failed to suppress the production of IL-6 and TNF-${\alpha}$. Results from immunoblot analyses revealed that TMS decreased activation of COX-2, iNOS, phosphorylation of $I{\kappa}B-{\alpha}$ and nuclear translocation of p65. Conclusions : TMS has anti-RNS and anti-inflammatory effects via NF-${\kappa}B$ pathway and more intensive studies will be required to evaluate therapeutic potential of TMS.

The aim of the present investigation was to see the effect of combined use of PDGF BB and IGF -1 on the guided tissue regeneration(GTR) using barrier membrane in the treatment of human furcation involvement. Twelve patients with initially diagnosed as having moderate to advanced adult periodontitis with mandibular class II buccal furcation defects have been wer selected. Initial scaling and root planing has been performed and baseline data consisting of probing depths and attachment levels have been recorded prior to surgical procedures. The GTR procedures using either barrier membrane(control : ePTFE) alone or together with the application of PDGF - BB and IGF -l(experimental : ePTFE+PDGF/IGF) have been done under the routine guidelines. During the surgery, the distance from CEJ either to the bottom of the bone defects(CEJ - BD) or to the bone crest(CEJ-BC) were measured. Horizontal distance to the deepest area in the furcal defects were measured from the reference line connection the most prominent bony walls of the two buccal roots. 6 months following the GTR therapy, all the measurements were made repeatedly. The probing attachment gain of the experimental and the control grous were 2.14mm and l.07mm, respectively with no statically significnant difference. Amont of vertical bone fill in the experimental and the control groups were 2.43mm and 2.29mm, rexpectively. Amonut of horizontal bone fill were 2.86mm in the experimental group and 2.17mm in the control group, respectively. However, there were no significant differences in the amount of bone fill(both vertical and horizontal)between the two groups.

Objectives Danggwisoo-san and Jakyakgamcho-tang are frequently prescribed for traffic accident patients in Korea. The aim of this study was to examine index compound analysis, antioxidant activity and amount of starch measurement by extraction method. Methods Danggwisoo-san and Jakyakgamcho-tang were extracted with water and 70% ethanol. Antioxidant activity was measured by 2,2-Diphenyl-1-picrylhydrazyl, 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and ferric reducing antioxidant power according to the standard protocol. The contents of the indicator components nodakenin, paeoniflorin, and glycyrrhizin were measured by high-performance liquid chromatography, respectively. All starches were hydrolyzed and then total D-glucose was measured and compared. Results Antioxidant activity was excellent in 70% ethanol in all assays. The index component was jagged because its solubility was different depending on the extraction solvent. Starch content was significantly lower in 70% alcohol extract than water extract. Conclusions The results of this study showed that physiological activities and components are different according to extraction conditions. Each herbal medicine has a suitable extraction solvent. Also, the difference in starch content is an object to be considered as it may affect digestion and absorption.

Objectives : This study was to observe the nephroprotective effects of the traditional prescription, Taeksa-san(TSS). TSS has generally been used for treating various renal diseases, including renal failure. Methods : Three different dosages of TSS extract were orally administered once a day for 28 days, At the 23rd day after TSS extract treatment, cisplatin was also treated. Then, 5 days after cisplatin treatment, all the rats (6 groups of 8 rats each) were sacrificed. Changes in the body weight, kidney weight, serum BUN and creatinine levels were observed with changes on the kidney MDA and GSH contents. The results were compared with captopril 100mg/kg, of which the effects on cisplatin-induced acute renal failures are already confirmed. Results : Dramatic decrease of body weight, increase of kidney weight, increase of serum BUN and creatinine levels were detected in the cisplatin control as compared with the intact control. In addition, marked increase of kidney MDA contents and decrease of kidney GSH contents were also detected in the cisplatin control as compared with the intact control. This means that cisplatin-induced ARF is induced by oxidative stress and related lipid peroxidation in the present study. However, these ARFs and inhibition of antioxidant effects induced by cisplatin were dose-dependently reduced by treatment with all three different dosages of TSS extracts. Conclusion : This study suggests that TSS extracts show favorable effects on cisplatin-induced rat ARF.

Objectives: This study conducted a retrospective review to compare the effectiveness of herbal medicine, while confirming the effectiveness of Korean medicine (KM) in traffic accidents (TA). Methods: We investigated the medical records of TA patients who were hospitalized at Muuido Korean medicine hospital from January 2016 to June 2018 retrospectively. Medical records included general characteristics (Gender, age), TA & treatment-related information (Collision type, chief complaint, hospitalization period, and herbal medicine prescription), and clinical scales (Five-scale improvement, numerical rating scale (NRS)). Statistical analysis was performed for data distribution and effectiveness comparison. Results: 755 TA patients showed 0.78:1 gender ratio. 20-50s years old, rear collision, pain in the cervical and lumbar spine, and hospitalization period within 14 days were the majority. KM improved 83.18% of 755 TA patients' symptoms and ROM over 'improvement' level, which indicated 30-70% improvement. With common KM treatments including acupuncture, cupping, heat therapy, and manipulation therapy, TA patients received various herbal medicines and herbal medicine for breaking severe blood stasis (Tongdo-san) showed improvement in both five-scale improvement and NRS change at the same time. Conclusions: We could confirm the effectiveness of KM, particularly herbal medicine in TA. It would be necessary to develop new herbal medicines such as Tongdo-san to treat TA-related symptoms.

The present study was performed to elucidate the therapeutic effect by aquapuncture with bee-venom (apitoxin) for treatment of canine pyoderma. The total 8 dogs with pyoderma were divided into 2 groups as control (antibiotics group: 4 dogs) and experimental groups (apitoxin group: 4 dogs). Antibiotics group was treated with bathing and antibiotics, while apitoxin group was treated with bathing and aquapuncture with apitoxin at Fei Shu (BL13), Wei Zhong (BL40), Da Zhui (GV14), Zu San Li (ST36), He Gu (LI04), Qu Chi (LI11), and San Yin Jiao (SP06). Based on the results of changes in clinical symptoms, total leukocyte counts, neutrophil/lymphocyte ratios and histopathological findings, antibiotics and apitoxin groups were all effective for treatment of canine pyoderma, and significant differences were not detected between the groups. It was suggested that apitoxin might be used as an alternative method to antibiotics for treatment of canine pyoderma.
