Purpose: This study investigated the effects of an eye care protocol (ECP) on patients in the intensive care unit (ICU). Methods: This study utilized a randomized controlled design. Participants were patients who met the inclusion criteria and were admitted to the ICU (36 in the experimental group and 38 in the control group). The experimental group received an ECP, while the control group received standard eye care, starting the day after admission, for a duration of 10 days. The ECP classifies the degree of eyelid obstruction into three stages based on the degree of exposure to the lower eyelid conjunctiva and cornea. The protocol included cleansing with normal saline gauze, administering eye drops, applying silicone and polyurethane films, and recommending consultation with an ophthalmologist if necessary. The effectiveness of ECP was assessed by analyzing tear volume, hyperemia, chemosis, and eye discharge. Data analysis was conducted using SPSS 27.0, employing the Mann-Whitney U-test and generalized estimating equations. Results: On day 5, the experimental group demonstrated a significant increase in tear volume in both eyes compared with the control group. However, no statistically significant differences were observed in the incidence of hyperemia, chemosis, and eye discharge on days 5 and 10 of the intervention. Conclusion: The application of the ECP in this study increased tear volume in ICU patients, thereby reducing discomfort caused by dry eyes. It has the potential to prevent complications such as damage to the surface of the eyeball resulting from decreased tear volume.

농산물의 효율적인 가공.저장은 농산물의 안정된 공급과 물가안정에 크게 기여하며, 부가가치 향상과 식품관련산업의 국제경쟁력 강화에도 필수적인 요건이라 할 수 있다. 호박은 전국 각지의 유휴지에서 별다른 시비나 농약의 사용없이 재배가능한 농산물로 vitamin C 및 vitamin A의 전구체인 carotene과 무기질, 식이섬유, 전분, 자당, 포도당 등이 풍부하다. 호박은 이뇨작용과 산후부종에 효과가 인정되어 널리 이용되고 있으며, 당뇨병, 야맹증, 각막건조증 등에도 효과가 있다. 국민의 생활수준이 향상되고 사회구조가 변화함에 따라 식품소비의 양상도 크게 변화하여 편의식과 건강 지향적인 가공식품의 수요가 급격히 증가하고 있으며, 이에 부응하여 건강식품에 관한 다각적인 연구가 많이 행해지고 있으나 미비한 실정이다. 호박은 특히 수분함량이 많고 조직의 연화현상 등으로 저장성이 낮아서 경제성이 떨어지므로 호박을 이용한 다양한 가공제품의 개발이 요구된다. 호박의 이용성을 검토하고, 나아가 호박의 부가가치 향상 및 경쟁력을 가진 지역특산물화를 위하여 기능성을 갖춘 건강음료개발을 시도하였으며, 이러한 음료의 유통중 품질변화를 모니터링하였다. 호박음료의 유통중 품질변화는 저장온도(20, 30, 40, 50, 6$0^{\circ}C$) 및 저장기간(0, 2, 4, 6, 8 week)에 따른 중심합성실험계획으로 실험을 행하여, 저장에 따른 당, 산, pH, 갈색도 및 관능적 특성에 대하여 반응표면분석을 하였다. 당도, 산도, pH 및 갈색도의 경우 저장시간에 영향을 많이 받는 것으로 나타났으며, 관능적 특성 중 전반적인 기호도에 있어서는 저장온도 및 저장시간에 영향을 많이 받는 것으로 나타났다. 당도, 산도, pH의 경우 저장온도 및 저장기간에 따라 큰 차이를 보이지 않았다. 갈색도의 경우 저장온도 51.1$0^{\circ}C$ 및 저장기간 7.33 week일 때 최대의 갈색도로 나타났다. 전반적인 기호도 있어서는 저장온도 32.52$^{\circ}C$ 및 저장기간 0.30 week일 때 우수한 것으로 나타났다.

Silicone hydrogel contact lenses developed as a continuous-wear modality are now used as a daily-wear contact lenses. The purpose of this study was to investigate the clinical performance in a group of successful long-term wearers of conventional hydrogel contact lenses when refitted with daily wear $O_2OPTIX$ silicone hydrogel lenses. Sixty-two wearers ($30.7{\pm}19.9$ months of prior lens wear) among sixty-five soft lens wearers refitted with $O_2OPTIX$ silicone hydrogel lenses were participated in this study finally. Subjective symptoms were scored and objective signs were graded using CCLRU scales during the study period. 98% of subjects were successfully refitted with the one base curve of $O_2OPTIX$, and 33.9% of subjects were needed more or less lens powers compared with their habitual lenses. Subjects reported a concurrent reduction in dryness, redness and tiredness compared with their habitual lenses and both subjective and objective evaluations showed that dryness, tiredness, itchiness, bulbar and limbal hyperemia were decreased and significantly decreased particularly for those subjects with greater baseline symptoms (p<0.0001). But corneal staining was increased and was seen in many subjects during the study (p<0.0001). Refitting existing soft contact lens wearers with silicone hydrogel contact lens could result in a decreased in dryness, redness and tiredness, particularly more effective for those subjects with greater baseline of those symptoms. When patients using conventional hydrogel materials switch to a silicone hydrogel material, the potential for increased corneal staining should be considered and over-refraction should be needed to give a best vision.

Purpose : The purpose of this study was to investigate the temperature changes of the ocular surface before and after cataract surgery using thermography of a thermal imaging camera. Methods : The study included 75 patients (75 eyes) aged from 50 to 79 years who underwent cataract surgery. In the past, those who underwent corneal-related surgery, wearing contact lens, disorder of tear secretion and taking medication for systemic disease were excluded from this study. The temperature changes of the eyeball surface were measured using a thermal imager (Cox CX series, Answer, Korea) following Tear Break Up Time (TBUT) test, Mcmonnies questionnaire and Schirmer's Test in real time, Results : While the temperature of preoperative ocular surface was $35.20{\pm}0.54^{\circ}C$ and that of postoperative temperature was $35.30{\pm}0.53^{\circ}C$, the difference was not significant. The temperature changes in the ocular surface were statistically significant at $-0.12{\pm}0.08{\Delta}$ ($^{\circ}C/sec$) before the surgery and $-0.18{\pm}0.07{\Delta}$ ($^{\circ}C/sec$) after the surgery. In comparison of the age groups, it was shown that the changes in the surface temperature before the surgery were from $-0.19{\pm}0.05{\Delta}$ ($^{\circ}C/sec$) to $-0.14{\pm}0.09{\Delta}$ ($^{\circ}C/sec$) in the 50s group, and from $-0.12{\pm}0.08{\Delta}$ ($^{\circ}C/sec$) to $-0.15{\pm}0.07{\Delta}$ ($^{\circ}C/sec$) in 60s group, and $-0.18{\pm}0.07{\Delta}$ ($^{\circ}C$) to $-0.12{\pm}0.08{\Delta}/sec$) in the 70s group, showing significant changes in the ocular surface temperature at all ages. Conclusion : Following the cataract surgery, all the indicators of dry eye syndrome were decreased, and eye surface temperature changes were significant. The thermography technique of the ocular surface would be expected to be useful for the evaluation of various dry eye syndromes because it is easy to evaluate dry eye syndrome noninvasively and can be quantified.
