In preparing sodium alginates from sea tangle (Laminaria japonica) powder using the Mexican process, alkaline extraction, conversion to alginic acid and reversion to sodium alginates were used to increase purity. The effect of hot water treatment and dialysis on measuring the average molecular weight of sodium alginates were investigated. Intrinsic viscosity and average molecular weight of sodium alginates after dialysis were higher than those before dialysis. Average molecular weight of sodium alginates treated with hot water was higher than that without. Hot treatment has little effect on the ash content of sodium alginates. Ash content of sodium alginates before dialysis were $27-30\%$ those after dialysis were $10\%.$ After dialysis, Na content was highest $(89-91\%),$ K was $11-12\%,$ Ca was $1.9\%,$ and Mg was $0.05\%.$ Ash content of alginates had little effect on average molecular weight. SAV (slope of apparent viscosity) of alginates solution after dialysis showed higher values than before. SAV of the alginates with hot water treatment were higher than without treatment.

관찰연구를 이용하여 인과관계를 추론할 경우 무작위 통제시험과는 달리 교란변수로 인한 편향을 제어하기 위한 통계적 전략이 필요하다. 최근에는 성향점수(propensity score) 를 이용한 짝짓기나 원인변수의 역확률을 가중치로 사용하는 주변구조모형이 제안되어 사용되고 있다. 이러한 인과관계 추론은 처치(treatment)가 명확히 주어진 경우에 교란변수를 통제하고 그 처치가 결과에 미치는 영향을 평가하는 방법에 초점이 맞추어져 있다. 하지만 기존의 방법의 경우 원인변수인 처치가 직접관측이 가능한 범주형 변수이고 결과변수 또한 직접관측이 가능한 변수인 경우에만 사용할 수 있는 한계를 갖고 있다. 본 연구에서는 원인변수인 처치와 결과변수의 결괏값의 직접적인 관측이 어려운 경우, 측정오차를 고려한 잠재범주모형(latent class analysis)의 변수로 모형화 함으로써 잠재범주 간의 원인적 영향력을 추정하는 방법을 제시하고자 한다. 그리고 미국의 The National Longitudinal Study of Adolescent Health 자료를 이용하여, 약물사용의 잠재범주에 대한 청소년기의 비행(delinquency)이라는 잠재범주의 원인적 영향력을 추정하였다.

고차원 데이터의 인과 추론에서 고차원 공변량의 차원을 축소하고 적절히 변형하여 처리와 잠재 결과에 영향을 줄 수 있는 교란을 통제하는 것은 중요한 문제이다. 평균 처리 효과(average treatment effect; ATE) 추정에 있어서, 성향점수와 결과 모형 추정을 이용한 확장된 역확률 가중치 방법이 주로 사용된다. 고차원 데이터의 분석시 모든 공변량을 포함한 모수 모형을 이용하여 성향 점수와 결과 모형 추정을 할 경우, ATE 추정량이 일치성을 갖지 않거나 추정량의 분산이 큰 값을 가질 수 있다. 이런 이유로 고차원 데이터에 대한 적절한 차원 축소 방법과 준모수 모형을 이용한 ATE 방법이 주목 받고 있다. 이와 관련된 연구로는 차원 축소부분에 준모수 모형과 희소 충분 차원 축소 방법을 활용한 연구가 있다. 최근에는 성향점수와 결과 모형을 추정하지 않고, 차원 축소 후 매칭을 활용한 ATE 추정 방법도 제시되었다. 고차원 데이터의 ATE 추정 방법연구 중 최근에 제시된 네 가지 연구에 대해 소개하고, 추정치 해석시 유의할 점에 대하여 논하기로 한다.

Objectives : Research on the effect and satisfaction between Acupuncture Treatment, Physical Treatment and contemporary Treatments of Acupuncture and Physical of lumbago patients Methods : We separated lumbago patients into three groups. A group with only Acupuncture Treatment and a group with only Physical Treatment and a group with contemporary treatments of Acupuncture and Physical. Questionnaire survey and score of Visual Analog Scale(VAS) and Oswestry Disability Index(ODI) were examined for comparison. Results & Conclusion : 1. Of the 54 patients Acupuncture Teatment group had 17 patients with similar ratio of gender and the average age was 39.5 years old. For the Physical Treatment group the ratio of male was 75% of the 8 patients and had the youngest average age which was 29.1 years old and the group with contemporary Treatments the ratio of female was 62% of 29 patients and had the oldest average age which was 46.7 years old. 2. The Acupuncture Treatment group had the shortest treatment period because of many acute stage caused by lumber sprain and the improvement score was the best. The group of contemporary treatments had the longest history day and treatment period by serious disease like HIVD and spinal stenosis but the improvement score of VAS and ODI was good similar to the Acupuncture Treatment group. For the Physical Treatment group there was many patients with degenerative change but not severe pain. The VAS, ODI and the improvement score was the lowest before and after the treatment.

Objectives The purpose of this study is to analyze the clinical data of atopic dermatitis patients and to report the therapeutic effect of Jageum-Jung. Methods We conducted a retrospective study on the effects of treatment on atopic dermatitis patients who took Jageum-Jung from August 1, 2017 to December 20, 2017. The patients visited three times during the treatment period. The SCORAD Index score was measured and analyzed. Results Atopic dermatitis patients were 2 adults and 5 children. Both 2 adults were male (100%). Among the children, 1 child was a male (20%) and 4 children were females (80%). For adults, average age was 29.5 years, average weight was 72.75 kg, average height was 1.76 m and average BMI was $23.49kg/m^2$. For children, average age was 6.2 years, average weight was 23.92 kg, average height was 1.2 m and average BMI was $16.08kg/m^2$. The atopic dermatitis patients' average SCORAD Index score was 18.04 at first visit, 11.46 at second visit, and 7.64 at third visit. The scores lowered significantly after every visit. Conclusions The SCORAD Index in atopic dermatitis patients who took Jageum-Jung significantly decreased and it is expected that Jageum-Jung will be clinically effective in the treatment of atopic dermatitis.

The purpose of this experiment was to study the effect of varying levels of tryptophan on the performance and carcass character of broiler. Trial 1: Ninety-six, five-week-old male Hubbard chickens, average weight 1.97 kg, were used in the trial. All birds were allocated into 3 treatments of 32 birds each. Each bird was kept in an individual cage. The trial period was 3 weeks. Treatment 1: Tryptophan content 0.198%. Treatment 2: Tryptophan content 0.228%. Treatment 3: Tryptophan content 0.258%. Trial 2: Ninety-six, three-week-old male Hubbard chickens, average weight 1.23 kg, were randomly distributed into the following two treatments. Each treatment had 48 birds. Treatment 1: Tryptophan content 0.167%. Treatment 2: Tryptophan content 0.198%. Trial 3: Ninety-six, twoweek-old Hubbard chickens, average body weight 0.72 kg, were used in this experiment. There were three treatments as follows. Treatment 1. Tryptophan content 0.136%. Treatment 2. Tryptophan content 0.167%. Treatment 3. Tryptophan content 0.198%. The result of Trial 1 showed that the feed intake, performance, and carcass characteristics were not influenced by tryptophan content in the diet which between 0.198% and 0.258% (p>0.05). There was no significant difference (p>0.05) in feed intake in either treatment in Trial 2. However, weight gain, feed conversion efficiency, and most carcass characteristics in the 0.198% treatment were significantly better (p<0.05) than in the 0.167% treatment. There was a trend that feed intake increased with increasing level of tryptophan, but there was no significant difference in Trial 3. The weight gain and feed conversion efficiency were significantly reduced for the broiler in the 0.136% treatment. This series of experiment showed that broilers need about 0.198% of tryptophan.

Objectives : This study aims to evaluate the add-on effect of herbal bath combined with acitretin in patients with psoriasis. Methods : We searched randomized controlled trials(RCTs) reporting the effect of herbal bath and acitretin combined treatment for psoriasis in 10 electronic databases from their inception to January 2023. Study collection, data extraction, and risk of bias assessment were performed by two independent researchers. Data synthesis and risk of bias evaluation was conducted using Revman 5.4. Results : Ten RCTs with 1,008 subjects were included. Herbal bath and acitretin combined treatment group showed higher average total effective rate than acitretin alone group(RR 1.39; 95% CI: 1.15-1.68, P=0.0006, I² =0%). Herbal bath and additional treatments such as phototherapy(NB-UVB) and oral herbal medicine, combined with acitretin group also showed higher average total effective rate than acitretin alone group(RR 1.81; 95% CI: 1.47-2.22, P<0.00001, I² =43%). Herbal bath and phototherapy(NB-UVB) combined with acitretin group also showed higher average total effective rate than acitretin alone group(RR 1.51; 95% CI: 1.18-1.93, P=0.0009, I² =0%). The overall risk of bias of the included studies was unclear or of high risks. Conclusions : This review showed that the add-on of herbal bath combined with acitretin treatment could be more effective than acitretin alone treatment in patients with psoriasis. However, because of few included studies, heterogeneity between studies, and insufficient quality of included studies, further well-designed RCTs are needed to confirm the add-on effect of herbal bath on psoriasis.

Purpose: To evaluate the drainage effect of silk suture following aspiration of the bursa as an early treatment of chronic lateral malleolar bursitis. Materials and Methods: Thirteen cases, which have over two weeks of history and over one year of follow-up, were investigated. The average duration of follow-up was 16.4 months. The average symptom duration before introduction into this study was 7.8 weeks. With an aseptic technique, the aspiration of the bursa was done with 18G needle and syringe and then the insertion of silk suture through the aspiration needle was performed. The amount of drainage was identified two or three times in a week and stitch out was done at the cessation of drainage. Over one year follow-up, recurrence, infection, pain, and limitation of range of motion were investigated by telephone interview. Results: Redness around the insertion site of silk suture was found in all cases, but there was no development of active infection or recurrence. The average duration of treatment is 10.4 days. Conclusion: The drainage with silk suture following aspiration of the bursa is less invasive and very effective method in the early treatment of chronic lateral malleolar bursitis.

Objective: This study investigated the effect of fermented biogas residue (FBR) of wheat on the performance, serum biochemical parameters, and meat quality in pigs. Methods: We selected 128 pigs (the mean initial body weight was $40.24{\pm}3.08kg$) and randomly allocated them to 4 groups (1 control group and 3 treatment groups) with 4 replicates per group and 8 pigs per pen in a randomized complete block design based on initial body weight and sex. The control group received a corn-soybean meal-based diet, the treatment group fed diets containing 5%, 10%, and 15% FBR, respectively (abbreviated as FBR5, FBR10, and FBR15, respectively). Every group received equivalent-energy and nitrogen diets. The test lasted 60 days and was divided into early and late stages. Blood and carcass samples were obtained on 60 d. Meat quality was collected from two pigs per pen. Results: During the late stage, the average daily feed intake and average daily gain of the treatment groups was greater than that of the control group (p<0.05). During the entire experiment, the average daily gain of the treatment groups was higher than that of the control group (p<0.05). Fermented biomass residue did not significantly affect serum biochemical parameters or meat quality, but did affect amino acid profiles in pork. The contents of Asp, Arg, Tyr, Phe, Leu, Thr, Ser, Lys, Pro, Ala, essential amino acids, non-essential amino acids, and total amino acids in pork of FBR5 and FBR10 were greater than those of the control group (p<0.05). Conclusion: These combined results suggest that feeding FBR could increase the average daily gain and average daily feed intake in pigs and the content of several flavor-promoting amino acids.
