  • Objectives : To characterize the thermal properties of traditional warm needle and new warm needle with various air flows as an important environmental factor and to suggest the necessity of maintaining suitable environment of clinics to maximize their efficacy. Methods : We measured the temperature characteristics of traditional moxa warm needle and new moxa charcoal warm needle by applying an automatic temperature acquisition system with thermocouples while external various air flows were supplied. Temperatures of two positions at the needle body were measured while a moxa cone burned. Typical temperature characteristics like peak temperature, duration, curve shape and the efficiency of the heat stimuli by heat amount analysis were executed. Results : Both warm needles showed similar temperature curve with an increase in the air flow. Peak temperature and duration of effective heat decreased with the air flow, as shown in indirect moxibustion on garlic. The temperature change pattern by the air flow became more apparent when the total combustion heat was compared with the effective heat. The values from two positions on the needle body were significantly different, showing a distance dependency from the heat source of warm needle acupuncture. Conclusions : Thermal properties of warm needle acupuncture was observed variously with surrounding air flow of 0.0 - 0.7 m/s. It emphasized the importance of environmental control as well as the warm needle itself such as heat source and needle. The latter has already been known to deliver designated heat to subjects. It also indicated the importance of education and skill of the practitioners of warm needle acupuncture.

  • This study was to investigate concentration characteristics of atmospheric PCBs in soil sample and pine needle at rural area. Profiles of PCB congener detected in pine needle and soil sample have a difference that low molecular PCBs mainly existed in pine needle, whereas high molecular PCBs were mainly existed in soil sample because of their different vapor pressure and octanol-air partitioning coefficient($K_{OA}$) of each congeners. Correlation coefficients(r) of PCB congeners simultaneously detected in soil and pine needle were significant (r>0.71, p<0.01), which showed that PCB congeners patterns of atmosphere could be estimated in using pine needle and soil sample indirectly. The contributions(%) of higher molecular PCBs(>penta-CB) to total PCBs in soil sample were higher than those of pine needle and the contribution of lower molecular PCBs(

  • Objectives : This study was conducted to observe the tip of needles which induce poor needle sensation upon injection of herbal acupuncture. Methods : Among the syringes used for herbal acupuncture, needles which cause poor sensation were collected and evaluated by SEM (scanning electron microscope) for changes in structure, existence of impure matters, physical damage, and etc. Results : 1. Various forms contributed to poor needle sensation. Bent needle body, damaged or crooked needle tip, and blunted tip 2. Poor needles could be made during the manufacturing process, during insertion of the needle into the vial(except for the lubricants), and repeated procedures with one needle at different regions. Conclusion : Poor needles induce unnecessary pain and discomfort not only to the patients but also to administrators during injection. Herbal acupuncture is a treatment technique injecting herbal extract on the meridian points, and strict quality check must be enforced to prevent occurrence of poor needles.

  • 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.

  • This study was conducted to investigate the effect of pine needle powder on antioxidant activity and the quality characteristics of Majakgwa (Korean traditional cookie). Majakgwa was prepared with different amounts of pine needle powder (in ratios of 0, 3, 6, 9 and 12% to the flour quantity). The antioxidant activity was estimated by DPPH free radical scavenging activity and by the total phenol content in pine needle powder and Majakgwa. For analyzing the quality characteristics, bulk density and pH of the dough, moisture content, volume, color, texture profile analysis and sensory evaluations were measured. The bulk density, volume, total phenol contents and DPPH free radical scavenging activity of Majakgwa significantly increased with increasing pine needle powder (p<0.001), whereas the pH of the dough, L values and b values of the Majakgwa significantly decreased with increasing pine needle powder content (p<0.001). The consumer acceptability score for the 6% pine needle Majakgwa ranked significantly higher (p<0.001) than those of the other groups in overall preference, flavor, taste, crispiness and color. Acid value and peroxide value was lower in Majakgwa with pine needle powder than control. From these results;we suggest that pine needle powder is a good ingredient for increasing consumer acceptability and functionality of Majakgwa.

  • This paper shows how to implement force reflection for a needle insertion problem. The target is a needle spine biopsy simulator for tumor inspection by needle insertion. Simulated force is calculated from the relationship of volume graphic data and the orientation and Position of the needle, and it is generated using PHANTOM$^{TM}$. To generate realistic force reflection, the directional force of the needle has been generated by tissue model. The other rotational force is generated using a pivot to keep the needle in the initial inserted direction after puncturing the skin. Since the used haptic device has limitation for generating high stiffness and large damping, scale downed model and digital filter are used to stabilize the system.m.

  • We have shown in Part I [1] of this study that medical needle-stick injuries are causing serious health problems to healthcare personnel and other professionals that require the attention of healthcare and textile researchers to develop new protective systems. Responding to such need, a needle force measurement device that is capable of measuring dynamic forces experienced by medical needles during needle penetration through protective articles was developed and described in part I. This paper reports the results of evaluation of protective woven fabrics from high performance fibers and standard and bifid medical needles using the force measurement system. The woven fabrics varied in cover factor, number of layers, and orientation angle. Standard and bifid needles with different gap widths were used to evaluate the resistance of the fabric to needle penetration.
