Background: In the field of dentistry, topical anesthetics play an important role in reducing pain during needle pricks. The anesthetic property of betel leaves remain unexplored, even though they have been widely used for the treatment of various ailments. The purpose of this study was to compare and evaluate pain perception following topical application of lignocaine gel, clove gel, ice, and newly developed betel leaf extract gel during intraoral injection in children. Methods: Sixty children aged 6-10 years who met the inclusion criteria were divided into four groups. Topical anesthetic agents, 2% lignocaine (Lox-2% Jelly, Neon, Mumbai, India), 4.7% clove gel (Pain Out Dental Gel, Colgate Palmolive India Ltd, Solan, India), 10% betel leaf extract gel, and ice were applied to each group for one min, followed by administration of infiltration anesthesia. Pain perception was analyzed during needle insertion. The Wong Bakers FACES pain rating scale (WBFPRS) was used for subjective assessment and the Sound, Eye, Motor (SEM) scale for objective assessment. Recorded values were tabulated and subjected to appropriate statistical analysis using SPSS software with a P value set at 0.05. Results: The clove oil and betel leaf groups demonstrated the highest WBFPRS scores, followed by the ice and lignocaine groups. The clove, betel leaf extract, and ice groups showed equal and highest SEM scores, followed by the lignocaine group. The mean WBFPRS and mean SEM scores were statistically significant. Conclusion: Betel leaf extract gel is effective in reducing pain and can act as an alternative topical anesthetic agent.

Quality characteristics of sausage with added pine needle powder (0%, 0.5%, 1.0%, 1.5%, 2.0%, and 2.5%) as an ingredient. The basic ingredients of sausage consisted of pork meat 60%, olive oil 20%, and ice water 20%. Sensory properties of sausage were analyzed by a sensory test, and the texture and color characteristics were measured using a texturometer and color meter, respectively. In the results of the sensory test, taste, texture, and overall preference were highest in the sample with added 1.5% pine needle powder. The sausage with added 1.5% pine needle powder was moderate in color intensity, pine needle flavor, and astringent taste. Hardness and gumminess of sausage were higher in 1.0% and 1.5% pine needle powder. However, springness and chewiness of sausage showed no significant differences. In terms of color intensity of sausage, L-value and a-value were lower and b-value was higher, depending on the pine needle powder amount. Development of off-flavor of sausage during storage was greater in 0% and 1.5% added sausages than in 2.0% sausage with increasing storage time. As a conclusion, sausages with added 1.5% and 2.0% pine needle powder were the most suitable for making functional sausage with added pine needle powder.

Purpose: The purpose of this study is to determine the level of pain related to a blood sugar test. Specifically, the study attempts to compare the varying degree of pains when different types of blood sugar test are used. Method: A sample of 56 subjects is composed of DM patients admitted to a medical ward of C university hospital in Gwangju. Data were collected from July, 2001 to December, 2001. The blood sugar tests were administered in four different ways: (1) the use of 27G needle only, (2) the use of 27G needle followed by ice-packed treatment, (3) the use of 27G needle after EMLA cream application, and (4) the use of lancet. The degree of pain is measured with a visual analogue scale and performed twice. Result: In both measures, the use of 27G needle only method is shown to cause the highest level of pain in comparison with the rest of methods (F=4.01, p=.01; F=8.14, p=.00). However, the differences in pain between time in all methods were not found to be significant (t=-.85, p=.40; t=.80, p=.42; t=.31, p=.75; t=.19, p=.85). Conclusion: The study results indicate that the method using lanceter is more recommendable than the use of 27G needle only method. Further research is needed to support the current study result with the use of different measurement scales and to determine effective methods of blood sugar test to lower pain and compliance.

The purpose of this study was to develop a computer operated automatic drip irrigation system for application in vinyl-house cultivation. The results can be summarized as follows: 1) The T-type ice compensation wire was used to measure the temperature. The voltage level measured up to 0.02 volt was used as input to an 8-bit A/D converter. 2) A specially devised tensiometer was used to content the watering system. When the needle of the pressure gauge reaches the lower threshold position it turns on the pumping system and turns off when it reaches higher threshold position. 3) In order to use the multiple gypsum blocks for one transducer, reed relays and a D/O board were used to make the sequential switching possible. 4) It was possible to automate the trickle irrigation system for the whole growth period of vinyl-house crops with the help of microcomputer. 5) In terms of furrow irrigation, the irrigation water consumption was the smallest, 2.8 times less than conventional method of surface trickle irrigation, 3.4 times less than subsurface trickle irrigation method. 6) In terms of productivity of cucumber, there was a drop in productivity when compared to furrow irrigation method, 7.2% for surface trickle irrigation, 27.4% for subsurface irrigation method.

Phlebotomy, a therapeutic method of bloodletting typically performed using a needle, has a traditional technique known as "Fasd." In this method, blood is extracted by creating a longitudinal incision on a vein (3-5 mm) with a surgical scalpel blade, usually blade No. 11. Due to the incision in the vessel wall, establishing hemostasis is more challenging compared to conventional methods. Hemostasis is usually achieved within minutes after Fasd. We present a case highlighting an uncommon yet significant complication of traditional phlebotomy. A 55-year-old man with no prior medical conditions underwent traditional phlebotomy at an academic traditional medicine clinic. Senior MD-PhD students in Iranian Traditional Medicine, under professor supervision, performed Fasd. A sterile scalpel blade No. 11 was used to create a longitudinal incision of approximately 4 mm on the patient's median basilic vein in the right hand. After removing 400 cc of blood, a pressure dressing was applied to the incision site. Despite attempts such as hand elevation, ice pack application, prolonged direct pressure, and tight elastic bandaging, bleeding from the incision persisted. After an hour of supportive therapy, hemostasis was eventually achieved within a few minutes using burnt cotton dressing (a traditional method for blood hemostasis). Following intravenous hydration, the patient was discharged in stable condition and reported no issues during the one-month follow-up. The traditional phlebotomy (Fasd) carries the risk of serious complications, including uncontrolled and prolonged bleeding. Further research on the efficacy and safety of burnt cotton dressing for controlling hemostasis is recommended.

Objective : There has been no known report on the pain shock after administering Korean bee-venom therapy. Three accounts of pain shock were observed at the Sangji university affiliated Oriental medicine clinic from July 2001 through September 2001. This thesis will inform clinical progression and cautions on administering Korean bee-venom therapy. Methods: We were able to witness different patterns of pain shock during the treatment of degenerative knee joint, progressive oral paralysis, and A.L.S. In order to reduce heat toxicity of the bee venom, needling points were first massaged with the ice for 10 minutes before injecting $0.1{\sim}0.2cc$ of the bee venom. Points of injection were ST36, LI11, LI4 and others. Pain shock occurred after injecting on inner xi-an, outer xi-an and LI4. The phenomena associated with pain shock was recorded in chronological order and local changes were examined. Results: Through examining 3 patients with the pain shock, we managed to observe clinical progression, duration, and time linked changes on specific regions. We also managed to determine sensitive needling points for the pain shock. Conclution: Following results were obtained from 3 patients with the pain shock caused by Korean bee-venom therapy from July 2001 to September 2001. 1. Either positive or negative responses were shown after the pain shock. For case 1, extreme pain was accompanied with muscular convulsion and tremble, ocular hyperemia, delirium, stiffening of extremities, and hyper ventilation which all suggest positive responses. For case 2 and 3, extreme pain was accompanied with facial sweating, asthenia of extremities, pallor face, dizziness, weak voice, and sleepiness which are the signs of negative responses. 2. The time required to recover to stable state took nearly an hour (including sleeping time) and there was no side effect. 3. Precautions required to prevent the pain shock includes full concentration from the practitioner, accurate point location, precise amount of injection, physiological condition and psychological stability of the patient 4. Coping with the pain shock should be similar with a needle shock, and since extreme pain is accompanied, sufficient psychological rest must be provided. 5. Pain shock occurs because the patient cannot tolerate stimulation on the needling point. Thus, symptoms were similar to the needle shock in addition to excruciating pain. Further investigation and research must be done to have better understanding of an immune response and the pain shock associated with Korean bee-venom therapy.

Purpose: The purpose of this study was to investigate the electrochemical characteristics of nanotubular Ti-25Nb-xZr ternary alloys for dental implant materials. Materials and Methods: Ti-25Nb-xZr alloys with different Zr contents (0, 3, 7, and 15 wt.%) were manufactured using commercially pure titanium (CP-Ti), niobium (Nb), and zirconium (Zr) (99.95 wt.% purity). The alloys were prepared by arc melting in argon (Ar) atmosphere. The Ti-25Nb-xZr alloys were homogenized in Ar atmosphere at $1,000^{\circ}C$ for 12 hours followed by quenching into ice water. The microstructure of the Ti-25Nb-xZr alloys was examined by a field emission scanning electron microscope. The phases in the alloys were identified by an X-ray diffractometer. The chemical composition of the nanotube-formed surfaces was determined by energy-dispersive X-ray spectroscopy. Self-organized $TiO_2$ was prepared by electrochemical oxidation of the samples in a $1.0M\;H_3PO_4+0.8wt.%$ NaF electrolyte. The anodization potential was 30 V and time was 1 hour by DC supplier. Surface wettability was evaluated for both the metallographically polished and nanotube-formed surfaces using a contact-angle goniometer. The corrosion properties of the specimens were investigated using a 0.9 wt.% aqueous solution of NaCl at $36^{\circ}C{\pm}5^{\circ}C$ using a potentiodynamic polarization test. Result: Needle-like structure of Ti-25Nb-xZr alloys was transform to equiaxed structure as Zr content increased. Nanotube formed on Ti-25Nb-xZr alloys show two sizes of nanotube structure. The diameters of the large tubes decreased and small tubes increased as Zr content increased. The lower contact angles for nanotube formed Ti-25NbxZr alloys surfaces showed compare to non-nanotube formed surface. The corrosion resistance of alloy increased as Zr content increased, and nanotube formed surface showed longer the passive regions compared to non-treatment surface. Conclusion: It is confirmed that corrosion resistance of alloy increased as Zr content increased, and nanotube formed surface has longer passive region compared to without treatment surface.

지리산 국립공원 종주 등산로는 노면이 만들어진 위치와 구배에 의해 평탄면형, 우곡형, 외벽형 및 비대칭 양벽형으로 구분되며, 노면의 배수 상태에 따라 유형 간 변화가 일어난다. 신속 측량법에 의한 종주 등산로의 형태 요소는 노폭 135.9cm, 깊이 23.6cm, 구배 $5.1^{\circ}$이며, 모든 노면은 압밀되어 있다. 노폭은 사면의 향과 조릿대 서식 밀도의 영향을 받으며, 대칭형 등산로보다 비대칭형 등산로의 노폭이 크다. 등산로 출현 시점을 1960년으로 간주하면, 등산로 횡단면에서의 연평균 침식 속도는 $68.9cm^2$로 노폭은 매년 2.7cm씩 넓어지고, 노면은 0.4cm씩 낮아진 것이 된다. 답압 이외에 서릿발 작용과 파이프류의 우세가 결합된 침식 프로세스가 등산로 확대를 주도하는 것으로 보인다.
